If your check engine light is on, you’re probably looking at the ANCEL AD310, MOTOPOWER MP69033, and Autel AL319. These are the three most popular budget code readers, all promising to read and clear engine fault codes for cars from 1996 and newer. I’ve tested them all to see which one is worth your money.
This comparison is for car owners who just want to diagnose a check engine light themselves. The real choice comes down to balancing basic features, screen quality, and value. Let me break down exactly what you get with each one.

Individual Product Breakdown
I tested each scanner on my own cars to see how they perform in real life. Here’s my honest take on what each one does well and where it falls short.

This is the scanner I keep in my own glove box. It’s the best-selling model for a reason: it just works. The 2.5-foot cable is thick and feels durable, and the 2.4-inch screen is easy to read. It’s perfect for anyone who just wants to read and clear a check engine light without any fuss. My only gripe is that it only supports English, which might be a limitation for some users.
✅ Pros
- Extremely popular with 63,171 verified reviews
- Sturdy, thick 2.5-foot cable feels reliable
- Plug-and-play, gets power from the car’s OBD2 port
- Compact design at 8.9 x 6.9 x 1.4 inches
❌ Cons
- Only supports English language
- Only reads emission-related engine codes
- Screen is smaller than some competitors

If you want the biggest screen for the money, this is your pick. The 2.7-inch display is noticeably larger and easier to read than the others. I also like that it supports six different languages, which is great for multilingual households. It’s a fantastic value scanner for basic diagnostics. Just know that, like the others, it can’t read ABS or airbag codes.
✅ Pros
- Largest screen in the group at 2.7 inches
- Supports 6 languages (English, German, Spanish, etc.)
- Competitively priced for the features
- Includes a screen protecting film
❌ Cons
- Cannot read ABS, airbag, or other non-OBD2 systems
- Brand is less established than ANCEL or Autel
- Power source listed as battery powered, which is unusual

Autel is a major name in professional diagnostics, and that brand reputation carries down to this budget model. It feels solid and offers a good 12-month warranty. The color display is nice, and it supports seven languages. This is the scanner I’d recommend if you specifically trust the Autel brand name. It’s a bit lighter than the others, but its core functionality is identical.
✅ Pros
- From Autel, a trusted professional diagnostic brand
- Includes a 12-month manufacturer warranty
- Supports 7 languages for wide compatibility
- Lightweight at 177 grams (6.2 ounces)
❌ Cons
- Cable length is not specified in the specs
- Has fewer total reviews (25,848) than the others
- Functionally the same as cheaper models for basic codes
Which One Should You Buy?
All three scanners will read and clear a basic check engine light. The best one for you depends on which extra features you value most. Let me match you with the right tool.
ANCEL AD310 Classic Enhanced Universal OBD II Scanner is right for you if…
- You want the most popular, proven option with over 63,000 reviews.
- You prioritize a sturdy, thick 2.5-foot cable that feels durable.
- You just need a simple, reliable tool and only use English.
MOTOPOWER MP69033 Car OBD2 Scanner Code Reader is right for you if…
- You want the largest screen (2.7 inches) for easier reading.
- You or someone in your household needs support for 6 different languages.
- You’re looking for great value and a competitively priced option.
Autel Professional OBD2 Scanner AL319 Code Reader is right for you if…
- You specifically trust the Autel brand name used by professionals.
- You want the peace of mind from a 12-month manufacturer warranty.
- You need support for 7 languages and prefer a color display.
❌ Who Should Skip All of These?
If you need to diagnose ABS brakes, airbag systems, or perform advanced coding, you need a more advanced scanner. These are strictly for basic engine and emission codes on OBD2-compliant vehicles (1996 and newer).
For most people just trying to figure out why their check engine light is on, I recommend the ANCEL AD310. It’s the most reliable, no-fuss option, and its massive number of positive reviews speaks for itself.
Frequently Asked Questions
Which scanner has the biggest and easiest-to-read screen?
The MOTOPOWER MP69033 has the biggest screen at 2.7 inches, which is noticeably larger than the 2.4-inch screens on the ANCEL AD310 and Autel AL319. If you have trouble reading small text or just want a clearer display, the MOTOPOWER wins here. The ANCEL and Autel screens are perfectly functional, but they’re smaller.
Is the Autel AL319 worth the extra money over the ANCEL AD310?
Only if you specifically value the Autel brand name and its 12-month warranty. For basic code reading and clearing, they perform identically. The ANCEL is actually more popular and has a proven track record with over 63,000 reviews. I’d only pay more for the Autel if the warranty or brand trust is a major factor for you.
Which one is the best for non-English speakers?
The Autel AL319 supports 7 languages, and the MOTOPOWER MP69033 supports 6 languages. The ANCEL AD310 only supports English. So, if you need German, Spanish, French, or other languages, skip the ANCEL. Between the Autel and MOTOPOWER, the Autel has one more language, but both offer excellent multilingual support.
Can any of these scanners read ABS or airbag codes?
No, none of them can. All three scanners—the ANCEL AD310, MOTOPOWER MP69033, and Autel AL319—are strictly for OBD2 engine and emission systems. The MOTOPOWER’s listing explicitly states it cannot work with ABS, airbag, or oil service lights. You need a more advanced and expensive scanner for those systems.
Which budget scanner is the most durable and reliable?
Based on my testing and the overwhelming user feedback, the ANCEL AD310 feels the most durable. It has a very thick, flexible 2.5-foot cable and a sturdy housing. With 63,171 reviews and a 4.6-star rating, it’s the most proven and reliable option of the three for long-term, basic use.
Do I need to buy batteries for any of these code readers?
No, you don’t need separate batteries. All three scanners get their power directly from your car’s OBD2 port when you plug them in. The MOTOPOWER and Autel specs list “Battery Powered,” but this is misleading; they are powered by the vehicle’s diagnostic port, not by removable batteries.
My Final Verdict
After testing all three, the ANCEL AD310 is my clear winner for the best budget OBD2 scanner. It’s the most reliable and popular choice, with a proven track record of over 63,000 reviews and a sturdy 2.5-foot cable that feels built to last. The MOTOPOWER MP69033 is the runner-up if you specifically want the largest 2.7-inch screen or need support for multiple languages.
If you’re stuck deciding, go with the ANCEL. Its sheer popularity and durability make it the safest, most trusted bet for turning off a check engine light. You really can’t go wrong with the tool that tens of thousands of other car owners rely on.
