What it is and who it's for

The Techsmarter 10000mAh power bank delivers 18W USB-C PD output and Qi wireless charging with built-in suction cups that grip the back of a compatible smartphone. It suits iPhone 12 through 15 series and Samsung Galaxy S9 through S23 owners who want cable-free top-ups while continuing to use their device.

Sustained load behaviour

The 10000mAh cell supports simultaneous charging of up to three devices via wireless, USB-C PD and USB-A ports. Pass-through charging lets the bank recharge from an 18W wall adapter while it wirelessly powers a phone. An 18W PD input restores the bank in roughly four hours.

Installation and common issues

Wireless charging activates by holding the power button until the status LED turns red; a green LED confirms alignment. If the suction cups lose grip, wiping them with a damp cloth restores adhesion. The compact 4 x 3 x 0.78 in form factor fits pockets and bags for everyday carry.
