Portable Power Bank with Built-In Cables

The Charmast CB01 is a 10000mAh lithium-polymer power bank designed for travellers and commuters who carry multiple devices. It integrates USB-C, Lightning, and Micro-USB cables directly into the chassis, eliminating the need to pack separate cords. A precise digital display shows the exact remaining capacity from 0 to 100%, removing the guesswork of traditional LED indicators.

22.5W Power Delivery Fast Charging

The single specification that decides suitability is the 22.5W Power Delivery output, which can bring a compatible phone to roughly 55% charge in 30 minutes. If your daily routine demands rapid top-ups between meetings or flights, this wattage meets that need; if you only require overnight trickle charging, a lower-output unit would suffice.

Six Simultaneous Outputs for Multi-Device Users

The unit provides six total outputs via the three built-in cables and additional ports, allowing you to charge a phone, tablet, earbuds, and smartwatch all at once. It recharges itself in about 4.5 hours using a 15W or higher USB-C charger, or roughly 6 hours via Micro-USB or the built-in cable with a 10W source. Its 5.83 x 2.74 x 0.71 inch frame weighs 240 grams and complies with carry-on airline regulations. Buyers needing higher capacity for extended off-grid use or laptop charging should look elsewhere.
