Introduction: USB Power Socket in the Car

Picture of USB Power Socket in the Car

Though there is always an option of 12 volt adapters for vehicles to be used in cigarette lighter for charging mobiles n tabs but just for a better look I decided to create a USB power socket for my car.

Step 1: Disassemble USB 12V Car Charger for Mobile.

Picture of Disassemble USB 12V Car Charger for Mobile.

I disassembled a 12V USB car charger with 1amp and 2.1amp usb ports and removed the circuit board from the plastic casing.

Step 2: Preparing the Cover

Then I cut a piece of plastic equal to the size of the port where this socket has to be installed in the car. Cut a square box in the cover according to the size of USB port and a hole for led light. I applied carbon fibre vinyl sheet for refined look.

Step 3: Installation of Circuit Behind the Cover

Then I fixed the circuit board behind the cover using metal mender after which it gave this look.

Step 4: Wiring

Then I soldered the wires to the circuit board. These wires are to be connected to cigarette lighter for power. I also installed metal clips on the back of cover to fix it in the car.

Step 5: Final Look Before Installation

Step 6: Installation

After that I fixed USB power socket into the console and here is the final out come.

Or you could save yourself all the work, and just install one that is designed for the purpose in mind.

Hey, thanks for the great idea. I am putting this set up in a classic mgb, shhhh sacrilege yes I know... Quit question, the prongs that stick out from either side of my circuit, can I hook up my ground wire directly to them or should it be integrated with the circuit some how. Likewise, can my positive wire be hooked straight to the back? what happened to your prongs?

rehanch (author)SUBYRIDA252015-04-12

yes i also hooked the wires directly to the prongs

Parts list, please.

David97 (author)jockelleis2015-03-02

I would use any USB car charger you could probably find one at a tech store or suermarker. really anywhere.

David97 (author)David972015-03-02

For the connector he used a tamiya.

Good idea based on wrong device. Sorry if I'm rude but the charger here showed is not able to supply 2.1A. It is a fake as many of them are: Look at the inductance if 1A pass trough it it will fuse :) also the IC is theorical limited to 1A ... look the datasheet or more easy put an amperometer.

I used a similar device: obviously it was not able to charge my device and i substitute the regulator with a real 5V 1A and the original inductance was melted in 5 minute. I changed also the inductance and all was fine but of the original device was survived only the case.

Please keep in high consideration the other user like bp_968 that suggest the usage of a proper device.

If you search ebay you can find a great little 4 port USB charger/adapter that works on 12v from the car wiring. It can supply a total of 4-5 amps I believe. I think it was all of 3-4$. I plan to build it into the car similar to this excellent design!

hehe kenapa tak terpirkirkan ya

My USB connection in the glove compartment, is only connected to my radio

maniacse (author)kkockelkoren2015-02-27

Pefectly stealthy!

kkockelkoren (author)maniacse2015-02-27

That's how I like it...
Was something I wanted to do for a long time

maniacse (author)kkockelkoren2015-02-27

Yeah, I made this in my previous car, but directly on dash board, and it doesnt look fine to me. In my current car I have headunit with USB on face, but headunit is deeper then surrounding panels, so I do not need this. Meybe in next car I made it again and like you did it.

kkockelkoren (author)maniacse2015-02-27

Thx man, for the compliment. I am happy with it....

I support John Grimoldy, the iPhone and iPad have highly intelligent charging circuits built into them. They will only draw the current required. The "iDevice" is able to work out through the centre pins of the USB device and determine what is kind of charger is at the end of the cable, this is done by measuring the resistance of the centre pins of the USB connection. If you present the wrong voltage to iphone or ipad it will not allow charging to take place. These devices have heaps of built in protection, specially surrounding the fact that this is a LION battery.

All modern devices work like that and have for years.

boodah (author)2015-02-27

Would love to see more about how you connected it to power.

Mocha0110 (author)2015-02-27

Jlichty fuse size depends on which kind of usb plug you'll use for your project. These usb plugs originally comes with suitable fuses so you may check internet for your usb plug. All of them gives suitable fuse size at their pages.

Mocha0110 (author)2015-02-27

Its a good project. I would add an on/off switch next to usb outputs just in case. Even if your car is not running, it will keep consuming energy from car's battery.

brosati (author)2015-02-25

i was looking to do something like this to my car but i would alway recommend adding a fuse when customizing electronic components in your car.

rehanch (author)brosati2015-02-25

fuse has been added with the wiring.

jlichty (author)rehanch2015-02-27

what size of fuse should be used?

maniacse (author)2015-02-27

Simple as that. Thanks for sharing!

eamonn50 (author)2015-02-27

Great idea if building/modifying RV's or camper vans. You can have a couple placed where you want.

yalcincimen (author)2015-02-27

very useful.

mmcl26554 (author)2015-02-26

I did the same thing 2 years ago but used a 3 amp 5 volt regulator, and USB ports (2) from a dead device. Used 2 regulators. Works great.

SoLongSidekick (author)2015-02-26

What type of console port was that? What was it intended to house?

dsantil71 (author)2015-02-25

That looks really nice. Just 2.1 amp ports are geared for larger devices like tablets & iPads. You can use it for your phone but it will generate more heat in your phone & may decrease the overall life of your phone's battery.

rehanch (author)dsantil712015-02-25

yes u r rite 1A port for phone n other one for tab.

SoLongSidekick (author)rehanch2015-02-26

That's not the case anymore, I'm not sure if it was ever the case actually. Modern devices will only pull as much amperage as they need. So you can plug a in phone that says it needs 1 amp that has an actual draw of .89 amps into a 2.1 amp port and it will only ever draw .89 amps. And these cheap 2.1 amp double ports are made with the intent of being able to plug two 1 amp devices in and have them charge at their normal rate.

john.grimoldy (author)dsantil712015-02-25

Having higher amperage won't generate more heat or reduce the life of the phone's battery. A phone will only draw as much amperage as needed for charging.

IsaacV1 (author)2015-02-26

That looks really clean. I might not have gone with the carbon fiber look myself, but you can get that in damn near any color/pattern you choose. USB charging sockets are seriously handy.

jockelleis (author)2015-02-26

Is there a parts list? I'm not real swift with electrical projects.

tnowling made it! (author)2015-02-26

did this in my wife's car because there was only 1 power port... I highly recommend it. mine was heat shrunk and fused as well..
