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.

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.

Worked great

Second time buying one of these. First one was a different brand and it broke and had to send it back. So far so good, this one is working great.

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

I ordered this for my golf cart LED lights. They require a 48 to 12v step down at 30 amp. This thing does not work - not power is being monitored on the output end.terrible product

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.

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.
