Nothing can be worse than waking up in the morning and seeing a one-star review from a user claiming my app isn’t working. Luckily my friends and loyal users help me identify that 90% of the problems are caused by bad clones out there flooding the market, those bad clones lure users with unbelievable low prices but the results never end well… at least for Dr. Prius App and other hybrid-specific Apps like Hybrid Assistant.

15.1. Mini Junk

This expensive adapter claims to support bluetooth 4.0 and all OBD protocols. Yeah right! this is another junk adapter that is being packaged in a tiny and beautiful space-grey semi-transparent case, however, it is far from usable and it does not have the ability to switch between ECUs, I’ve tried it on both iOS and Android devices with the same disappointing result. The only App that works for this adapter is called “Mini OBD II” App, it is nothing more than a proxy to the basic vehicle information.

15.2. No Name Junk

This no-name Junk is sharing the same packaging as the previous Mini Junk. It has a nice transparent blue finished, and it “looks like” it is able to switch between ECUs, however in the end it failed to retrieve any battery-related information from both Prius Gen2 and Gen3. Please browse away whenever you see this packaging, I believe they are from the same company that produces defective/un-tested products.

15.3. Mother of all Junks

This particularly cheap clone has dominated the market for many years and it’s absolutely disgusting, there is a real ELM327 version out there but with a more expensive/realistic price tag. Definitely one of the worst adapters, it doesn’t even support most of the basic OBD command from v1.2 all the way to v2.3, it might work with a few simple OBD apps but definitely not for Dr. Prius.

15.4. OBD2 mini with ON/OFF switch

This is a weird adapter that kind of works. This adapter with On/Off switch has a tendency to losing connection, on top of that it is missing info in every response (missing number of additional bytes at the beginning of each payload). I was able to make it work for Dr. Prius, however, I still do not recommend using this adapter.

15.5. Bait and switch Junks

You will find these packages on the internet everywhere, however only a handful of sellers are actually selling the good stuff, so please make sure you see double-layer PCB from the product pictures.

15.6. BlueDriver – expensive orphan

Even after spending $100 bucks, BlueDriver can only work with it own proprietary App using their own proprietary protocols (not ELM327 compatible).

15.7. Expensive adapters not always good – OBDLink LX and MX

The manufacturer claims to support both Android and iOS, however with iOS, it only supports classic Bluetooth and not BLE (Bluetooth Low Energy), unfortunately 99% of the iOS App only supports BLE, Dr. Prius App included.

15.8. Viecar for iOS and Android

Used to be Carista FIXD is another company selling the same adapter bondo their own App, the adapter works the same but at a much higher price.

15.9. Veepeak for iOS and Android

Great adapter at a good price Let’s start with their Bluetooth for Android, it’s basically the same as PanLong or any other beefy clone adapters selling at a great price, great deal! What really impress me is their Bluetooth BLE 4 adapter out-performing many adapters in terms of speed.

15.10. INFOCAR for iOS and Android

Popular OBD2 adapter on Amazon An user approved/suggested OBD2 adapter.

15.11. BAFX 34t5 Bluetooth (Android only)

Following are the popular OBD2 adapters that approved by many Dr. Prius users.

15.12. Expensive junk

This FIXD adapter cost $60 on Amazon and it is super slow and keep skipping records, although I made it to work for Dr. Prius App but I would not recommend it.
