Power Bank
Anker Prime Power Bank (27,650 mAh, 250 W)
The biggest one — bought for laptop runtime, used most often for everything else.
Bought specifically because the laptop is a 15-inch gaming chassis and smaller power banks couldn't reach the wattage to keep it charging while in use. The Anker Prime 27,650 mAh / 250 W is the top end of Anker's USB-C line — three ports, full power delivery on each, enough capacity to charge a laptop multiple times and most phones a dozen.
In practice, the laptop charging is the rare case. The phone, the Pad 6, the camera batteries via USB-C, the Pocket 4, the Mic Mini case — those get the daily work, and the Prime mostly sits half-charged because most days don't drain it. Bought big because the rare case mattered; carried often because it covers everything else.
Weight is what you pay for the capacity. At nearly 600 grams it's not a casual pocket carry, and it occupies real volume in a bag. For a day in a city with a laptop and three accessories, it earns its place. For a quick walk with a phone, a smaller pack would be the better tool.
