I bought this for my CCTV NVR system (12V) too, and it handled the load efficiently for short outages. Works flawlessly on the main WiFi router. Great design, doesn’t heat up unreasonably. Ampere Cart offered the best price for this genuine Wattnine product.

Bahut hi zaroori device! Jabse yeh lagaya hai, internet ki problem khatam ho gayi. Continuous power delivery hai. Charging indicator bhi clear hai. Agar aapka router 12V ka hai to bina soche khareed lo.

The unit stopped working after about three weeks. It holds the charge, but the output voltage became unstable, causing my router to frequently restart. Tried calling customer care, and the response time was quick. Happy with the long-term reliability of the product.

Backup time is very misleading. My router only runs for about 1.5 to 2 hours, not the promised 4 hours. Plus, the power cable connectors included in the box are slightly loose for my D-Link adapter, which causes intermittent disconnections. Needs better quality control.

Build quality is good and the connectors fit perfectly. It handles my high-power router easily for about 3.5 hours, which is close to the advertised 4 hours. It gets slightly warm during charging, but nothing concerning. A solid backup solution for the price.

The product is fine, but the instruction manual was confusing regarding the cable connections. It took some trial and error to get it right. Backup time is adequate, but I wish the charging indicator was clearer. Needs better documentation.
