    This worked in a pinch on my big rig truck after my large inverter went out. But it had a hard time keeping up with just my PC after an hour. I still recommend it in a car.

    I purchased this to use while on the road traveling for sales to charge my MS Surface. When plugged into the cig lighter your supposed to get 120 but everytime i would plug in my surface charger it would run for maybe 5 minutes before throwing this obnoxiously loud error buzzer. I tried two different chargers, one travel & the standard docking type, both did the same. The cable is extremely short as well. I dont know where they exepct you to mount this and not stress the cable or be able to route it anywhere hidden. Returned & will be trying a different brand.

    Best buys customer service for return treated me as if I was disposable. The 20 year old manager treated me like I was child, ripped the opened box while I inspecting it. Did not except my return because "it is after Christmas and we are being strict with returns". The manager on the customer service line never called me back. Why would I ever buy something from Best buy again.
