Great performance, backup, ease of use, size and compatibility I have been using it since 3 years, moreover post warranty service is great too, i just got it repaired because the battery was not charging, it was a delightful experience and we get 1 year warranty again after the repair.

very good product. Once fully charged, device backup to 6 to 7 hours. There is no issue on connectivity and performance. Size is very compact and easy to setup any where.

Have had three of these in two different locations. Two, bought in March 2023, for a mesh setup in one apartment where power outages are rare. These are now unusable - they no longer retain charge - after having performed well when needed. And the other, bought in January 2022, hooked up to the Jio Fiber router in another house where powercuts are significantly more frequent. This one continues to work flawlessly. In both these locations, main power backup comes on in under 2 to 5 minutes typically, and only in rare cases, such as maintenance or natural calamity, main/backup power takes longer to be restored. In both locations, these have performed admirably well and as advertised. They are reliable tertiary power source for uninterrupted WiFi.Yet, the longevity of the product appears to be inversely affected by how frequently they are in 'actual' use. As described, it would appear, more frequent the power supply interruption (thus given a chance to discharge its battery) the longer they last. This may seem counter-intuitive, but I guess science often is. Unless, of course, the later batch was also of inferior quality.So, if you're in the market for this specific product (or something similar), to make them last longer, consider manually letting it discharge its battery, in case you don't get too many power cuts in your locality. Or, consider getting an equivalent product marketed under the R******e brand (I have no reason to explicitly call out another brand in this review), of which I've had one for five years now that continuous to function fuss-free in the same usage condition that rendered two of my Cuzors useless.

Good quality product! Compact and easy to setup. Using it for ACT fibernet tp-link router at home. Got around 6 hours of backup after purchase.Router power: 12V, 1A

I initially received this product without an adapter and considered returning it. However, after contacting Cuzor customer care, they guided me on how to use it properly. Since then, it’s been working perfectly without any internet interruptions. I’m very happy with this product — the price, ease of use, quality, and compact size are all great. Overall, it’s a very nice product!

Great product gives 4-5 hrs of backup power.Great customer service as well my first unit that I recieved has problem it used to get shut down for 5 min randomly on some days, I contacted customer support and they replaced it with a new unit free of charge which is working absolutely great.Compatibility:Compatible with jio routerEase of use:Very easy to setup and comes with all the necessary cables.Quality:Good quality, much recommended.

Works good for me, about 3.5 - 4 hours of backup. It's battery died once but the team sent me a new one as it was under warranty. Must have. Helps me a lot supporting my WFH and much helpful during long power outages and helps save my mobile data.

I've used Cuzor mini UPS for last 3 years. Amazing product.I loved the option to replace battery at a nominal price. And Cuzor takes care of disposing the old battery sustainably!
