About a month before buying this Black and Decker unit I bought the Energizer 84020 power station for what I thought was a great Gold Box price. It wasn't. I also discovered that though I like the Energizer's design quite a bit, it's not as robust as I had hoped. And so, greedy for more power I bought the Black and Decker Electromate also.I bought both of these as emergency power sources for the next power outage. We had one this past year that lasted 8 days. No, even two of these dressed up car batteries won't help much for 8 days, but I figured that I can at least bring one to work with me every day for a recharge.I like this Black and Decker unit. It has a nice built in light for emergencies, jump start capablilities, a robust tire inflator, and plug ins for A/C and D/C. The D/C outlet should come in handy should I have to charge our Kindle Fire during an outage.We haven't had an outage yet, so I did a simulated outage to test this power source. It kept a floor lamp burning for about 8 hours, one with a fluorescent bulb but welcome light nonetheless. Before running the light test, I played with the Electromate for about an hour. It wouldn't run my electric stapler/nailer. It did power an electric drill, a television, a DVR player, a radio, and a coffee maker. Not all at the same time, of course.The inflator in the unit is excellent. The air pressure gauge is small but readable with its light and accurate. I checked it with a hand held pressure gauge.The Electromate is heavy but not prohibitively so; it's certainly not a strain to carry it about.Overall this is a nice unit, with easily understood controls. The jump start cables aren't attached to the unit, not a problem for me. Extra inflator nozzles are included but aren't attached to the unit as they are on the Energizer.One feature this unit has that is not on the Energizer and some others is the vehicle alternator voltage tester.When the weather gets nasty this winter, I plan on carrying the Black and Decker or the Energizer with me just in case.UPDATE - I've noticed that this unit doesn't hold a charge nearly as long as the Energizer. The charge on a sitting Black and Decker fades after a week or two.
