Oakter Mini UPS for 12V WiFi Router Broadband Modem | Backup Upto 4 Hours | WiFi UPS Power Backup During Power Cuts | UPS Broadband Modem | Current Surge & Deep Discharge Protection

I've been using the Oakter UPS since January 2024. It worked well for more than a year and provided reliable backup during power cuts without any issues.A few days ago, I noticed that it had stopped giving backup even though it was charging properly. I contacted Oakter support, shared the details they asked for, and after checking the issue they agreed that the unit needed to be replaced.The support team was responsive throughout the process and handled my case without unnecessary back and forth. While it's disappointing that the UPS developed a problem after about two years, I appreciate that the company stood behind its product and processed a replacement.Overall, my experience has been positive because of the after-sales support. Hopefully, the replacement unit lasts much longer.

I purchased the Oakter Mini UPS for my WiFi router on 25 August 2025. I have been using it with my JioFiber router (12V, 2.5A), and it worked well for almost a year, providing useful backup during power cuts.One thing I really like is its compact and lightweight design. It weighs around 240g, so it doesn't take up much space and is easy to install/use with the router setup.However, just before the 1-year warranty expiry, I noticed that the backup time had drastically reduced to only around 10–20 minutes. I contacted Oakter regarding the issue, and this is where I had a very good experience.They provided a replacement unit completely free of cost. I didn't even have to return the old UPS. They only asked me to cut the wire of the old unit and send them a photo for verification. There were no additional charges or complicated replacement process.The reduced battery backup before the warranty expiry was obviously disappointing, but I appreciate that Oakter honoured the warranty and provided a hassle-free replacement.Overall, the product worked well for nearly a year, is compact and lightweight, and my experience with Oakter's after-sales/warranty support has been excellent. For me, the warranty service is a major positive point.

I have purchased this Mini UPS twice and overall, I am very satisfied with the product. It provides reliable backup for my WiFi router during power cuts and works exactly as advertised. The compact design, easy installation, and stable performance make it a great value-for-money solution.One of the two units I purchased stopped working after about 4 months. However, I was pleasantly surprised by the company's customer service. After I raised a complaint, the support team promptly approved the replacement, and I received a new UPS within just 2 days. The replacement process was handled professionally and efficiently.The only area that needs improvement is the complaint registration process. Raising a service request was somewhat cumbersome and took longer than expected. A more streamlined and user-friendly support process would make the overall experience even better.That said, the company's willingness to honor the warranty and provide a quick replacement gives me confidence in both the product and the brand. Based on my experience, I would definitely recommend this UPS to anyone looking for a reliable backup solution for their WiFi router.

I've been using the Oacter Mini UPS for my broadband router for the past year, and my experience has been excellent. It consistently provides 4–6 hours of backup, which is more than enough during power cuts. The performance has been reliable, and it has kept my internet connection running without interruption.Recently, the unit stopped working. Since it was still under warranty, I contacted customer support. They responded promptly and replaced the unit without any hassle. I was genuinely impressed with how smooth and professional the warranty process was.A good product becomes even better when it's backed by great after-sales service, and Octer has delivered on both. I highly recommend this Mini UPS to anyone looking for a reliable backup solution for their broadband router.

Writing this review after exactly 1 year of usage. At start it gave 3 hrs of back up approximately. Later in 6 months it downgrade to 2 hrs till month of 8-10. After exactly 1 year it does not work for 15 mins now. So after one year you cannot claim the warranty and this is useless now.

The Build and compatibility are good, am using it for airtel router and no issues with the product as long as it worked. However, battery backup reduced to 25 minutes or so within 8 months. Nice thing is that I have reached out to the brand they were able to provide a replacement under the warranty period. Apart from that, everything is top notch and the product is reliable and value for money as well. It's a simple plug and play setup.
