Adapter Upgrade for Bauer 20V Cordless Tools - Compatible with Milwaukee M18 Red Li-Ion Batteries for Power Supply, No Charging Function - (New Version) - Adapter Only

Works great. As intended. Fit is tight

Works great. Way cheaper than buying another battery seems to be solid. Very easy to use. Fits like a champ? I can't imagine it would affect battery life.

Worked exactly as shown. I used it to run Milwaukee M18 battery on my Bauer 20 volt cordless weed wacker. Worked like a charm for the price it is a great product.

UPDATE to my previous post below this paragraph: Taking this issue a step further, I bought, charged, and installed a Bauer 20V batt. I tried the test procedure in the manual. Will not fire. I loaded 2" brads into the Nailer. Fully pressed tip against the wood to actuate tip safety switch, pulled trigger and no fire, pulled trigger a second time and it fired, and every time after that. Switched back to a Milwaukee 18V batt using this adaptor. Again, no brads in Nailer, No fire during test procedure. Install 2" brads, again no fire on first trigger pull, but fires on second pull, and every one thereafter. Nailer will NOT fire using test procedure. It seems to me the Nailer may have an optical sensor or similar way of sensing it is loaded with brads. So, my ultimate assessment is that the Test Procedure listed in the manual is simply incorrect. In light of this I'll retract my "don't buy it" conclusion, this adaptor does work for the intended purpose.This product does not allow proper operation of a Bauer Model: 20131C-B Brad Nailer. This Nailer is a 20V Li-Ion battery type unit. I used this adaptor with a Milwaukee 18V Li-Ion Battery fully charged. The Nailer flashlight feature does work when the button for it is pressed. However, The Nailer will not fire the hammer cylinder as it should in the pre-use test process detailed in the accompanying instruction manual. This issue led me to return the Nailer to the store and exchange it for a new Nailer. 2nd Nailer exhibited the exact same issue. I believe this problem is due to the "2-pin only" design of the adaptor which is claimed to be necessary for "charging issues" across varying battery chargers. However, the adaptor details stated in the manual say that the adaptor cannot be used in a battery charging scenario. So why design the adaptor to avoid charging issues when it is not to be used in the charging process in the first place????? No confidence in this adaptor nor its claims. Too cheap to bother returning. Going in the trash

Easy install. Works great

Fit onto my Bauer Vaccum. Now I can use my m18 batteries all day long!

Does not work. Stay away. Very short return period and terrible product.

Product works as it should and very well built and quality seems very sturdy.
