DC 12V Boost to 19V 10A 190W Boost Converter Power Converter Waterproof Module Transformer is Used for Golf cart, CLU bcarand Other Vehicles

Works perfectly. I use this between a 12V LifePo4 battery and an EcoFlow River 2 Pro power station to “fool” the power station into thinking it is receiving higher voltage solar panel power.That allows it to charge at up to 220W rather than the 100W limit that would be for 12V battery charging. You lose a little efficiency way, but get to charge twice as fast.

This thing is built like a tank, works really good. Good thick wires, a good output regulation. Good product at a good price. No complaints here.

Ordered this part to use our new starlink mini to run off a dc current. Starlink unable to run on thin wire at 12 volts. This unit pumped up the voltage to 24 volts. Now I can run our Starlink mini on our dc power in the travel trailer.

Stopped working after a few months of use. I was using this to power a computer monitor in my camper that uses 165w max, 55w typical according to it's specs. Worked perfectly for several months and this morning I turned on the computer and the monitor would not turn on. I measured the converter's output and it was just a few volts, I measured again after some time and it was just 6 millivolts. It looks like a very well built unit, but apparently it's not reliable despite it's beefy metal case and heatsink. Very disappointing!!!

Works.

Works as advertised

Gave me the power I needed for my project.

I use this to speed the recharging of my EcoFlow Wave 2 air condition from my 12vdc camper van solar power system. The Wave 2 power input "auto-switches" "car" or "solar panels" (where current is limited by the panels). The Wave 2 also tops out at 8 amp recharge rate in "car" mode for either 12 or 24 volts, limiting to 96 watts at 12v. However, the Wave 2's auto-switching/sensing algorithm is flaky - it was occasionally popping a 30 amp breaker at 12vdc. This power supply solved two problems.Everything seems much better now at detecting that it's not a solar panel and this power supply puts out a solid 8 amp without excessive heat (it's mounted on a slight dampened/isolated fridge fixture aluminum structure for extra heat sink, though probably not really needed).It has held for many trips, so far taking the vibration well.And, it provides a good 192 watt recharge rate, twice as fast, and no more popping circuit breakers.UPDATE, MAY 2025: Still working great! It's nice to have power gear that I don't have to think about or worry about!
