Compact 10000mAh power bank with integrated cables

The charmast W1148 is a 10000mAh lithium-polymer power bank designed for travellers who want a single device to charge multiple phones and tablets. Its white, slim profile measures 5.68 in by 2.63 in by .7 in and weighs 240 grams. Four reinforced cables are built directly into the body, removing the need to carry separate cords for daily use or trips.

Low heat and silent operation during charging

The unit operates at 5 volts with a maximum 3 amp input and output, so it stays cool and makes no audible noise while recharging phones or itself. Recharging the power bank takes roughly 4.5 hours via the USB-C input at 15 watts or about 6 hours using the attached USB-A cable at 12 watts. No fan or active cooling is present, keeping operation completely silent.

Reinforced braided cables and six-device support

Three output cables — USB-C, Micro-USB and a Lightning-compatible cable for iPhone 12 to 14 series — plus three ports (USB-C, two USB-A) allow up to six devices to charge at once. The braided cables are rated for over 10000 bends and cannot be lost. Buyers who need wireless charging or a higher single-port output for laptops will need a different solution.

Questions about this item

How do I recharge the W1148 power bank and which built-in cable should I use?

Use the built-in USB-A cable or USB-C cable to recharge the power bank, or plug a separate cable into the Micro-USB input port; the attached USB-A input accepts 5V-2A, Micro-USB input 5V-2A, and USB-C input 5V-3A.

Will the four built-in cables on the W1148 wear out and need replacement?

The reinforced braided cables are tested to withstand 10,000+ bends, so they rarely need replacing; the USB-A input cable, USB-C cable, Micro-USB cable and Lightning-compatible cable all stay attached to the unit.

What limits simultaneous charging when I connect six devices to the W1148?

Total output is shared across three built-in cables (each 5V-2.4A) and three ports (USB-C 5V-3A, two USB-A 5V-3A each), so the 10000mAh capacity and combined current draw become the limiting factor under sustained multi-device use.
