Anker Prime Power Bank (26K, 300W) review

The Prime 26K is the most capable bank we compared. Anker rates it at 300W total output across three devices, with up to 140W on each USB-C port, which covers the largest laptops at full speed while a phone charges from the 22.5W USB-A port. Its standout is refill speed: using both USB-C ports, Anker says it recharges to 50% in 13 minutes and to 80% in 40 minutes, which makes a short layover useful. Anker notes the 250W figure needs two 140W chargers and 5A cables, and 150W is possible on the optional Prime charging base. A display and a Bluetooth app show real-time stats, and Anker says ActiveShield 4.0 checks temperature 120 times a second. The bank weighs 600 g and is described as flight-approved. The catch is price: at $229.99 it costs nearly twice our top pick, and it has no built-in cable.

Who it is for

Frequent flyers and remote workers who want the fastest charging and the fastest refill between flights.
