Power banks for heated jackets and gilets
Our heated jackets and gilets run from a 5V USB power bank, which is not included with the garment. This 10,000 mAh bank has a standard USB-A socket for the garment's lead, a display that shows the charge left, and built-in cables for charging a phone.

What size power bank for a heated jacket?
Most USB heated clothing runs at 5 volts, the standard USB voltage, so any USB power bank with a USB-A socket will power it. Capacity decides how long it runs. A 10,000 mAh bank is the usual choice: it is small enough for an inside pocket and the supplier of our gilet quotes 4 to 10 hours from one, depending on the setting.
If you need heat for a whole day, carry a second charged bank rather than one huge, heavy one. Our guide how long does a heated jacket last? shows how to work out battery time from mAh and watts.
Flying with a power bank
Under UK Civil Aviation Authority guidance, power banks go in your hand luggage, never in the hold. A 10,000 mAh bank rated at 3.7 V holds 37 Wh, well below the 100 Wh limit above which airlines need to give approval.
Charging
Charge the bank through its USB-C input. Do not leave it charging under a pillow or on a bed, and keep it away from heaters and direct sun.

Frequently asked questions
Will any power bank work with a heated jacket?
Most will, as long as it has a USB-A socket and gives 5V, which every standard USB power bank does. Some very small banks switch themselves off when the current is low, which can cut the heat on the lowest setting.
How many hours does a 10,000 mAh power bank run a heated gilet?
The supplier of our heated gilet quotes 4 to 6 hours on the warm setting, 6 to 8 hours on comfort and 8 to 10 hours on energy saving. Cold weather and an older battery give less.
Can I take a 10,000 mAh power bank on a plane?
Yes, in your hand luggage. UK Civil Aviation Authority guidance says spare lithium batteries and power banks must be carried in the cabin. A 10,000 mAh bank at 3.7 V is 37 Wh, below the 100 Wh limit. Check your airline's rules before you fly.
