Great product

It works

I had a small lithium charger that I got wet and when I plugged it in, it went up in smoke. So I ordered a this onboard charger hoping I don't have a repeat. This one is built like a tank. Works effortlessly. Only down size for me is the size a bit on the bulky side but it works.
