What can Zero Power fully charge?

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

Ultra-Lightest & Thinest Power Bank

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.

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 fibre—a premium material used in supercars and spacecraft, now brought to trail gear. Unlike aluminium, forged carbon is compression-moulded from short fibre bundles, delivering exceptional strength at ultra-low weight.

Why Zero Power is the Best?

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 fibreglass 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.

🟢22.5W Fast Charging

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.

🟠Charge Smarter, More Miles

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.

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 Safety Features

More Durability Tests

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.
