Higly versatile for DIY projects. Great purchase
Color: with Step Down Converter
Output on all of mine measure 12 - 12.5vdc. Quality! These are extremely handy for utilizing Ryobi batteries where/when there is no power. DIY connect them to a 12v outdoor camp shower pump, or submersible transfer pump (use a plastic ammo box as a housing, install a 12vdc switch), or connect it to a 12v female car plug to run various devices. Purchase the model without the 12vdc step down, connect it to a DROK 5v 2a stepdown, then connect that to a bank of USB charge ports.... I've made several DIY "power packs" that run my wifi security cams during power outages. (5.5x21.mm male end cable) So many possibilities, limited only by your creativity. ... show more

Would buy again

I installed this on my son’s 12 volt power wheels tractor. The original battery stopped working. Now I can use my Ryobi still battery’s in his tractor. Much easier to charge them and change them out then factory. Great price. Easy to install. Would buy again.

Worked perfectly for my Ryobi batteries
Color: with Step Down Converter
This 18V to 12V step-down converter exceeded my expectations. It delivers a stable and consistent output, which is exactly what I needed for powering my 12V devices safely from an 18V source. Performance has been flawless with no voltage drops or overheating, even during extended use. Installation was simple and straightforward, with clear wiring and a compact design that made it easy to fit into my setup. The build quality feels solid and durable, giving me confidence that it will last over time. Overall, this converter is reliable, efficient, and well-made. It does exactly what it promises without any issues. Definitely a 5-star product and a great value for anyone needing a dependable voltage step-down solution! ... show more

Defective part and no customer service
Color: with Step Down Converter
Junk. Installed on kids power wheels dune racer and the reverse and low speed work but the high speed will only work if it's put into high speed while driving in low speed. So it won't just start out in high speed and if the kids let off the pedal in high speed it won't start back up again until it's put back inyo low speed. Very unhappy with this I wanted a solution to resolve junk battery issues and make more fun for kids but apparently I just wasted money and time and there's zero customer service contacts to ask manufacturer why this is happening. ... show more

Good solution to use power tool batteries for 12v items
Color: with Step Down Converter
Got tired of killing the portable generator starter battery by leaving things on and then having to wait days for a new one. I replaced the battery with this and it allows me to use the drill tools to start the generator instead.
