All-in-one 10000mAh charger

The charmast W1148 packs 10000mAh of lithium-polymer capacity into a 5.68 in x 2.63 in x .7 in frame that weighs 240 grams. Four built-in cables plus two extra USB ports let you power up to six devices without carrying separate cords. A digital LED display shows the exact charge level so you always know how much power remains.

Capacity and headroom

At 3.7 volts the pack delivers enough energy for multiple phone recharges or a tablet top-up, but it will not run high-draw laptops. Each USB-C and USB-A port supplies up to 3 amps while the integrated cables provide 2.4 amps, so simultaneous charging splits the total current across all active outputs. Replenishing the bank takes roughly 4.5 hours through the USB-C input at 15 watts or about 6 hours via the attached Micro-USB cord at 12 watts.

Single deciding spec

The defining feature is the four integrated cables — Lightning, USB-C, Micro-USB and a USB-A input cord — which eliminate the need to pack separate leads for most phones and tablets. If you already prefer your own cables or need higher single-port wattage, a bank without built-in wires may suit you better.

Questions about this item

Will the built-in Lightning cable still charge my older iPhone if I keep using it alongside this power bank?

Yes, the integrated Lightning cable delivers 5 V at 2.4 A, so it charges legacy iPhone models at their supported speed.

How can I confirm the power bank is recharging properly after I plug it in?

The digital LED display shows the exact battery percentage, letting you watch the level rise during the 4.5 to 6 hour recharge cycle.

Which cables come attached and which ones must I supply myself?

Micro-USB, USB-C, Lightning and a USB-A input cord are built in; only an A-to-C or C-to-C cable is needed if you choose the faster 15 W USB-C recharge path.
