Best Portable Charger for Travel (2026)
Travel power banks need to pass one constraint most people overlook: airline regulations. The FAA limits power banks to 100Wh (about 27,000mAh at 3.7V) in carry-on luggage. Banks over 100Wh can't fly in carry-on at all. Here's what to buy for domestic vs. international travel and different device needs.
Our Top Picks at a Glance
Anker 523 Power Bank 10000mAh
$25Zendure SuperTank Pro 26800mAh
$119Capacity vs. Airline Limits
The Anker 737 at 24000mAh is 88.8Wh — safely under the 100Wh limit for carry-on. The Zendure SuperTank Pro at 26800mAh is 99.18Wh — also legal but cutting it close for international carriers that have stricter enforcement. Banks marketed as 30000mAh often exceed the limit; always check Wh, not mAh.
USB-C PD for Laptop Charging
A standard USB-A power bank can't charge a laptop — you need USB-C Power Delivery output of at least 45W. The Anker 737 outputs 140W via USB-C, which charges a MacBook Pro at full speed. The 10000mAh Anker 523 outputs 30W — enough for phones and tablets but too slow for most laptops.
Weight Trade-Off for Packing
The Anker 737 at 24000mAh weighs 567g (1.25 lbs). For a single day trip or one-night stay, the 10000mAh Anker 523 at 194g is the smarter carry. Match capacity to your trip length: 10000mAh for 1-2 days, 20000mAh+ for 3-5 days without outlet access.
