Few things are more annoying than the dreaded “check engine” light suddenly appearing on your car’s dashboard. It’s one of those things that means a trip to a mechanic, being without your car for a period, and big bills.

If you’re at all technical and DIY-minded, tackling car repairs might not be outside of your skill set. Here’s the problem: Cars are complicated things, and require computers to carry out diagnostics and repairs. Without one of these “car computers,” you’re not going to get far.

Also: This 200W charging beast can power six devices at once (and it’s smaller than you’d think)

Well, this is the power that the Topdon TopScan Bluetooth OBD automotive scanner gives you.
