Mellif DC Power Adapter Compatible with Milwaukee 18V Battery, 18V to 12V Step Down Voltage Converter, 180W Inverter Automatic Buck Converter Regulator for Golf Cart Led Strip Light (Tool Only)

Works good but will drain the battery if left connected to the battery. Recommend a switch be installed between the adapter and regulator if left on the battery. I use it for ice fishing unit.

Works good so far , using for diy power box

This little device has so many applications that turn my 18v batteries into mini power centers for the automotive repair industry. I have saved so much money building my own testing platforms such as trailer testers, individual light testers and isolation testers for work. I have also incorporated it into a stand alone power center for my side my side to remove strain off my vehicle battery for the lights and electrical add ons I use, seat heaters, defrosters, portable 12 volt power on the trail, and camping!Will definitely be buying a couple of more to keep from having to move it from one platform to another, which is easily done with the handy flip up connector supplied

It seems the voltage step down always draws power from the battery no matter if youre using it or not. If you have older M18 batteries like me, this can kill the li-ion cells beyond repair. The battery I lost from this was about 10 years old. One of the cells was discharged to zero and wouldnt take a charge. I would install a cheap switch in line with the battery leads, take out the fuse or disconnect the battery when you're not using it. All in all this is a great idea if you already have M18 batteries and dont want to pay 50 bucks for another power wheels sized lead acid battery.

Put this on a power wheels knockoff and it works great. Glad I used the inverter as to not burn up the wheel motors.

Works great runs my sprayer pump amazingly

Used this product about 5 times over a couple of months period. Then it just stopped working. I reached out to Melif through email to get a replacement and never got a response. So then I called and left a voice mail and never got a response. I was finally able to speak to a representative a month ago. He informed me they'd send a replacement. I have not gotten a replacement or any communication.

Our daughters bronco would barely make it through the yard that’s relatively flat, so I started looking for an alternative. This arrived quickly, was easy to install and works great. Sometimes have difficulty removing the battery from it but nothing too crazy.
