HOMELYLIFE 10A 120W Golf CART 48V 36V to 12V Converter Voltage Reducer Step Down Transformer Waterproof

I bought the 10A 13.8V output unit with a 8-40V input -There were several thing that weren't clear from questions or reviews - here's what I found with the one I received;Idle current with a 13.8V source and no load was 7mA or about 0.1W - roughly 0.18 Ah or 2.4 Wh per DAY for a 13.8V battery. For many applications this could be left on without serious battery drain (great for my application)The output was showing 13.8V on a typical multi-meter with no other "load" - so there is no apparent "Low Load" protection or turn off on this model - It operated an electronic thermostat module that draws 48mA (0.67W) without a problem.This was quoted to require a 35W load to "turn on" in one post and in another, it was asked if it could run a low current sensor - the unit I received absolutely CAN run a low current load (This is necessary for my use)Input wires are 14AWG and outputs are 16AWGI shorted the output - it shuts off and then tries to restart - cycling quite frequently - maybe 3x a second - after about 20 seconds, I removed the short and the unit still works perfectly. More resilient than expected.With a just a 10W load, the unit functioned down to 5V input (not recommended but did not immediately cut off at 8V) as the current rises rapidly at lower source voltage, I wouldn't try less than 8 V for a full load but the unit will run below that (possibly requiring a low voltage shutoff as it doesn't seem to have one internally).This was measured with the unit I received Oct/2022

I bought this 12v converter to run motorcycle turn signals on my Radrunner 1 ebike and the one I bought 72v says it doesn’t “work” on a power voltage under 60v. Both of my batteries stock Rad and aftermarket fully charged are at 54.6v and it works great with both of them. I will definitely buy another one in the future if needed.

This unit is small and easy to connect. The only problem I have with it is the mounting holes in the base are too close to the body of the unit. The hole is so close you can't get a screw or bolt head to fit. A small amount of extra space would make a big difference. I would also like to see an "in-line fuse holder" included.

It works perfect so far

Muy bueno

I was getting 10 Volts to my landscaping lighting, which should have 12 Volts DC, and quite far from the 150 Watt, 12 Volt power supply. This device solved the issue. I let it run for a while and it didn't get hot. I will see how long it will last.

Perfect application. As I made my own custom led off road lights for my truck. I needed a voltage regulator but, this is a step up/down kinda deal that has high current of 10 amps. So I bought 4 units. 360 degrees of lights. Better than researching and experimenting, fabricating schematics and making circuit boards. Note: as engine idles and makes less voltage, it draws more current. As engine is up in RPM's it uses less. As long as I'm under 50 amps total, I'm good. And my lights don't dim or get super bright and burn up. Hence, my project is a total success. Only difficulty is finding a place for mounting. I used a relay switch box controller. They go between the lights and the outputs of the controller. The two Black wire are different. The input can be grounded, Output-NOT! The output wires both + &- go strait to the lights. The Red wire to the relay controller box. No problems, Nothing hot. No worries. My lights were made to run at 13.4 to 14 volts. Excellent! How long they last under the hood of a black truck is another question that I cannot answer.

The wires on this converter were a bit short. I had to add a length to reach the positive and negative terminals of my batteries in my golf cart. No big deal but a bit of a hassle.

The voltage off this device is very stable under heavy load and seems reasonably efficient with adequate heat disipation in an normal environment

Der Verkäufer hat ein gebrauchtes und nicht funktionsfähiges Gerät geliefert... An den beiden Bildern sieht man auch ganz genau, dass 2 gegenüber liegende Befestigungslöcher (2 auf jeder Seite) schwere Kratzspuren aufweisen, ein unmissverständliche Beleg, dass das Gerät schon ganz klare gebrauchsspuren aufweist. Das ist nicht gerade ein Zeugnis für besondere Seriosität. Ich kann daher den Verkäufer nicht weiter empfehlen. Das Gerät wurde daher auch wieder umgehen zurück geschickt.Heinz Beyersdörfer

funziona bene, tensione di uscita stabile

Le modèle reçu est capable de produire le 13.8V avec seulement 9V en entrée. Il est donc élévateur de tension et pas seulement réducteur... sur 16V il produit 13.8V. Testé sous 5A pendant quelques minutes il fonctionne bien sans chauffer. Je vais l'installer définitivement.

Works great
