Tire Inflators
Cordless vs 12V Tire Inflator: Which to Buy for Everyday Car Tires
For everyday car tires, a cordless inflator is the better buy: it airs up all four tires in minutes with no cord to route and no engine idling. Pick a 12V plug-in model instead only if you want the lowest price and prefer never worrying about a battery charge. Either type easily covers standard car tires — those run about 30-36 PSI, and every unit here reaches at least 100 PSI, well past the roughly 120 PSI ceiling any passenger tire needs.
OBD2 Scanners
OBD2 Scanners That Actually Read ABS and SRS/Airbag Codes
Most cheap OBD2 scanners only read engine/emissions codes over the generic protocol — they cannot touch ABS or SRS/airbag, which live in separate modules. To read a lit ABS or airbag light you need a scanner with explicit four-system (or all-system) coverage. Below, five tools that genuinely read ABS and SRS codes, with per-model truth on what each can read, clear, and command. The single most common mistake: buying a Foxwell NT301 or similar engine-only reader and expecting it to clear an airbag light — it physically cannot.
