Picture of Make a USB iPhone iPod Charger On The Cheap!

There are many designs for iPhone chargers out there and many are confusing or use parts that are hard to find.  My design uses parts that are easy to find, is tested works with all iPhones and iPods (as of this posting), and just works.  It is a fun and useful project.  I made one a few years ago and put a video on YouTube.  I weekly get many questions about making one.  So here you go and i hope you enjoy it.

Step 1: Parts List:

Picture of Parts List:
  • 1 - SPST Switch (I used a toggle switch)
  • 1 - LED for "ON" indicator red or green (Radio Shack sells LED's with resistor "350 ohm" you can mount.  That's what I used.)
  • 1 - 350 ohm Resistor
  • 1 - 7805 Voltage Regulator
  • 1 - 22uF Capacitor
  • 1 - 10nF Capacitor (code 103)
  • 2 - 33K Resistors
  • 2 - 22K Resistors (Other values can be used, read step 2)
  • 1 - Female USB Connector (I got mine at a dollar store)
  • 1 - 9v Connector
  • 1 - 9v Battery
  • Electrical Tape
  • Solder
  • Soldering Iron
  • Small piece of perfboard
  • Altoids Tin
  • Dremel Tool with cutting attachment or tin snips to cut the tin
  • Drill for switch and LED hole
  • Hot Glue
  • Paint if you want

You can go here for a good tutorial on soldering. 
For most of the parts you can use techno scrap and recycle old broken electronics or just buy them.
I wanted to use parts that are easy to find and inexpensive so everything can be bought at Radio Shack or if your don't mind on-line shopping I like because it's cheep!  
I hope you enjoy the project.  

Warning: Just a fair warning that there is a small chance that something can go wrong and you can end up frying your really expensive iPod.  Be careful.

ref: "on ether side of the regulator a capacitor is placed to smooth out the current a bit." Why?

Your power source is a battery. Unlike a rectified AC source, there shouldn't be any ripple. Or am I missing something?

The painted tin is quite nice! ;-)

Hello I am doing somthinlike your project but what I was planning is make the charger being able to connect to a connector in the wall but I am not really sure how to... do you think you can help?

I've only tested it on an old Samsung Galaxy. Works great so far!

My first real circuit. I made a lot of mistakes but they were worth it for the knowledge gained. I liked this instructable because it's totally functional, it looks cool so you can show it off to your friends, and it was just challenging enough for a beginner. Thanks man!

This is a great instructable but the use of a 9v battery means that you get very little juice out of it. I'm rather a novice at this stuff, what would I need to change to replace the 9v battery with, lets say, 4 AA batteries?

Thanks again for the fun project.

You can find a pretty cheap step down modules at ebay. Like this one:

Well, I have been extensively researching to find a 6v to 5v voltage regulator... And apparently, to my surprise, there are none. So, you can do what I'm doing and use 4 AAs and 1 AAA in an altoids tin with a LM1117 voltage regulator. But if you're trying to charge an apple device you'll need to put a variable potentiometer between USB pin 2, and 3, then adjust it until the ipod accepts the charge.

this is nice. How much did it costs you to do all these? Thanks man!

how many watts did you used in the 350 ohm resistor???

Made a circuit like this, just modified to feed Samsung phones (works on notes, only Samsungs I have around). They need to "see" 1.2V in the data lines of a USB. Check out my charger, its an instructable.

Hi again. I'm also wondering if both voltage dividers are necessary for current reasons or can you just use one?

Hi, took me some time but I finally managed to make it. USB inputs are opposite of what I expected. For some reason it didn't occur to me that that was my problem so I spent forever adding and removing components. As a result my circuit is unbearably messy. I just started learning Eagle PCB and I want to get a board printed for this. Would you have any problem with me getting a manufacturer to print a board for this design? thanks

wait so you are a kid in middle school and you made this?

Yep. Easy if you just put you're mind to it and know how to do it. Made a few other things, just check them out. Go to my page.

Can we use this circuit to charge PlayStation Vita charger?

I have made it... but my iPod wont let me put photos onto my computer :-(

How much is CHEAP? what's the total cost of this product?

It depends on if you have the necessary tools yet, or not. You can pick up a hot glue gun for $5 at Home Depot. A really nice Dremel tool will run you around $50-$60. All of the components are pretty cheap, costing me about $10 for them all.

im trying to find all the parts for this project. I cant seem to find the 10nF resistor anywhere. Any help appreciated...

I know its been a year, but for anyone else with the same question, 10nF is equal to .01uF. The capacitors I have found are labeled as .01uF.

how would this design be modified for android devices? Am I'm mistaken in thinking that the two volts on the data line would be unnecessary? If so, would you even need the pcb and all those resistors and capacitors? Wouldn't a voltage regulator be enough?

matt826108 months ago

can I use a LM317 and place correct parts to have an output of 5v and substitute it in?

it works with moto g or samsung's cellphones?

Rodville9 months ago

Would this work with 12V instead of the 9V?

hey rodville yes it will work with 12v but be aware of the amps that the battery gives out. Since this battery only gives 500mAh

My battery pack puts out 3a max

Ok after some research i found out that the input current doesn't matter which means you can use the battery but you will need a heatsink becuase it would dissipate a lot of heat.

I am trying to build this charger and the instructions call for a 350 ohm resistor but the closest I can find is 330 will it still work, or will it destroy my brothers phone
ryoung26 jhosborn9 months ago

It will work; that resister limits the current to the LED.

dustinfathead11 months ago
So some of these parts listed don't have their volt listed. The 22ufcap has dif volts. Any help? Just want a more accurate parts list.

ANY voltage for that cap should work.

My 16 year old son decided to make a charger for his iPhone. He had NO electronics knowledge prior to this project. He taught himself to solder from a different Instructable, and we chose THIS Instructable as it was clear about the need for the 2 volt data signals to get Apple goodies to accept a charge; it had a good materials list; and an apparently clear schematic.

Unfortunately, we found the schematic and the instructions a little hard to follow.

1. Pin 1 of the USB receptacle is not labeled on the schematic. Thus, my son soldered it all together backwards - we didn't discover this till I found a USB pinout FYI, the TOP pin in the schematic is pin 1, which is the LEFT pin looking at a female USB with the "board" at the top, and is the +5v input.

2. The materials list did not specify what type of perfboard to use. We used bare, but in the pictures you clearly used perfboard with plated holes. Shame on us I suppose for not looking at the pictures BEFORE going to Radio Shack, but we sure scratched out heads at the step:"Solder the red (positive) wire from the battery connector to one pin of the switch and from the other pin to the perfboard."

3. About those pictures - they are too blurry to be of much use, frankly.

Overall, this is a GOOD Instructable, but I'm a little disappointed it was Featured; a little refinement and it would be a GREAT Instructable.

ryoung26 ryoung269 months ago

One more thing - the heat sink you clearly used to mount the voltage regulator is NOT listed in the material list. These voltage regulators are pretty sturdy; the current is not very high; and it doesn't last very long when it flows, so I think the component will live until my son loses the charger <grinning>,'s another point where this Instructable is Worthy Of Improvement.

Can u plz explain how to put this together in depth plz

Hey I was really confused reading this????
lharp76811 months ago

did it without the 10nf cap. no issues. love this! thanks for the schematic.

also I used an old Wizard brand 1/2" socket for a heat sink.

Will this also work for the iPad? What about linking more 9V in parallel to get more amps? Like, same setup, but with 3-4 9V's in parallel?

dbaham made it!1 year ago

First project in a long time, I probably should have spent more time on the board layout, but it all fit.
