Our take on the NEXPOW OBD2 Scanner Code Reader

The NEXPOW OBD2 Scanner Code Reader is a plug-and-play diagnostic tool for any car built since 1996. It draws power from the car's OBDII port, shows codes on a 2.8-inch color LCD with a white backlight, and reads live data such as coolant temperature, speed and RPM. Lifetime free software updates are included. Its best new price is $18.00 at Mercari as of November 8, 2026, the low end of what it has cost across the 6 stores that carry it new.

Questions and answers

Will it work on my car?
It works on any car or light vehicle built since 1996 with a standard OBDII port. That covers most US-market cars, but not older pre-1996 models.
Does it need batteries or charging?
No. It draws power from the car's OBDII data link connector, so you just plug it in and turn the ignition on.
Can it read ABS or airbag codes?
No. It reads standard engine and emissions codes plus live data like coolant temperature, speed and RPM. ABS, airbag and manufacturer-specific codes need a more advanced tool.

The scanner with its attached OBDII cable and a user manual. No batteries or extra cables are needed.
Is $18 a good price?

Does it work with a phone app?
No. All readouts appear on the built-in 2.8-inch color LCD; there is no Bluetooth or app.
