Guys, what can I run on a 600VA UPS ?
I want to run laptop + extra LCD monitor + hotspot + charger / power bank.
Wrong question.
More important is how long can you run it for?
At 1800 you got scammed. No free lunch in the market or in life.
2 yrs ago I bought a new Exide 12V 7AH (UPS) battery for 1100 after getting a discount from a known shop.
Today the same battery is likely 1300+. The transformer in the UPS is worth >1000 amd the PCB is worth a few 100s more.
The only way they give that price is to use an UNBRANDED local battery which dies before 1 yr with substandard performance.
Either way be ready to fork out 1300 every 16 months to buy a new battery.
