I live in a 3rd world country where our power generator implements a 5 hour a day blackout. Usually it's between 12nn to 7pm, which is peak work hours. Obviously this is a problem.
My question is, is there a backup power source that can run for 4-6 hours or so?
All I need to get up is a laptop, my internet modem and probably an electric fan (it's really warm here).
I'm thinking of something like a UPS style of source. But I don't need it to jump up when the power goes out. And I need it to last for hours not just 5-15 minutes.
I realize that the ideal thing would be to get extra laptop batteries. but the laptop model I'm using is a old one and I tried but they've been phased out according to stores. Plus that doesn't get my internet modem up.
A generator doesn't work since I'm located in a apartment style complex.
Is there such a thing, something the size of a UPS that you can just turn on for power that goes for 4-6 hours. Then recharge the unit when power is back on?
Hoping for some help.
