Cllena DC/DC 12V to 24V Boost Converter 50A 1200W Step Up Voltage Regulator Power Supply Voltage Transformer (Input 10V-16V)

These do what they claim, boost 12v to 24v at 50a. Also you CAN use them in parallel for more current. What is TOUGH is supplying them with enough 12v power.I used two in parallel to achieve 100A to an inverter (Why? Just experimenting.) The inverter kept faulting, so I thought these couldn't supply quick surge current... WRONG. The large 12v battery (connected by 1ga wire, powered by a running alternator) voltage would drop. I put a 5 Farad capacitor (input side) to catch drop and now these deliver some insane power and handle >3000w of surge (x2 in parallel).Most of the reviews I'm reading clearly aren't supplying these with enough power.A few notes. In my testing, they stay cool. They don't do any obnoxious beeping. They are pretty expensive but I'm satisfied.

Working great so far. The output is exactly as stated. The size is great for installation in small spaces.

I am using Milwaukee 18M batteries to power a 12V telescope in the middle of nowhere. This device works perfectly to reduce the 18V battery to 13.8V which is perfect for my 12V telescope.

I purchased this to use with a dewalt battery to step down the 20v to 13.8 for running a trolling motor on a small boat.Works fantastic, Holds a solid 13.8 volts even under load. I can run around the water for a few hours on a single charge with these batteries and they weigh so much less than any lead acid car battery.Great little gadget im sure ill find uses for another.

Installed by a pro but only worked fo TEN minutes, powered a 300 watt inverter which only drawed 5 amps. Did not offer sq trade plan

We ordered this to power an inverter that requires a 24V DC input. When the inverter did not power up, we contacted the manufacturer. They were prompt and courteous in their response. They told us it cannot be used to power an inverter so we returned it. Overall, we think this appears to be a well made item and, except for using it to power an inverter, we think it is a safe item to purchase.

I bought this the 36v to 24v 20A so I could power a 24v kid's ride on toy that should draw a maximum of 15A. No moving parts, no pinned connections to worry about how to solder, just apply voltage and it works! If you try to price anything similar from a big electronics store, it can be difficult to find and very expensive.Both I and a child rode the ride-on around for 20 min or so. Converter was not even warm. Hope it continues working as well as it has initially.Instructions were clear and concise.

Works perfect! I was a little worried about doing it since I didnt see anyone with the set up I was trying to achieve in my RV. But basically I installed 12kw of lithium’s in my 5th wheel but its all 48v so I still had to keep the old flooded lead acid batteries for all the lights, slides, jacks, etc. I took 4 of these and wired them into my 48v lithium and then on the other end wired it right into the same wire the old 12v batteries were. Gives me 120 amps of power so all of the jacks work flawlessly and the lights are steady. Most importantly it saved me a ton of space and weight, these things are tiny and I just made a piece of wood to mount them on up and out of the way.
