Laptop backpacks with charging ports solve one of the most annoying parts of modern commuting: a phone dying mid-transit with no outlet in sight. All eight backpacks here include a built-in USB port, but they differ widely in laptop protection, anti-theft features, capacity, and whether the charging cable is actually convenient to use. The NUBILY 17.3 Inch Waterproof Backpack earns the top spot for combining a TSA-friendly layout, anti-theft design, and a roomy main compartment at a mid-range price. The Swissdigital Design SD803-02 is the strongest premium pick with the most polished hardware, while the FENGDONG Waterproof Backpack delivers the best budget value if you just want reliable charging on a commute. Keep reading for the full breakdown of tradeoffs, including which bags skip the power bank entirely and which ones lug around more weight than their features justify.

Key Takeaways
- None of these backpacks include a power bank — every USB port here is just a pass-through cable, so you supply your own battery, which affects the real cost of the cheap options.
- The NUBILY and Swissdigital models separated themselves through travel features (TSA lay-flat design, luggage straps), while budget picks like FENGDONG and YALUNDISI are commute-only bags.
- Anti-theft claims vary hugely: BANGE, NUBILY, and WENIG have genuine hidden-zipper or lock designs, while cheaper bags only hide the USB port itself.
- The 17.3-inch bags (FENGDONG, Goloni, NUBILY) all run bulky and heavy — commuters who carry less should prioritize the slimmer 15.6-inch WENIG or LOVEVOOK instead.
- The YALUNDISI stands out as the only style-first option with a vintage leather-look finish, but it sacrifices water resistance and padding compared to sportier rivals.

More Details on Our Top Picks
FENGDONG Waterproof Travel Laptop Backpack 17.3 inch
FENGDONG’s 17.3-inch backpack delivers the core charging-port package at a budget-friendly price, and that’s exactly why it earns the value slot. At just 1.8 pounds, it’s noticeably lighter than the BANGE anti-theft model, which weighs a full pound more before you’ve packed anything. The seven compartments and dual USB/headset ports cover the essentials for commuters and students who want organization without paying a premium.
The tradeoffs are real, though. Water resistance here means light rain protection, not the sealed YKK-zipper construction BANGE offers — sustained soaking is off the table. And unlike pricier options, there’s no lock or anti-theft hardware, so travelers concerned about pickpockets should spend more elsewhere.
Pros:- Lightest 17.3-inch option in this lineup at 1.8 pounds
- Seven compartments keep work and travel gear separated
- Both USB and headphone ports included at a low price point
- Fits laptops up to 17.3 inches
Cons:- Water resistance won’t handle sustained rain or soaking
- No anti-theft lock or hidden zippers
- Fewer pockets (4) than the LOVEVOOK’s 34-pocket organization
Best for: Budget-conscious students and commuters with larger laptops who want basic weather protection and charging convenience
Not ideal for: Travelers visiting rainy climates or high-theft areas — the water resistance is light-duty and there’s no anti-theft lock
- External Dimensions:18.11″H x 12.6″L x 8.3″W
- Laptop Compatibility:Up to 17.3 inches
- Storage Volume:30 liters
- Weight:1.8 pounds
- Material:Polyester, Oxford fabric
- Water Resistance:Water resistant
- Compartments:7 compartments, 4 pockets
Our verdict“The smart pick if you want charging capability and big-laptop capacity without spending much, as long as your weather and security risks are mild.”
BANGE Anti-Theft Backpack, 17 Inch Laptop Backpack with USB 3.0
Where the FENGDONG leaves off, BANGE picks up: this is the security-first choice in the roundup. The password lock and waterproof YKK zippers create a genuinely hardened package that FENGDONG and Goloni simply don’t match, and the USB 3.0 port means faster pass-through charging than the standard ports on the YALUNDISI or LOVEVOOK. Nine compartments edge out most rivals for organization depth.
The cost of all that protection is weight — at 2.8 pounds empty, it’s the heaviest bag here, and fully packed it becomes a genuine shoulder workout. Compared with the LOVEVOOK, which is nearly a pound lighter with more storage volume, BANGE trades comfort for security. Care is also fussier: hand wash only, and the lock adds a step to every access.
Pros:- Password lock and anti-theft design for genuine security
- Waterproof YKK zippers seal out rain better than water-resistant rivals
- USB 3.0 port charges faster than standard USB ports in this lineup
- Nine compartments offer deep organization for travel gear
Cons:- Heaviest bag in the roundup at 2.8 pounds empty
- Hand wash only, and the lock slows everyday access
- Not suitable for children under 12
Best for: International travelers and urban commuters who prioritize theft protection and fast USB 3.0 charging over lightweight comfort
Not ideal for: Daily commuters with long walking routes or back issues — the 2.8-pound empty weight compounds quickly when loaded
- Dimensions:12.6″D x 6.3″W x 18.9″H
- Laptop Compatibility:Up to 17.3 inches
- Capacity:30 liters
- Weight:2.8 pounds
- USB Port:USB 3.0 fast charging
- Lock Type:Password lock
- Zipper:Waterproof YKK zipper
- Material:Oxford, Polyester
Our verdict“Buy this if theft risk and weather sealing matter more to you than weight — it’s the armored option among softer competitors.”
Goloni Travel Laptop Backpack, Water-Resistant 17.3 Inch USB Charging Bag
Goloni’s all-black commuter bag lands in the sensible middle of this lineup — more organized than the basic FENGDONG, lighter and less fortress-like than the BANGE. Its anti-theft hidden zippers give it a security edge over FENGDONG without BANGE’s added lock weight, and the padded straps make it the more comfortable choice for daily wear-and-tear than either.
The honest drawback is transparency: no published dimensions or weight, which makes fit planning a guessing game compared with FENGDONG’s fully specified sizing. Internal organization details are thin too — five compartments sounds fine, but there’s less confidence about pocket layout than with LOVEVOOK’s 34-pocket breakdown. This pick makes the most sense for buyers who want a dependable, understated work bag and aren’t chasing spec-sheet precision.
Pros:- Dedicated 17.3-inch laptop compartment with padded protection
- Hidden anti-theft zippers without the bulk of a lock system
- Padded straps suited to long daily carries
- Understated all-black styling appropriate for office settings
Cons:- No published dimensions or weight for pre-purchase planning
- Limited detail on internal organization compared with rivals
- No warranty information provided
Best for: Office commuters who want a low-key, professional-looking bag with hidden-zipper security and comfortable padded straps
Not ideal for: Detail-driven buyers who need exact dimensions and weight before purchasing — the missing specs make comparison shopping harder
- Laptop Compatibility:Up to 17.3 inches
- Capacity:Large
- Water Resistance:Water resistant
- Material:Polyester
- Compartments:5 compartments, 6 pockets
- Straps:Padded shoulder straps
- Charging:Built-in USB port
Our verdict“A solid middle-ground commuter bag if you trust the brand enough to buy without full specs — organized enough for work, light enough for daily use.”
LOVEVOOK Laptop Backpack for Women with USB Charging Port
If pocket count is your metric, LOVEVOOK wins outright — 34 pockets dwarf every other bag here, including BANGE’s nine compartments. Combined with a 34-liter volume (the largest in this batch), this option suits over-packers and organization obsessives who want a place for cables, chargers, cosmetics, and documents alike. The shock-resistant laptop strap adds protection FENGDONG doesn’t offer, and at 1.93 pounds it stays manageable despite the capacity.
Against the YALUNDISI, which shares the women-focused styling, LOVEVOOK offers more volume and structure but less charm — it reads more utility bag than accessory. The four compartments (versus 34 pockets) mean the main spaces are large while pockets do the sorting, which won’t suit everyone’s packing style. And as with nearly all bags here, the power bank is not included.
Pros:- 34 pockets offer the most granular organization in the roundup
- Largest capacity here at 34 liters
- Shock-resistant strap secures the laptop in addition to padding
- Lightweight for its size at 1.93 pounds
Cons:- Power bank not included despite the charging focus
- Hand wash only
- Larger silhouette than slim work bags like the WENIG
Best for: Women who carry a lot — students and working professionals who want maximum pocket-level organization and a true 34-liter capacity
Not ideal for: Minimalists and light packers — 34 pockets and 34 liters is overkill that adds bulk to daily carries
- Dimensions:19 x 13.3 x 7.9 inches
- Laptop Compatibility:Up to 17 inches
- Storage Volume:34 liters
- Weight:1.93 lbs (0.99 kg)
- Material:Water-resistant Oxford
- Pockets:34 pockets, 4 compartments
- Security:Anti-theft pocket
Our verdict“The pick for organized over-packers — maximum pockets and capacity with laptop protection, as long as you supply your own power bank.”
YALUNDISI Vintage Backpack with USB Charging Port
Most charging-port backpacks look like tactical gear; YALUNDISI leans vintage, making it the style-forward choice for college students who care how the bag reads on campus. The luggage strap is a genuinely useful travel feature that FENGDONG lacks — slip it over a suitcase handle and roll through the airport hands-free. Nylon construction keeps it lightweight, and the bottle holder is a campus-friendly touch.
The cap is the laptop sleeve: 15.6 inches maximum, well below the 17.3-inch capacity of FENGDONG, BANGE, and Goloni. Compared with the LOVEVOOK, which fits up to 17-inch machines with 34 liters of space, YALUNDISI trades capacity for character. Five pockets also mean less granular organization than the organization leaders here. Style-conscious students with standard laptops win; gamers with big rigs should look elsewhere.
Pros:- Distinctive vintage styling that stands out from tactical-looking rivals
- Luggage strap simplifies airport and train travel
- Lightweight nylon build comfortable for all-day campus wear
- Bottle holder and 5 pockets cover daily student essentials
Cons:- Laptop sleeve limited to 15.6 inches — smallest capacity in this lineup
- Fewer pockets than the LOVEVOOK or BANGE
- Power bank not included
Best for: College students and style-conscious commuters with laptops 15.6 inches or smaller who want a vintage look plus travel-friendly features
Not ideal for: Owners of 17-inch gaming or workstation laptops — the 15.6-inch sleeve simply won’t fit them
- Laptop Compatibility:Up to 15.6 inches
- Material:Nylon
- Weight:Lightweight
- Water Resistance:Water resistant
- Pockets:5
- Additional Features:USB port, trolley sleeve, bottle holder
Our verdict“Choose this for looks and light travel convenience with a standard laptop — skip it if your machine exceeds 15.6 inches or you need heavy-duty organization.”
NUBILY 17.3 Inch Waterproof Laptop Backpack with USB Charging Port
Most backpacks with charging ports top out at 15.6 or 17 inches, but the NUBILY goes all the way to 17.3 inches, which matters if you own a gaming laptop or a chunky mobile workstation. The 45L capacity and 22 pockets make it the roomiest option in this lineup — noticeably larger than the Swissdigital SD803-02’s 31L — so it doubles as a weekend travel bag rather than just a commuter pack. The waterproof polyester shell is a step up in weather protection compared with the water-resistant WENIG, and the dedicated anti-theft pocket plus luggage sleeve round out a genuinely travel-ready design. The tradeoff is bulk: this is a big bag, and at 1 kg empty it carries heavier than slimmer picks. You also need to supply your own power bank.
Pros:- Fits laptops up to 17.3 inches, larger than most charging-port backpacks
- Truly waterproof fabric rather than just water-resistant
- 22 pockets and 45L capacity rival a carry-on suitcase
- Luggage sleeve and breathable back panel make long travel days easier
Cons:- Power bank not included, so charging isn’t plug-and-play out of the box
- May not fit oversized or irregularly shaped 17.3-inch gaming laptops
- Hand wash only makes maintenance fiddly for a bag this large
Best for: Owners of 17-17.3 inch gaming or workstation laptops who want maximum storage for multi-day travel
Not ideal for: Minimalist commuters or anyone with a 13-14 inch laptop — the size and weight will feel like overkill for daily use
- Laptop Size Compatibility:Up to 17.3 inches
- Capacity:45 L
- Dimensions:14.1 x 8.3 x 18.5 inches
- Material:Waterproof polyester fabric
- Pockets:22 pockets across 3 compartments
- Weight:1 kg
- Water Resistance Level:Waterproof
- Extras:USB charging port, anti-theft pocket, luggage sleeve
Our verdict“If you carry a big-screen laptop and need one bag to cover travel and work, this is the capacity champion of the roundup — just don’t buy it expecting a slim commuter profile.”
Swissdigital Design Travel Backpack SD803-02 with USB Charging Port
The Swissdigital SD803-02 is the only bag in this lineup with a USB-C charging port rather than the older USB-A standard most competitors use — a real convenience if your phone charges over USB-C. It also stands alone in offering RFID-blocking protection, which the WENIG’s combination lock and the NUBILY’s hidden pocket don’t address; frequent flyers carrying multiple cards will appreciate the difference. With 26 pockets across 7 compartments, organization is its strongest suit, though the 31L capacity means less raw hauling room than the NUBILY. The ventilated back panel helps on long walking days. On the downside, it’s nearly as heavy as the larger NUBILY despite holding less, and the black/grey-only color palette feels conservative compared with the FENGDONG’s purple option.
Pros:- USB-C charging port is more future-proof than the USB-A ports on rival bags
- RFID-blocking pocket protects cards and passports from skimming
- 26 pockets across 7 compartments offer excellent organization
- Breathable ventilation system reduces fatigue during long travel days
Cons:- Heavy for its 31L capacity — nearly 1 kg empty
- Hand wash only and limited to two color options
- Caps out at 15.6-inch laptops, smaller than the NUBILY or BANGE
Best for: Business travelers who want modern USB-C charging and RFID protection for passports and credit cards
Not ideal for: Minimalist packers or students on a budget — it costs more and weighs more than simpler options while holding less than the NUBILY
- Capacity:31 L
- Compatible Device Size:Maximum 15.6 inches
- Material:Nylon (shell and lining)
- Dimensions:6.25 x 12.25 x 19.25 inches
- Pockets:26 pockets across 7 compartments
- Weight:0.98 kg
- Water Resistance Level:Water repellent
- Extras:USB-C charging port, RFID protection, luggage strap
Our verdict“This pick makes the most sense for frequent flyers who value data security and modern charging over raw capacity.”
WENIG Anti-Theft Travel Laptop Backpack with USB Charging Port and Lock
Where the NUBILY prioritizes volume and the Swissdigital prioritizes features, the WENIG bets on security in a slim profile. It’s the only bag here with an actual combination lock securing the main zippers, plus a hidden back pocket — a stronger anti-theft setup than the WENIG alternatives that rely on concealed compartments alone. At 5.5 inches deep, it sits noticeably flatter than the NUBILY, making it a better fit for crowded trains and daily commutes than for weekend trips. The USB port and headphone pass-through cover the charging basics, and the Oxford cloth shell handles rain splashes well even if it isn’t fully waterproof. Its limits are clear: 15.6-inch laptop cap, only 14 pockets versus the Swissdigital’s 26, and no included power bank. For city commuters, those tradeoffs are easy to accept.
Pros:- Physical combination lock on the zippers offers stronger theft deterrence than hidden pockets alone
- Slim 5.5-inch profile fits comfortably in crowded commutes
- Both USB charging port and headphone access included
- Water-resistant Oxford cloth construction with a luggage strap
Cons:- Limited to laptops up to 15.6 inches
- Only 14 pockets — far less organization than the Swissdigital or NUBILY
- Power bank not included and hand wash only
Best for: Urban commuters and students who want locked-down security and a slim profile for crowded transit
Not ideal for: Travelers needing to pack clothes or gear for overnight trips — the slim 5.5-inch depth and 14 pockets won’t cut it
- Laptop Size Compatibility:Up to 15.6 inches
- Dimensions:17.7 x 11.8 x 5.5 inches
- Material:Oxford cloth, polyester
- Pockets:14
- Water Resistance Level:Water resistant
- Extras:Anti-theft lock, hidden pocket, USB charging port, headphone port, luggage strap
Our verdict“Compared with the roomier options in this lineup, this model is better suited to daily commuters who value lockable security over packing capacity.”
How We Picked
My ranking centers on how well each bag earns its charging port rather than raw spec counts. I evaluated the port placement and cable routing (a port buried behind a zipper flap is nearly useless), then weighed laptop compartment padding and true water resistance, since a charging cable does no good if rain or a dropped bag kills the laptop first. Anti-theft claims were checked against actual design — hidden zippers and combination locks scored higher than marketing labels.
From there, I scored each bag on capacity-to-weight ratio, carry comfort, and organizational layout, because these bags live on your shoulders five days a week. Travel-specific extras like TSA lay-flat openings and luggage pass-throughs separated the premium tier from commute-only budget picks. Finally, price factored in as value: a $30 bag with a flimsy cable and thin straps was penalized more harshly than a pricier bag with durable hardware, since these packs get zipped and unzipped thousands of times a year.

Factors to Consider When Choosing Laptop Backpacks With Charging Ports
A charging port sounds like a small feature, but it changes how you pack, charge, and carry a backpack every single day. Before picking one of the eight bags above, here are the bigger factors that tend to trip buyers up.The Power Bank Is Never Included
The single most common mistake in this category is assuming the backpack charges itself. Every bag on this list — and nearly every bag on the market — ships with only a pass-through USB cable sewn into the strap or lining. You must buy and carry your own power bank, which adds roughly $20–$40 and about half a pound to your real setup. Budget accordingly: a $28 backpack is really a $55–$70 charging solution. Also check the cable quality, because a frayed internal cable means dismantling the lining to replace it, and most manufacturers don’t sell spares. If you already own a slim power bank, measure it — bags with small dedicated battery pockets won’t fit chunky 26,800mAh units.
Water Resistance Ratings Are Mostly Marketing
Nearly every bag here claims to be waterproof or water-resistant, but the reality is that almost all use polyester with a PU coating, which handles drizzle and splashes but not a downpour. True waterproofing requires welded seams and roll-top closures, which none of these commuter-style bags have. What actually matters more is zipper coverage: water pools in zipper tracks and seeps into laptop compartments even when the fabric repels rain. Bags with storm flaps over the zippers (a feature the NUBILY and BANGE do well) protect electronics far better than exposed metal teeth. If you walk long distances in wet climates, a rain cover is a smarter $10 add-on than trusting any of these labels.
Anti-Theft Features: Real Design vs. Labels
The gap between claimed and actual anti-theft protection is wide in this category. Genuine anti-theft design means hidden zippers that sit flat against your back, lockable zipper pulls, and cut-resistant straps — features found on the BANGE, NUBILY, and WENIG. Other bags simply tuck the USB port behind fabric and call themselves anti-theft, which deters nothing. Think honestly about your threat model: crowded trains and tourist areas demand hidden-pocket design, while a car commute makes these features dead weight. One overlooked point — a visible charging cable hanging from your strap signals ‘expensive electronics inside’ to pickpockets, so bags with detachable or recessed ports have a genuine security edge.
Size: Bigger Is Not Better
The 17.3-inch bags in this lineup hold a surprising amount, and that’s exactly the problem — large bags invite overpacking, which strains cheap zippers and thin shoulder straps. If your laptop is 15.6 inches or smaller, buying a 17.3-inch bag wastes capacity and adds bulk against your back on crowded transit. Match the compartment to your actual device with about half an inch of slack, and remember a snug laptop sleeve protects better than a cavernous one because the machine can’t shift. Frequent flyers should also verify carry-on dimensions, since some extra-tall 17.3-inch models brush against airline sizer limits when fully packed.
Comfort Hardware Determines Longevity
Charging ports get the headlines, but strap padding and back-panel ventilation decide whether you still like the bag in six months. Look for contoured shoulder straps with dense foam, a sternum strap for heavier loads, and a breathable mesh back panel — features where the Swissdigital clearly outspends the sub-$35 options. Zipper quality matters just as much: YKK-style metal zippers survive years of daily use, while generic plastic zippers are the most common failure point on budget charging backpacks. Check the stitching around the USB port exit specifically, because that’s where cable tension concentrates and cheap seams tear first. A bag that fails at the seams makes its charging feature permanently useless.
Frequently Asked Questions
Do these backpacks come with a power bank or a charger?
No, and this surprises a lot of buyers. Every bag in this roundup ships with only an internal USB cable that runs from a pocket to an exterior port — you supply the power bank yourself. This is standard across the entire category, not a corner cut by these specific brands. Plan on adding a slim 10,000mAh battery to your budget, and confirm it fits the bag’s battery pocket before ordering. Also note that you can’t charge a laptop through these ports; they pass standard USB power to phones, tablets, and earbuds only.
Is it safe to charge my phone through a backpack USB port in the rain?
The ports themselves are low-risk because they’re only delivering 5V USB power from a power bank, not mains electricity. The bigger concern is water reaching your power bank or phone through soaked zippers and seams. On the bags here, the USB port sits on the exterior while the battery stays in an interior pocket, so light rain is generally fine — but unplug during heavy downpours. If you live in a rainy climate, the NUBILY and BANGE handle wet conditions best thanks to tighter zipper coverage. As a habit, store the cable end tucked into a pocket rather than dangling when not in use.
Can I replace the built-in USB cable if it breaks?
Usually not easily, and this is the hidden weakness of the whole category. The cables are typically sewn into the lining, so replacement means unpicking stitching and rerouting a new cable yourself — a feasible DIY fix but not something most people want to attempt. Some models, including the Swissdigital, use detachable internal cables that swap out in seconds, which is worth paying extra for if you plan to keep the bag for years. Otherwise, treat the cable gently: avoid yanking the connector and don’t leave the power bank hanging by the cable. Cable failure is the number-one reason charging backpacks get retired early.
Are anti-theft charging backpacks actually worth it for daily commuting?
It depends on how you travel. If you ride packed trains or walk through crowded areas, hidden zippers and back-panel pockets genuinely stop casual pickpocketing, and the BANGE and WENIG implement these features well. If you drive to work or mostly stay in low-density areas, anti-theft engineering adds weight and makes your own pockets harder to reach — a real daily annoyance. The charging port itself is a mild security negative, since a visible cable advertises electronics inside, so look for recessed or hidden ports. Match the security level to your actual commute rather than paying for paranoia.
Will a 17.3-inch charging backpack fit under an airplane seat?
Mostly yes, but it’s tight and depends on how fully you pack it. The NUBILY’s TSA lay-flat design is explicitly sized for carry-on rules and fits under-seat limits when not overstuffed, while boxier 17.3-inch models like the Goloni can bulge past the typical personal-item dimensions when crammed full. The safer approach is keeping the bag at 80% capacity on flight days, which also makes the laptop slide out faster at security. If you fly monthly or more, the TSA-friendly opening on the NUBILY or Swissdigital saves real time at checkpoints compared to pulling your laptop out completely. Occasional flyers can safely choose any bag here and simply pack lighter on travel days.
Conclusion
The right choice here comes down to what you carry and where. For most buyers, the NUBILY 17.3 Inch Waterproof Backpack is the best overall pick — it balances TSA-friendly travel design, genuine anti-theft features, and a well-placed charging port at a price that undercuts the premium tier. If budget rules, the FENGDONG Waterproof Backpack is the best value: it does the charging basics competently for around $30, provided you accept thinner padding and no real security features. On the premium end, the Swissdigital SD803-02 justifies its price with superior comfort hardware and a detachable cable that outlasts the sewn-in competition — the right call for daily heavy carriers and frequent flyers.
For specific needs: the WENIG is best for minimalists who carry a 15.6-inch laptop and little else, thanks to its slim profile and lock; the LOVEVOOK and YALUNDISI suit style-conscious buyers, with the YALUNDISI winning on looks and the LOVEVOOK on organization for women’s work commutes; and the BANGE is the security pick for anyone navigating crowded transit daily. The Goloni lands in the middle — a solid large-capacity commuter, but outshined by the NUBILY at a similar price. Whatever you choose, remember to budget for the power bank, because none of these bags charge anything out of the box.
