This is exactly what i was looking for. I didn't want to go for an expensive, bulky UPS as i wanted power backup only for my WiFi Router. This small black box solved all my problems, and frequent power-cuts are no longer a nightmare.

Tested it twice and its giving 3.5 hours backup.There is no switchover from power-supply to battery. Works well with my TP Link WR740N Router. Packaged well and its value for money. Go for it if you are working from home (or) having frequent power-cuts...

it is working perfect for me.I am using it from last 15 days and it is giving backup upto 3 hrs that is more than enough for me.Always check ur router volt and buy that ups of same volt. For those if it is not working properly ,better go to jyothshi....

Initial Feedback of the product: packaging is very good and product build quality is quite good. I am using this power backup for two hours now and still need to test the maximum backup it gives(2 hours for now). Even 2 hours is pretty good if you are in metro or cosmopolitan city where power cuts are not that long. I will try to update my review after using thr product for a while.

Very good product, working perfectly as expected.

Router ups is ok good

I was not fine with bulky UPS, that eats space. My requirement was only to power a Modem.
This product complemented my need.It comes with adapters to suit different variants of modems. Good one

Good product...for a remote area is very useful

Quite Satisfied with the product it's just 1 week used review...but seems to be upto the mark product

Awesome go for it been using for year , liked it

The worst product ever, it stopped working after 2 months and I got replaced but even that stopped working after 3 months
