Pros and cons

Pros

Its listed 200 g weight and small dimensions suit carrying in a bag or pocket.
The 45W output claim is aimed at faster top-ups than lower-wattage banks, with compatible devices and charging setup.
Customer feedback specifically praises compact size and charging speed.

Cons

A 10,000mAh capacity is a portable backup rather than an assurance of multiple full charges for every device. The listing itself estimates that usable output is lower after conversion losses.

What to know before buying

Listing details to confirm

The listing's details state 3 hours for battery charge time, while another answer gives 2.7 hours with a 15W wall charger or 2 hours with a 20W charger and says to recharge through USB-C. The feature text also describes a detachable USB-C cable, while customer-summary text mentions a built-in cable. Confirm the selected version's cable arrangement and charging time before buying. The promised 45W output and supported-device performance are manufacturer claims, not independently verified results.

People wanting a small 10,000mAh backup for a phone or other USB-C-compatible device.
Commuters and travellers prioritizing a compact power bank with a stated 45W output.
