Research-based comparison: We have not hands-on tested these code readers. This page uses first-party Autel and ANCEL documentation, current Amazon price snapshots, and our verified product briefs.
Quick Answer
The Autel AL319 and ANCEL AD310 are both low-cost, self-contained OBD-II readers for Check Engine diagnostics. Both have verified code read/clear, freeze-frame, live-data, and I/M-readiness functions. ANCEL’s verified documentation also explicitly lists EVAP testing and vehicle information, while Autel confirms generic and manufacturer-specific OBD-II code retrieval and live PCM data. At the snapshots used here, both were listed at $29.99, so the choice is mostly about documented feature details and brand preference—not a major price difference.

Where the Autel AL319 Fits
Autel identifies the AL319 as an OBDII/CAN code reader and confirms generic and manufacturer-specific OBD-II code retrieval, MIL/code clearing, freeze frame, live PCM data, and I/M readiness. Autel also states compatibility with most 1996-and-newer OBD-II/CAN vehicles.
That makes it a straightforward choice for engine/emissions diagnostics without phone apps or advanced module access.

Where the ANCEL AD310 Has a Slight Documentation Edge
ANCEL confirms the same basic OBD-II foundation—code read/erase, live data, freeze frame, and I/M readiness—but its first-party page also explicitly lists EVAP testing and vehicle information. It also states that the scanner is powered from the OBD-II connector and does not require batteries.
ANCEL publishes compatibility caveats as well, including a statement in the cited product page that hybrid/electric vehicles are not supported. That is a limitation worth checking if your vehicle falls into that category.

Which Is Better for a Check Engine Light?
For basic code retrieval and clearing, both qualify. Neither has a meaningful verified advantage simply for reading a typical engine/emissions DTC.
If you want the broader explicitly documented basic feature list, the AD310 has the edge in our source set because EVAP testing and vehicle information are directly confirmed. If you prefer Autel’s ecosystem and only need the core OBD-II functions, the AL319 remains a valid choice.
Neither Is for ABS, Airbags, or Active Tests
This is the most important buying boundary. These are entry-level OBD-II readers. Do not choose either one for ABS, SRS/airbag, full-system, or bidirectional diagnosis.
If your warning light is outside the engine/emissions system, read Basic Code Reader vs Full-System Scanner before buying.
Who Should Buy the Autel AL319?
- You want a simple Autel-branded OBD-II reader.
- You need codes, freeze frame, live PCM data, and readiness.
- You do not need enhanced modules or service functions.
Who Should Buy the ANCEL AD310?
- You want the same low-price tier with a slightly broader explicitly verified basic feature list.
- EVAP testing and vehicle information are useful to you.
- You understand ANCEL’s published compatibility caveats.

The Practical Takeaway
At an equal $29.99 snapshot price, the decision is close. The ANCEL AD310 has the stronger explicitly documented feature list in our verification, while the Autel AL319 covers the core OBD-II jobs most beginner buyers need. If your diagnostic requirements extend beyond Check Engine/emissions work, neither is the right tool tier.
