[PSA] Lithium jump starters make great 12V power sources for bench testing components.

Got a new radio? Want to see that it works before install? No problem!It's very easy, relatively safe as long as you're not too inept. Just keep your + away from your - ! Though these jump boxes have short protection built in so you can't even screw up that badly. via /r/cars http://ift.tt/2tSicCK
