What to know before buying

Listing details to confirm

Listing details are inconsistent about output configuration: the specifications state two ports and 2.4 Amps, while the feature text claims dual 5 V / 2.4 A output and an A+ Lithium-Ion battery, but the details list Lithium Polymer cells. The input is called Micro USB in the details and “Mirco” in the specification text. Treat the claimed charge counts and speed as estimates, and confirm the selected listing’s exact ports, input and battery details before purchase.

Who is it for?

Buyers who want a visible remaining-charge indicator and two USB outputs.

Less suited to
