Why USB-Equipped Backpacks Are Essential for Modern Study Abroad Students
The modern study abroad experience is defined by mobility. You’re not just walking across campus—you’re navigating metro systems in Seoul, cycling through Amsterdam, and sprinting through Charles de Gaulle to catch a budget flight. Your devices are your lifeline: GPS for finding that hidden study spot, translation apps for grocery shopping, digital textbooks that weigh nothing, and video calls home that keep culture shock at bay. A USB port integrated into your backpack transforms dead time—commutes, layovers, between classes—into productive charging sessions without forcing you to stop and hunt for a wall outlet.
Beyond convenience, there’s a security dimension. Public USB charging stations in airports and train stations have become notorious for “juice jacking” attacks, where malicious actors compromise charging ports to steal data. A personal power bank connected to your own backpack’s USB pass-through keeps your devices charged while eliminating the need to plug into potentially compromised public infrastructure. In 2026, as cyber threats become more sophisticated, this simple feature provides both physical and digital peace of mind.
Understanding USB Port Technology in Backpacks
The Difference Between Pass-Through and Power Bank Integrated Ports
Most backpacks advertising USB charging fall into two distinct categories, and understanding the difference will save you significant frustration. Pass-through ports are simply a reinforced hole with a cable that runs from inside your bag to an external port. You supply your own power bank, connect it inside, and plug your device into the external port. This design offers maximum flexibility—you can upgrade your power bank as technology improves, replace a failed unit without ditching your entire backpack, and choose capacity based on your specific needs.
Integrated systems, conversely, come with a built-in power bank sewn into the backpack’s structure. While this sounds convenient, it creates several problems for study abroad students. The battery is typically lower capacity than aftermarket options, non-replaceable when it inevitably degrades after 18 months, and often uses proprietary charging cables that are impossible to replace in a foreign country. Worse, if the battery fails, you’re stuck with a dead weight and a useless feature. For international students who need reliability over multiple years, pass-through designs are overwhelmingly superior.
USB-A vs USB-C: What 2026 Standards Mean for You
By 2026, USB-C has become the universal standard for most new devices, but the transition isn’t complete. Your ideal backpack should feature both port types externally. Look for models with USB-C Power Delivery (PD) capability, which can deliver up to 100W—enough to charge a MacBook Pro or gaming laptop. The USB-A port remains relevant for older peripherals, borrowing a friend’s charger, or powering low-draw devices like wireless earbuds.
Check the internal cable quality carefully. Cheap backpacks use thin-gauge wires that can’t handle fast charging, creating resistance that generates heat and slows charging to a crawl. Quality models advertise “fast-charge compatible” or specify wire gauge (22AWG or thicker is ideal). The internal cable should be replaceable—some premium designs use standard USB connections at both ends rather than hardwired solutions, allowing you to swap a damaged cable without replacing the entire bag.
Key Features to Evaluate Beyond the USB Port
Capacity and Size: Balancing Mobility and Storage
The sweet spot for study abroad backpacks typically falls between 25-35 liters. Below 25 liters, you’ll struggle to fit a day’s worth of gear plus a light jacket or groceries. Above 35 liters, you risk exceeding airline personal item dimensions, forcing you to check the bag on budget carriers like Ryanair or EasyJet—a costly mistake that can exceed $50 per flight.
Consider your specific program structure. Architecture students hauling drafting tools need more space than literature majors carrying a single tablet. Medical students on clinical rotations require separate compartments for scrubs and study materials. The key is modularity: compression straps that shrink the bag when lightly packed, but expand when you’re hauling souvenirs back from weekend trips. Look for articulated designs that maintain a slim profile against your back while offering expandable front compartments.
Laptop Compartment Specifications
Your laptop compartment needs more than just padding—it requires a false bottom. This design feature suspends your laptop above the bag’s base, protecting it from the inevitable drop when you set your bag down harder than intended on cobblestone streets. The compartment should be accessed from the back panel, not the top, making it harder for thieves to quickly snatch your device in crowded markets.
Measure your laptop, including any protective case you use. Many students buy hardshell cases after arrival, which add 2-3mm of thickness. A compartment advertised as “15-inch laptop compatible” might fit a naked MacBook but struggle with a ruggedized case. Look for specifications that list maximum dimensions in centimeters, not just screen size, and add a 1cm buffer for international plug adapters and cases.
Durability Materials and Weather Resistance
Study abroad subjects your backpack to abuse that campus life never replicates. Mediterranean sun fades and weakens nylon. Southeast Asian monsoons test waterproofing daily. Scandinavian winters make zippers brittle. Materials matter profoundly.
Ballistic nylon (1680D) offers the best tear resistance for high-abrasion areas like the base and corners. For the main body, 500D-1000D Cordura or recycled PET fabric provides an optimal balance of weight and durability. Avoid leather—it’s heavy, requires maintenance, and can develop mold in humid climates.
Weather resistance goes beyond fabric. YKK AquaGuard zippers are the gold standard, featuring a water-repellent coating that prevents rain from seeping through the teeth. Taped seams on internal compartments add redundancy. But here’s the critical detail: “water-resistant” and “waterproof” are vastly different. A truly waterproof backpack needs an IPX6 rating or higher, which few achieve. For most students, water-resistant with a packable rain cover offers better versatility—the cover adds 100% waterproofing when needed but saves weight when the forecast is clear.
Ergonomics and Comfort for Daily International Commutes
Strap Design and Weight Distribution
A 15kg load feels dramatically different after a 45-minute standing commute on Tokyo’s Yamanote Line versus a 10-minute walk to a lecture hall. Look for straps with at least 5cm width at the shoulders, tapering to prevent armpit chafing. The foam density matters more than thickness—EPE foam (expanded polyethylene) maintains its cushioning properties longer than cheaper PU foam, which compresses permanently after a few months of heavy use.
Load lifter straps, those small adjustable straps connecting the top of the shoulder straps to the bag’s upper back panel, are non-negotiable for heavier loads. They pull the bag’s weight closer to your body’s center of gravity, reducing the backward pull that strains your lower back. Sternum straps should be vertically adjustable by at least 10cm to accommodate different torso lengths—crucial for both petite students and tall travelers.
Back Panel Ventilation Systems
The difference between arriving at class fresh versus sweat-soaked often comes down to back panel design. Simple padded panels trap heat and moisture, creating the dreaded “sweat rectangle” on your shirt. Advanced designs use suspended mesh that creates a 2-3cm air gap between your back and the bag, allowing convective cooling.
In 2026, some manufacturers incorporate phase-change material (PCM) into back panels—the same technology used in spacesuits. These materials absorb excess heat when you’re hot and release it when you cool down, maintaining a consistent temperature. While expensive, this feature is transformative for students in hot climates or those prone to back sweating. For most, a well-designed ventilated panel with vertical airflow channels provides 80% of the benefit at a fraction of the cost.
Security Features for International Travel
Anti-Theft Zippers and Locking Mechanisms
Standard zippers can be opened with a ballpoint pen in seconds, a common pickpocket technique in tourist-heavy European cities. Look for interlocking zipper pulls that can be looped through a small carabiner or lock. Better yet, some designs feature puncture-resistant zippers where the coil is hidden behind a fabric lip, making pen attacks impossible.
Lockable sliders are essential for hostel living. While TSA locks are useless for theft prevention (they’re standardized and easily picked), they deter opportunistic theft from dorm mates. The real security comes from lockable compartments that are separate from the main storage—thieves who slash your bag open often grab the first valuable they see and run. A hidden pocket against your back panel for your passport and emergency cash can save your entire semester if the main compartment is compromised.
RFID Protection and Data Security
RFID-blocking pockets have become standard marketing fluff, but they serve a legitimate purpose in specific contexts. While contactless credit card skimming is rare, it’s trivial to execute in crowded metro stations. A single pocket lined with RFID-blocking material (typically copper or aluminum mesh) provides peace of mind for your primary credit card and passport.
More importantly, consider backpacks with a “radio silent” pocket that blocks all signals, including cellular and GPS. This isn’t just for paranoia—when crossing borders, some countries have begun scanning devices remotely. A signal-blocking pocket ensures your phone can’t be pinged or tracked when stored, giving you control over your digital footprint. For the ultra-cautious, some designs feature Faraday cage compartments that require opening a specific flap to access, making surreptitious scanning impossible.
Organization Systems for Academic and Travel Gear
Modular Compartments and Adaptability
The ideal study abroad backpack functions as three bags in one: a daily academic carrier, a weekend travel pack, and a mobile office. Modular organization makes this possible. Look for removable tech pouches that can be pulled out for TSA screening without unpacking your entire bag. Some designs feature a detachable daypack that zips off the main bag—perfect for leaving heavy textbooks at your accommodation while exploring.
Vertical organization beats horizontal every time. Pockets that run top-to-bottom allow you to see all contents at a glance, rather than stacking items horizontally where the bottom layer becomes inaccessible. This is particularly valuable for stationery, cables, and adapters. The best designs use contrasting interior colors (bright orange or lime green) that make black cables and chargers visible in dim hostel lighting.
Quick-Access Pockets for Travel Documents
When you’re fumbling for your boarding pass at a train station in a country where you don’t speak the language, pocket placement becomes critical. A dedicated travel document pocket should be accessible without removing the backpack—typically located on the top panel or side. It should be large enough for a passport, boarding pass, student ID, and a few cards, with a bright interior to prevent leaving items behind.
The pocket should have a water-resistant zipper and be RFID-protected. Some 2026 models feature transparent touchscreen-compatible windows, allowing you to display QR code boarding passes or transit cards without removing them. This small convenience speeds up transit and reduces the risk of dropping documents in crowded stations.
Power Bank Compatibility and Charging Capacity
Understanding mAh Ratings and Real-World Usage
Marketing materials love to tout massive milliampere-hour (mAh) numbers, but the physics of charging tells a more nuanced story. A 20,000mAh power bank sounds impressive, but due to voltage conversion losses and the fact that your devices operate at 3.7V while the power bank outputs at 5V, you’ll only get about 13,000mAh of usable capacity—roughly 3-4 phone charges or 1.5 laptop charges.
For study abroad, calculate your daily consumption. A typical day might include: phone (3,000mAh), tablet (7,000mAh), wireless earbuds (500mAh), and smartwatch (300mAh). That’s over 10,000mAh before factoring in laptop needs. A 26,800mAh power bank hits the sweet spot—it’s the maximum capacity allowed on international flights without special approval (100Wh limit), providing a comfortable 2-day buffer.
Pass-Through Charging Optimization
The best pass-through systems include a cable management channel that prevents the internal USB cable from being pinched by heavy textbooks. Look for a dedicated power bank pocket located at the bag’s center of gravity, typically against the back panel near the base. This placement prevents the heavy battery from making the bag top-heavy and uncomfortable.
Some advanced designs feature a secondary internal USB port that allows you to charge the power bank itself while it’s connected to the external port. This creates a “daisy chain” where you can plug the entire bag into a wall outlet at night, charging both the power bank and any devices connected to the external ports simultaneously. This eliminates the daily ritual of removing and reinserting your power bank, reducing wear on both the bag and the battery.
Durability Testing Standards to Look For
IP Ratings and Weatherproofing Explained
The Ingress Protection (IP) rating system provides objective measures of dust and water resistance. An IPX4 rating means the bag can handle splashes from any direction—sufficient for light rain. IPX6 withstands powerful water jets, essentially heavy downpours. IPX7 indicates submersion protection up to 1 meter for 30 minutes, which is overkill for most academic use but valuable if you’re kayaking in New Zealand between classes.
The “X” in these ratings represents dust protection, which is actually more relevant for backpack longevity. An IP5X rating means dust ingress won’t interfere with operation—critical in dusty environments like Marrakech or Delhi, where fine particles can infiltrate zippers and abrade fabric from the inside. For study abroad, aim for IP54 as a baseline, with IP65 for students heading to particularly wet or dusty regions.
Stress Point Reinforcement
The most common failure points are the shoulder strap attachments, zipper ends, and base corners. Quality manufacturers bar-tack these areas with X-shaped stitching using bonded nylon thread that has a breaking strength of over 20kg. Turn the bag inside out and examine these points—if you see simple straight stitching or loose threads, keep shopping.
The base deserves special attention. Look for a double-layer construction with a replaceable skid plate. This thick piece of high-density plastic or rubber protects the bag’s bottom from abrasion when you set it down on rough surfaces. Some designs allow you to unscrew and replace this plate, effectively doubling the bag’s lifespan. The base should also have small feet that elevate the bag slightly, preventing moisture from wicking up when you place it on wet ground.
Style and Professional Aesthetics
Campus to Corporate Versatility
Your backpack needs to transition from a lecture hall in Sydney to an internship interview in London without looking out of place. The “tech bro” aesthetic of hyper-minimalist black bags with orange zippers screams tourist and can feel immature in professional European settings. Conversely, a stuffy leather briefcase is impractical for daily campus life.
The solution lies in material choice and hardware finish. Matte black or deep navy ballistic nylon with gunmetal hardware strikes the right balance—professional enough for a corporate environment, durable enough for daily abuse. Avoid bright colors for the main fabric; instead, choose a neutral base with a single pop of color on the interior lining or zipper pulls. This allows you to express personality while maintaining a mature appearance.
Cultural Appropriateness in Different Regions
Backpack culture varies dramatically by region. In Japan, oversized, military-style packs are common among students and won’t draw attention. In Italy, however, the same bag might be seen as aggressive or overly casual. Scandinavian countries value minimalist, functional design—bulky bags with excessive straps and MOLLE webbing look out of place.
Research your host country’s norms. If you’re heading to multiple countries, choose a design that errs on the side of understated elegance. A sleek 28-liter pack in charcoal gray works from Berlin to Bangkok. Additionally, consider how the bag wears with different attire. It should look natural with both a winter coat and a summer t-shirt, adapting to seasonal changes without clashing.
Airline Compatibility and Travel Features
Carry-On Size Restrictions by Region
Budget airlines are the bane of study abroad students, and their size restrictions are getting stricter. Ryanair’s personal item limit is 40x20x25cm, while Wizz Air allows 40x30x20cm. A backpack that exceeds these dimensions by even 1cm can cost you €50-€100 in fees. The trick is finding a bag that compresses to these sizes when needed but expands for daily use.
Look for bags with hideaway straps and a streamlined profile. When cinched down with compression straps, a 30-liter bag can shrink to meet personal item requirements. Some designs include a separate “travel skin”—a thin cover that zips over the backpack, smoothing out protruding pockets and straps to create a rectangular shape that satisfies the most stringent airline gate agents.
Luggage Pass-Through Sleeves
That trolley sleeve isn’t just for business travelers. When you’re hauling two months of luggage across King’s Cross Station to catch a train to your host university, being able to stack your backpack on your rolling suitcase is transformative. The sleeve should be made of durable material and positioned so the backpack sits high enough that it doesn’t drag on the ground or bump your heels.
The best designs feature a zippered closure on the sleeve, allowing you to convert it into a pocket when not in use. This dual functionality means you’re not sacrificing storage space for a feature you’ll only use during initial travel and semester breaks. The sleeve should be wide enough to accommodate the largest suitcase handles (up to 17cm) without stretching or tearing.
Sustainability and Ethical Manufacturing
Recycled Materials and Carbon-Neutral Production
The environmental impact of your backpack choice extends beyond materials. Many “recycled” bags simply use PET fabric made from bottles, which is commendable but only addresses part of the lifecycle. True sustainability includes water usage in manufacturing (dyeing fabric is water-intensive), carbon emissions from shipping, and end-of-life recyclability.
Look for bluesign® certification, which ensures the entire manufacturing process meets strict environmental standards. Some manufacturers now offer carbon-neutral shipping and participate in 1% for the Planet. For study abroad students who often develop heightened environmental awareness during their travels, aligning your gear choices with your values adds meaning to your experience.
Repairability and End-of-Life Programs
A backpack that can be repaired is infinitely more sustainable than one that must be replaced. Check if the manufacturer sells replacement buckles, straps, and zipper pulls. Some offer free repair clinics in major cities worldwide—a godsend when you’re in Buenos Aires and a shoulder strap fails. Brands that provide detailed repair manuals and sell spare parts empower you to fix issues with a simple sewing kit.
Take-back programs are another indicator of responsible design. When your backpack finally reaches end-of-life after years of use, manufacturers that accept it back for material recycling ensure it doesn’t end up in a landfill in your host country. This is particularly important in regions with limited recycling infrastructure.
Warranty and International Support
Global Warranty Coverage Nuances
A lifetime warranty is worthless if it only covers defects in the USA and you’re studying in Australia. Read the fine print carefully. Some warranties are voided if the product is “used for commercial purposes”—which could be interpreted to include unpaid internships. Others require you to ship the product to a specific service center at your own expense, which can cost more than the bag itself for international students.
Look for manufacturers with authorized repair centers on multiple continents. Brands that partner with local outdoor gear shops for warranty service often provide faster, cheaper resolutions. Email customer service before purchasing and ask specifically about warranty service in your host country. Their response time and clarity will tell you everything about how they’ll treat you when you actually need help.
Customer Service Accessibility Abroad
Time zone differences can make warranty claims excruciating. A company with 24/7 chat support or email-based claim systems is essential. Save all warranty documentation digitally—photograph your receipt and registration card, and store them in cloud storage accessible from anywhere. Some manufacturers now use blockchain-based warranty registration that’s impossible to lose and can be verified instantly worldwide.
Consider purchasing from a retailer in your host country, even if it costs slightly more. Local consumer protection laws often provide stronger rights than US warranties, and dealing with a physical store for returns or exchanges is infinitely easier than international shipping. Amazon’s international sites can be a middle ground, offering local return addresses while maintaining English-language support.
Price Tiers and Value Proposition
Budget vs Premium: What Actually Matters
The $60-$80 range can get you a functional USB backpack with decent materials and basic features. These bags typically last 12-18 months of heavy use before showing significant wear. For a single semester abroad, this might be sufficient. However, for year-long programs or multi-year use across multiple trips, investing $150-$250 pays dividends in durability, comfort, and features.
The premium tier ($250-$400) offers diminishing returns for most students. You’re paying for brand prestige, marginal weight savings, and exotic materials. The sweet spot for study abroad is $120-$180, where you get YKK zippers, durable fabric, ergonomic design, and thoughtful organization without the luxury markup. This price range also tends to offer the best warranty support.
Hidden Costs to Factor In
That budget backpack isn’t as cheap as it seems. Add $20 for a rain cover (often included in premium models), $15 for a cable organizer that should have been built-in, and $30 for a replacement power bank when the cheap included one fails. Suddenly, your $70 bag costs $135 and still lacks ergonomic straps.
Premium bags often include TSA-friendly laptop compartments that save time and stress at security. They feature pass-through ports with quality cables that won’t need replacement. Their durability means you won’t be buying a replacement mid-semester when a strap fails in a foreign country where shipping is expensive and options are limited. Calculate total cost of ownership over your entire program duration, not just the purchase price.
Maintenance and Care for Longevity
Cleaning Tech Components Safely
The USB port itself requires maintenance. Dust and lint accumulate in the port recess, creating a fire hazard with high-current charging. Use compressed air monthly to clear debris. Never clean with liquid cleaners, which can wick into the internal cable and cause corrosion. If the port becomes loose—a common failure mode—tighten the mounting screws immediately to prevent cable damage.
For fabric cleaning, avoid machine washing. The agitation destroys waterproof coatings and can damage internal cable routing. Instead, spot clean with mild soap and a soft brush. For deep cleaning, use a bathtub with lukewarm water and tech wash (a detergent that maintains DWR coatings). Rinse thoroughly and air dry completely before use—moisture trapped in padding can cause mildew and electrical issues.
Battery Safety and Storage
Power banks have specific storage requirements that most users ignore. Never store them fully charged for extended periods—this degrades battery capacity. For summer breaks when the bag sits unused, discharge to 40-50% and store in a cool, dry place. Extreme temperatures, common in unairconditioned dorms or left in cars, can cause thermal runaway.
Inspect your power bank monthly for swelling or damage. A puffed battery is a fire risk and must be disposed of immediately. Many universities have battery recycling programs—use them rather than throwing batteries in hostel trash. When flying, always carry power banks in your carry-on, never checked luggage, and tape over the terminals to prevent short circuits.
Future-Proofing Your 2026 Purchase
Emerging Tech Integration
The backpack of 2026 is beginning to integrate with smart ecosystems. Some models feature Bluetooth-enabled lost-and-find tags sewn into the lining, trackable through your phone. Others have solar panels integrated into the front pocket, providing trickle charging during long days of exploration—though current efficiency means you’ll get maybe 10-15% phone charge per day of full sun.
More practically, look for modular port systems. Some manufacturers now sell upgrade kits that let you swap USB-A ports for newer standards as they emerge. A bag with a standardized cutout (similar to how PC cases have standardized fan mounts) ensures you won’t be stuck with obsolete tech in 2027 when USB-D inevitably arrives.
Modular Upgrade Systems
The most future-proof approach is a backpack that accepts aftermarket accessories. MOLLE (Modular Lightweight Load-carrying Equipment) webbing, originally military tech, has been adapted for civilian use. It allows you to add pouches, water bottle holders, and tech organizers exactly where you want them. For study abroad, this means you can reconfigure your bag for different phases of your journey—add a camera cube for the sightseeing month, then swap in a document organizer for internship season.
Some brands have created proprietary modular systems with snap-in organizers that can be moved between different bags in their line. This ecosystem approach means your investment in organization accessories isn’t lost if you upgrade your main bag later. For students on tight budgets, this incremental upgrade path is more sustainable than buying a completely new bag when needs change.
Frequently Asked Questions
Q1: Can I bring a backpack with a built-in power bank on all international flights?
Yes, but the power bank must not exceed 100Wh (approximately 26,800mAh) and must be carried in your carry-on luggage, never checked. Always declare it at security if asked, and ensure terminals are protected from short circuits. Some airlines in Southeast Asia have stricter limits, so check specific carrier rules before flying.
Q2: How do I clean my backpack’s USB port if it stops working?
First, use compressed air to remove debris. Check that the internal cable connection hasn’t loosened. If the port is physically damaged, most quality bags allow you to replace just the port assembly—contact the manufacturer for parts. Never use liquid cleaners or metal tools inside the port, as this can damage contacts and create safety hazards.
Q3: Are USB backpacks worth the extra cost compared to a regular bag plus external battery?
For study abroad, absolutely. The integration prevents cable damage, keeps your power bank secure, and allows charging while walking—critical when navigating unfamiliar cities. The cost premium is typically $20-$40 over a comparable non-USB bag, which is less than replacing one damaged cable or lost power bank.
Q4: What’s the most common failure point on USB backpacks during extended travel?
The internal cable where it bends at the port entrance fails first, usually after 12-18 months of heavy use. Prevent this by choosing a bag with a replaceable cable and reinforced strain relief. Store the cable loosely coiled rather than sharply bent, and avoid yanking cords from the external port.
Q5: Can I use any power bank with my backpack’s USB port?
Yes, any standard USB power bank works, but match the cable type. If your bag has a USB-C port, ensure your power bank has USB-C PD output for fastest charging. Some ultra-compact power banks have short cables that may not reach the internal routing—measure before buying or choose a bag with an internal extension cable.
Q6: How do I know if a backpack’s USB port supports fast charging?
Check the internal cable specifications in the product details. Look for “USB 3.1” or “USB-C PD” compatibility. The cable gauge matters—22AWG or thicker supports higher currents. If the manufacturer doesn’t specify, assume it’s standard speed. You can also test with a USB power meter after purchase; if charging speed is significantly slower than plugging directly into the power bank, the cable is the bottleneck.
Q7: Should I get a backpack with solar charging for study abroad?
Solar charging sounds appealing but remains impractical for most students. Current panel efficiency means you need 6-8 hours of direct sun for a single phone charge, and the added weight and rigidity compromise bag comfort. It’s only worthwhile for students doing extensive fieldwork in consistently sunny regions, and even then, a high-capacity power bank is more reliable.
Q8: How do I prevent theft of my power bank from the backpack’s internal pocket?
Choose a bag where the power bank pocket is positioned against your back panel and requires opening the main compartment to access. Some designs include a small leash or clip inside the pocket to secure the battery. In high-risk areas, consider a small combination lock through the zipper pulls of the main compartment—opportunistic thieves look for easy grabs, not locked bags.
Q9: Will a USB backpack’s charging feature work after going through airport security repeatedly?
Yes, the X-ray machines and metal detectors don’t affect the charging functionality. However, always remove your power bank and place it in a separate bin—security may need to inspect it. The repeated opening and closing of compartments can loosen cable connections over time, so check internal connections after each major trip and tighten any loose screws.
Q10: Can I upgrade the USB port on my backpack if new technology comes out?
Some premium modular bags allow port replacement, but most have fixed ports. Future-proof by choosing a bag with a simple pass-through design where only the cable is internal—you can always thread a new cable type through the existing port hole. For true upgradeability, look for bags with a removable port bezel that can be swapped for different connector types as standards evolve.
