The HotRox Double Sided Electronic Hand warmer with Power bank is recharged from USB, so can be charged from any existing mains USB Charger or PC. It sits comfortably in the palm of your hand and provides heat on demand, it lasts up to 6 hours, has two heat settings (45 and 50 degrees) and gives 2 full charges to your smartphone.
How it works : Simply hold the On/Off switch for 4 seconds to turn your HotRox on to its lower heat setting – if you’d like it to be hotter, press the on/off switch again briefly – and repeat when you’d like the heat reduced again. A red light flashes to let you know it’s working – slow for medium heat and fast for high – and blue lights show you it has charge… If the blue lights go out, you know it’s time to recharge your HotRox Hand Warmer.
HotRox hand warmers are great for any activity when you feel a bit nippy. So are ideal for Walking, Golf, Commuting, working outdoors, fishing, camping, cycling, watching live sport.
