They work

This 24V to 12V DC-DC Converter has proven to be a reliable solution for my power conversion needs in my portable power station. One of the important features for me is its waterproof design, which provides peace of mind when using it in various environments, particularly outdoors with rivers/lakes/boats. On the positive side, the converter consistently delivers stable and efficient power, which is crucial for my electronics. It handles a substantial load with ease, making it suitable for high-power applications under the specs of 360 Watts. The very compact size and build are additional plus points, as they ensure durability and make installation pretty straightforward. However, there are a few drawbacks to consider here with this little unit. The unit can get quite warm/hot under heavy load, so I would add adequate ventilation to prevent overheating. This is you plan on running it a lot. Mine never gets hot under the general use it gets. Only when I stress test it at full wattage for over 30+ minutes. Additionally, while this unit is generally reliable, the absence of detailed instructions might pose a challenge for folk who are not familiar with electrical installations. Ensuring correct wiring and setup is essential to avoid potential issues. Electric fires are no fun. Overall, if you need a dependable step-down converter for your 24V to 12V needs, this product is a strong contender for its low price point. Just be prepared to manage its heat output and ensure you have a basic understanding of electrical connections. Its performance and durability make it worth considering for all types of projects like my DIYs.

Works pretty well. Been using on my kids' Power Wheels for a little over a year (30 amp version) to convert 18V Ryobi tool battery to 12V output. My one complaint, as others have noted, is that this thing doesn't like cold. One review says 7.5V output under a certain temp. I haven't checked that, but I do know that the car won't run at all under a certain temperature, so whatever voltage it is, (the DC motors shouldn't care too much about that, they should just run slower). One star off for that. If you sit there for a few minutes with your hands on the unit, it warms it up enough that it starts putting out enough amps and voltage to get the car going, at which point it will keep itself warm from using it. A little annoying, but it's good enough at this price point for my kids' toys. My youngest spends hours per day running this one in particular and we haven't had it fail yet. The other one from a different brand never had the cold issue, but that one failed today and it got significantly less run time, so I think that's a worse tradeoff. Buying another one of these to replace the failed one. I wouldn't rely on it for some critical outdoor tool though. That would be bad if you relied on it for emergency lighting or something and it wouldn't work when it's cold outside.

Zero stars. It quit working. Used less than half a dozen times. Powering 3 LED lights and a heater, well under the max amps and watts.

This works fine inside but when exposed to cold (temps around freezing or below), the output voltage is about 7.5 V. If I bring it inside with my 24 V backup, the temp will start being around 12 V. I was hoping to use this on a small (300 W max) inverter to run some lights on the outside (but protected from precipitation) but even though the load from my charge controller would turn on, the inverter hooked to this will not unless it is an evening that is above freezing temperatures. This is a common issue with all of these devices because they are simple and don't adjust themselves for temperature (resistors, capacitors, wire in general) have markedly different conductive/capacitance qualities at various temperatures. Device works. Beware that probably all devices in this class behave like this, and if one wants a really stable 24-12 power supply, one needs to get something that costs about 10 times more from Victron. Currently using one that I actually just had being mostly unused. Synopsis: For situations where the temp is measurably above freezing, say 5 C (maybe 40 F), these devices will work.
