I have a small device that operates at about 72 watts with a 24v power supply, i want to be able to use the device on a car battery but since it will be at half voltage i thought about using something similar to this
http://www.ebay.com/itm/5A-DC-DC-Boo...-/262974092676 or this https://www.amazon.com/dp/B01EFUHGMU...ure-scomp-wm-4
Would i need anything else and most importantly would this be a safe and reliable way to use it on a car battery, since im sure these electronics are all made in china i wonder about the quality?
