ZEBRONICS U735 600VA/360W Microcontroller Based UPS for Office Computers | Home PC with Auto Restart, Generator Compatible, Boost & Buck AVR, Built-in Protection, (Not for Routers)

This is a solid choice for those looking for an affordable uninterruptible power supply, particularly for powering sensitive equipment like CCTV cameras. I have been using the UPS continuously for past week. One of its standout features is its **auto-restart function**, which ensures seamless resumption of operation after a power cut, making it incredibly convenient for CCTV systems that require continuous operation. The more reputed brands like APC and V guard don't have this function which is what made me chose Zebronics. The only problem is that it immediately resumes operation on low battery when power comes back instead of waiting for an hour or so for battery to have sufficient back up resulting in it shutting off in few minutes if power goes off again. Coming to backup time, While the seller has warning that says the UPS is not meant for micro load devices like Routers, the package of UPS says otherwise, It clearly states that this UPS supports micro load. The UPS gave a backup of more than 3 hours with just wifi router connected. With my CCTV system which consist of NVR, wifi router and 6 IP cameras, It gave about 1 hour backup. Time will tell how long the battery will last but I am satisfied with the backup time. However, the product has its shortcomings. The **build quality feels a bit cheap**, with materials that don't inspire long-term durability compared to other brands in the same price range. Furthermore, Zebronics falls behind in terms of **service center availability**, which can be frustrating for users who encounter issues and need quick assistance. The other problem is the annoying loud beep this produces every 10 sec on battery mode. This is not really a Zerbonics specific problem but a universal problem among entry level UPS irrespective of brand. I have no idea why they don't give us a mute button to silence the UPS. The only way to silence is it by removing cover and disconnecting speaker but it will lead to voiding warranty Zerbonics provides 3 UPS models in this price range but the only difference between them seem to be cosmetic. . I am very satisfied with this UPS. Its a great deal especially considering its thousand rupees cheaper than APC while having Auto restart function which is ideal for Routers, CCTV or Other systems that need power 24/7

Got the Zebronics U735 UPS for my Samsung LED TV in Jun 2025. Initial days it was working fine I used to get 15mins backup when the power goes. After nearly 6 months I noticed the performance degradation with back up of 2 to 3 mins. Exactly after one year and warranty expired, now the back is 0. Poor product, recommend not to buy this product.

Purchased this in July 2025 to act as UPS for my LED TV, worked perfectly till July this year (2026) - now the battery hardly lasts a minute. The life of the battery should have been at least 3 years, but it's gone bad within a year. The size is compact, and the beeps are not noisy but spaced at 30 seconds each so not very irritating. Should have provided an option to disable the beep. Overall, good quality product but battery longevity needs improvement. Update: Purchased a Microtek MSMF 12V 7.2Ah sealed battery (INR 1200) and replaced the inbuilt one, and the UPS is working fine now. Very easy to replace the battery using YouTube videos available, so the product is maintainable.

Nice product.

Best Products, on time delivery,

Overall it was good product, the package I received was not broken, battery life is fair, design is as shown but the frustrating thing is that it detects low voltage as a power cut and starts beeping.

Good overall. But seems to be on for 10mind and some times more than one hour. Not fixed battery backup

Really a pathetic product, No battery backup after 1 year. Better to run ur computer directly with power line.
