What to know before buying
Listing details to confirm
The listing is inconsistent about the number of built-in cables: the title and special-feature text say four, while the detailed feature copy specifies three charging leads plus a built-in USB-A cable. It also describes six outputs despite a separate port-count field of four, and the stated USB-A cable recharges the bank. The claimed two full charges applies only to named older phone models. Package accessories are also not consistent between the explicit contents list and a separate kit claim. Confirm the selected listing details before purchase.
