What to know before buying

Listing details to confirm

Listing details are contradictory or unconfirmed: the title and product description state 22.5W, while the specification block gives 18W maximum total output. The listing also describes both a built-in connector and dual USB-C ports, but the details table lists one port. Battery capacity is 5,000mAh at the cell, with 2,600mAh expected at 5V/2.4A. Check the selected listing details if these distinctions affect your choice.

Who is it for?

A good fit for

USB-C phone users who want a small backup charger with a built-in plug and can support the phone while it is connected.
Buyers looking for a compact 5,000mAh-cell-capacity bank for occasional top-ups rather than high device-charge capacity.

Less suited to

People needing a high-capacity bank for repeated full charges or a stated 5,000mAh of usable output.
Users whose phone case is thicker than 4.9 mm, or who need to leave a phone unsupported while charging.

Customer feedback highlights the compact size and portability, including use in a handbag, but reports on battery life and reliability are mixed. Some customers say it charges quickly and works well, while others describe charge retention or early-failure concerns. Durability and connector fit also draw criticism, including reports of the pack coming apart, the folding piece wearing down and the USB-C plug being too short. These concerns matter for a design intended to connect directly to a phone. The listing's estimated device output is 2,600mAh, so this is better viewed as a small top-up bank than a high-capacity reserve.

Frequently asked questions

How much capacity is available to charge a device?

The listing says 5,000mAh is the cell capacity and estimates 2,600mAh delivered at 5V/2.4A because of energy loss during charging.

The connector is stated to fit cases up to 4.9 mm thick. The listing says it is not compatible with thicker cases and recommends holding both the phone and bank while charging.

What is the maximum output?
