I want to sell my Apollo Dx ups. it is 650 va and backup time is 20 to 30 min depending on load. it gives ur computer protection for short circuit and voltage
up down. By abnormal voltage, burning down a part of ur important pc is very normal. UPS will protect for that problem.
U can check it,s backup time at my home. Now a days UPS with 20 min backup will cost u 3500 taka. But i m giving u
at 2500 taka. If u r really interested call e @01683897797
