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

The build quality is excellent — the casing is durable, heat sinks are well-mounted, and the terminals are clearly labeled and easy to work with. Setup was simple and intuitive. I connected it to my LiFePO₄ bank, and it’s powering LED lights and a small 12V fan without any issues.What I really appreciate is the constant voltage output even with input fluctuations, which makes it ideal for sensitive electronics. I’ve also tested it in a vehicle system and got consistent results there too.If you need a reliable buck converter for a project, camper, off-grid rig, or vehicle mod, this one is definitely worth it. Compact, efficient, and dependable.

This charges my 12v semi portable power system from my 24v solar power system. I've only seen it use 10 amps or less. but it charges fine.

Worked great

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.

I have ordered three of these 25 amp units from Amazon, between May 2022 and June 2022, that have not worked and I have returned to Amazon. I have experience with the 20 amp units that regulated the dc input to 13.8 volts and worked perfectly. Amazon must have a bad run of these 25 amp units. I just ordered a fourth unit utilizing Amazons excellent return policy. I will update my rating if the fourth units actually works. Again this is a problem with the 25 amp units.Update 6/14/2022, I just tested the fourth unit that I received and it was also bad. I have returned all four. This is the 8-40 volt, regulated to 13.8 volts, 25 amps. DC840138-25.

For the price, this is a great item. It works perfectly for to specs.I personally had an issue with electrical noise on the golf cart. I purchased this to provide 12V to an audio amplifier on a 48V golf cart. Unfortunately, the electric brake caused quite a bit of noise to be transmitted though the 12V. I attempted too move the convertor away from any other devices on the golf cart...even moving it away from the golf cart 6ft when I was troubleshooting, and continued to get the noise when the brake was applied. Part of my troubleshooting, I connected the amp to the stock converter and did not have this issue at all.Long story short, it works great for accessories, but if using for audio, I would stay away from this.

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.
