Ampacepower

I purchase a Ampace P600 on Amazon and it was a very bad experience. The device was mostly non functional on arrival, but worked long enough to hear the noisy cooling fan, that comes on and off, that everyone is talking about. But the real surprise came when I looked at the user's manual and discovered the life of this battery based product is less than 1000 charge cycles. And even at 1000 charge cycles the batteries capacity is diminished to 70% of capacity. This is a surprise, since it is suppose to have Lithium Iron Phosphate Batteries (LiFePO4) which have a much longer life? More like 4000 -8000 charge cycles. So how is this possible? Because the seller indicates in small print that the product has a "hybrid" construction of lithium ion batteries? Which means less than 100% LiFePO4 batteries. Different Lithium ion battery types mixed and with a mix of different battery chemistries. Given the volatile nature of some types of lithium batteries, and since it was going in my house, I decided I would not take a replacement unit offered. This product is not made in the USA and product safety is of concern.
Upon informing the seller of the defective unit I received, the seller would not provide a return label and basically gave me a hard time. He requested I send it back at my own expense. Had Amazon not had a big stick over him, I never would have gotten it returned. It took two weeks to get a refund with lots of correspondence. Plus the batteries make this hazardous freight, with restrictions. For a return.
So buyer beware.
