18-volt to 20-volt adapter and Phone charger.

It worked as advertised. It plugged into my older Dewalt 18-volt tools without any problem. I could then slide in a new 20-volt Dewalt battery and continue using my older Dewalt tools without having to go and buy new 20-volt tools. The 18-volt tools seem to work fine with this adapter and a 20-volt battery. It also saved me from having to try to find older Dewalt 18-volt batteries and it also has a USB charging port for my phone that works great when I'm out in the field working without a 120AC Volt plugin and charger. The USB port charges my phone with just the adapter and a 20-volt battery when not on a tool leaving me to continue working using my 2nd adapter and 20-volt battery while my phone charges.

I am glad I found this adapter and my 18v tools work perfect with the new 20v batteries. The review I read about release being difficult was true. After examining the reason it was difficult to release I found that specific pressure applied to end area of release (not center) solves it. I am glad I made this purchase !!
