Overview
Shaped like a dongle, this OBD II scanner pairs with a phone or tablet over Bluetooth and draws power from the car diagnostic port. It reads codes from every system and supports bidirectional commands.
Its pull is easy-to-carry capability: relearn functions and resets that normally need a dealer tool, with updates that stay free. The downside is how thin the listing is. No screen, battery, dimensions or vehicle list appear, and the only included part named is the scanner itself.
Who it's for
Home mechanics who already carry a smartphone in the garage and want an easy storage option. Anyone who needs rugged handheld hardware will prefer a unit with a built-in display.
Pros and cons
- Small dongle powered by the car
- Works with Android and iOS
- Relearn tasks for brakes and throttle
- Updates stay free for life
- No standalone screen
- Vehicle coverage list not shown
- Dimensions and weight unlisted
- App dependence for every function
Performance notes
Because the app does the display work, speed depends on the Bluetooth link and your phone. Because the car supplies current, there is no internal battery to recharge. Bidirectional commands only help on vehicles and systems the software supports.
