powerbank is a locally contracted chinese ups, which does work.. you can see the same casing and box by name of twister in market, same which happened to vortex brand..people just put new sticker on it and started selling...cz it works.
Most ups are not online.. Online UPS are very very specialised and epxensive and not for home use, as they are meant for data critical servers in very big chains.. they also require quality dry batteries as our wet ones would not last much with them due to the way they work..
Cyberpower is a reputable brand, but much more expensive for what thye feature.. also my main beef with them is the low powerfactor.. energy wastage at high prices..
Inverex is nearly in the same league as cyberpower'
about homage , Bro ijaz can tell better as i have had not much experience with them, and there are mixed reviews about them.. some say new 2013 models are excellent, some say previous ones were better.. problems with pc restarts..
If something takes too long to decide, then you probably dont need it, or are unsure if you need it...
BUY SOMETHING ALREADy..
