Built for outdoor use

The Techsmarter TSB9266 is a rugged, waterproof power bank designed for adventurers, campers and outdoor workers who need reliable power away from mains electricity. Its 20000 mAh capacity charges phones 5 to 7 times and tablets 1.5 times, keeping devices running through extended trips.

Sustained output across four ports

Under continuous load the unit delivers power through two 18W USB-A ports, a 30W USB-C PD port and a 15W wireless pad simultaneously. The 30W USB-C PD port maintains fast charging for current Samsung models, iPhones and tablets, while the built-in flashlight provides illumination for 120 hours on a single charge.

Simple setup with cable-free option

Charging begins automatically when a device is connected to any port or placed on the wireless pad, so no configuration is required. The rugged housing protects the internals from knocks and water exposure, and the unit is TSA compliant for carry-on luggage. Users who need more than four simultaneous outputs or higher single-port wattage will need an additional power source.

Questions about this item

Does the 30W USB-C PD port generate noticeable heat when charging a tablet continuously for several hours?

The power bank delivers up to 30W through its USB-C PD port; sustained high-output charging will produce some warmth, which is normal for this power level.

What cables must I already have to use the two 18W USB-A ports and the 30W USB-C PD port?

You need a USB-A to Lightning or USB-A to USB-C cable for the 18W ports, and a USB-C to USB-C cable that supports Power Delivery for the 30W port.

Can I charge an older phone that only accepts 5V 1A through the 18W USB-A ports without damaging it?

Yes, the 18W USB-A ports negotiate power with the connected device, so a legacy phone drawing 5W will charge safely at its own rate.
