What an ELM327 is, its versions and which to buy
The small adapter that turns your phone into a fault-code reader. What is behind the name, why almost all of them are clones and which one suits you.
Wi-Fi adapter · Vgate brand
Vgate Wi-Fi OBD2 adapter for iPhone, Android and Windows. It goes to sleep by itself when idle so it does not drain the car battery.
€23.37 VAT included · Satkit price checked on 7 October 2026
Prices incl. VAT checked on 7 October 2026; they may change.
It does the same job as a generic ELM327 Wi-Fi, but it is made by Vgate, a brand that publishes the full list of OBD2 protocols it supports, and it goes to sleep by itself when the car is parked.
It reads and clears engine fault codes (including manufacturer-specific ones), turns off the warning light and shows live data: boost, temperature, engine load, O2 sensors, fuel use... With apps that support it, it also logs data and draws charts.
While connected
Like any Wi-Fi adapter, it takes over the phone's Wi-Fi: while you use it, the phone has no internet over Wi-Fi.
