What to know before buying

Listing details to confirm

The listing is inconsistent about physical dimensions, giving both 13.2 x 6.6 x 1.7 centimetres and 14.7L x 7.2W x 2.8Th centimetres. It also describes a built-in cable in the title, but lists USB-A and USB-C connectors and does not clarify the cable arrangement. Confirm the selected version and dimensions before buying. The stated 20W output differs from the feature text's QC 22.5W and PD 20W claim, while detailed output profiles specify USB-C up to 20W and USB-A up to 22.5W. The 6-hour recharge time is a listing claim, not a guarantee for every charger or condition.

Who is it for?

A good fit for

Phone users wanting a high-capacity power bank with several output ports for travel or days away from mains power.
Buyers who value a visible battery-level display and can accommodate a listed weight of 435g.

Less suited to

Those prioritising a particularly light pocket power bank.
Buyers who need confirmed physical dimensions or clarity on exactly how the advertised built-in cable is implemented.
