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

I use this to power a mini (beelink w/ryzen7) computer from a 12v battery system... it works well... doesn't get too hot. It's built like a tank. no problems.

These work great! I use the 19v one to charge my notebook in the van, I use a higher current 13.8v one for my Ham radio gear. They will keep the voltage stable, when the batter drops low as it. The expensive 13.8 volt high current ones will keep me transmitting, even when the main battery drops below 11 volts. Some of my radios act up when they drop to 12 volts...

I used this to power a ryobi 18v air compressor for the airhorns on my truck. So far it has been functioning perfectly. And b4 you get all judgemental about using a ryobi air compressor/tank, think about the fact that for $130 the compressor cost, and a $20 dollar inverter, I have a decently dependable air horn air supply for $150. Vice buying a $100 Chinese air compressor that wouldn't last a month. Overall I would recommend this product.

Used this to boost voltage from +/-12.8VDC to 19.3VDC for a Mini-PC. It will run for a loong time of a car battery!

Worked great to speed up the windows in my old Jeep XJ.

I use this boost converter to exercise my 12V LiFepo4 boat batteries over the winter. My PC has a 19V input so I connect this boost converter to one of my boat batteries and the output goes to my PC (core i7 rig). I measured the output under no-load and under load.. always dead on 19DVC. I work from home so my work PC is on from 9am-7pm most days and this device runs at just about room temperature all day long. Can't ask for more than that.

Many Power Stations require more than 12 volts to charge and won't charge for the car cigarette lighter plug. With this unit you can raise the voltage to a level that will work and charge the station! Now, I don't use it with my car but with a 12.8V lithium battery and it works just fine!

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!!!
