Questions people ask

What is the airline limit for portable chargers in carry-on luggage?

The FAA and IATA limit for lithium batteries in carry-on luggage is 100 watt-hours (Wh) without airline approval, and 100 to 160Wh with airline approval on a case-by-case basis. To calculate watt-hours: multiply mAh by the nominal voltage (3.7V for lithium-ion) and divide by 1000. A 10000mAh power bank at 3.7V equals 37Wh, well within the limit. A 20000mAh power bank equals 74Wh, also within the limit. A 27000mAh power bank at 3.7V equals approximately 100Wh, which is the maximum without approval. Power banks must be in carry-on luggage and are not allowed in checked bags. Multiple power banks are permitted per passenger as long as each is under 100Wh, though airlines have discretion to limit the total number of lithium devices carried on. The easiest way to confirm compliance is to check the Wh rating printed on the power bank label; most manufacturers include it alongside the mAh rating.

Can a power bank charge a camera on a trip?

A power bank charges most modern digital cameras and mirrorless cameras via USB-C or Micro-USB. Mirrorless cameras including Sony Alpha, Canon R series and Nikon Z series accept USB-C charging at 5W to 30W depending on the camera model; a 20W power bank provides near-full-speed charging for most mirrorless cameras. DSLR cameras from Canon and Nikon use Micro-USB for charging at 5W to 10W. Action cameras including GoPro use USB-C at up to 18W. The power bank provides in-bag charging during a hike or sightseeing session, keeping the camera battery topped between shots without requiring a wall adapter. Most mirrorless cameras accept charging while in use; the camera draws power from the power bank through the USB-C port and extends shooting time beyond a single battery charge. A 10000mAh power bank provides 4 to 6 full mirrorless camera battery charges, sufficient for a 2 to 3-day photography trip.

Should I charge my power bank before a trip?

Charging the power bank to 100 percent before a trip is the straightforward approach and is recommended when the trip departs within a few hours. Lithium-ion batteries stored at 100 percent for extended periods (weeks to months) can lose capacity over time compared to storage at 40 to 60 percent, but this effect is minimal for power banks stored at full charge for a week or two before travel. For trips departing the next day, charging the power bank overnight using the fastest compatible charger is the most practical approach. For power banks stored between trips for months at a time, storing at 50 to 60 percent and charging to full before the trip is the better long-term approach for battery longevity. Most power banks automatically stop charging input when full and do not trickle-charge like older battery types, making overnight charging from a wall adapter safe without risk of overcharging.

    Best Portable Charger: Fast Charging Power Bank Picks 2026

    Best High Capacity Power Bank: 20000mAh 60000mAh Picks 2026

    A high capacity power bank stores more energy than a standard 10000mAh model, allowing more charges per session or the ability to charge larger devices like tablets and laptops. The trade-off is that larger batteries are heavier and bulkier, and high-capacity power banks above 27000mAh (100Wh) require airline approval for carry-on.
