Most powerbanks just sit in your bag, waiting until you need them to recharge your mobile device. The Pisen Rechargeable Hand Warmer Power Bank 2-in-1 will be useful in more ways than one this cold winter. The 7500mAh battery has enough power to recharge a phone up to 2.8 times (iPhone 6S). But when you don’t need to recharge your phone, some of that power reserve can be used to keep your hands warm.
The Pisen is a double-sided hand warmer that uses NTC technology to heat to 122 degrees in 30 seconds and maintain that constant temperature for 3-5 hours. It has multiple protections built in to prevent over-charging, over-heating, over-discharging, over-power, over-voltage, and short-circuit protection. It’s sized to fit easily in a pocket or in the palm of an adult’s hand. The Pisen Rechargeable Hand Warmer Power Bank 2-in-1 is available in gold, pink, or silver for $25.99 at Amazon.
