70W Flat Battery

(1 review) Write a Review

Power through the coldest weather without feeling bulky under your coat.

With its lightweight design, the new ewool battery is flat-out powerful and will keep you comfortably warm in style. Unlike our competitors battery, which is 4 times thicker, wear the new ewool battery under any jackets and feel the power and warm comfort without any bulkiness.
