Black & Decker Electromate 400

I bought this to run a credit card machine and a couple of light bulbs while selling my products at craft shows and markets. It will run the credit card machine all day with no problem, However, the battery goes dead after just a couple of hours when running the lights. I don't know, maybe I just expected too much.

This is by far the best portable power supply/booster I have ever owned, and I have had 3 other brands before buying my Black & Decker. The battery life is excellent and has the power to jump-start an almost completely dead battery. It holds it's charge even when stored for weeks. The Walmart price was the best value for the money!

It was used one time. It would not recharge. I called Black and Decker. They would only replace it if I drove 50 miles to the nearest service center. Decided to return it where I bought it only 5 miles away.

Owner of '67 Buick Special that is very sentimental. In other words, starts when she's warm and keeps going based upon maintenance. Needed jumps from cold, tire went flat and charge of other things all in one day. Black and Decker; You are so loved in Lodi, Ca. Amazing to buy something that does exactly what it says it will do in this day and age. Done deal!

Compact, nicely laid out package consisting of air compressor, battery charger, trouble light and assorted power outlets, the Black & Decker Electromate 400 is a fine resource to have at the ready in one's garage, or, especially during the risky winter driving months, in one's vehicle. I charged my new unit up upon finding it delivered to my porch on Friday evening. The very next day, I used it to jump-start a lady's weak car battery in the supermarket parking lot. 'Worked like a charm.
