Buy the Koogold EC-103 2-in-1 Wireless & Mirroring Adapter for $99.99 from Amazon US and the Koogold EC-102 compact 2-in-1 Adapter for $99.99 from Amazon US
Wireless CarPlay adapters are nothing new, but most of them focus on doing just one thing: removing the cable for Apple CarPlay. The Koogold 2-in-1 adapter takes a different approach by combining wireless CarPlay with full device screen mirroring over a wired connection. That opens the door to video streaming, gaming and app mirroring directly from your phone onto your car’s display.
In this review, I’ve tested the Koogold adapter in real driving conditions using both iPhone and Android to see how well it performs, where it excels, and where the compromises are.
What the Koogold Adapter Does
At its core, this adapter converts your existing wired CarPlay system into wireless CarPlay. Alongside that, it adds a wired screen mirroring function that allows you to mirror your phone’s display onto the car screen. That means apps like YouTube, Netflix, Twitch, cloud gaming services and even mobile games can be shown on your car’s infotainment display.
Instead of relying on an internal processor like an AI box, all the heavy lifting is done by your phone. This makes the adapter simpler, cheaper, and often more powerful than standalone Android boxes. For some, this kind of solution can be better than an AI Box could ever be! Just as long as it’s done right.
Installation and Setup
Setup is extremely straightforward. You plug the shortest of the adapter’s three tethered cables into your car’s CarPlay USB port, optionally connect the power passthrough cable, and then connect your phone either wirelessly (for CarPlay) or via USB-C for mirroring.
Boot time was impressive, averaging around 7.1 seconds into its simplified two function main menu. From here you simple either connect via Bluetooth from your iPhone for a wireless CarPlay connection, or pick up the cable and the menu will launch into mirroring mode. A small (yet awkwardly placed) back button is available on touch at the top left corner of the screen to return to the main menu should you wish to switch between each function. This button needs some work because it doesn’t always take you back to the main menu. Instead it just takes you to your car system screen instead.
Wireless CarPlay Performance
Wireless CarPlay works well overall. Touch responsiveness is good, audio quality is clean, and steering wheel controls function as expected. After a 106 version firmware update, visual sharpness in the wireless stream improved noticeably, although it’s still slightly softer and bright than native wired CarPlay.
Being software emulated, there is no instrument cluster or HUD pass-through from Apple or Google Maps on my Cupra Born. Music didn’t resume after calling or listening to messages in version 104, but this was now fixed in version 106.
For most users, though, the wireless CarPlay experience is stable, fast, and convenient. It just isn’t hitting the same smoothness as more dedicated hardware emulated adapters. But this is at the compromise of having the mirroring ability alongside it.
Screen Mirroring on iPhone and Android
Mirroring is where this adapter becomes interesting. When connected via cable, both iPhone and Android devices mirror smoothly onto the car’s display, with low latency, good lip sync, and stable performance.
You can adjust aspect ratios, via a button on the top right, to better fit different screen shapes, which helps with vertical or ultra-wide displays. However, there is no touch pass-through as seen on the Ottocast Mirror Touch adapter, meaning all interaction must be done on the phone itself.
Video streaming apps such as Netflix and YouTube all worked reliably, with better quality stream when connected to home Wi-Fi than using mobile data. But this is a limitation of the apps used than a fault of the adapter. Locally stored or downloaded videos on your phone would offer a much sharper workaround for this limitation.
The best thing with this solution over an AI Box is that both your internet and apps are already signed in and available on your phone. There’s no need to connect to hotspots, or download your common suite of used apps again, or sign into all or existing streaming apps or services. No, it’s all there ready to rock by just simply plugging in the mirroring cable.
The only caveat is your mirroring your vertical orientated phone screen on a (most likely) landscape car display. So unless the app you’re mirroring can utilise a landscape mode (such as watching video or landscape gaming), then the content is going to be not that much smaller than your phone screen. So in summary, watching video or playing video games is the best use case for this adapter.
Gaming Performance
Gaming is surprisingly good whilst mirroring your phone to a larger display in the car. With a Bluetooth controller paired to your iOS or Android phone, you can play mobile titles like Asphalt, Call of Duty Mobile, and cloud gaming services such as Xbox Cloud or Luna.
Latency was low enough for racing and casual gaming, although fast-paced first-person shooters are not ideal. Still, compared to most AI boxes with weak GPUs, this setup performs far better.
Gaming doesn’t have to be from your phone either. You could connect any other type of USB-C device with DisplayPort ability. So devices like a Nintendo Switch or Steam Deck is possible. Even and iPad or laptop. Mirroring from a connected device from the back seat of the car is possible thanks to its 1.5m length of mirroring cable. You can go nuts over the possibilities.
Strengths and Weaknesses
The biggest strengths are flexibility, performance, and simplicity. You get wireless CarPlay plus mirroring without having to log into separate accounts or manage an Android AI Box.
The main limitations are the lack of touch interaction for mirrored content, no cluster or HUD support, and a few CarPlay quality quirks over much more dumber wireless adapters without mirroring capability.
There’s also the issue of having to keep your device display active and turned on to maintain a mirrored connection to the display. Thankfully battery life isn’t an issue with passthrough power being dealt with via the connected power cable, but you can’t sadly tuck your connected device away and use touch pads through. It’s almost like a second screen experience albeit mirrored in its content stream.
My Impressions
The Koogold 2-in-1 adapter is not a full AI box replacement, but it’s a powerful, and in some cases, cheaper, alternative for people who want wireless CarPlay plus screen mirroring, gaming, and video streaming powered by their own phone or connected USB-C DP device.
If you’re happy to control everything from your phone and don’t need touch passthrough on the car screen, this is a very compelling option — especially at its low price point of $99.99.
