Auxiliary Footwell Outlet - Phone Adaptor

[jamesfielding]

Morning all,

Can someone smarter than me please explain what I’m doing wrong or point me in the right direction with regards to kit to order.

I’m trying to use drivers side auxiliary outlet as phone charger. Current setup which doesn’t work:
- 12V 10A supply via INT2 switch -> DCDC converter (down to 5V3A) -> USB C adaptor -> USB C Cable up to wireless charger on dashboard.

If I use the 12v on the cigarette adaptor they provided it works and measuring the voltage shows I have 5V DC out of my transformer. Does a phone charger look for anything else before powering up?

TIA

Hi James. I’ve used the auxiliary outlet from IN2 switch and connected usb sockets. I presume the dc converter is within the sockets as the back of the sockets connects directly to the to 12 v supply. Are you adding in an extra dc to dc converter ?

I normally run two USB sockets, one with the newer quick charge 3.0 (with C and A type sockets) and one of the older types (1 amp and 2.1 amps). By having a mixture I can charge almost any phone or device. Sometimes phones or devices can be picky which USB they will work with.

Example of newer USB socket:

USB & Dual USB-C Car Socket

Add fast charging to your car with 1 USB-A and 2 USB-C car sockets. Includes rubber cap and quick-charge support up to 45W. Shop Defender upgrades at MUD.

Older style socket:

USB & Cigar 12v auxiliary sockets

Twin USB & Cigar 12v auxiliary socket Technical specs Material:ABS Heat Resisting Plastic Voltage:12-24V Colour:Black USB Parameters: 5V 2.1A and 5V 1A 12v Cigar socket **Do not connect the Socket to a power supply over 24V** Package Included: 1 Piece USB Cigarette Lighter Socket + Plate + Lid...

Take the cig socket out and put in the newer USB socket and connect to INT2. It should work, mine do.

USB sockets can often be easily moved around into another panel or housing like you see in @Logsplitter's image above.

Many of switches seen on 4X4s are Carling type switches (now owned by Littelfuse) also called rocker switches. UK sources of these switches include:

2. MUD Stuff here; and
3. 12 VOLT PLANET here.

12v Planet in the U.K. are a great place for everything 12v inc solar charging. They are my main port of call for accessories wiring.

Thanks everyone.

Yes @Logsplitter I’ve got a secondary adaptor inline as I was trying to avoid having to have a cigarette lighter type thing going on.

 

[Logsplitter]

I’ve never used one of those adapters so can’t help you there.

There are quite neat surface mount solutions available but not sure on quality although Farrell are pretty reliable.

My setup is bulkier but quality components. If I could find a quality slimline alternative I may change it.

I purchased one of these slim line made in China outlets but have never used it as I really don’t trust the components and quality !

True. This is the Chinese one I’m using although I did measure the voltage and I was getting 5V from it. Perhaps you’re both right and I should try something from Farnell or other more reputable retailers

I would definitely buy from a reputable source rather than some unbranded thing from Amazon. Amazon can be a source of some good deals if you’re buying a well known brand such as blue-sea.
12v planet have everything you need

Question about this setup:
- are you relying on your device being able to handle 12V or is there a small transformer in the back of this unit taking it down to 5V?
