If you're looking for something portable, grab any of those big portable chargers from Harbor Freight. They've got a tire inflator, usb charger, and all sorts of stuff built in. |
Just my .02 on these.....years ago I wondered, why do coders pay $400+ (at the time) for power supplies, why not run down to walmart and get something like you've posted and save $400?
It lead me down the rabbit hole of what constitutes "clean" power.
Meaning you plug it into the car and the car wants 70 amps or something, clean power supplies are regulated to stay at 13.6 volts regardlesss of 1-70 amps. Whereas the cheap devices may spike to 16 volts...remember v = ir, so as i goes up, v goes up if unregulated or loosely regulated. That's what led me to the RV power supply--the RV has its 12V appliances riding on this device, and excess juice charges its battery. If it didn't stay at 13.6v max, it would fry a lot of stuff....that's when I said why pay $450 when something without the fancy casing and gauge can be done for $130? Just diy that's what everyone here does anyway...
EDIT this looks great but now it's almost $600--when I was watching the video for the ABS/DSC hydro pump replacement, I noticed the gentleman had a device hooked up to his car and wondered what it was. Ideally when you're doing all those functions, you want to be like a dealer and have the car plugged into to power, not relying upon the battery...say the car goes into power save while you're doing the ABL bleed or something...

You can build one yourself, and spend the savings on Game Stop stock!
