DC 12V/24V to 5V 3A Step Down Converter - 12V Voltage Regulator Buck Converter Power Supply Transformer - 12V/24V to 5V 3A

Ideal for my Tesla that has a 16 volt lithium low voltage battery. Many devices can only accept 13.8 volts and overload at higher voltages. I incorporated this device into the cigarette lighter socket and it is brilliant. 10 amps runs my 35 watt mobile transceiver. Make sure to get at least the 10 amp version, if using this type of connection, and always have a fuse inline.

Great value and reliable, easy to follow instructions

Used to convert the 12v on the rave trolly to usb 5. Good transformer, low noise. Small with good terminals.

Works great, I use these with WLED controllers where I need to change the voltage. Means I can keep a 24V transformer and step it down for other lights without needing transformers for each set.

These are awesome... I've bought 4 altogether now for my 24v trucks and none have failed

Installed this regulator for my customer, and it worked well, the customer had issues of over voltage in his electronic equipment. This regulator solved that issue. Very happy with the overall service.

Ran it for a few hours into a 1 ohm dummy load at 5A and it barely got warm. It's pretty much exactly 5V, dropping to 4.95V at 5A. As expected but not documented, it's non-isolated, i.e. both the in and out negative terminals are internally connected. It does not have a low voltage cutoff so it will drain your car battery to 7V or less before it stops working.

I originally brought 4 of these to use in conjunction with my 48v solar system, inorder to run my 12v appliances (fridge, waterpump) they are very well made, and the cables are pre stripped to speed up connections. the input remains at 12v regardless of battery being fully charged which is really useful. The units have two mounting holes and werent bothered by my impact driver! the fuse it pre-installed with a spare in the box which was a nice touch. and on the back it shows you which are the input and output cables if you were unsure along with the ploarity of each. great product really good price. they also dont get warm through prolonged use and load.

These step down regulators really work well. I have used them in both solar and industrial applications. The price is great and they provide a lot of value for the money. These little buck converters are super easy to install and very durable as well.

Used this to knock down the voltage of a small 24V solar panel to 12V. The solar panel is then hooked up to a 12V battery to keep it trickle charged. Worked great for my application.

Does exactly what's needed and seems to operate as advertised.

Very compact Easy to install

Bought this for the raspberry pi 5 and its not giving even the 5 amps the pi requires and this is supposed to be 10 amps. Very disappointed.
