“It makes a difference when the cold sets in.”

Market, patio, parking lot, the late trip home: that’s when adjustable heat really pays off.

Visual proof

Turning off the heat is not a winter strategy.

When the battery starts running low, the instinct is to lower the heat to get through the day. A spare charged in advance lets you swap and keep the setting.

It is enough for shorter trips.

20,000 mAh A fully charged backup.

Frequently asked questions

Your questions before you order.

Straight answers to the questions that often come up before ordering.

How do I know it can power my exact jacket, and not just “a” jacket?

Compatibility depends on three points, all of which can be checked before purchase: the voltage, the connection port and the model of your heated jacket or heated vest. If all three match, this external 20,000 mAh battery powers your gear. If not, it is better to know in advance: if you have even the slightest doubt, send us your model before ordering – and we will check for you.

What do I get compared to the 10,000 mAh battery?

Reserve capacity: twice the capacity of the range’s external 10,000 mAh battery, for exactly the same purpose. The 20,000 mAh battery is made for days that never end – construction site, fixed post, trip from morning to evening – without changing batteries along the way. If your outings are shorter, the 10,000 mAh battery is enough; this is the safety margin.

Non. Keep the battery dry, and never use a damaged connector on either the battery or the jacket.

What do I need to check before I connect it?
