Choosing an OBD2 scanner
Begin with the systems and vehicles you need to diagnose, then compare software support and ownership costs.
- Confirm exact vehicle coverage
- Choose engine-only or all-system access
- Check subscriptions and update policies
PRACTICAL GUIDES
Build a smarter roadside and garage kit.
Start with tools that solve common problems, fit your vehicle and are simple enough to use under pressure.
Choosing a jump starter
Match manufacturer engine guidance to your vehicle and prioritize protected clamps, clear instructions and a pack you will keep charged.
- Check gasoline and diesel engine ratings
- Look for reverse-polarity protection
- Consider storage temperature and recharge intervals
Choosing a tire inflator
For passenger-car tires, power source, hose reach, duty cycle and an easy-to-read gauge matter more than a maximum-pressure headline.
- Compare 12V, battery and dual-power designs
- Check duty cycle and intended tire size
- Look for preset pressure and auto shutoff
Your first garage tools
Start with dependable general-purpose equipment before buying specialized tools for infrequent jobs.
- Use properly rated stands with a suitable floor jack
- Match socket drive size to the work
- Follow the torque wrench maker's storage guidance
