Portable AC power bank

The BFKK 31200mAh 112Wh unit delivers up to 100W AC output alongside 17W USB and 18W Type-C ports. It suits professionals and travellers who need to run laptops, phones, cameras or small appliances away from wall sockets. A built-in flashlight adds utility during emergencies or low-light situations.

Capacity and typical runtimes

The 31200mAh cell stores 112Wh of energy, enough to recharge a 12" MacBook 1.8 times, an iPad Mini 4 four times, an iPhone X eight times or a Galaxy S9 five times. Simultaneous charging across AC, USB and Type-C is supported, though the 100W AC ceiling limits the size of loads you can sustain.

AC outlet constraints

The 100W maximum AC output restricts use to devices drawing less than that threshold; larger laptops, heaters or high-draw tools will not run. Cooling is handled by an internal smart system that balances temperature during operation. The pack measures 2.7 x 2.7 x 8.3 inches and weighs 2.1 lb, fitting easily in a briefcase or backpack.

Questions about this item

Will the 100W AC outlet charge my older laptop that uses a barrel connector?

The 100W AC outlet accepts standard mains plugs, so any laptop charger with a compatible plug can be used regardless of connector type.

The built-in charging indicator shows active output status when a device is drawing power from the AC outlet or USB ports.
