Proton Soup said:i think 15A is a common breaker size now for wall outlet circuits. in the past, larger size fuses may have been used. few enough and large enough to be fire hazards.
wall outlets in an actual "shop" in a commercial building may be another story, though. do we have an electrician in the house?

It kept the PC alive during our regular winter brown outs and it powered the cable modem + wireless for an hour when the power went out, so I could stay on PF from my laptop.
I don't understand why they don't quote the actual amp-hours of the battery though - except it would allow a fair comparison of the products.
