When your device is full, Zero Power auto-stops charging—so no energy is wasted while you sleep.

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.

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.

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.

Tested with real trail hazards — including direct impact from a sharp trekking pole.

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.

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 to top up fast? 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)

When Smart Mode is active, the indicator light turns 🟠 orange, so you can easily tell the difference at a glance.

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.

Doubles as a strap — to secure Zero Power to your backpack or harness, and always within reach when you need it.

Tested by Flextail Labs to withstand 40,000+ plug/unplug cycles— built for-term reliability in the wild.

We’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.
