Mountain Hardware has two jackets – the Radiance and Refugium – that make use of the Ardica Moshi Power System to heat the jacket AND charge your electronics. The Ardica power supply is basically an array of flexible lithium ion batteries and is sold separately from the jacket. The battery array has two power outputs – one to power the two USB ports for gadgets (left and right pockets), the other connected to the integrated heating elements within the Mountain Hardware jackets (3 elements, 2 front, 1 rear).
The power pack is recharged by plugging into one of the USB outlets in the jacket and LEDs mounted in the wall unit let you know when the battery is charged. The entire battery system weighs just under 300 grams. One charge provides 3-9 hours of heat or 20 charges for your phone. The jackets start around $230 and the battery array will set you back another $150.
Just don’t forget the battery when you toss the jacket in the wash or get caught in the rain.
