To keep you on the water longer, the Whitewater 7.7v 5000mAh Compact Power Bank is designed to supply power to your Torque Heated Vest, along with your phone, camera, and other devices using the input/output USB-C charging port. The USB-C port is there for safely powering or charging your devices on the go. Recharge the power bank with the included USB-C to USB-C cable and the input/output USB-C port. The DC port attaches to the built in cable on your vest to operate the heating panels. When used properly, the Power Bank protects itself from surges, overcharging, overheating, and more. It is also airplane-approved, allowing you to keep your devices charged when you're on-the-go. Our new 7.7-volt Power Bank includes a smart safety feature that keeps it in "sleep mode" until activated. This helps prevent accidental power drain and ensures the battery delivers full performance when you need it. Here's how to start things up: Plug the power bank into your vest. Press the small button on the side of the power bank once to "wake it up." Then press the power button on the chest of the vest to turn it on. That's it! Once the battery is awake, your vest will heat up normally. 7.7v 5,000 mAh Battery Life: High - 2-3h hrs Med - 4-5 hrs Low - 6-7 hrs * Battery life may vary based on outside temps.
