Inside the Mini UPS — 3-cell 12V lithium power pack

Look inside. Every component, engineered.

2.5 hrs
Of uninterrupted Wi-Fi

When power goes out,
your Wi-Fi doesn't.

An 11.1V 2900mAh 3-cell lithium pack kicks in automatically the moment your mains fails. Zero interruption. Your router never reboots.

Perfect for those 2-hour cuts that ruin your Zoom call, your kid's online class, or the match you're streaming.

Switchover time

Smart power detection.
Instant switchover.

The moment mains fail, battery takes over automatically — fast enough that your router doesn't even notice. No reboot, no dropped connection, no lost video call.

When mains returns, it switches back and recharges in the background. You don't do a thing.

0ms switchover — power cut but Wi-Fi stays on

Built for Indian homes & offices.

Every feature designed to solve real problems you face every day.

2900mAh Lithium

Premium lithium cells for long life — thousands of charge cycles, no memory effect.

Universal 12V Output

Works with 95% of Indian Wi-Fi routers & modems — Jio, Airtel, BSNL, TP-Link, D-Link, TENDA.

Silent. Fanless.

No buzzing, no beeping. Sit it next to your router and forget about it.

Overcharge Protected

Keep it plugged in 24/7 — smart circuit stops charging automatically when full.

Pocket-Sized

Just 101 × 60 × 33 mm. Fits behind the router, under the TV, anywhere.
