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. Read more..
Lighter Than Anything You’ve Carried
With a compact body, it’s 55% smaller than standard bricks in this category. That’s serious savings in your vest, and serious freedom on the trail. No bounce. No bulk. Just clean, pocket-sized power.
Stronger Than the Trail
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.
Trail-Tested
Tested with real trail hazards — including direct impact from a sharp trekking pole.
Charge Safer With Flame-Resistant Design
Zero Power's frame is made from aerospace-grade nylon reinforced with fiberglass and an added flame retardant. It resists ignition when exposed to open flame—offering extra safety and protection for every outdoor adventure.
Chip-Driven Efficiency
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.
Designed for Emergencies
Zero Power features an auto-stop safeguard that locks in the last 10% of battery. This emergency reserve gives you up to30% phone battery—just enough for a call, a GPS fix, or emergency headlamp use.
USB-C Lanyard Cable
Doubles as a strap — to secure Zero Power to your backpack or harness, and always within reach when you need it.
More Durability Tests
Tested by Flextail Labs to withstand 40,000+ plug/unplug cycles— built for-term reliability in the wild.
They’ve also put it through comprehensive water-resistance testing—its IPX4 rating is more than enough to handle unexpected splashes and rain on the trail.
