We tested 10 travel power banks for airline compliance, charge speed, and real-world capacity. Anker, Baseus, and Zendure compared for international and domestic travel.
Our Top Picks
Anker 737 Power Bank
The Anker 737 is the most capable travel power bank that fits under the 100 Wh airline carry-on limit. 140W output charges MacBook Pro and Dell XPS at full speed. The smart display showing exact wattage and remaining time is the most useful feature on a long trip.
Pros
- 140W output charges full-size laptops at rated speed
- 24,000 mAh / 86.4 Wh fits within TSA 100 Wh carry-on rule
- Smart display shows exact wattage, battery percentage, and time remaining
- Three USB-C ports enable simultaneous laptop, phone, and tablet charging
Cons
- Large and heavy at 642 grams — not a shirt-pocket travel bank
- 86.4 Wh cuts very close to the 100 Wh airline limit — verify before each trip
Baseus 65W Power Bank 20000mAh
For MacBook Air, Dell XPS 13, and Lenovo ThinkPad — laptops that charge at 45 to 65W — the Baseus delivers full-speed charging at a more portable size than the 140W tier. The 72 Wh capacity gives clear airline headroom.
Pros
- 65W USB-C output handles most ultrabook laptops
- 72 Wh capacity well within airline limits
- Much lighter than 140W options
Cons
- 65W insufficient for full-speed charging of power-hungry laptops (gaming, workstation)
- No display — cannot check remaining charge by wattage
Zendure SuperTank Pro
The SuperTank Pro maximizes capacity within the 100 Wh airline limit. Four USB-C ports let you charge multiple devices from one bank, though total output splits when all ports are active.
Pros
- 100W combined output across four USB-C ports
- 26,800 mAh / 96.48 Wh — still within airline limit
- Compact form factor relative to capacity
Cons
- Split output means each port gets less than 100W when multiple devices connected
- Heavier than capacity-equivalent Anker options
Anker 545 Power Bank 60W
For day trips or short travel where you primarily need emergency phone charging plus occasional laptop top-up, the Anker 545 provides good output at a size that fits in a jacket pocket.
Pros
- Small and light for its 60W capability
- Display shows remaining percentage
- Handles USB-C laptop charging at 60W
Cons
- Smaller capacity means fewer full phone charges
- 60W output may throttle with some laptops
Omni 20+ USB-C
The Omni 20+ includes an AC outlet on the bank itself — useful for charging devices that only have wall adapters: older camera batteries, older laptops with proprietary barrel connectors. The wireless pad also handles Qi-enabled phones.
Pros
- AC outlet on the bank for non-USB devices
- Wireless charging pad built in
- 72 Wh well within airline limits
Cons
- Heavier than USB-C only banks
- AC outlet limited to 100W for small devices only
INIU Portable Charger 20000mAh 22.5W
For travelers who only need to charge phones and tablets, the INIU delivers high capacity at low cost. The 22.5W limit means it is not appropriate for laptop charging, but for phone-focused travel it provides multiple full charges.
Pros
- Budget-friendly high-capacity bank
- USB-A and USB-C outputs for older cables
- 72 Wh within airline limits
Cons
- 22.5W output too slow for laptop charging
- No display, LED dots only
Ugreen Nexode 25000mAh
The Ugreen Nexode provides 100W output at a price point below the Anker 737. Good option for travelers who need laptop charging capability but do not need the full 140W capability of premium options.
Pros
- 100W output for full laptop charging speed
- 90 Wh within airline carry-on rules
- Four ports total (two USB-C, two USB-A)
Cons
- Heaviest option in this category at 570 grams
- 100W only available on single port; splits when multiple devices active
Anker PowerCore III Elite
The PowerCore III Elite's high capacity makes it ideal for multi-day trips away from power. The bundled charger eliminates an accessory purchase. Verify Wh against your specific airline's policy before traveling internationally.
Pros
- 26,000 mAh high capacity for multi-day trips
- 60W USB-C output
- Bundled with 60W wall charger
Cons
- 93.6 Wh cuts close to the 100 Wh airline limit
- 60W may be insufficient for some larger laptops
Jackery Explorer 240 V2
For road trips, camping, or international travel where you are checking luggage and need a true portable power station, the Jackery Explorer 240 V2 provides AC outlet capability. Cannot go in aircraft carry-on.
Pros
- Full AC outlet at 300W peak for any plug type
- USB-C and USB-A ports in addition to AC
- Solar panel compatible for outdoor charging
Cons
- 240 Wh exceeds airline carry-on limit — checked baggage or road travel only
- 3 kg weight means carry-on is impractical even if allowed
Veger Power Bank 30000mAh
Exceeds the 100 Wh airline carry-on limit. Cannot be used as aircraft carry-on. For ground travel only. Verify actual capacity against rated specs from independent reviews before trusting the rated 30,000 mAh.
Pros
- High stated capacity for price
- Multiple ports
Cons
- Actual capacity may differ significantly from rated mAh
- 108 Wh exceeds 100 Wh airline carry-on limit
Travel power bank selection involves three variables that matter more than they do for desktop use: airline carry-on compliance, output wattage for laptops, and real versus rated capacity.
The Airline Compliance Problem
The 100 Wh limit is strictly enforced at some airports and loosely enforced at others. The safest approach is to stay clearly under — choose a bank at 90 Wh or below rather than cutting close to 100 Wh.
Banks that state mAh without Wh make verification harder. The Wh is what airlines actually measure, not the mAh. A 26,800 mAh bank sounds like it might be under 100 Wh, but the math depends on battery voltage — and manufacturers are not always transparent about this.
Verify the Wh rating printed on the bank itself before purchasing for travel. If it is not printed, use the formula: mAh × V / 1,000 = Wh, where V is the stated battery voltage (typically 3.7V).
Output Wattage Matters More Than Capacity for Laptops
A power bank with 100 Wh capacity that outputs 30W will charge a laptop rated at 65W input at about half speed. The laptop charges, but slowly. If you need to work while charging, this compounds — a laptop under load may use more power than the bank delivers.
Match output wattage to laptop input requirement:
- MacBook Air 13": 30W minimum, 67W recommended
- MacBook Pro 14": 67W minimum, 96W recommended
- MacBook Pro 16": 96W minimum, 140W recommended
- Dell XPS 13: 45W minimum, 60W recommended
- Gaming laptops: 65W minimum, 100W+ recommended
Real Capacity vs. Rated Capacity
Every power bank loses some energy to heat during the conversion from battery voltage to output voltage. A bank with 100 Wh internal capacity delivers roughly 70 to 85 Wh to connected devices, depending on conversion efficiency.
This is normal and accounts for why a 26,000 mAh bank does not charge a phone 6 to 7 times even though the math suggests it should. Higher-quality banks (Anker, Baseus) have better conversion efficiency — typically 85%+. Cheaper banks may be 70% or below.
