Reason for selling: I bought an IPS for my home, so I don't need this anymore. I have tested it with a 400-watt load, including a computer, router, mini fan, and high-voltage phone charging. There is a cooling fan installed inside the UPS, and it has an on/off switch. You can come to my house to test it before taking it. Do not bargain, the price is fixed. 100% copper transformer, metal body, and heavy-duty industrial-grade wiring used. 2000 Taka.
