Magnetic Wireless Charging for iPhone 12/13/14

The Techsmarter TSB4200 is a 10000mAh portable battery with built-in magnets that align to the back of iPhone 12, 13 and 14 models for cable-free charging. It also provides two wired ports so you can power other devices at the same time.

Check Your Phone Model Before Ordering

Magnetic attachment and the faster wireless rate work only with the three iPhone generations listed above. Other phones can still charge through the USB-A or USB-C ports, but they will not lock in place magnetically.

Three Simultaneous Outputs and Pass-Through Charging

One wireless pad, one 18W USB-A port and one 20W USB-C PD port can all deliver power at once, and the bank recharges itself while your devices are connected. An LCD readout shows the remaining capacity.

Questions about this item

What comes in the box with the TSB4200 and do I need a separate wall charger?

The power bank includes a built-in magnetic wireless pad, an 18W USB-A port and an 18W USB-C PD port for charging up to three devices at once. A wall charger is not included, so you will need a compatible USB-C PD adapter to recharge the bank itself.

The specs list 18W USB-A and 20W USB-C PD — which port should I use for the fastest wired charge?

Use the USB-C PD port, which delivers up to 20W for the quickest wired charging on iPhone 12, 13, 14 and other USB-C devices. The USB-A port provides up to 18W for legacy cables or a second device.

The 10000mAh rating claims three phone charges — what does that look like in daily use with the magnetic pad?

The 10000mAh cell can fully recharge an iPhone 12, 13 or 14 about three times when using the USB ports. Wireless charging is less efficient, so expect roughly two full charges via the magnetic pad before the bank needs recharging.
