Review on uxcell Voltage Converter Regulator: DC 12V to DC 19V 15A 285W Step-Up Power Boost Transformer - Waterproof Design by Daron Ellis

I've bought several DC inverters and none of them could even handle 3/4 of their rated output voltage. I decided to try one that is rated for a lot more power than I need. I used it to step up the voltage from the car's 12V plug to 19V to charge my Suaoki lithium battery. From this converter he pulled out 141 W, and 19 V remained at the output of the converter. And it did not warm up. Surprised. Only 4 stars because I don't know how long it will last.
