Heavy Duty. Reliable. Quality. Our High End AC Power Cables feature a heavy duty cable design. The importance of a High Quality cable cannot be over stated. If the connection is faulty or the cable is bad, it can make all the difference in the quality of charge delivered to a battery. These AC power cables work with all of our units (except the #1000 models) and will also work with most devices that use a 2 prong universal power input.
