The lithium battery Li-ion 5.2A provides the necessary energy for all Keis products intended for dual-power technology (vests, gloves and shoe insoles). With a capacity of 5.2A and the integrated USB port, the battery can also be used as a power bank. For example for charging your smartphone. Due to the compact design and a low weight of 360g, the battery can be conveniently stowed in the pocket provided on the inside of the vest.

Various factors, such as the outside temperature and the individually adjustable heating intensity, have an impact on the battery life (3 to 9 hours).

You can check the charging status by shaking the battery and the diodes will light up.

The battery is supplied with a charging cable for the 110/220V socket. An additional charging cable for the cigarette lighter is available separately.
