Works great
Size: 24/12V 70A
Easy to install. Works great on my Humvee

Very high quality and simple to install.
Size: 24/12V 70A
Excellent device for converting from 24v to 12v. I'm using it in a large 5th wheel with a 24v battery bank in order to provide power to the 12v systems. With 70a of supply power there's no real need to install a 12v battery. The 70a capability provides more than adequate power to run our Lippert electric leveling jacks as well as for the day-to-day 12v systems in the RV. Construction is excellent and quality of the packaging was clean and neat. Installation was very simple by using a common ground connection to the 12/24v bus bars. Provide 24v on the input side and this will provide 12v on the output post. Heat generation is very low during typical operation. Output voltage is adjustable to match your exact needs or to account over voltage drop from the location of this converter to your main 12v panel. Absolutely would recommend this if you need to downconvert from 24vdc to 12vdc. ... show more

Victron Orion 12/20 Converter
Size: 12/24V 20A
Works as designed, fan when it does come on is quiet. This unit isn't Bluetooth like my other Victron products. I use this converter to charge my Bluetti AC180 which is a 1152wh lithium battery bank. I use it to extend its battery life during power outages at home by connecting the Victron converter to my 200ah or 2564wh lithium battery bank to charge the AC180. I run a refrigerator and a large upright Freezer and my 75" LG smart TV while the power is out. Works great and I get about 280 watts feeding into my AC180 Bluetti which limits its input charge to 10 amps. thru the solar charge port. Nice converter so far. The adjustable voltage dial is suppose to bust the voltage up to 30 volts but my Victron 12/20 only busts to 28.6v turned all the way up. Without the Victron Orion converter I was only getting about 100 watts of charge capacity and now I'm getting 280 watts of charging which is almost triple the amount of charging I was getting. I recommend it if your looking to increase your charge capabilities. ... show more

Works as intended

I have a camper that I wanted to power while in storage. I was carrying the lead acid battery back and forth from the house. I had a little buck converter that I had rigged to use a tool battery to work some 12 volt items. The buck converter was able to run the lights but not much else. I saw this and thought I would give it a try. It powers the stabilizer jacks and runs the slide in and out. That makes it easy to do maintenance and load and unload the camper. It also allows me to start and run the fridge the day before packing so it is cold and keep the lead acid battery at the house on a charger until I am ready to leave. I don't think I would travel with it without the camper battery. It will also run the inverter I have for small loads. The only thing I would change on it are the posts. They are a little close together and a little difficult to wire without touching the case. I am considering a second one so that running the slide is not so stressful and I can run higher loads on the inverter. ... show more

Company won't uphold the warranty. Unit shorted out due to positive insulator melting on a 24v system. Everything installed properly and not in use when it shorted out and almost burnt down my camper. Sent in for warranty and was denied only for them to try to sell me a new one at a "discounted price" that was higher then Amazon price. ... show more

Will not power a Slide!
Size: 24/12V 70A
It is important for those thinking about using 24VDC or higher voltages. This unit states it will deliver 70 amps, but it will not supply the inrush current needed to start the motor. Place a 12VDC battery on the output of the buck converter or off the relay for your slides. Mine is a relay with a 60 amp auto reset breaker on it, directly connected to the batteries. I used a seal AGM battery for a lawn tractor for the slides and trailer emergency brakes. (Edit) 5.9.2021 Forgot to mention that this is a great device, so far. It will run our furnace blower just fine. I used upstream/downstream breakers instead of fuses. (Edit 10.6.2023) I have been using this for over two years now and have left it on for as long as a month at a time now. I have had to do nothing to it. Still a great device. I will add that in my configuration it doesn’t charge my agm battery fully. Lucky I don’t need to much from it. I have not had to replace the battery even though I am charging it to only 13.2 volts. ... show more

I bought this for an RV 24 volt upgrade and this takes the 24 volt power from and converts it to 13.2 volts. I have this on at all times now for two weeks of use and ahas provided 12 volt power flawlessly to my RV side, to include the leveling jacks which draw 50 amps, with no spikes or dimming of the lights. This device also provides the 12 volts for the emergency breakaway. What I don’t like about it is how the wires are connected to the converter. Because of distance from the battery, I went with 2 AWG and found mounting this challenging. The top lugs could only fit in the 9 o’clock, 12 o’clock, and 3 o’clock position because outside bows out not allowing the lug to sit flat (See Pic). Also the studs for the posts only have a bolt on the bottom, and are not big enough with surface to surface contact for 2 AWG lugs. (Also Visible in Pic) The studs also come with a thumb screw which for mobile applications couple shake loose. I secured these thumb screws with Kapton tape (See Pic) Finally, ground lugs go to one stud for the 24 volt and 12 volt side. One stud won’t fit two 2 AWG lugs with enough threads to secure the thumb screw (see Pic). Perhaps one or two threads will catch, but not enough to keep tight. ... show more
