My 2018, Carplay & Dual USB Mod

[Bogbody]

Wether a phone charges and runs AA depends on the phone.
My old Sammy S3 would last 2 and a bit hours on charge running "Here" scattynav, and then fail with "battery overheat". It would take ages to cool and re-start. So I tended to use it only for the last part of the journey.
My S7 runns AA without a problem - 6 hours connected the standard Astra usb all the way back from Devon and it was fine - not 100% charged - but fine (over 50% I think!!)
Thats the longest journey I do, so it suits my needs.

No...

My phone worked fine on the old "one USB, one AUX" module, but it would only charge at 500mA which was barely enough to keep the phone at the initial charge percentage. Some times it gained 1-2% on a 2 hour journey, some times it had lost more. Probably depending on whether i had done a lot of talking on the phone or not.

With the new module, i can charge the same phone at 1500mA which is more than adequate to actually charge the phone.

This is the exacy same experience most other persons in this thread that bought the dual USB module, so on a fairly modern phone the only problem with the original one was that the charge current was capped at 500mA which is not enough unless you dont do anything on your phone while it charges.

I usually do Android auto, stream music via my phone on AA, and make and receive calls and with that user pattern, the old one simply does not cut it charging wise.

The s3 was used in an old Signum - max charge 500mA. Course Here lit up the display - that old s3 used more power to light the screen than the charger could supply. No fast charge !!
If our Ebay matey re-surfaces with apapters at £21 I'll go for one

It arrived promptly about 3 weeks after order.
It fits and works. No GM branding tho.....
Fitting is easy but fiddling the connector into place is bit time consuming- I used an inspection mirror to help see. The connectors clip into place ... look carefully for the clips before forcing them off. They only need pressing gently to open.
Practice clipping them in before snaping the usb block into place so that you know how they feel and fit.

I have a 2016 1.4 turbo astra i have checked my usb ports today with ampere the arm rest one charges at 350-400ma . Interestingly the two rear ports charge at 1.4 amps . Why vauxhall could not do the same with the arm rest I don't know . After looking at the ports the rear ones have just power connections . I thought maybe someone with more know how would be able to see If extending the data carrying wires to the rear ports would work , it is not as straight forward as it sounds as the power connections on the rear ports are on different terminals the the arm rest so the data connection would need working out as to which terminals they connect to as well

It won’t work. The module itself is a USB hub, and the car doesn’t like a USB hub plugged into a USB hub. You would lose CarPlay and Android Play.

I looked at this when trying to get two ports working. I linked a post on the German equivalent site. It’s with a read as the tested all of this.

That would not work.

Just bite the bullet and buy, either an original usb part from vauxhall, and get one that is for a newer MY car, so it will have the 1½A charging or buy one of these dual USB sockets mentioned in this thread.

I got one of the dual USB ones from the seller, and it works just fine.

The rear seat charging ports will be on their own charging circuit, and you can not simply splice the data wires to them, or the power from them, to the armrest port.

The charging current is made by the USB part in the armrest, it is just fed, 12V and then it has an onboard PSU that will take the 12V to 5V
