- Resonate RouterUPS® Gen2 | Original Router UPS for 12V WiFi Router & Modem (Supports up to 2A) (7800mAh - 95% Longer Power Backup) | Compact Mini UPS with Intelligent Charging (Upto 6 Hrs Internet)

Works fine and has a good power backup.

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.

Good Product

Yay! Works great! Still have internet during powercuts. Also very simple to set up.

Initially delivered product was faulty. Upon contacting support for warranty claim, they processed it smoothly and I received the replacement. The replacement worked, but made a very loud shrieking humming sound enough to keep you up at night. I would suggest to rather purchase Oakter Mini UPS which does a much better (& quieter) job.

Best Wi-Fi UPS, I am getting around 5+ hours of backup with my mesh node, which is rated for 12V2A. It also has a 7800mAh battery, which is rare for this price. Build quality is good, and support is great; I got a fast response from their side via phone and mail.

I'm using this product for nearly 6 months now. seamless backup during power cuts, ensuring my internet connection stays active without interruption. It’s especially useful for work-from-home, online meetings, and study sessions where a stable connection is essential. I haven’t faced any issues so far, and the backup time is consistent and reliable.

This is my second purchase for this product which means it worked well enough for me to buy this happily again. The first one lasted about 2 years before the battery became useless.

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

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
