Compact 10000mAh power bank with built-in cables

The charmast W1148 is a 10000mAh lithium-polymer power bank finished in pink. It integrates four output cables for USB-C, Lightning and Micro-USB devices alongside three extra ports so up to six devices can charge at once. It suits travellers and families who want every connector permanently attached.

Thermals noise and power draw in normal use

The unit stores energy at 3.7 volts and accepts recharge through a built-in USB-A cable, a Micro-USB port or a USB-C port at up to 15 watts. Recharging takes roughly 4.5 to 6 hours depending on the input used. No active cooling is present so operation stays silent.

What the bundled cables and ports actually change

Four tethered cables eliminate loose cords and guarantee the right connector is always to hand. Three additional ports add USB-C output at 5V-3A, two USB-A outputs at 5V-3A and a second USB-C input at 5V-3A. The package includes no separate wall charger or loose cables.

Questions about this item

How do I start charging the power bank using the built-in USB-A input cable?

Flip out the attached USB-A input cord, plug it into a wall charger rated at 12 watts or above, and the unit will recharge fully in about six hours.

Which parts of the W1148 might wear out first and need replacement?

The four integrated output cables — USB-C, Lightning, Micro-USB and USB-A — are permanently attached and can fray after repeated bending, so they are the most likely components to require replacement.

What limits how long the power bank can sustain charging multiple devices at once?

The 10000 mAh lithium-polymer cell at 3.7 volts stores a fixed amount of energy, so simultaneous charging of up to six devices will deplete it faster than single-device use.
