It was easy to order this product online and it arrived when promised.Though we haven't needed to use the Xantrex 600 yet, we did charge it tested just fine with my small electric coffee pot. When the power was out because of Ike, that is what I missed most! WE are going to also order a 1500 because 10 days without power will use up 600 watts in no time. It powers our fan also.
