RouterUPS® Pro (100% Extra Backup)| 10400mAh Mini UPS Power Backup for 12V WiFi Router & Modem (Supports upto 3A) | Upto 8 Hours with Multi-LED Indicator| Jio Fiber, Airtel Xstream Compatible

It's quit useful for home, office as I bought this for my home in nepal cause of electricity is not stable 🙃, but since I am using this, very nice.

Working good with Wi-Fi router

Warranty and after sale are very bad !

An excellent mini UPS for long-standing power backup. Function switches and indicators are user friendly. Absolutely no delay in switching with battery mode when power fails. Compatible with most of the routers. The features include, compact size, easy to install and value for money!

Works fine and has a good power backup.

Very bad product plus it came without its cables not as shown on the website.

I'm actually using it with my wireless CCTV for the past few days and its fast switching capability (from battery to line and vice versa) is just remarkable. It just does its job quite well. Today I got around 9 hours of backup during an electricity outtage because of a severe rainshower in my hometown. I'm a happy customer as of now. I will update the review after 6 months of use. Update (May 2024) - It's still provides uninterrupted backup for longer periods, just like before. Overall, it's a great purchase for gadgets such as CCTVs and routers. I will update this review again in another 6 months.

Edit - Upgrading to 5 star due to great service response by Resonate, and since now I have used the device for some days. On writing to Resonate about the problem, they contacted me and sent a replacement device - on testing with new product, I realized the original output cable was defective (UPS to router). This is a wonderful product, specially for places where power oscillates between Utility and backup multiple times during the day. Each time I used to face a break in wifi with a minute or two to reconnect, which is very annoying. So works great for me with no more breaks in wifi. I cannot comment on longevity of backup (need only for couple of mins each time till backup kicks in) or the device (have used it less than a week), but it is simple to install and use; and if you can't get it to work, the folks at Resonate are willing to help out. ---- My older review is below --- Did not work with my DLink DSL2750U, though it is written on product specs in Amazon. Joined all wires as per instructions, switched on the ups, but router lights won't turn on - no matter whether mains is on or not. Some other reviews seemed to suggest it works with DSL2750U, so had bought it based on that, but not sure now. I guess people have to try it themselves and see if it works for them... kind of hit and trial. Have tried to contact Resonate on the mail id they have mentioned in other reviews thinking they might respond, but still waiting for a response. I guess the ability to return the product does take away the risk out of the transaction... but disappointed all the same as I needed this kind of product due to the poor electricity situation, that causes wifi signal out multiple times a day whenever power switches to backup.
