Bought this to keep my WiFi and router running during power cuts, and it just works- hours of backup, no drops in connection.

Rare to see that these days.Great product, even better support. Would buy again!

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.

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.

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 Oakter Mini UPS is an excellent power backup solution for Wi-Fi routers and AirFiber devices. It switches to battery instantly during power cuts, so the internet stays connected without rebooting. Installation is simple (plug-and-play), and depending on your router's power consumption, it can provide around 3–4 hours of backup. The build quality is solid, and features like intelligent charging and battery protection help improve battery life. Overall, it's a reliable choice for work, online classes, gaming, and uninterrupted streaming during power outages

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 had been using the Oatker Mini UPS for my router, and it performed reliably throughout its usage.Recently, it stopped working after my warranty had already expired last year. I contacted the customer support team expecting only troubleshooting assistance, but to my surprise, they handled my case professionally and went above and beyond by providing a replacement unit.The product itself has been dependable, and the after-sales service has been equally impressive. It's reassuring to see a company that values customer satisfaction even beyond the warranty period.Overall, I'm very satisfied with both the product quality and the excellent customer support. Highly recommended.
