I bought it more out of curiosity than anything else. I purchased the 10 amps version first and it was ok in charging my motorcycle battery. I decided to purchase the 20 amps version to see if any good was in charging a regular car battery. When I start working with the 20 amps version in the beginning was not doing much and was giving me a 601 and 602 error message. Further inspection after checking al the cable connections got me the surprise that the fuse included with the unit was a 25 amps protection fuse. It was odd since the unit itself is listed as 20 amps. So, I change the 25 amps fuse for a 20 amps fuse, and everything came up to properly functioning and proper working condition. So far, the device is charging a regular car AGM battery but is not the fastest system to such task. In an emergency situation may be a solution but, under normal conditions is just a fancy toy.
