Cuzor Mini UPS PRO 12V Router UPS up to 3A | Up to 8 Hours | 3×2900mAh | WiFi UPS Power Backup | Mini UPS for Router

I use an Airtel-branded Zyxel AOT-5221ZY router along with this product. It's a 12V 2A router. With this UPS, I can get around 5-6 hours of battery backup consistently, which is all I could ask for. It also works for any 12V <=3A powered item which uses a barrel jack. I specifically also use it to power my 3.5 inch external hard drive enclosure (which is also 12V 2A), since it's way more convenient than having to plug the enclosure to a wall socket. The power is truly uninterrupted, even when there's a lot of electricity fluctuations. The battery life still seems to be as good as new. Charging is slow, but it's a UPS that's meant to be always plugged into power, so I'm not complaining. It doesn't make any noise (like beeping) which I like, no one in the reviews mentioned it, so I'm doing it. The included barrel connector wire (to connect the UPS to the device you want to power) is short, which might bother someone, but not a big problem for me. Overall, it's an amazing value for money product! I highly recommend it.

Ordered on 31st July and got delivered on the same day. Installed within 2 min and it worked pretty well. On the same day I got the opportunity to test it as because of heavy rain there was no electricity in my area and this ups provided around 3 hours of backup, please note that I did not get an opportunity to charge it for longer time out of the box since I installed and electricity went out. So out of the box it gave me 3 hrs of backup. I am using tata play fiber, router requires 12 volt 1.5 amp. It would be better if there is provision to hang this ups to wall. Overall I am happy with the purchase. I will test the ups after it is fully charged and post review again.

Amazing product. A must purchase. I’m giving this review after using it for a year and the power backup promised is being delivered. I haven’t faced any issue with this mini UPS

Mini UPS received on 11 June 2026. After testing, it provided around 7 hours of backup for my JioFiber Wi-Fi router. So far, the performance has been satisfactory.

Been two years since I installed it and just forgot about it. No battery replacement and no issues till now. Just plug one end to the adapter and the other to the router and its good to go. It is super essential for JioFiber users like me since the router takes a long time to start up in case of a power outage and then all the smart home devices get disconnected as well. After I installed this UPS my internet connection has been on 24x7. It has a really good battery backup as well. The maximum I got once was 6 hours. There aren't any long outages here so don't know how much I'd get with frequent power cuts but for my purposes it works really well.
