Techsmarter TSB7300 10000mAh 22.5W power bank with suction cups

Techsmarter TSB7300 10000mAh power bank

The Techsmarter TSB7300 is a 10000mAh portable charger designed for users who want cable-free charging while continuing to use their phone. Integrated suction cups hold a compatible smartphone against the 15W wireless pad so you can scroll, chat or game without being tethered to a wall outlet. A built-in kickstand adds a hands-free viewing angle for video calls or media. It suits commuters and travellers who value a single device that grips, props and powers their handset.

Wireless 15W and wired 22.5W output limits

The wireless pad delivers up to 15W and works only with phones that support Qi wireless charging; devices without that feature cannot use the suction-cup attachment. Wired output reaches 22.5W from the USB-A port and 20W from the USB-C PD port, but actual speed depends on the connected device's own charging protocol. Pass-through charging lets the bank recharge while it powers another device, yet the combined draw cannot exceed the bank's total output capability. TSA compliance allows carry-on air travel without special approval.

Suction-cup mounting and recharge practicalities

Press the power bank against a clean, flat phone back and the suction cups grip securely; if grip weakens, wipe the cups with a damp cloth to restore adhesion. The slim 0.35-inch profile fits pockets and small bags, though the suction area needs a smooth surface — textured cases or curved edges may prevent a firm hold. Recharging the 10000mAh cell takes about three hours with an 18W PD wall charger (not included). Three output ports let you charge multiple devices simultaneously, but total shared current is limited by the bank's maximum rating.
