All-in-one charging

The Charmast W1148 integrates four built-in cables and six total outputs into a 10000mAh lithium-polymer pack. Three integrated output cords cover USB-C, Micro-USB and Lightning devices while three additional ports allow simultaneous charging for up to six devices. A digital LED display shows the exact remaining percentage. The slim 6.14 x 2.83 x 0.9 in profile weighs 240 grams and fits easily in a pocket or bag.

Multi-device users versus minimalists

Travellers carrying a phone, tablet and earbuds benefit from the six concurrent outputs and the three input options that let you recharge the bank via built-in cord, USB-C or Micro-USB. Buyers who only ever charge a single device and prefer a lighter power bank without attached cables should look at simpler single-port models.

10000mAh capacity

The 10000mAh rating determines how many full phone charges you can expect between recharges of the power bank itself. Recharging the unit takes roughly 4.5 hours through the USB-C input at 15 watts or about 6 hours using the attached input cord at 12 watts.

Questions about this item

Does the 10000mAh bank get hot when charging six devices at once?

The unit supplies up to 6 A total across its built-in and port outputs; sustained multi-device loads will warm the case but it has no active cooling.

What wall charger do I need to recharge the bank in 4.5 hours?

A USB-C charger rated 15 W or higher plus a separate USB-C cable will refill the pack in about 4.5 hours.

Will the attached Lightning cable charge my iPhone 8 at full speed?

The built-in Lightning cable delivers 5 V at 2.4 A, which matches the iPhone 8’s maximum wired input.
