## Description

Built-in USB-C and Micro-USB cables make the charmast CB01 easier to bring along when you want backup power without packing separate charging cords. Its 10,000mAh capacity, digital battery display, and multiple outputs make it useful for keeping several everyday devices close at hand.

The display shows remaining power as a percentage, so you can see when it’s time to recharge the power bank.

## Who it’s for

The CB01 is designed for people who carry a phone and other personal devices through commutes, travel days, or time away from an outlet. Its built-in cables help reduce the number of loose accessories in a bag, while its six output ports are intended for charging multiple devices at once. The manufacturer lists compatibility with iPhone, Samsung Galaxy, Pixel, iPad, AirPods, Kindle, and most tablets. For iPhone models that use a different connector, choose a compatible charging option for that device.

At 240 g, it’s a practical fit for a purse, backpack, or car kit. The included travel pouch gives you a place to keep the charger together with your essentials.

## Benefits

The built-in cables make quick top-ups more convenient when you’re moving between home, work, and transit. Rather than relying on a single cable connection, the CB01 combines built-in leads with additional output ports, giving you more ways to connect your devices. Its 22.5W maximum output supports fast charging, and the manufacturer describes a low-current mode for devices such as AirPods, activate it by pressing and holding the power switch.

The digital display offers a clear readout of the remaining charge, which can help you decide whether to use the power bank now or recharge it before heading out. And when several devices need power, the six-output design lets you charge up to six at the same time. Need a charger for a trip with more than one device? That multi-output setup is the main distinction from a basic power bank built around a single connection.

Buyer feedback often highlights the convenience of carrying it and having multiple connectors for different devices. Reports on charging speed and how long the charge lasts are mixed, so the documented capacity and display are useful reference points for planning everyday use.
