I bought this UPS six months ago. I used it with my computer which has an i7 processor.
The UPS was worthless it gave a maximum power backup of 45 minutes if it was fully charged. However if I played games while my computer was on UPS power the backup would be only around fifteen to twenty minutes.
As if that was not enough it stopped working last month. This product is totally worthless and I would not recommend it to anybody it is a shear wastage of your money.
