What it is
The charmast W1148 is a 10000mAh lithium-polymer power bank that stores enough energy for roughly two full phone charges. Three cables are built directly into the slim 5.67 by 2.64 by 0.71 inch body, so nothing extra needs packing. Six devices can draw power at once through those cables and the additional ports. It delivers 5V 3A output for 15W charging speed.
Who it suits
Travellers and commuters who want a single pocket-sized unit that handles USB-C, Micro-USB and older iPhone connectors without carrying separate leads. Families or groups sharing one charger on a trip will appreciate the six simultaneous outputs. Buyers who need higher-wattage laptop charging or wireless charging should consider other options, as this model is limited to 15W wired output and has no wireless pad.
Deciding specification
The 10000mAh capacity at 3.7V determines how many phone recharges are possible before the bank itself needs recharging. Expect about two full cycles for a modern smartphone or 1.3 cycles for a larger flagship. If your daily carry demands more stored energy than that, a higher-capacity bank will be required.

Questions about this item
Should I choose the 10000mAh version or is there a larger capacity available?
This model is offered only in 10000mAh, which supplies roughly 2 full charges for iPhone 16 or 1.3 charges for Samsung S24, extending battery life by 2-3 days.
What does the 15W output mean when I plug in my phone?
The 5V 3A rating delivers up to 15W, so a compatible phone can reach about 50% in 30 minutes, though actual speed depends on the device's own charging limits.
How does the USB Type-C port limit charging speed in practice?
The single USB-C port handles both input and output at 5V 3A, capping recharging of the power bank and connected devices at 15W maximum.
