Airbrush Kit with Compressor

TLDR: When I opened up my first air compressor and airbrush I found that it didn't work. I got a nice burn on my thumb along with a puff of acrid smoke and some sparks when I went to figure out why. My compressor came in parts when it should have come whole. It seems the biggest part is the battery wasn't assembled properly. The on/off button is also very loose, but I couldn't tell you if that is problematic. Also, it stinks terribly. I'm assuming its cheap paint. The Full Story: I was quite excited to use my new airbrush today. Too bad the product that I was sent was barely put together. Yes, you get what you pay for... usually. I got this because I recently got into Warhammer 40k and I've got many minis to prime and paint. I got this item because of Ninjon the painter/YouTuber. I figured, at the very least, it would be good for this project and if I want to move on to bigger and better things later, I could still do that. I plugged it in to charge last night and was a bit dismayed when I saw that the indicator on the bottom didn't light up in any way. This morning it simply didn't work. I'd have just sent it back for a replacement, things happen. I could wait, but I can't do that now. It was ordered too long ago. See, I ordered the item and I then left my home to be an intern for a few months. I never got a chance to check it out as it arrived too late. So, since I was screwed anyway, I opened up the bottom, hoping to see that the battery just had a cap on it or something to keep it from being used before it arrived. There are no instructions that go with this, just a print-off that's wrapped around the compressor itself. It's more or less a warning to screw the airbrush or hose in without damaging the fixture. I figured out pretty quickly that the battery works since it burned me when some loose wires completed the circuit through my digit. That's really on me. I've never really worked with this kind of thing or been burned like that. So, now I know. I'll remember that for later. I think then that I can repair it. It seems like I could solder the wire to the connector, but I don't have that kind of equipment. I'll see if a friend has one. I'll definitely look at a tutorial or two before I try. Besides the battery problem, I can say that the on/off switch is also very loose and it rattles. The paint also smells absolutely terrible. I hope everyone else faired better.
