I had doubts on the product initially but upon receiving my order successfully and once I actually opened it from the packaging and held it in my hand it's very light and I am very careful when handling it like where it's plugged in is where it is always going to be as I take the charged battery out reinstall battery from flashlight EDC Item few hours or whatever later repeat as needed but yes it charges Lithium ion battery quickly I would say doesn't heat up the battery may be slightly warmer sometimes during charging the indicator light changes when it reaches a internal preset "full" 

Would buy again and am currently recommending to friends etc
