This article is a quick reminder to buy (and use!) a surge protector on your (or your shop’s) scan tool(s).
The modern vehicle scanner has WiFi, a screen, and touch input. It is, for all intents and purposes, a computer, and it doesn’t like “dirty” power. Protect it as you would a legitimate computer. The modern shop has all sorts of power draws and supplies. Customer vehicles are already a questionable source of power—reduce your exposure when charging your tools at night and throw a surge protector between the power source and your tool.
