I bought (4) of these. They have been great for the last 2 years. As I have more of the smaller 3s batteries, 2200, 1800, 1300, 450, these really fit my budget. I have a box of old laptop power cords so that is easy enough to cut the end and wire them up. I found I had Toshiba in there and the plugs were a perfect fit. I do use a 240w when I charge my 5s, 6s batteries. Brother has (2), brother in law has (2), friend has (3) of these too.
