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 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.

Great product. Works seamless and has good battery backup. Value for money. Compatible with most wifi router and very easy to install.

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 Oakter Mini UPS with my Wi-Fi router for power backup during outages, and it has performed quite well. The biggest advantage is the instant switchover—when the electricity goes out, the router stays connected without restarting, which is great for video calls, online classes, and work-from-home setups. Oakter claims up to 4 hours of backup for the standard 12V model and up to 8 hours for some higher-capacity variants, although actual backup depends on the router's power consumption.

I purchased the Oakter Mini UPS 12V for my Wi-Fi router, and it has been working really well. The backup is reliable, and it switches over seamlessly during power cuts without interrupting the internet connection. What impressed me even more was the customer service. The support team was responsive, helpful, and quick to resolve my queries after the purchase. It's great to see a company that stands behind its product. Overall, a good quality UPS with excellent after-sales support. Highly recommended.

I purchased this product in 2025, and just before the warranty period was about to expire, it stopped working after performing flawlessly for nearly 11 months. I contacted Oakter⁠ customer support through WhatsApp. Their team was responsive, patiently listened to my feedback, and promptly arranged a replacement under warranty. Based on both the product’s performance and the excellent after-sales support, I would highly recommend this product to anyone looking for a reliable solution for their router. It would definitely be one of my top choices.

Posting it 2 years after purchase. It was reliable for 1.5yr. Though the efficency kept declining but it was still working for 2 hrs. But now it does not last even 30 minutes after power goes out.

I bought this mini UPS for my Jio modem, but unfortunately, it stopped giving backup after just two weeks. However, the customer support team was supportive. They quickly arranged a replacement unit, which has been working perfectly fine for almost a month now. Overall a good backup option for your modem considering the backup time and compactness.
