Anbull 110V to 12V Converter, ON/Off Switch, 12V DC Adapter Transformer, Max 50A 600W Power Supply

So far it is working perfectly. Well built. Never used one before now. Can't make any other comments. Planning to buy same product in the near future.

Good product works great

Excellent for use with Velvor Diesel Heater converting from 12 volt to 110. Reasonable price and made with quality for reliability and long life.

Seems to produce good power. It was easy to set up and came with an all needed accessories. Fab does get pretty loud when there is a draw on it. I may swap out the fan for a better quieter one.

Got this to run some 12 volt pump , works great

It was easy to mount and wire up! Used it on a 12 volt dc gear motor!

This has made my life easier no charging a battery everyday ❤️

There is no on/off switch (which you could add one) so it’s best to run it off a surge protection power strip. The fan does also run at all times and it pretty noisy but shouldn’t be an issue if your looking to run audio equipment with this. Tested with meter for voltage right out the box and was showing 12.46 v no need for adjustment, not sure if there even is one. The terminals connect really easy with 8 ga wire and ring crimp ends, you just screw them down and plug it in. It’s nice that this doesn’t require you to cut a cord to power this one is included. Haven’t had any issues or loss of voltage after a week of use and provide plenty of current to run an amp and subwoofer, cheaper than a 12v battery and battery maintainer. The power max costs over $100 this option is a much better deal.
