Zero Power

​​​

Carbon Fiber Shell
The body of Zero Power is crafted from forged carbon fiber, a high-performance composite material used in supercars, aircraft, and professional sporting gear. Unlike traditional woven carbon, forged carbon is pressed into random patterns under intense pressure and heat, resulting in a material that is twice as strong as plastic at a fraction of the weight.

 

 

 

 

 

 

 

 

 

 

 

 

Ultra-Compact, Ultra-Light Design
Zero Power is engineered to be thinner than a smartphone, at just 9.9 mm thick, and weighs only around 145 grams. This makes it one of the slimmest 10,000 mAh power banks on the market. Its compact footprint means it can slide into small pockets, tech pouches, and even slim wallets or passport holders. For travelers, backpackers, or EDC (Everyday Carry) users trying to minimize bulk and maximize efficiency, this is a rare combination of size and power that doesn't force compromises.

 

 

 

 

 

 

 

 

 

 

 

 

 

High-Efficiency 10,000 mAh Battery
Despite its slim design, Zero Power packs a true 10,000 mAh capacity, but what makes it unique is its internal efficiency. Flextail claims the device provides up to 30% more usable output than many other power banks with the same stated capacity. This is due to highly efficient circuitry, minimal energy loss during transfer, and power conversion that maximizes output without overheating. For users, that translates to 2 full charges for an iPhone 15 Pro, or the ability to charge smaller devices like earbuds or smartwatches multiple times without draining the bank.

 

 

 

 

 

 

 

 

Dual Charging Modes

The power bank features auto-detecting output, which intelligently switches between 22.5W Fast Charging mode for large devices like phones or tablets and a 5V/1A Smart Efficiency Mode for low-current devices such as wearables and Bluetooth earbuds. This smart switching protects small devices from overcurrent damage while still giving you the rapid charging power needed for your phone. The ability to charge both high- and low-power devices with optimal efficiency makes it more versatile than standard fixed-output banks.

USB-C + USB-A Ports

With both USB-C input/output and a USB-A output port, Zero Power works across a wide range of tech ecosystems. USB-C provides modern, fast-charging capabilities and supports two-way power (input/output), while USB-A maintains backward compatibility with older cables and devices. You can charge two devices simultaneously, such as a smartphone and wireless earbuds, making it a practical tool whether you're in a tent, on a plane, or at a café.

 

 

 

 

 

 

 

 

 

 

Built Rugged
This device is designed with outdoor reliability in mind. Its tough carbon shell is water-resistant, offering splash and light-rain protection when you're caught in the elements. It's also shock-resistant, able to withstand bumps, drops, and jostling inside a backpack or gear bag. This makes it perfect for hikers, campers, cyclists, or anyone who needs power in unpredictable environments. Combined with its slim form, it’s easy to clip to a backpack or toss into a daypack without concern.

 

 

 

 

 

 

 

 

 

Ultra-Durable Port Design
One of the standout engineering feats of the Zero Power is its extremely high port durability. According to Flextail’s lab tests, the ports have been built to withstand over 40,000 plug/unplug cycles, significantly more than typical USB ports, which usually last 5,000–10,000 cycles. This makes the device not just a short-term solution, but a power tool you can use daily for years—especially important for heavy users or field professionals who charge multiple times a day.

Low-Output Mode

A common frustration with many power banks is that they either won't charge low-current devices like smartwatches or they stop charging prematurely due to power detection issues. Zero Power solves this with a dedicated low-output trickle charging mode, ensuring a safe, steady flow of power to sensitive electronics. Whether you're topping off your Apple Watch, a fitness band, or a set of wireless earbuds, this mode ensures compatibility and prevents battery wear.
