All-in-One 10000mAh Power Bank

The charmast CM15 integrates a foldable AC wall plug, a Lightning cable and a 2-in-1 USB-C/Micro USB cable so you can recharge the bank itself or power devices without carrying separate adapters. It suits commuters and travellers who want a single unit that covers both input and output needs.

Shared 15W Output Across Four Ports

Total output is capped at 15W (5V/3A) and divided among every connected device, so charging four items at once reduces the rate each one receives. The USB-C input also accepts 5V/3A, giving a full recharge in roughly five hours, while the built-in AC plug takes about six hours.

Slim 0.72 in Profile with LED Display

At 0.72 in thick and 227 grams, the lithium-polymer pack fits in a pocket or small bag and meets the 38.5 Wh carry-on limit for air travel. The integrated cables remove the hassle of loose cords, and the LED display lets you check remaining capacity at a glance.

The 10000mAh cell provides up to 1.8 charges for iPhone 16 or 17 and 1.6 charges for Samsung Galaxy S25, rated at 38.5Wh for carry-on air travel.

How does the foldable AC wall plug recharge the power bank compared to the USB-C input?

The built-in AC plug recharges the unit in about 6 hours, while a 5V/3A USB-C charger does it in about 5 hours; both support pass-through charging so devices can charge at the same time.
