Choosing your Power Bank according to your needs:

This open compatibility allows you to choose the power bank of your liking, in terms of brand name, size, capacity, color etc. There are multiple advantages:

  • You choose the power bank that best fits your needs. For instance, if you use your POLAR SEAL heated clothes only for short stays in the cold outside, a light and compact power bank of 5,000mAh will be ideal. On the other hand, if you need to spend a long time in a cold environment, you will prefer a larger model with a bigger capacity of up to 20,000mAh.
  • As power banks last only a couple of years, you are not tied up to a specific model.

If you set your buttons on two heating zones at a high level, your POLAR SEAL will heat you up for the following periods of time.

 5,000 mAh 
Around 4 hours autonomy
10,000 mAh
Around 8 hours autonomy
20,000 mAh
Around 14 hours autonomy

(Data subject to variation depending on the quality & age of the power bank)

If necessary, you can use the spare right pocket to store an extra power bank, thereby extending the heating time to a whole day.

Connecting the power banks:

You insert this power bank in the dedicated left pocket and connect it to the USB plug located inside the pocket. You need to remove the power bank from the pocket when you wash your POLAR SEAL.
