20,000Mah Battery

This huge battery, which will last you 7-13 hours, is ideal for camping or hiking with our heated Hoodies & Jumpers.

It's the biggest battery we do and will happily keep you warm and run your phone all day or night.

It can also run other USB accessories such as torches, lights, fans and even charge your laptop. It's approved for use on aeroplanes, too.

It is a high quality high output battery - don't worry, we took one apart and tested the components, as there are so many fake batteries for sale online. This one is genuine, and we personally know an employee of the company who makes them.

It's the best you can buy and comes with the full UK warranty.
