The battery that powers your heated jackets. WHIS Coach jackets are supplied without a power source: this 10,000 mAh Power Bank is the missing piece you need to start using them.
Its capacity covers a full day of teaching on medium heat, with enough left to recharge a phone. Its two USB outputs can also power the jacket and another device simultaneously — a phone, tablet, or a WHIS set. It can be recharged via Micro USB or Type C, four indicator lights show the remaining charge, and overload protection keeps everything safe. Weighing 200 g and measuring 9 x 5.5 x 2 cm, it fits into an inside pocket without being noticeable.
