What to know before buying

Listing details to confirm

The listing gives conflicting thickness claims: the title says 0.4 inches, a feature description says 0.43 inches or 1.1cm, and the dimensions fields say 0.47 inches. It also lists Corded Electric as the power configuration despite describing a rechargeable power bank, and the compatible-device field says only Headphone despite broader phone compatibility claims. Confirm the selected listing's details before relying on any of these entries.

Who is it for?

A good fit for

Phone users who want a pocketable backup charger with an integrated USB-C cable and wireless charging option.
MagSafe-enabled iPhone users seeking magnetic attachment, or Qi-phone users who already have a compatible magnetic case.

Less suited to

Buyers who need a firmly established thickness or verified device compatibility based only on the listing's inconsistent entries.
People who want an independently substantiated battery-longevity record, since customer feedback includes reports of early failure as well as all-day use.
