Manufacturer description

When the power drops, your internet doesn't have to. The TalentCell Mini UPS packs twelve lithium-ion cells into a 97.2Wh battery, rated 27000mAh at 3.7V or 8800mAh at 11.1V. That gives your router, modem or CCTV camera hours of backup during an outage. The outputs cover most low-voltage gear. You get four DC 12V ports (9-12.6V range), one DC 9V port and USB outputs, including the 18W USB-A/USB-C PD output named in the listing, for phones and small electronics. Every DC port uses the common 5.5 x 2.1mm barrel size, so LED strips, LED panels, car DVRs, speakers and 12V pumps with that…

Frequently Asked Questions

Will the TalentCell Mini UPS keep my router and modem online during a power outage?

Yes, if they run on DC power through a 5.5 x 2.1mm barrel plug. The four DC 12V ports and one DC 9V port feed them from a 97.2Wh battery, and TalentCell says it can provide hours of operation during a power failure. Runtime depends on how much power your router and modem draw together.

What is the maximum power this battery pack can deliver?

TalentCell states it cannot continuously power devices that draw more than 37W, because higher loads drain the battery quickly. Keep your combined load under 37W, which covers routers, modems, CCTV cameras and LED strips.

What connector do the DC ports use, and are cables included?

All DC input and output ports are 5.5 x 2.1mm. The box includes two 5.5 x 2.1mm male-to-male power cables. If your device uses a different input size, you need to buy a matching cord or adapter separately.

How do I recharge the TalentCell Mini UPS?

It charges through its 12.6V/2A input using the AC/DC charger in the box. Built-in over-charge and over-discharge protection guards the 12-cell lithium-ion pack.

Can it power a desktop PC or anything with a standard AC plug?

No. The unit has DC 12V, DC 9V and USB outputs only, with no AC outlet, and it is limited to 37W of continuous load. It is designed for low-power DC devices such as routers, modems, CCTV cameras, LED lights and smartphones.
