Research-based review: We have not hands-on tested this unit. Our assessment is based on FOXWELL first-party documentation, current Amazon marketplace data, and comparison with verified basic OBD2/battery tools.

Quick Verdict
The FOXWELL NT301 Plus is a practical 2-in-1 option for drivers who want a basic OBD2 code reader plus a 12V battery tester in one handheld tool. FOXWELL verifies generic OBD2 fault diagnosis, DTC read/clear functions, I/M readiness, and battery-status checking. At our current Amazon snapshot of $79.98, its value comes from combining two focused jobs—not from unlocking ABS, SRS, or full-system diagnostics.

What the NT301 Plus Can Do
FOXWELL positions the NT301 Plus as a straightforward engine/OBD2 diagnostic reader with a built-in 12V battery-testing workflow. It can read and clear OBD2 trouble codes and provides a dedicated I/M readiness function for emissions-related checks.
The battery side is the reason to consider this model over the standard FOXWELL NT301. If you routinely want a quick battery-status check while diagnosing a Check Engine Light, the combined tool reduces the need to carry a separate basic tester.
What It Does Not Replace
The NT301 Plus is not a full-system diagnostic scanner. FOXWELL’s verified scope does not justify calling it an ABS, SRS, transmission, or bidirectional tool. If your target warning light comes from a non-engine module, move up to a scanner such as the FOXWELL NT604 or NT614 Elite.
Best For
- DIY owners who want Check Engine diagnostics and basic battery testing in one tool.
- Drivers preparing for emissions/readiness checks.
- People who prefer a self-contained handheld scanner instead of a phone app.
Who Should Skip It
Skip the NT301 Plus if you already own a capable battery tester or if your real goal is ABS/SRS/transmission diagnosis. In those cases, spending more for broader module coverage may be better value than duplicating a battery-testing function.
Alternatives
The ANCEL AD410 PRO is another verified OBD2 + battery-testing combination. The Innova 5210 adds ABS diagnostics plus battery/charging-system testing, while the standard FOXWELL NT301 keeps the same brand family but drops the battery-testing focus.

Methodology & Sources
This review uses FOXWELL’s official NT301 Plus product page and documentation. We keep the diagnostic scope limited to generic OBD2/engine-emissions functions because first-party evidence does not support broader module claims.

The Practical Takeaway
Buy the NT301 Plus if you specifically want one compact tool for basic OBD2 diagnostics and 12V battery checks. If you need more vehicle systems, this is not the right tier.
