As the title says, I am satisfied with my purchase.  I like that there is no extra power supply to keep track of and carry around to charge the device.  As far as I am concerned being able to just plug any standard work type extension cord is genius!  The AC power supply works as advertised but the inverter cooling fan is rather noisy.  You can hear it from one room of the house to the other.  The LED light is smart as LEDs use very little energy.  There are consistent complaints about the air compressor taking forever to inflate a tire.  The problem is not in the air compressor but the little black nipple at the end of the house.  One must, with the lever first up, push the inflation fitting all the way onto the tire valve stem by twisting the fitting and gently pushing until  you can see none of the brass fittings and then push down the lever to connect the hose and open the valve on the valve stem.  If you do this correctly, you will see the actual tire pressure currently in the tire on the air pressure gauge.  If the air hose fitting is not on the valve stem properly, when you turn on the inflator, the air pressure will initially say 0 psi until you turn on the pump and then the pressure will jump up to 100psi.  What is happening in this situation, is that the air compressor is trying to push against a closed valve.  It will VERY SLOWLY push air into the tire.  Make sure you have the fitting right and it will work very quickly.  Black and Decker should put a better air hose fitting on the end of the hose to eliminate this issue.As stated, everything works.  Ultimately, I will use the dc receptacles to charge the device via solar panels through a charge controller.Update as of 9/19/2009I have had this unit for some time now and have been charging it via the 12 volt cigarette lighter with a small 30 watt array using two Sunforce 15watt panels in parallel.  I use a Sunforce 7 amp charge controller to protect the battery in the device. I can easily charge this unit in about 6 hours from a depleted point at which the inverter auto shut off to protect the battery the night before.  I get 5 to 6 hours of light from a standard torche lamp in my living room with a 23 watt cfl installed.  I recently started charging it in parallel with a old jump starter pack I had been given as an anniversary gift at a job. If I am only using 6 hours of the sun, I am not storing all the energy I can.I now run the Electromate in the living room for about 5 hours to power the lamp and the Jump start pack gets a 75 watt inverter plugged into it and I run an identical setup upstairs in my computer room.I want backup power in an emergency and a very good way to get the bugs out is to use it continually so the problems will pop up at I time when I don't really need emergency power, instead of at the most inopportune time.
