Review on Mellif USB Battery Adapter DM18RL: Convert Dewalt 20V & Milwaukee 18V to Ryobi 18V Lithium-ion Battery by Johnathan Delic

Revainrating 1 out of 5

Has NO undervoltage protection. WARNING!

That means you can easily ruin your good Dewalt battery if you let it run until it dies. Packages are not reloaded. The Dewalt tool has a scheme that prevents this, but you're using it on a Ryobi tool that doesn't have a scheme. This adapter MUST have it, but it doesn't. I ruined 2 packages before I found out about it. The figure shows a direct connection to the battery. WARNING!

Pros
  • Weight
Cons
  • Requires Socket
