FAQ
The following tips will help you extend the life of your batteries. When not using heated clothing for a long time, fully charge the batteries and disconnect them. During the off-season, remember to charge batteries every 3-months. This ensures they maintain an adequate charge and are ready to use in winter. Charging the battery between 20% and 80% is a good habit. Avoid constantly charging it to 100%, as it wears out batteries over time. Avoid letting the battery drain entirely, as it can be harmful in the long run. Occasionally, it's not very damaging, but frequent drainages can reduce the battery's lifespan. Note that batteries operate best at moderate temperatures, ideally between 20°C to 25°C (68°F to 77°F). Avoid extreme temperatures and keep your heated garments away from direct sunlight, hot cars, or very hot places.
All ewool batteries are TSA-friendly. Please remember that, like laptops and camera batteries, all ewool batteries are lithium-ion and must be carried in your carry-on luggage.
You can use the 18W USB-C Flat Battery to charge your phone.
Ewool batteries are specially designed to be compatible with other ewool products. If you own heating clothing from another brand, check with their seller to see if other batteries can be used with their clothing.
No. Not all ewool batteries work with all styles. However, the 22W battery works with our heated accessories including our Heated Glove Liners and Heated Sock Covers.
