10,000 mAh power bank for heated clothing

Made to run heated clothing

Our heated jackets and heated gilets come without a power bank. Their USB lead plugs into a standard USB-A socket at 5V, and this bank has one. Plug the lead in, switch the garment on and put the bank in the inside pocket.

The supplier of our 9-zone gilet quotes 4 to 6 hours on the warm setting, 6 to 8 hours on comfort and 8 to 10 hours on energy saving from a 10,000 mAh bank. The supplier of our 9-zone jacket quotes up to 8 to 12 hours. In hard frost you get less. The maths behind those numbers is in how long does a heated jacket last?.

Also charges your phone

Two cables are built into the case: one USB-C and one Lightning. They carry fast charging for phones. The display on the front shows the charge left as a number, so you know when to top it up. The bank charges through its USB-C input.

Flying with it

The cell is rated 10,000 mAh at 3.7 V, which is 37 Wh. UK Civil Aviation Authority guidance says power banks must go in your hand luggage, never in checked bags, and power banks up to 100 Wh need no airline approval. Check your airline's own rules before you fly.

Safe use

Charge the bank on a hard surface, not under a pillow or on a bed, and keep it away from heaters and direct sun. Never wash it: always take it out of a garment before washing. The maker's OKOP logo is printed on the case. Because it contains a lithium battery, it travels on a carrier service that accepts batteries.
