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

Bought this to keep my WiFi and router running during power cuts, and it just works- hours of backup, no drops in connection. Compact and easy to set up too. What really impressed me: it had a pin issue after the warranty ended due to damage by me and they still fixed it for free, no hassle. Rare to see that these days. Great product, even better support. Would buy again!

I have been using this product for around 9 months. Overall, it is a good product and worked as expected during most of my usage period. The battery backup was close to 3 hours when new, though I noticed that the runtime gradually reduced with age, which is fairly typical for rechargeable battery powered devices. Unfortunately, my unit stopped working after about 9 months. However, the after sales support experience was very positive. The warranty claim process was smooth and hassle free. The company verified the issue through a few video calls and promptly approved a replacement. Pros: • Good performance for daily use • Around 3 hours of backup when new • Responsive customer support • Seamless warranty replacement process Cons: • Battery backup reduces gradually over time • My unit stopped working within 9 months Overall, the product itself was decent, and the excellent warranty support helped maintain my confidence in the brand.

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 purchased the Oakter Mini UPS 12V, and I am very happy with its performance. It provides a reliable backup during power cuts and keeps my device running smoothly without interruption. What impressed me the most was Oakter's customer service. Even after my UPS stopped working and was out of warranty, their support team agreed to replace it free of charge. This level of after-sales service is rare and shows that they truly care about their customers. I highly recommend the Oakter Mini UPS 12V to anyone looking for a dependable backup solution backed by excellent customer support.

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.

I purchased the Oakter Mini UPS two years ago, and it has consistently served its purpose perfectly. The power backup duration is excellent, but the best part is the seamless, zero-lag switching—my Wi-Fi connection never disconnects when the power goes out. It's a reliable, no-nonsense device that genuinely gets the job done. If you want uninterrupted internet, this is a solid investment.

I have been using this Oakter 12V UPS for my Wi-Fi router Since Sep 2025, and it has been performing very well. During power cuts, it switches over seamlessly without interrupting my internet connection, which is especially useful for work. The installation was simple, the build quality feels good, and the backup time is satisfactory for my needs. The only issue I faced was that the POWER ON Indicator Light is not glowing after 4 months. Their Customer Service thru on-line understood and explained in detail about the issue. Otherwise the performance is good so far.Overall, it is a reliable and well-designed product that does exactly what it promises. I would definitely recommend it to anyone looking for an uninterrupted Wi-Fi connection during power outages.

I have connected to airtel airfiber which is good it is compatible with but due to high power consumption of airfiber 12v 3a It reduces the backup hours so currently it is providing backup of 3.5 hours. As it has specifications of 12V Upto 3A support I thought it should give at least 5-6 hours but its ending up to 3.5 hours of full charge.
