Six names come up whenever someone shops for an ELM327-compatible adapter. They are not six versions of one thing: each brand built its adapters around a different job, from a cheap Ford cable to a pro-grade Bluetooth unit.
Last updated September 2026Pick the OBDMonster if you want a low-cost Windows cable with a manual HS/MS-CAN switch for a Ford or Mazda. Pick Vgate if you want a well-supported budget brand with firmware updates, on USB or Bluetooth. Pick OBDLink if you want the fastest, most app-friendly hardware and will pay for it.
OBDMonster sells a USB cable, not a Bluetooth dongle. It plugs into the OBD2 port at one end and a Windows laptop at the other, with a small toggle switch on the body. That switch flips the adapter between the high-speed and medium-speed CAN buses Ford uses.
The board inside is labelled v1.5, the clone firmware Ford owners have favoured for years. The USB side runs through a WCH CH340T chip, so Windows needs the CH340 driver installed before the cable is plugged in. After that it shows up as a COM port that software can open.
There is also an auto-switching version, which saves you reaching under the dash mid-session. Either way it is a Windows-only tool; phones and Macs are out. Toggle-switch and electronic-switch FORScan cables differ mainly in how many buses they reach at once.
| Brand | What it makes | Chip and firmware | Best for |
|---|---|---|---|
| OBDMonster | Switched ELM327 USB cables for Windows | v1.5-labelled clone board, CH340 USB chip | Cheap Ford and Mazda module work |
| Vgate | iCar (Bluetooth, BLE, Wi-Fi) and vLinker (BLE, USB) lines | Own firmware; vLinker speaks ELM327, ELM329 and STN commands | Budget buyers who want updates and support |
| OBDLink | MX+, CX, LX (Bluetooth) and EX (USB) | Own STN-family processor with ELM327 compatibility | Heavy FORScan, BimmerCode and live-data users |
| Veepeak | OBDCheck BLE and BLE+ adapters | Branded ELM327-compatible | Simple phone diagnostics on iPhone or Android |
| Carista | The Carista app, plus its own adapter | Proprietary adapter; app also supports a short list of others | App-led coding on VW, BMW, Toyota and more |
| BAFX | Classic Bluetooth OBD2 reader | ELM327-compatible, classic Bluetooth | Android and Windows users only |
| ANCEL, Foxwell | Handheld scanners with their own screen | Not ELM327 adapters | Owners who want a tool with no phone |
Chip and firmware details come from each maker's published specifications. Carista's supported-adapter list changes, so check the app's own list before buying.
Vgate covers more ground than any other ELM327 brand. Its iCar range handles everyday phone diagnostics; its vLinker range adds the protocols and speed that coding apps need. The common thread is firmware that Vgate keeps updating.
The vLinker models accept ELM327, ELM329 and STN command sets, which is why coding apps treat them almost like premium hardware. The sleep current on most models sits around 3 mA, low enough to leave plugged in.
OBDLink adapters cost several times more than a clone. The difference starts with the chip: OBDLink uses its own STN-family processor, which understands the ELM327 command set and adds faster, more capable commands of its own. Apps that know about it can pull data far quicker.
Each model targets a job rather than a price point:
All of them add battery-drain protection and firmware updates. The EX claims up to 20 times the throughput of toggle-switch adapters, which matters when FORScan reads large module configurations.
Whether that is worth it depends on the job. For reading a check-engine code once a year, no. For regular FORScan programming or BimmerCode sessions on an expensive car, a dropped connection mid-write is the costlier risk. OBDLink also publishes a troubleshooting guide for checking vehicle compatibility before you buy.
The Vgate iCar2 BLE 4.0 connects to iPhone and Android without pairing in phone settings, sleeps at around 3 mA after 30 minutes idle, and works with Car Scanner, OBD Auto Doctor and Torque on Android. It is the plain, low-cost entry to Vgate's range.
Check it outCarista is an app before it is hardware. It reads and codes features on brands such as VW, Audi, BMW and Toyota, and it sells its own adapter to go with it. The app also works with a short list of third-party adapters; the OBDLink MX+ and Vgate vLinker FD+ both name Carista as supported.
That makes 'ELM327 Carista' a narrow search. A random clone is unlikely to work, and even a good branded adapter may not be on Carista's list. Check the app's supported hardware first.
Veepeak takes the opposite approach: plain, dependable BLE adapters with no app of their own. The OBDCheck BLE and BLE+ work with Car Scanner, Torque on Android, OBD Fusion, BimmerCode and BimmerLink. Two limits to know:
BAFX earned its name with a classic Bluetooth reader that pairs with Android phones and Windows laptops. Classic Bluetooth means no iPhone support, which is the main reason BLE adapters from Veepeak and Vgate took over as the default choice for mixed households.

Search for a Foxwell or ANCEL ELM327 and you will mostly find handheld scanners. They have their own screen and buttons and plug straight into the OBD2 port with a cable. No phone, no app, no pairing.
That is a real advantage for some drivers. A handheld like the ANCEL AD310 reads and clears engine codes, shows freeze-frame data and checks emissions readiness in seconds. It also lives happily in a glovebox for years, and it needs no phone battery or app update on the day the light comes on.
ANCEL also sells Bluetooth units. Before buying one for third-party apps, look for the words 'ELM327 compatible' in its specifications; many are designed for ANCEL's own app only. The same check applies to any Bluetooth scanner sold under a tool brand rather than an adapter brand.
Most of what an adapter adds over a handheld comes from ELM327 apps such as Car Scanner, Torque Pro and OBD Fusion.
It is the same switched ELM327 cable type that FORScan supports, with a manual MS/HS-CAN toggle. It names ELMconfig, FoCCCus and FF2, and needs the CH340 driver on Windows.
Only the BLE 4.0 version. The classic Bluetooth iCar2 pairs with Android and Windows only.
Rarely. Carista supports its own adapter and a short list of others, such as the OBDLink MX+ and Vgate vLinker FD+. Check the app's current list first.
Not in the adapter sense. Foxwell's tools are standalone scanners with their own screen. They do not work with Torque, Car Scanner or FORScan.
For FORScan programming or regular coding, often yes: faster data and fewer dropouts. For reading codes and live data on a phone, Vgate does the job for far less.
Not at all. The BAFX reader uses classic Bluetooth, which pairs with Android and Windows but not with an iPhone.
These are standalone code readers and app-locked scanners, not ELM327 adapters. They work alone or with their own app, which suits drivers who never want to choose software.
