I was at Target and saw a 700 watt inverter made by Vector. It had a digital readout to let you know the batt voltage and power output (in watts). They also had one that was 400 watt with the same digital readout. I already have a 115 amp deep cycle batt in my shed. I have a small plug in 70 watt inverter for my laptop. I was interested in what other members have and what they use them for. Great for poweroutages...but there are few here and rarly last more than a few hours...haven`t had a hurricane here...they always miss us (Tampa).
