20000mAh Portable Charger with Built-in Cables

The charmast C2065 is a 20000mAh lithium-polymer power bank designed for travellers and commuters who need multiple device charges away from wall outlets. Integrated USB-C, Lightning and Micro-USB cables eliminate the need to carry separate cords. A digital display shows the exact remaining capacity from 0 to 100 percent.

Sustained 22.5W Output Across Six Ports

The unit delivers up to 22.5W through its built-in USB-C cable and secondary USB-A ports, maintaining fast-charging rates while powering up to six devices simultaneously. Recharging the bank itself takes six hours via the built-in USB-C input or twelve hours via the built-in USB-A input, so overnight top-ups are practical.

Check Your Device Ports and Recharge Plan

Verify that your devices use USB-C, Lightning or Micro-USB connections to match the built-in cables. Ensure you have a compatible wall charger for the 5V, 9V or 12V input profiles if you want the six-hour recharge speed. The 325g weight and 6.3 by 2.85 by 0.75 inch dimensions should fit your preferred bag or pocket.

Questions about this item

How warm does the C2065 get and what is its power draw when charging devices all day?

The power bank delivers up to 22.5W total output across six ports. It uses lithium-polymer cells and has a digital percentage display so you can monitor remaining capacity during extended use.

What cables or adapters must I already own to recharge the C2065 itself?

The unit includes built-in USB-C, Lightning and Micro-USB cables for output. To recharge the power bank you can use the built-in USB-C cable with a compatible wall charger or the built-in USB-A cable with a standard USB-A source.

Will the C2065 charge an older phone that only accepts 5V 1A through its Micro-USB port?

Yes. The built-in Micro-USB cable outputs 5V at up to 2.4A, and the USB-A ports include a 5V 2.4A profile, so legacy 5V 1A devices will charge normally.
