Zeberonics UPS U725 Which India first smaller scale stack with 600 VA with an input voltage scope of 140-300 V + - 10% AC. Company provides you 1 year battery and 2 year circuit warranty with 10 days replacement Policy.
Battery : this device offer 6 hours to 90% after complete discharge as per company said but actually it give only 30 minutes back up.
Finishing isn’t great. Run of the mill China item so that I don’t recommend you to use this product.
