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.
It's a misconception that whatever works for Torque App should also work for Dr. Prius, the reality is, to get to the battery specific information, the OBD2 adapter must have the ability to "set message header" to a different ECU address, while other generic Apps only targeting the main ECU to retrieve very basic vehicle information like speed, rpm, coolant temperature.. etc. So with that, I decided to buy all the cheap clone adapters and see for myself, you, my friend, just sit back and enjoy the show.
PS: Most of the adapters are for Android only, iOS users please jump to the bottom of the page.

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.
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.
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.
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.
This adapter comes with a nice acrylic case and instruction, it almost passes the test...
My first impression with this adapter is pretty good, it feels like this manufacturer/distributor spent time in branding and packaging, it works for most of the part but unfortunately, it has this weird bug that preventing some data from being retrieved consistently.
Note: This adapter can work with Dr. Prius but is missing DTC error code data, people actually give me one-star reviews for this reason...
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
Update 07/11/2018 - After a couple of one-star user reviews, I found that even a dual-layer PCB could be a bad clone, at this time I don't want to approve any OBD2 adapter in this form factor, it feels like someone from the Chinese factories is watching this post and changing their strategy to counter back, not cool, not recommend and buy at your own risk!
Update 06/09/2018 - Thanks to our friend Alexandr from Belarus, we actually found a good clone on AliExpress that is cheap and works well (as of 6/8/2018), be sure to pick the BLUE or WHITE adapter NOT the black with MINI on it. Please be aware that this seller recently swaps the black adapter with a bad clone that doesn't work at all, NOT COOL!
AliExpress OBD2 adapter for Android
If you believe expensive items are always good, think again..
I've received 50/50 praises/complaints about this OBDLink adapter that I had to purchase myself despite the expensive price.
Well, turns out this is a really fast adapter but all the good things pretty much stop there. 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. Also, I found it frustrating to pair it with Android devices, I think you have to click the connect button either at the right timing or with the right duration to make it discoverable by your Android devices, overall, I would not recommend this fast adapter to users.

An adapter that you can trust!
I got this PanLong OBD2 adapter from Amazon thinking I could return it anytime, and surprisingly that never happened in the past two years. This adapter is the work horse of all my developing and testing efforts.
Open up the case and see for yourself how beefy it is compared to any other clone mini, however their new adapter in red color is defective and won't work for Dr. Prius App or Hybrid Assistant App.
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.
Their WiFi adapter is only an “ok,” due to the fact the on/off button is confusing to use
