Perfect for Samsung Galaxy Z Fold 3

For USB C Splitter for Android Auto / Apple Carplay

Kind and detailed guide on Seller's manual was so helpful for me.
Finally it works for my Samsung Galaxy Z Fold 3.
No more worry for battery during using Android Auto system on my Hyundai Sonata.

Great Product

For USB C Splitter for Android Auto / Apple Carplay

It works perfectly for a S22+. Used the powerline+ cables that were recommended and amazon basics USB data cable. Also, user a 55 watt car charger for the fast charging. Would recommend.

Doesn't work with any of my phones

For USB C Splitter for Android Auto / Apple Carplay

I purchased this to connect a Kenwood Android Auto head unit to my main phone (currently, Pixel 5 but I have a 6A as well). I can *only* get my Pixel 5 or 6A to come up as a USB device in the following circumstances.

- USB data connected *first*
- Power provided via USB-A to USB-C cable, not USB-PD

If I do things in this exact sequence, the USB data channel comes up. If I change the sequence by connecting power first, the USB data connection will not come up. If I try to use USB-PD (in any sequence) the USB data connection will not come up. My Kenwood DMX9720XDS head unit only brings up the USB data connection after it has booted (~10 seconds after it is powered on). Any power provided from a supply comes on immediately when the ignition is turned on, so the sequence won't work. USB-PD can't be used as I cannot get it working at all with USB data via the splitter on these phones.

The Pixel 5 will charge, and will charge at USB-PD rates, but will not make a USB data connection unless the power source is not USB-PD. It will also not bring up its USB data connection unless USB data is connected first or at the exact same time as the USB data connection.

I also tried on an Oppo A76. The Oppo worked reliably but only charged at 500mA even when connected to a USB-PD charger.

I can't recommend this product. I believe this setup needs to be an active circuit which performs negotiation on behalf of the phone and the USB data device (i.e., a head unit).

Great

For USB C Splitter for Android Auto / Apple Carplay

Works as advertised with a Galaxy S22U.
The cable quality really is important though.

No problems with customs for me (Germany).

Thank you for taking the time to develop such a niche Produkt.

Does exactly what I wanted and solved my problem

For USB C Splitter for Android Auto / Apple Carplay

I've owned a car with Android Auto for over a year, and have been constantly frustrated that it couldn't keep my Google Pixel 6a charged while using it. I was all ready to spend $100 for a wireless Android Auto adapter, but then this dongle came back into stock, so I figured I'd give it a try.

I purchased some fairly high-quality USB cables from Amazon, along with a new PD charger. After getting everything plugged in, I was happy to see both a stable connection to the car's head unit and that the phone was now fast charging. I've been testing it for the last few days, and so far have no complaints. The dongle is currently mounted to the underside of the dashboard in the console tray area where the USB and 12v ports are located. It's tiny, and easy to hide.

In an ideal install, I could imagine the car's USB port being disconnected, the PD charger and data ports connected up out of sight, and then a new USB C port being used in place of the car's original one. But just plugging it all in and using a bit of cable control and double-sided tape works just as well. The dongle's build quality is solid, and works as advertised.

Highly recommended!

It works

For USB C Splitter for Android Auto / Apple Carplay

It works great, but you need to use quality cables. If you don't then it will not work and some cables look like they are of quality but are not.

LOVE! Works great!!!

For USB C Splitter for Android Auto / Apple Carplay

This is a phenomenal product! It's a must have if you have android auto/apple carplay. Make sure you buy the types of cables recommended and you're golden.

Galaxy S9 cannot use rapid charge.

For USB C Splitter for Android Auto / Apple Carplay

I ordered this item august 5th. and I get 1st of September. but this seller contact to me and modify this shipment. i satisfied about communication with this seller. There is a micro-5 pin terminal and a usb-c port on one side, and a usb-c port on the side to connect a mobile phone to. If you want to know about terminal of this item.
I use Galaxy S9 but this item cannot support rapid charge. android auto works well, but rapid charge cannot work. if you use GALAXY S9, you can check my review. thank you.

Jean-Michael | June 14, 2022

Very happy with this product

For USB C Splitter for Android Auto / Apple Carplay

At the beginning the splitter did not work even if my micro usb wire had the data. but after communicating with the seller, he strongly suggested that I use Anker's power line cords on Amazon and voila everything works. i now have android auto and super fast charging. in my phone i can choose normal charge or fast charge. I also limited the maximum charge to 85% so I not overload the battery during long trips. I am very happy that it works and the seller was very nice. Work in VW gti 2016 and civic 2018 with a Samsung s21 ultra

Galaxy S22 + 2020 Lexus ES300h

For USB C Splitter for Android Auto / Apple Carplay

Works as advertised. It is a tiny product. Follow instructions correctly. I purchased amazon basics cable for the data. Anker powerline cables for power. And I purchased 30W PD Car Adapter. I have android auto + SUPER fast charging on S22. Now the issue is hiding the cables as Lexus put the android auto usb plug under a flip cover;poor design. If you need pictures send me a msg.

David | June 9, 2022

Works perfectly

For USB C Splitter for Android Auto / Apple Carplay

It just works as advertised although I'd wish to have power from the car through a diode so it'll also work when the ignition is off. My car disables all sockets as soon as the ignition is off. This is no show stopper at all but would be a nice addition.

I'll connect my charger to permanent instead now but this is something to keep in mind though.

All in all very happy with the solution. Shipping to Germany went crazy fast, although it's expensive, of course... but eh ;)

Reinhard | May 20, 2022

Works as advertised, but....

For USB C Splitter for Android Auto / Apple Carplay

... It doesn't charge with the full capacity of the fast charger.
It's more powerful then the android car plug only thou. So it does it jobs and avoids draining the battery.
I have tried that unit with Note10+, Note10, Galaxy S22+ successfully.

For now, more about the seller than the product

For USB C Splitter for Android Auto / Apple Carplay

I have a power-hungry phone (a Galaxy Note 10+, which is listed as compatible), and the car's native connecter is just not up to the task. More than once my phone has died during the day (due to a toddler who loves to play on Daddy's phone), and then was unavailable for GPS that evening. When a trip to the Renaissance Festival and a dead phone almost stranded my whole family, I decided I needed a fix.

A quick Google search brought me to Reddit, where this very device was being discussed. It seemed perfect! The answer to my conundrum! But they were out of stock. I placed myself on the waiting list and checked every day until it was available again. I ordered immediately.

The splitter itself arrived very quickly, but I also needed to buy some short cables so that my front seat wasn't a pile of spaghetti. The last one came in today, and with bated breath, I hooked it all up. No power, no connection to Android Auto... nothing. Imagine my disappointment. I tried different cables, made sure that the PD adapter could charge the phone on its own, made sure the Android Auto connection was working by itself. Everything seemed fine, until I tried to route through the splitter. (Splitter? It's really a combiner, isn't it?)

I was about to write an unkind review, or at least a frustrated one, when I decided that no, I really needed to give the seller/maker the chance to help without me badmouthing him in front of others. I had seen on reviews already that he was quick to respond and very helpful, so that seemed the most fair option. I tried very carefully to detail my issue, the hardware I had, and what steps I had taken to troubleshoot the issue, and even my own amateur theory on what was happening.

I didn't expect a response the same day. I would have been impressed with Mr. Koripalli if he had replied tomorrow, or the next day. Instead, I believe it took him... four hours?

I should admit my shame here: I work in IT, and have for a couple of decades. I'm used to troubleshooting, but I also know that I don't always think of everything to try, and that I have a tendency to bypass the basics and go right for the more complicated stuff. I thought the combined length of the two cables I was using was causing problems, since USB-C PD has a rather short max length specification. Mr. Koripalli very gently suggested a different, simpler solution while also pointing out, very kindly, that I had neglected to read the instructions that he had already provided. RTFM, and all that, but much nicer.

Please, please, if you buy one of these things, and you get no power going through it, take the cable going between the splitter and the power adapter, and flip it end-for-end. Swap the connectors that are in the splitter and the power adapter. I have a strong feeling it will work. Mine did, and I felt dumb.

I haven't had a chance to fully test this out yet, only having time to confirm that my phone was charging and that Android Auto recognized it and could play audio from it. The only reason I didn't rate the product as 5 stars is because I haven't had the opportunity to use it yet. If possible, I'll edit this review later, and if not, I'll just write another one.

If your phone is power hungry like mine, and you want to use Android Auto, buy this. Don't hesitate. Buy it. Now. Go.

Doesn't work most of the time

For USB C Splitter for Android Auto / Apple Carplay

This thing seems to be *extremely* picky about what kind of cables you use, what kind of phone you have, and what kind of vehicle you have. I have to admit that I have seen it work, but I'll be damned if I can figure out why or how to recreate that combination. How something that (theoretically) should be so simple can be so finicky is beyond my patience.

Response from Rohan Koripalli | Nov. 20, 2021
Hi Robert,

Thank you for your feedback. You're correct that the setup is very picky about cables and phones that are compatible. As I mentioned in the product description, many phones are incompatible due to not supporting USB PD or various software quirks. The most common problem people have when setting up is that the board passes through the power delivery connection from the charger to the phone. As a result the connection from the phone port of the board is not reversible and only works in one direction as mentioned in the instructions. This is not typical for USB C so although it seems random it's actually quite predictable. Considering you were able to get it working at least once I'm guessing that is your issue.

I'm more than happy to assist with any issues with your setup including replacing your unit if necessary. Please contact me with the details of your setup so I can help out.

Regards,
Rohan

Works intermittently

For USB C Splitter for Android Auto / Apple Carplay

Edit: firstly my apologies to the creator - he responded in the end and offered me a refund. I was in process of video recording the product not working, but typically it started to work! I used the same cables when it didn't work.

Today it didn't work when I plugged it in. After trial and error I believe that it is best to plug in the power cables first to the phone, and then when the phone is charging to connect the data cable. For me when I leave the power and data cable both plugged in to the unit and then connect the phone it fails. But the power first then the data works. Hope this helps others.

Pixel 6 Pro

For USB C Splitter for Android Auto / Apple Carplay

Just received this and it appears to work with fast charging on the Pixel 6 Pro. Phone indicates fast charging and battery increases as if it was plugged in to a USB C-PD charger. I don't have a USB monitor to actually verify amps being pulled, but I'm happy with it. I'm testing this with a 2020 Toyota Tacoma stock head unit.

Fantastic!

For USB C Splitter for Android Auto / Apple Carplay

This little device is a big help. Works as intended and the case looks good. I found some 6" cables on Amazon to limit the mess from the extra wiring. But, well worth it because my phone now charges reliably while using Android Auto. All 3 cables are from Cable Creations on Amazon. My phone is a OnePlus 8T+ and I drive a 2018 Chevy Equinox. Before, my phone would sometimes charge normally, sometimes slowly, and sometimes actually slowly lose power. So far it is working great. Not warp charging, but I'm just using whatever cigarette lighter adapter I already had. Thanks!

Great Product, Amazing Service

For USB C Splitter for Android Auto / Apple Carplay

I bought this to use with me Samsung Note 20 in my 2021 Mazda 3.

I at first had some difficulties getting it to work, I initially just thought I had a compatibility issue with either the car or phone. I contacted Rohan to let him know the Note 20 might not be compatible and he helped me troubleshoot the issue. We eventually came to the conclusion that the board might be faulty after I tried it with another phone and he sent a new board right out. I was able to get it working with the new board.

Amazing customer service and troubleshooting help, Rohan went above and beyond to help.

Now with the board working, I can say it does what it's supposed to do and its great to be able to have my phone charge fast while also using Android Auto.

Thanks again Rohan!

Finally fast charging

For USB C Splitter for Android Auto / Apple Carplay

25 watt charging is working with both my S20 FE and my wife's S21. I'm using a short Samsung usb c cable from the charger, and old Verizon usb c from the splitter, and a random micro usb that came with a flashlight. It didn't work the first time it was plugged in but turning over the usb c cable from the charger fixed it. I also bought the case which is nicely done in laser sintered nylon. The finish is nicer then anything I could print and I don't need to worry about it breaking down in the heat.

It works!

For USB C Splitter for Android Auto / Apple Carplay

I had a little issue with its temperament at first since not all cords were compatible so I had to rummage around the house for micro USB's and other cables. At first C to C cables didn't work for the power with my Anker cigarette lighter charger. Multiple A to C cables for the power worked until it didn't because it started telling me to check the cords I used so I switched back to C to C in hopes that it will work again (I honestly thought I broke it!). I had to take it inside the house and plugged it into my 45W and 65W USB C laptop chargers, and they worked just fine and charged my phone with the dongle. I returned to my car and after some fiddling... it just worked. I don't know what I did but it just worked. Android Auto and charging, finally. I'm not fiddling with those cords, haha!

I am so pleased I finally have a solution to the power charging problem I was having with my LG V20 and 2017 Sorrento when using Android Auto. Props to Rohan Koripalli for designing and building such a high quality device!

Took a while to ship out to Sydney. The case is a bit easy to crack but managed with some blue tack. I've got a Samsung S10e and it works great with an aftermarket Sony XAV-AX5000 head unit! can confirm that it fast charges while Android Auto is running.

Great product

For USB C Splitter for Android Auto / Apple Carplay

The product itself is smaller than I expected and the case was definitely worth the small upcharge for the peace of mind that it'll stay safe in my glove compartment. As long as you use the cables recommended by the seller, this product should not have any connectivity issues.

I originally purchased this for my LG G8 ThinQ but it doesn't work with my device. It works fine on my wife's Samsung Galaxy S10 though. The seller is awesome and very helpful and quick to respond. It's refreshing to have such an amazing experience with a seller that stands behind their product and provides this level of customer service. Thanks again!

Excellent product, but not for ALL phones

For USB C Splitter for Android Auto / Apple Carplay

Well-made product, and nice 3D printed housing. Works great for certain phones. May not work for ALL combinations of phones, chargers, and versions of Android.

Car: 2018 Subaru Impreza
Charger: Anker 42W PowerDrive Speed+ Duo, (w/ USB-A and USB-C PD ports)

Phone(s):
LG G7 ThinQ, Android 9, WORKS. Connects to Android Auto on USB-A power (regular charging) AND on USB-C (fast charging).
LG G8 ThinQ, Android 10, DOES NOT WORK. Only connects to Android Auto on USB-A power (says "charging" but actually slow discharging). No AA connection on USB-C (fast charging only, AA icon greyed out on Subaru screen). Changing USB Debugging mode settings had no effect.

USB Cables: All new Monoprice cables (A-to-C power, C-to-C power/phone, A-to-micro car/data)

The G7 and G8 both running the latest Android Auto (6.5.612134-release), with the same power settings. The issue may be with Android 10. (Android 9 has a separate Android Auto app, with its own shortcut, and seems to work fine.)

Works Great for MOST Phones!!!

The splitter works great on my 2018 Hyundai Kona Trend. But...

The only issue I have is that it does not work on my Asus Zenfone 6 (daily driver). Just can't get it to connect to the head unit in any car. Seems like just my luck lol! I did test 3 other phones though!

I can confirm that device works on the Essential PH-1 perfectly, works on the Asus Zenfone 3 perfectly and the Samsung S21 perfectly.

Amazing idea and excellent execution!

For USB C Splitter for Android Auto / Apple Carplay

Works great with an LG V60. Does exactly what is described, nice small board, I haven't gone out of my way to install it in my car yet, but it does work well. My head unit basically wouldn't charge my phone, simply "keep it from dying" and now I can use my fast charger when I need to! The only downside has nothing to do with the device, and just that adding 2 more cables and more connectors and points of failure to a system like that increases like likelihood that something can not work correctly.
