What the power bank does

The Techsmarter TSB7700 is a 20000mAh portable charger with a 10W wireless pad, an 18W USB-A port and an 18W USB-C PD port. It uses anti-slip suction cups to hold a compatible phone in place while charging. The unit supports pass-through charging and recharges in 4 hours with an 18W PD wall charger.

Who it suits and who it does not

It suits owners of wireless-charging iPhone or Samsung models who want cable-free top-ups while using their device. It does not suit buyers whose phones lack wireless charging, users who need more than 20000mAh capacity, or anyone requiring faster than 10W wireless output.

The spec that decides fit

The single deciding specification is the 10W wireless charging pad combined with suction-cup attachment; if your phone does not support wireless charging or cannot adhere to the cups, this power bank will not work as intended.

Questions about this item

How much space do the suction cups need on the back of my phone?

The power bank measures 5 by 3 by .6 inches; the suction area must be flat and clean for the cups to grip.
