Introduction: 3g Iphone Mobile Charging System!!
So the 3g iPhone's battery sucks if you use location services and 3g all day.
So, I build a dock into my bag and wired it through to an inner pocket where theres a portable battery. Now, whenever i slip my iPhone into that pocket, it gets charged!!
Step 1: Buy All the Crap You Need!
get yourself a 3-pack of iPhone 3g universal dock adapters at a mac store. it'll run you 9 bucks.
then, the awesome part is the tekkeon (i have no commercial relationship to them, just a happy customer!) rechargeable mobile power unit, purchased for $36.95 on newegg.. basically, its battery pack with a 4,000 mAh capacity (iPhone's battery is 800 mAh i believe) that outputs power to a usb port! perfect for the iphone!
obviously, you need the sync cable, and the iphone itself.
oh, you'll also need some krazy glue, or other adhesive that works on plastic.. might wanna get a sharp knife too..
Step 2: Hack the Crap Out of the Universal Adapter So As to Fit the Sync Cable Through..
unfortunately, i am not good at all with plastics, so you'll have to make do as best as possible, but i
1) took a knife and shaved the sides of the sync cable, then
2) melted a bit of the hole in the universal adapter so as to fit the sync cable through.
3) krazy glue both parts together like crazy until theyre solidly affixed!
it looks like crap, but considering that part remains hidden we're going for function over form here..
when it fits through, and try to get it as flush as possible---
if the cable isnt through far enough the phone wont connect well enough to charge, and if its too far through it'll be hard to get the phone to lock in easily..
Step 3: Insert the Whole Thing Into Your Backpack, Knapsack, Rucksack, Man-purse, Kangaroo Pouch, Bellybutton, Etc
I used a man-purse, personally, and i think this project is best suited to one, but whatever..
i cut a small hole on the inner side of the pouch on the man-purse so as to run the cable through to the inner pocket where the battery pack resides..
the dock then goes in the side-pouch, and the wire obviously gets run through to the battery.
i shoulda made this clearer before, but that battery has enough juice to keep my iphone alive for about 3 days seeing heavy use... thats pretty damn good eh?
heres the schematic:
Step 4: Win!
congratulations, you win at life!
the bag is a Tumi, by the way, before anyone asks.. www.tumi.com
