Autel MaxiCheck MX808S

Buy the Autel MaxiCheck MX808S if you want confirmed bidirectional control and ECU coding on a Wi-Fi tablet, and you’re getting a genuinely competitive price for it. Skip it if you’re paying a premium for this exact tool over its MaxiCOM-badged twin without checking both listings first, more on that below.

The short version: Autel’s own official product page confirms both bidirectional active tests and “Coding and Adaptations,” meaning ECU coding is real here, not just implied by category. The more interesting finding, backed by independent retailers and Amazon’s own listing language, is that the MX808S appears to be the same underlying hardware as the cheaper MaxiCOM MK808Z, sold under Autel’s MaxiCheck badge at a real price premium.

What the MX808S Actually Does

Autel’s own technical page confirms a 7-inch LCD capacitive touchscreen at 1024×600 resolution, Android 11 running on a Rockchip RK3566 processor (1.8GHz Cortex-A55), 4GB RAM and 64GB storage, and a 3.7V/5000mAh battery rated for roughly 7 hours of continuous use. Connectivity is Wi-Fi only, 2.4 and 5GHz, with Mini USB, USB 2.0, HDMI Type A, and a Micro SD slot, there’s no Bluetooth radio and no CAN-FD/DoIP protocol support listed anywhere on the page.

Autel’s page confirms the MX808S reads and erases codes for all available systems and displays live data in text, graph, or analog form. Bidirectional testing is described directly: the tool can “perform bi-directional Active Tests,” and separately, the same page states it can “perform Coding and Adaptations,” Autel’s standard phrasing for confirmed ECU coding elsewhere in its lineup. The 28+ reset service functions Autel documents include oil reset, EPB service, ABS auto bleed, SAS calibration, DPF regeneration, injector reset, and service mileage/interval reset. Vehicle coverage spans 80+ makes and models, 1996 and newer, with AutoVIN identification. The tool is also compatible with Autel’s Videoscope accessory, and supports 10 named communication protocols. Box contents per Autel’s listing: the MX808S main unit, a USB power adapter, two USB cables, a quick reference guide, a printed user manual, and a carrying case.

What Amazon Says vs. What Autel Confirms

Amazon’s listing for the MX808S is titled, in part, “2026 US Ver. of MaxiCOM MK808S MK808Z,” Amazon itself describing this MaxiCheck-badged tool as a version of the MaxiCOM MK808 family. [Amazon] That framing lines up with what independent retailers report separately: multiple third-party sellers describe the MX808 and MK808 as sharing the same Rockchip RK3566 processor, 4GB/64GB memory, Android 11 build, and 7-inch 1024×600 screen, with the practical differences coming down to sales channel, MK808 sold online, MX808 through offline/retail channels, and cosmetic branding rather than capability. Autel’s own official pages for both models use near-identical spec and capability language, including the same “perform Coding and Adaptations” phrase. [Autel] [Autel technical] Neither official Autel page states the equivalence outright, but the pattern across manufacturer specs, independent retailers, and Amazon’s own listing title is consistent enough to treat as a real finding, not a coincidence.

The MX808S carries a real price premium over the MK808Z for what looks like the same hardware: roughly $449 on Amazon versus roughly $379 for the MK808Z, and $479 versus a comparable listing on Autel’s own store. [Amazon] [Autel] If the hardware genuinely is shared, that roughly $70 gap is a channel/branding premium, not a capability one, worth confirming directly with Autel before paying it.

Separately, Amazon’s listing also claims “3,000+ Active Test” and vehicle coverage of “200+ Brands,” neither figure matches Autel’s own MX808S page, which describes bidirectional testing qualitatively rather than by a specific count, and states 80+ car makes and models, not 200+. [Amazon] [Autel] Treat both as unverified marketing figures, the confirmed vehicle-coverage number from Autel’s own documentation is 80+, not 200+.

What this means for you: bidirectional control and ECU coding are both confirmed directly on Autel’s own MX808S page, safe to rely on. The “3,000+” active-test figure and “200+ Brands” claim are Amazon-only and don’t match Autel’s own numbers. And if you’re deciding between the MX808S and the MK808Z, verify current pricing on both, they appear to be the same tool under different Autel family names.

Same Hardware, Different Badge and Price

This is the same pattern SCG’s independent research on the MaxiCOM MK808Z turned up from the other direction: identical processor, memory, screen resolution, and reset-function count across the two official Autel pages, identical “perform Coding and Adaptations” language, and Amazon’s own MX808S listing title directly calling it a version of the MK808 family. The practical read for a buyer is straightforward, if you don’t have a specific reason to prefer the MaxiCheck badge, checking the MK808Z’s current price before buying the MX808S is a reasonable step, the capability set on both official Autel pages is the same as far as this research could confirm.

Where the MX808S Sits in Autel’s Own Lineup

Within Autel’s Wi-Fi-only, bidirectional-and-coding tier, the MX808S sits at a price premium over its MaxiCOM twin, the MK808Z, for what the available evidence suggests is the same hardware. If TPMS sensor programming matters to your work, the MaxiCheck MX808S-TS adds that at a further price step up, per its model naming and Autel’s own TS-variant convention, while the core bidirectional and coding capability confirmed here should carry over. For newer CAN-FD/DoIP vehicles or a larger 40+ service-function set, the MaxiCOM MK900-BT is the confirmed step up, at a meaningfully higher price, with Bluetooth added and Wi-Fi dropped.

Who This Scanner Actually Fits

The MX808S fits a shop or serious DIYer who wants Autel’s confirmed bidirectional control and ECU coding on a Wi-Fi tablet, and who’s comparison-shopped it against the MK808Z before paying whatever the current price gap between the two happens to be. It’s a weaker fit if TPMS work, Bluetooth, or newer-protocol support is part of the job, none of those are confirmed on this model’s own page.

Important Limitations

No Bluetooth, this is a Wi-Fi-only tool. No CAN-FD or DoIP support, and no TPMS-specific functions documented on Autel’s own page. The “3,000+ Active Test” and “200+ Brands” figures on Amazon’s listing don’t match Autel’s own documented numbers (qualitative bidirectional description; 80+ makes). And, per the finding above, this tool appears to share hardware with the cheaper MaxiCOM MK808Z, compare current pricing on both before buying.

Choose It, Skip It, or Consider Something Else

Choose the MX808S if you want Autel-confirmed bidirectional control and ECU coding on a Wi-Fi tablet, and its current price is competitive against the MK808Z.

Skip it if the MK808Z is priced lower for what looks like the same hardware, or if TPMS work, Bluetooth, or newer-protocol support is part of your job.

Consider the MaxiCOM MK808Z instead if price is the deciding factor. It’s confirmed for the same bidirectional control and ECU coding, on what the available evidence suggests is the same underlying hardware, typically at a lower price.

Our Verdict

The MX808S delivers exactly what Autel’s own page confirms, bidirectional control and ECU coding on a Wi-Fi tablet with a broad 28+ service-function set. The finding worth acting on before you buy is the apparent hardware overlap with the cheaper MaxiCOM MK808Z, sold under a different Autel family name at a real price premium, compare both current listings rather than assuming the MaxiCheck badge buys you something the MaxiCOM version doesn’t.

Frequently Asked Questions

Does the MX808S support ECU coding?

Yes. Autel’s own product page states “perform Coding and Adaptations” directly in its capability description, the same phrasing Autel uses to confirm ECU coding elsewhere in its lineup.

Is the MX808S the same hardware as the MaxiCOM MK808Z?

The evidence points that way: identical processor, memory, screen, and reset-function count on their respective official Autel pages, and Amazon’s own MX808S listing title describes it as a “US Ver. of MaxiCOM MK808S MK808Z.” Neither official Autel page states the equivalence outright, so treat it as a strong, evidence-based pattern, and compare current pricing on both before buying either.

Does the MX808S include TPMS functions?

Not confirmed. Autel’s own page doesn’t mention TPMS-specific functions for this model. If you need TPMS diagnostics and sensor programming, consider the MX808S-TS instead.

Is the MX808S compatible with my vehicle?

Autel documents 80+ makes and models, 1996 and newer; Amazon’s “200+ Brands” claim isn’t confirmed by Autel’s own page. Run your specific year, make, and model through the Finder to confirm before buying.
