At just 145g (5.1 oz) and 9.9mm (0.39") thin, it’s lighter than your phone—and even lighter than three energy gels (60g / 2.1 oz each). Race-legal and vest-ready, it disappears in your pack—until you need it most. Zero Power is built with forged carbon fiber—a premium material used in supercars and spacecraft, now brought to trail gear. Unlike aluminum, forged carbon is compression-molded from short fiber bundles, delivering exceptional strength at ultra-low weight.
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.
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)
When Smart Mode is active, the indicator light turns 🟠 orange, so you can easily tell the difference at a glance.
