Description
At just 145g (5.1 oz) and 9.9mm (0.39") thin, it’s lighter than your phone. Race-legal and vest-ready, it disappears in your pack—until you need it most. With a compact body, it’s 55% smaller than standard bricks in this category. Zero Power's frame is made from aerospace-grade nylon reinforced with fiberglass and an added flame retardant.
Zero Power uses a smart SoC chip and high-density cobalt battery to deliver more usable energy in every charge. With 95% voltage boost efficiency and up to 30% less power loss, it performs reliably even in cold, overnight treks.
Zero Power supports 22.5W Fast Charging, powering your iPhone 15 Pro to 50% in just 26 minutes. When Fast Charging is active, the indicator light turns 🟢 green, so you'll always know you're charging at maximum speed.
Need more power on longer trips? Just double-press to activate Smart Efficiency Mode — giving you up to 30% more usable energy compared to Fast Charge. That means instead of 2 full charges, your iPhone 15 Pro gets up to 2.6 charges — that’s 0.5 more than most power banks. (*Tested by Flextail Lab)
