For carry-on luggage with USB ports, I’d choose the French Connection St. Martin as the best overall starting point for its expandable design, cup holder, and charging convenience. The Joyway 20-Inch adds a TSA lock and spinner wheels, while the aluminum-frame top-opening case stands apart with USB-C ports and a different access style. The main tradeoffs are how much usable packing space you get, whether the charging setup suits your devices, and how much weight or complexity you’re willing to carry. A USB port typically works with a power bank stored inside, so the suitcase itself does not replace a battery. Read on for the full comparison and guidance on which features matter for your trip.

Key Takeaways
- The French Connection St. Martin is the strongest all-round feature mix in the lineup, pairing USB ports with expandable packing space and a cup holder; the blue and black entries are the same model in different colors.
- Joyway is the clearest feature-led alternative for buyers who want a TSA lock alongside USB ports, expansion, and spinner wheels in one case.
- The aluminum-frame top-opening suitcase is the lineup’s distinct specialist, offering USB-C ports and top access rather than the more familiar feature combination on the French Connection and Joyway cases.
- USB-port presence alone does not settle the choice: travelers should check whether the port matches their charging cable and confirm that they must supply a compatible power bank.
- The U.S. Traveler Boren and white PC carry-on keep the comparison focused on simpler USB-equipped hard-shell choices, while LOVEVOOK is the option to weigh when expandable polycarbonate construction matters more than an advertised USB port.

More Details on Our Top Picks
French Connection St. Martin Expandable Carry-On Luggage with Cup Holder and USB Ports, Blue Depths
I’d put the Blue Depths St. Martin first for travelers who want more than a basic USB charging port: its holder combines a cup holder, USB and USB-C ports, phone holder, and hanger. That set of add-ons can keep a drink and phone accessible while you wait, though charging still requires your own power bank. Like the Black French Connection St. Martin, it has an expandable ABS shell and eight spinner wheels, but this version lists a combination lock rather than the Black model’s zipper lock. Its dimensions are carry-on sized on paper, yet expansion can make airline fit less certain. I’d choose it over the U.S. Traveler Boren for the extra organizer features, but skip it if you need water resistance or want a USB port ready to use without supplying a battery.
Pros:- Four-in-one holder combines a cup holder, USB and USB-C ports, phone holder, and hanger.
- Expandable interior offers extra packing room when needed.
- Eight spinner wheels support movement in multiple directions.
- Top and side handles offer two ways to lift the case.
Cons:- Power bank is not included, so the USB ports need a separately supplied battery.
- ABS shell is not water resistant.
- Expanding the case may make airline size compliance less predictable.
Best for: Travelers who want USB and USB-C charging access alongside a cup holder and phone stand for airport waits.
Not ideal for: Travelers who need a water-resistant case or expect the USB ports to include a power bank.
- Dimensions:15.4 x 9 x 22 inches
- Weight:3.63 kg
- Material:ABS hard shell
- Wheels:8 spinner wheels
- Expansion:Expandable
- Charging ports:USB and USB-C
- Power bank:Not included
- Lock:Combination lock
Our verdict“Choose the Blue Depths St. Martin if you want the roundup’s broadest set of built-in charging and airport-use conveniences, and can supply your own power bank.”
U.S. Traveler Boren 22-Inch Polycarbonate Hardside Carry-On Suitcase with Spinner Wheels and USB Port, Black
The U.S. Traveler Boren keeps the USB feature in a more conventional package: a polycarbonate shell, expandable capacity, and organized lined interior rather than a built-in cup holder or phone stand. Tie-down straps and a mesh zip pocket make it a better fit than the French Connection St. Martin models for travelers focused on keeping clothes and small items in place. Its USB port still depends on a separately supplied power bank, so it is not a self-contained charger. The listed 67-liter capacity is generous for a carry-on, but the dimensions and two-inch expansion deserve a check against airline limits. Product information also conflicts on whether it has four or eight wheels, making wheel count less clear than on the St. Martin.
Pros:- Polycarbonate shell offers a different hard-case material from the ABS French Connection St. Martin models.
- Two-inch expansion adds packing room for return trips or bulky items.
- Mesh zip pocket and tie-down straps help separate and secure contents.
- Puncture-resistant YKK zippers add a stated zipper-protection feature.
Cons:- USB port may require a separate power bank.
- Product information conflicts on whether the case has four or eight spinner wheels.
- Expanded dimensions may exceed some airlines’ carry-on limits.
Best for: Travelers who prioritize a polycarbonate shell, interior packing organization, and expandable capacity over extra exterior conveniences.
Not ideal for: Travelers who want a cup holder or phone stand, need a clearly specified wheel configuration, or prefer a compact carry-on footprint.
- Dimensions:22.25 x 15 x 9.5 inches
- Weight:6.5 pounds
- Material:Polycarbonate shell with aluminum handle
- Capacity:67 liters
- Expansion:2 inches
- Charging:USB port; power bank may be required
- Wheels:Spinner wheels; listed as both 4 and 8 in product information
- Interior:Mesh zip pocket and tie-down straps
Our verdict“Pick the Boren if structured interior packing and a polycarbonate shell matter more to you than the St. Martin’s cup holder and multi-function holder.”
20-Inch White PC Carry-On Luggage with USB Port
This 20-inch PC carry-on has a front flap that gives travelers quicker access to essentials than the main compartments of the U.S. Traveler Boren or the French Connection St. Martin. That layout is useful for keeping items close at hand, while the expandable shell, interior straps, and waterproof pocket support more organized packing. The USB port needs your own power bank, as it does on those other models. A three-year warranty provides a stated support period, but its listed dimensions include wheels and handles and may still be too large for airlines with strict sizers. I’d favor this over the LOVEVOOK if the front-access design and warranty matter more than a dedicated laptop compartment; the LOVEVOOK lists specific laptop and tablet fit.
Pros:- Front flap provides quick access without opening the main suitcase.
- Expansion adds up to 15% more packing space.
- Waterproof interior pocket offers a separate place for items that need protection from spills.
- Three-year warranty is specified in the product information.
Cons:- Listed dimensions may not fit the strictest airline carry-on limits.
- USB port requires a separately supplied power bank.
- No laptop or tablet compartment size is specified.
Best for: Travelers who want a front-access flap for frequently used items, an expandable hard shell, and a stated three-year warranty.
Not ideal for: Passengers flying airlines with strict carry-on sizers or buyers who want a specified laptop compartment.
- Dimensions:21.5 x 14.4 x 9.5 inches, including wheels and handles
- Weight:8.9 lb
- Material:PC hard shell
- Expansion:Adds up to 15% extra space
- Charging:Built-in USB port; power bank required
- Wheels:360-degree spinner wheels
- Lock:TSA-approved combination lock
- Warranty:3 years
Our verdict“Choose this model if fast access to packed essentials and a three-year warranty outweigh stricter airline-size concerns or a dedicated laptop sleeve.”
French Connection St. Martin Expandable Carry-On Luggage with Cup Holder and USB Ports, Black
The Black St. Martin shares the Blue Depths version’s distinctive set of travel add-ons: a cup holder, USB and USB-C ports, hanger, and phone holder. That makes it more feature-focused than the simpler USB-equipped U.S. Traveler Boren, while its expandable ABS shell and eight spinner wheels cover familiar carry-on needs. The tradeoff is that these ports need a power bank you provide, and the shell is not water resistant. Compared with the Blue Depths model, this listing specifies a zipper lock and three pockets, while Blue Depths lists a combination lock; buyers should choose by the lock detail they prefer rather than expecting a different charging setup. Its stated 22-inch height also merits an airline size check, especially when expanded.
Pros:- Holder combines USB and USB-C ports with a cup holder, hanger, and phone holder.
- Expandable design can create more packing capacity.
- Eight spinner wheels support multidirectional movement.
- Three pockets provide additional places to separate small items.
Cons:- Power bank is not included.
- ABS shell is not water resistant.
- Expansion and listed dimensions may be a concern for strict airline sizers.
Best for: Travelers who want the St. Martin’s multi-function holder and prefer a black finish with a listed zipper lock.
Not ideal for: Buyers who need water resistance, a supplied power bank, or a clearly specified combination lock.
- Dimensions:15.4 x 9 x 22 inches
- Weight:3.7 kg
- Material:ABS
- Wheels:8 spinner wheels
- Expansion:Expandable
- Charging ports:USB and USB-C
- Pockets:3
- Lock:Zipper lock
Our verdict“Choose the Black St. Martin over the Boren if the cup holder and phone stand are useful to you, and you prefer this model’s listed zipper lock.”
LOVEVOOK Expandable Polycarbonate Carry-On Luggage with Spinner Wheels
The LOVEVOOK is the strongest fit here for travelers who want charging access alongside a work-ready front pocket: it lists space for a laptop up to 15.6 inches and a tablet up to 11 inches. That makes it more specific for device carriers than the 20-Inch White PC Carry-On, whose front flap has no stated device fit. The LOVEVOOK also expands from 40 to 48 liters and includes a wet/dry organizer pocket, TSA combination lock, and four spinner wheels. Its front compartment has a real packing cost, though, since it may reduce room inside the main case. The USB port is listed, but the supplied description does not clarify whether a power bank is included, so I’d verify that detail before relying on charging during a trip.
Pros:- Front organizer pocket lists fit for laptops up to 15.6 inches and tablets up to 11 inches.
- Capacity expands from 40 to 48 liters.
- Wet/dry organizer pocket and seven pockets support separation of travel items.
- TSA combination lock and four spinner wheels are specified.
Cons:- Front laptop pocket may reduce space available inside the main compartment.
- Expanded dimensions may exceed some airlines’ carry-on limits.
- The product information does not state whether a power bank is included.
Best for: Work travelers who want a front organizer pocket sized for a laptop and tablet, plus expandable packing space.
Not ideal for: Travelers who need maximum interior packing room, strict assurance of airline fit when expanded, or confirmed power-bank arrangements.
- Dimensions:22 x 14.5 x 9.4 inches
- Capacity:40 liters; expands to 48 liters
- Material:Polycarbonate
- Charging:USB port
- Laptop compartment:Fits devices up to 15.6 inches
- Tablet capacity:Fits devices up to 11 inches
- Wheels:Four spinner wheels
- Lock:TSA combination lock
- Pockets:7
Our verdict“Pick the LOVEVOOK if carrying a laptop and tablet in an accessible front compartment is more important than maximizing the case’s main packing space.”
Joyway 20-Inch Expandable Hardside Carry-On Luggage with Cup Holder, USB Ports, TSA Lock, and Spinner Wheels
The Joyway makes the most sense for travelers who want USB and USB-C charging alongside a little flexibility in how much they pack. Its 20% expansion can help accommodate a fuller return trip, while mesh pockets and cross straps keep smaller items from shifting. Compared with the 46-liter framed carry-on in this roundup, the Joyway lists a smaller 39-liter capacity, but its expansion and 8-pound weight offer a different balance of flexibility and portability. Four dual spinner wheels and a TSA combination lock cover useful travel basics; the cup holder is a bonus rather than a reason to choose it. The tradeoffs are practical: you must supply the power bank, and the ABS shell is not water resistant, so wet-weather protection needs extra care.
Pros:- 20% expansion adds packing flexibility for a return trip
- USB and USB-C ports support more than one common charging connection
- Mesh pockets and cross straps help keep belongings organized
- Four dual spinner wheels swivel 360 degrees
Cons:- Power bank is not included, so the ports need a separate power source
- Not water resistant
- Listed capacity is 39 liters, below the 46 liters specified for the framed carry-on in this roundup
Best for: Travelers who want an expandable, organized carry-on with USB-A and USB-C ports and can bring their own power bank
Not ideal for: Travelers who need built-in water resistance or want a charging setup that includes its own power bank
- Size:20-inch carry-on
- Dimensions:13.8 × 7.9 × 21.6 inches
- Capacity:39 liters
- Weight:8 pounds
- Material:ABS hard shell
- Expansion:20%
- Wheels:4 dual spinner wheels with 360-degree swivel
- Charging ports:USB and USB-C; power bank not included
- Lock and water resistance:TSA combination lock; not water resistant
Our verdict“Choose the Joyway if expandable packing and organized storage matter more to you than water resistance or the largest listed capacity.”
20-Inch Carry-On Suitcase with Aluminum Frame, Top Opening, Cup Holder, USB-C Ports, and Spinner Wheels
This carry-on is the access-first choice in this pair: its front-opening laptop compartment lets you reach a computer or tablet without unpacking the main section. The listing also specifies USB and USB-C ports, a phone holder, cup holder, and eight spinner wheels, giving it a more feature-packed setup than the expandable Joyway. Its stated 46-liter capacity is larger than the Joyway’s 39 liters, and the polycarbonate shell with an alloy aluminum frame is listed as water resistant. There are two notable cautions: the power bank and cable are not included, and the description gives conflicting dimensions, making fit checks less certain. Pick this for organized tech access; skip it if you need dependable sizing details or expansion for extra packing room.
Pros:- Front-opening compartment provides quick access to a laptop or tablet
- USB and USB-C ports accommodate common charging connections
- 46-liter listed capacity exceeds the Joyway’s 39 liters
- Water-resistant listing and polycarbonate shell with reinforced alloy aluminum frame
Cons:- Power bank and charging cable are not included
- Product description gives conflicting dimensions, complicating carry-on fit checks
- No expansion is specified, unlike the Joyway
Best for: Business travelers and frequent flyers who want quick access to a laptop or tablet and a larger listed capacity
Not ideal for: Travelers who need confidently verified carry-on dimensions, an included power bank, or an expandable design
- Size:20 inches
- Dimensions:14.5 × 9.7 × 22 inches; listing notes conflicting dimensions
- Capacity:46 liters
- Weight:3.75 kg
- Material:Polycarbonate shell with reinforced alloy aluminum frame
- Charging ports:USB and USB-C; power bank and cable not included
- Wheels:8 spinner wheels
- Lock:TSA combination lock
- Water resistance:Water resistant
Our verdict“Choose this model if laptop access and its larger listed capacity lead your priorities, but verify the dimensions before relying on it for strict cabin limits.”
How We Picked
I compared the seven listed carry-ons by how useful their advertised features are for an actual carry-on routine: charging access, packing flexibility, mobility, security, and access style. I gave more weight to combinations that can serve different travel needs than to a single standout feature, while noting when a product listing does not specify details that a buyer should verify, such as battery inclusion or exact dimensions.
The order reflects those differences rather than treating every suitcase as interchangeable. The French Connection St. Martin ranks first for its balanced mix of USB ports, expansion, and cup holder, with its two colors counted as separate listings but not as different designs. Joyway follows for its broad feature set, while the aluminum-frame case earns a distinct place for USB-C and top-opening access. The remaining picks are useful for shoppers who favor a simpler hard-shell setup or expandable construction, but their listed features offer fewer reasons to outrank the more feature-rich options.

Factors to Consider When Choosing Carryon Luggage With Usb Ports
A charging port can be convenient, but I wouldn’t let it decide the suitcase choice on its own. Match the case to your airline rules, packing habits, and the power bank and cables you already own; then weigh the extras against added complexity.
Check Airline Size Rules Before Comparing Capacity
A suitcase described as a carry-on may still exceed a particular airline’s cabin limits, especially when wheels and handles are included in the measurement. Check the airline’s current size and weight rules for the route you fly most, then compare them with the manufacturer’s full exterior dimensions. Expandable bags need extra care: using the expansion section can make an otherwise suitable case too deep for some limits. Don’t assume a 20-inch label settles the question, since brands may measure the shell differently. If you fly several airlines, a slightly smaller case can be more practical than maximizing space on paper.
Treat the USB Port as a Pass-Through, Not a Battery
Most suitcase USB ports connect an external power bank to an accessible port, so the battery is usually something you provide and pack inside. Before buying, check how the interior cable connects, where the battery sits, and whether it can be removed easily for charging or security screening. Match the port to your device: a USB-A port may require a different cable or adapter from USB-C, and a port label alone does not guarantee fast charging. Check the power bank’s capacity and the airline’s current rules for carrying spare lithium batteries in the cabin. If you already carry a battery in a personal item, a suitcase port may add convenience without replacing your usual charging setup.
Decide Whether Expansion Will Solve a Real Packing Problem
Expansion can help on the return trip or for bulky items, but extra room can encourage overpacking and make a carry-on harder to keep within airline limits. Think about whether your usual trips require more capacity or whether organized packing would solve the problem without expanding the shell. Also check whether the expansion zipper is easy to reach when the case is packed and whether you can still close the suitcase without strain. A fixed-capacity case may be simpler for travelers who want a consistent cabin footprint. If you choose an expandable model, plan to use that space selectively rather than treating it as guaranteed carry-on capacity.
Compare Access Styles With How You Pack
Traditional clamshell luggage opens into two sides, which can make packing familiar but requires room to lay the case open. A top-opening design may make it easier to reach items in tighter spaces, though its layout can feel less natural if you organize belongings in two halves. Consider where you’ll open the suitcase most often: a hotel room, a train aisle, or a crowded terminal changes which access pattern feels practical. Check whether the interior compartments hold small items securely when the case is upright. A novel opening style is useful only if it fits your packing routine and the space you usually have available.
Weigh Security Features Against Added Hardware
A built-in TSA-accepted lock can save you from buying and packing a separate lock, but it does not make a suitcase theft-proof. Check what kind of lock the listing specifies and how the zipper or frame closes around it. Aluminum frames can offer a different closure feel from zipper cases, but the added hardware may affect weight and how the case flexes under pressure. For a carry-on, every extra pound matters because airline cabin weight limits vary. Favor a lock or frame feature when it solves a clear concern, not just because it adds another item to the feature list.
Look Beyond the Shell Material and Feature List
Polycarbonate is common in hard-shell luggage, but the material name alone does not tell you how well a specific suitcase will handle rough treatment. Check the warranty, wheel construction, handle stability, zipper or frame design, and whether replacement parts are available. Spinner wheels can make rolling easier across smooth terminals, while uneven pavement and curbs still call for lifting and careful handling. Cup holders and charging ports add convenience but also create parts that may need more attention than a plain case. When two options seem similar, prioritize repair support and clear product specifications over extra accessories.
Frequently Asked Questions
Do carry-on suitcases with USB ports include a power bank?
Do not assume one is included. A suitcase USB port commonly acts as an extension from a power bank you place inside the case, and product listings can vary on whether a battery is supplied. Check the box contents and instructions before buying, then confirm where the battery sits and whether it can be removed easily. If you already own a power bank, check its connector and charging output against the suitcase’s port setup. Airline rules for spare lithium batteries apply to the battery, not just the suitcase.
Can I bring a USB-port carry-on on any airline?
Carry-on eligibility depends on the airline’s size and weight limits, not on whether the suitcase has a USB port. Measure the case including wheels and handles, and compare those measurements with the rules for each airline on your itinerary. An expandable case may exceed a limit when expanded, so treat that extra capacity as optional rather than guaranteed cabin space. If the suitcase uses a removable power bank, follow the airline’s battery rules as well. Checking both the case dimensions and battery policy before travel can prevent avoidable gate or security problems.
Is USB-C worth choosing over a standard USB port on luggage?
USB-C is useful if your devices and cables already use that connector, but the port label does not tell you its charging speed or power output. Check the product specifications for output details and whether the connection is powered by a suitable battery stored in the suitcase. A standard USB port may work just as well if your existing power bank and cable setup uses it. Avoid choosing a case based on connector type alone; compare it with your phone, tablet, and battery. An adapter can bridge some gaps, but it adds one more small item to keep track of.
Should I choose an expandable carry-on if I want more packing space?
Expansion makes sense if you regularly bring back souvenirs or need occasional room for bulkier items. It can also increase the case’s depth beyond an airline’s cabin allowance, so check the expanded dimensions before relying on that space. For frequent flights with strict size limits, a fixed-capacity bag may make packing choices more predictable. Consider whether you can keep your load within limits without expansion on most trips. If the answer is yes, an expandable design can be a useful reserve rather than a feature you depend on every time.
Is a built-in TSA lock enough to protect valuables in a carry-on?
A built-in TSA lock can help keep a suitcase closed and let authorized security personnel inspect it using approved procedures, but it is not a guarantee against theft. Keep passports, medication, electronics, and other essentials in a personal item that stays with you. Check the lock type and how the case closes, especially if you are comparing a zipper case with an aluminum-frame design. A lock is most useful as one part of sensible packing, not as a reason to leave valuables unattended. For trips with multiple transfers, easy access to essential items matters more than adding another lock feature.
Conclusion
I’d choose the French Connection St. Martin as the best overall for travelers who want USB ports, expansion, and a cup holder in one familiar hard-shell format; its blue and black versions serve the same role. The Joyway is my best feature-rich alternative for buyers who also want a TSA lock, while the aluminum-frame top-opening case is the best premium-style pick for travelers who specifically prefer USB-C and top access. For best value, compare the U.S. Traveler Boren and white PC carry-on against your must-have features and confirm their precise specifications before choosing. For beginners, I’d favor a straightforward hard-shell option and focus on airline fit and power-bank compatibility before extra accessories. LOVEVOOK makes the most sense for someone prioritizing expandable polycarbonate construction, while frequent USB-C users should give the top-opening model a closer look.
