Anker 737 Power Bank (24000mAh 140W)

The most capable USB-C power bank in our kit, 86.4Wh of capacity and 140W of output, which is the line where a power bank stops being a phone charger and starts being a camera power source. Provides up to 28V / 5A USB-C PD, well past the 9V / 3A (27W) the Canon R5C needs over USB-C, and well past what the LUMIX S1II asks for. In a pinch it'll run the R5C indefinitely while the camera maintains its internal LP-E6P charge, we've used this on travel days when we don't want to deploy a Gold Mount build for short pickups. It'll also charge a MacBook Pro at full speed, charge two USB-C devices plus a USB-A device simultaneously, and recharge itself in under an hour off a 65W+ wall brick. Under the 100Wh FAA threshold so it travels carry-on.
