power supply to usb
 
Heading may sound odd but here goes.:D

I want to be able to charge my iphone from my 12v power supply that i use for my chargers. Does anyone know how? as dont want my phone to go flat when out.

Just modify an iphone car charger to add 12v input connectors, crop clips, banana plus or whatever you use, to 12v leisure, or PSU, etc. you could also get a 12v car socket, with croc clips/banana plugs on and just plug in your regular car iphone charger. There are lots of ways.

As above - try this at Maplins:

Or...
use an 4 way extension lead and plug it in 240v right next to the same plug you use for the power supply

politely guys where does it mention 240v in original post ?

i do of course stand to be corrected and eat humble pie

Cheers guys:thumbsup:

Just to add add to above I bought this ......

I cut the wires and the rejoined them using banana plugs (male and female), this way I can still use it in my car/van, it can be plugged into my power supply or dis board and I also have some crocodile clips with female banana plugs so I can hook it straight to a 12v

Can anyone using this confirm that their iPhone likes it? I tried this once and the iPhone said that the charging management system would not support this charging system. I assumed that the CC/CV charging logic is in the charger, and not in the 'phone. If that's the case, then using this system could fry the battery in the 'phone.

Like Fidspeed, I stand to be corrected and have the humble pie waiting in the microwave! :)

do apple not sell car chargers that would plug into the cig lighter?



if your correct typical apple... my htc charges of a usb lead ok

I can confirm my phone is fine after using the device I pictured in post #8, it even mentions iPhones in the advert I posted. I'm not sure of the in's and outs of voltages and amps but is it not a similar idea of plugging it in the side of your laptop via the USB link you get with your phone? It charges then.

@MC yeah I'm sure apple and others do do chargers that plug in a cig lighter but you would still have to connect the cig type plug to your 12v some how?

I bought a Cigarette to USB device for about £2 from ebay. Take it all out of the case, and solder 2 leads on the end and job is most definitely a good one. Plug the std apple (or alternative ebay fake!!) into the usb and it charges my iPhone.

I had this problem after getting an iphone stand from ebay. Found it was the lead that came with it. So i would try another lead as i did then all was fine. :thumbsup:
So they must make usb leads that dont do charging:(
