Fantastic well made and does what it should do, very happy and highly recommend
This battery adapter completely solved my problem of having a couple older tool with Nicad batteries that were no longer any good. No with this adapter I can use my lithium batteries to power these tool and get more life and use out of them. I had no idea that this was remotely possible to do this. It is a win win for me!
Great quality and works perfectly. Will be my go to for adapters moving forward. Definitely better quality than anything you can find on Amazon.
Adapter took a 10 year year old NICAD battery Harbor Freight impact wrench and made it perform better than new with my RYOBI lithium batteries . It added a few inches to the impact gun but that is how it had to be.
I love that I can keep my same platform and increase the tools I have without having a dozen chargers and batteries.
I was very impressed with your product
I have a variety of tools and it is too expensive to purchase new batteries for all of them.
I will definitely be purchasing another one
I love my Hercules tools, and have 3 chargers and numerous batteries. That said, I need a few other tools, like a Milwaukee 2 gallon vacuum, and other assorted red and yellow tools. The adapters allow me to use my Hercules batteries, saving me TONS of money!
The adapter fits my tools perfectly and performs flawlessly so far! It has brought new life into the tools from the old nicad batteries! Great idea… very satisfied with the purchase!
The adapter fit perfectly. I now have a way to extend the life of my bolt-on drill.
Works nicely. It does have a fair amount of play between the battery and adapter but otherwise decent quality.
Update, 7/15/2026 to 5 stars: The company was quick to correct the problem by replacing my damaged drill and sending a replacement adapter. Not sure how the original slipped through their QC, but I do know they took the matter seriously and work diligently to see things through and make sure the problem doesn’t happen again.
Update, 7/8/2026 to 3 stars: Support was quick to reply and open an investigation as to my problem adapter. Hopefully this is just a “one off” thing and they can double check remaining inventory for the issue. I would advise anyone receiving the adapter to double check polarity before using it. This can be easily done with a multimeter if you have one handy.

Totally recommend, my AEG battery works a treat.
Works a lot better with the adapter, takes 3-4 vacuums before I charge it.
Perfect.
Service, support and shipping were excellent. The adaptor matched up to the Milwaukee 18V battery and works as intended. No issues encountered.
