It was purchased for charging drone batteries during outdoor shooting. It has a DJI drone, but unfortunately the C1 port is not compatible. The C2 Port accurately supports 65W fast charging reliably. However, I decided to get a return/refund because it was the product I bought with the original 100w charge, and it was in the store. Handled well. The delivery took about two weeks and was good, in the case of me, unfortunately, the C1 port is not compatible with the drone, so I processed the return. Other than that, the product is very high-end, and the same as the product description, the C2 port, etc. show stable performance. The price is reasonable and it is considered to be a good product that is reliable.
