Model: EC-YAC04 I used this to charge my ThinkPad P series while on the go. I mainly carried it in a bag that holds a 16-inch laptop. There are some scratches from storage, but it has not been used in environments where it could be submerged or experience condensation. It is an excellent charger that stably supplies around 100W of power. I have never had any problems with heat or anything else when supplying 80W to 100W continuously for 6 to 8 hours. When not charging my PC, I charged my other devices like smartphones and earphones. The maximum 100W charging is the fastest quick charging for most devices, making it convenient.
