Oakter Mini UPS for 12V WiFi Router Broadband Modem | Backup Upto 4 Hours | WiFi Router UPS Power Backup During Power Cuts | UPS Broadband Modem (12 Volt Backup Upto 4 HRS)

I bought the Oakter Mini UPS in July 2023, and it has been a very useful addition to my home setup. It kept my WiFi router running smoothly during power outages, which was especially helpful during remote work and online meetings. The backup time was as advertised—around 3 to 4 hours—which is more than enough for most power cuts.The build quality is solid, the installation was straightforward, and the device worked seamlessly without any hiccups. It’s a true plug-and-play solution and perfect for anyone looking for uninterrupted internet access.Only one small issue—after about 18 months of use, I noticed the backup time has reduced significantly. However, considering the price and the convenience it provided for over a year, I still believe it’s a worthwhile purchase.Highly recommended for anyone tired of sudden internet drops during outages!

I’ve been using the Oakter Mini UPS for my WiFi router, and it’s been a great buy. Setup was super easy, and it keeps my internet running smoothly during power cuts. Backup lasts around 2–4 hours, which is perfect for my work-from-home setup. Also, their customer service is excellent—very responsive and helpful. Totally worth it!

3 star review for item.5 star review for after sales service.6 months of use later the device stopped working and giving backup.But the customer service was excellent on responding and resolving with 0 cost replacement for the item.Hope to receive the replacement soon.

I was quite excited about the product when I received it and it is nice touch and feel, good quality but was eager to see what backup time it actually gives. I was surprised a little bit and disappointed at the same time since it only gave 1 hr and 45 min backup where company claims it to give upto 4 hrs. I was atleast expecting not less than 2.5 hrs. Still giving it 3 star since atleast it gave me 1.75 hrs backup when it required.

Why did you pick this product vs others?:Product is under warranty. The back up is nil, so they arranged replacement for my order. They are quickly responding over WhatsApp which is very helpful. Thank you so much for doing needful. Things very quickly.I have purchased two of them, so one is working continuously more than one year. There is no issue at all another one.

I am using it with an Airtel Xtreme router that is 12V 1.5A that consumes little higher current than usual 1A routers that are mostly in the market. I am getting little over 2 hours of backup.On the technical side, it has 2S (2 x Li ion batteries in series) with output of 3.7V (max 4.2V) per battery. It uses DC to DC setup converter to get the constant 12V output. The season behind the compact size.On return/Warranty: After using it for about 8 months, my mini UPS stopped giving backup (the mini UPS would die as soon as AC mains is cut off and so would router due to no electricity supplied to it). I reached out to the Oakter as it was within the 12 months warranty. Their support team is very prompt on the whatsApp, they tried debugging with me while requesting me to do a couple of combinations and videos to validate the device itself is the problem. After a couple of test and videos, they promptly confirmed the battery has gone into deep discharge, and they will be send me a replacement mini router. The delivery of the replacement router was well within 3-4 days. The new one is working well as intended.Would like to make special mention of very polite and patient support experts at Oakter: Mr. Ashish & Ms. Sangeeta

I order this product 6 month ago..It was working fine. but recently this product got discharged quickly. After that I contact customer service andI appreciate customer service who provide me solution as a replacement.Thank a lot.

I have two ofthese back ups. One has worked great for over a year. The other stopped working after 7 months because the power switch melted. Customer support was very helpful though. Because the product was still under warranty, they sent a new one for free with little hassle.
