Not great for my Pavilion PC
I used this to power my HP Pavillion PC. It worked for about 5 minutes, then the fan ran very loudly (as mentioned in another review) for about 3 minutes, then there was a loud pop and it was dead! There is no reset button or consumer accessible fuse. I had owned it for 4 days. It worked well for an 8 hour trip when it was powering a small DVD player, but I can't recommend it for anything that draws much power at all.

Thermal cooling fan
I have a solar panel with this inverter connected to one of my security lights. The best thing about this inverter is the thermal fan that only turns on when needed. Not many if any at this price range can do this. I don't know how much of a power load it will handle, other than the rated 400 watts, my sytem only requires 60 watts for the flourescent flood light. My duration of ownership is only 1 month now, so far so good.

Does the job with some noise.
This inverter powered my MacBook Pro which draws 85 watts using the power plug in a box truck I rented. The plug tag and inverter label read up to 80 watts while the manual states up to 100 watts for the plug. The heavier gauge alligator clip cables are for higher wattage applications or you may blow your power port fuse. The alligator clips connect directly to the battery. If you permanently hardwire the inverter buy 6 gauge wire with a 50 amp fuse up to 6 feet long or 4 gauge wire over 6 feet. Both included cables are 3 feet (91 cm) long. Remember, Volts x Amps = Watts. The inverter draws 512 watts when output is 400 watts according to the label. Output is a stepped modified sine wave and NOT sinusoidal.
When the inverter fan comes on it is noticeable like a radio between stations at moderate volume (took me some miles before figuring it was the inverter). The housing stayed cool at 85 watts.
When Black & Decker fixes their dead links the manual may be available at [..] (search for PI400AB). Lowes and Home Depot were [..]for this inverter.
