This is a great product. It is light and easy to handle. I was recently on a camping trip when the converter on our camper stopped working. We purchased this charger and set it on the 3 amp maintain mode and kept our battery fully charged for 14 days. We already had one back home now we will keep this one in the RV for a backup if the converter were to go out again. Would recommend this charger to anyone who is looking for one.
