FOXWELL NT201 vs. NT301 vs. NT630 Plus: Detailed comparison

Key things in common

The overall shape and design of all 3 devices are similar. They are all handheld devices with the screens on top and the buttons on the bottom. Besides navigational keys, there are also some hotkeys for quick access.

All three OBD2 scanners support full OBDII protocols. Although they work in almost OBD2 compliant vehicles, none of the OBD2 code readers in this article supports electric vehicles.

One more thing is that you can update software for free regarding what model is. This helps you save lots of money.

Key differences

Design and specifications

All 3 FOXWELL OBD2 scan tools may seem similar on the outside, but they have a few things unique to each one. Screen-wise, the NT201 has a slightly smaller screen measuring at 2.4 inches, while the other two are slightly larger at 2.8 inches.

Since you are looking at handheld devices, all of them are relatively light. The heaviest of them all is the NT630 Plus at almost 2 pounds. The NT301 and NT201 are slightly closer with 1.3 and 0.6 pounds respectively.

Each of these FOXWELL OBD2 scanners is powered using the cable and the OBD connector on your car, meaning that there are no internal batteries.

Overall features and functions

Considering that these OBD2 diagnostic tools fall in different price ranges, we should expect to see many differences in their features and functions.

The NT201 OBDII scan tool falls in the lowest class offering the basic functionality that you’d need. You can grab all the ECU data and see how the engine is working and if there are any error codes. If there are, you can erase them. In addition to that, you can do I/M readiness, EVAP, and O2 sensor tests. There is also an option to view live data and record it to review it later. As usual, a free frame option is available.

Next in the line is NT301, which provides the same functionality as the NT201 with a few extras like a built-in error code library and an option to export the scan results.

If you want to cover more systems in your car, the NT630 Plus is the OBD2 scan tool you’d like. It can do everything the other two can and scan the SAS, ABS, and SRS systems. Keep in mind that it cannot erase all codes in these systems. For the ones that it can erase, you first need to eliminate the problem. Unfortunately, it cannot check the transmission.

Extra features/functions

As for additional features, considering the price and category, you shouldn’t expect too much. The NT201 and NT301 offer the base basics, so no other extras there. The NT630 Plus has a few additional functions that enable you to check each ABS and airbag systems component. Additionally, you can also bleed the ABS through the NT630 Plus after a service.

On top of that, the software for the tools come in 3 language packs. The first one includes 5 languages: English, French, Spanish, German, and Italian. Also with 5 languages, the second pack has English, Portuguese, Hungarian, Dutch, and Swedish. The last one has English and Russian only.

The NT630 Plus is the only OBD2 scanner out of these three that comes with a carry pouch.

Supported protocols

Regarding the supported OBD2 protocols, there are no differences between all three FOXWELL diagnostic tools. They support all five OBD2 protocols: KWP2000, ISO9141, J1850 VPW, J1850 PWM and CAN.

Supported vehicle makes

This is where things get a bit confusing. FOXWELL claims that their OBDII scan tools work with any car manufacturer that is OBD2 compliant. That would usually include cars from 1996 and newer. Despite that, the list for some of them is not as extensive.

The NT301 supports US cars from 2001, European from 2004, French from 2006, Asian from 2006, and Chinese from 2011. This is still a relatively wide range of supported models, but there are still a few limitations. It will not work with Renault models from 2012 to 2018, no Clio 2 or Megane, Dacia Logan, VAZ, UAZ, and Lada. There are also some limitations to the Ssangyong brand.

Our recommendation is to reach out to FOXWELL and confirm that your car model is supported.

Software and updates

The software is baked into the OBD2 diagnostic tool itself, but you will need the FOXWELL application on your computer. While all 3 will work independently, you will need a Windows PC to upgrade or print the reports.

Speaking of upgrades, they get lifetime upgrades, and that goes through the Windows app as well.
