    Intro: Easy rechargable portable ipod/USB rechargerUsing a USB socket, a four-cell AA battery holder, four rechargable AA batteries, and a four-AA battery charger, you can have a portable 5-volt power supply for charor powering your Ipod or other USB-powered device.

    Don't put non-rechargable batteries in the holder though, because you will wind up with 6 volts instead of five. The USB socket is supposed to supply five volts.

    One nice thing about this setup is that the batteries stick together as a set of four. They get drained together, and they get charged together. Also there are nocomplicated circuits.

    step 1:buy a battery holder, batteries, and a chargerYou will need a battery holder made for four AA batteries, with red and black wires coming from it. Radio shack sells these just like in the picture. Most likely, your locaHobby Store carries them too, and then you don't have to go corporate. Radio shark also sell a type which has an on/off switch, and a cover which is held shut by ascrew. I don't recommend that type. You don't need a switch and you don't want to be thwarted by a screw every time you need to charge the batteries.

    You can usually find a battery charger at a thrift store or in the free box at a college dorm building. Often times the charger is missing its power cord, and you can justmatch it up and be on your way. Buying a charger would be silly with all the free ones out there, ready to go in the trash because nobody wants them.

    Most chargers charge as two sets of two (one LED for two batteries) but some charge all four cells as individuals (one LED for each battery). Those are better. Everyodeserves to be treated as an individual.

    You can get rechargable batteries in a set of four. Cheap ones are 1500mAh, expensive new ones are almost 3000mAh. Get whatever is handy, and upgrade if you nto. Don't mix batteries that weren't born together, they will end up beating each other up. I am serious.

    step 2:Find a USB socket, or cableNow you need a USB socket, to provide a place for your Ipod cable or whatever cable to plug into.

    The first picture is a pair of USB sockets from a desktop computer. These are a good choice because they can be found free in any computer-junk pile, and the red anblack wires are already figured out for you. Don't cut off the other wires; you will need to put resistors on them later.

    The second picture is a socket-end of a USB extension cable. This is the easy too, because when you cut the cable you will see the red and black wires again.

    If you choose another type of USB socket, use the diagram to make sure you are getting the Plus and Minus correct. Red goes to Plus, Black goes to Minus. Make suyou don't have it wrong or you will destroy your fancy IPod. Then you can write an instructable about how to make an altoids tin out of your dead ipod (just remove deaipod guts and add hinges).

    Another option, if you have an extra IPod USB cable, is to cut the USB plug off of the cable and wire the red and black wires to the battery holder directly. If you do thiswith your only IPod cable, however, you will never be abe to change your music again!

    step 3:Wire battery holder to USB connectorBefore you start this step, put the batteries in the charger and plug it into the wall. Rechargable batteries are empty when you get them, usually, so don't skip this stepa few hours they will be full enough to test everything.

    Now you have to join the black and red wires from the battery compartment to the USB connector. Strip the wires, solder them, and tape them. Red to Red, Black toBlack.

    The result will be that when you put four RECHARGABLE AA batteries in the holder, you get 5 volts at the USB socket, in the correct polarity.

    step 4:Add resistors to the data linesLadyAda has discovered that many Ipods and other devices won't charge unless you put a couple of resistors to the other two USB wires. Fortunately you did not cut those other two wires (they are probably white and green).

    Get a pair of 100K ohm resistors (brown black yellow something, or brown black black orange something) and twist them together at one end. Connect that end to thewires. The other end of each of the resistors goes each of the remaining wires from the USB socket.

    You are basically connecting one 100K resistor between VBUS +5VDC and Data+,and another resistor between VBUS +5VDC and Data-.

    The second image is from the Mintyboost version 1.2, and is for reference purposes only. Ignore the right half of the screen. Ignore the fact that the resistors do notexactly connect to +5VDC in that schematic. If you want to make a mintyboost though, use that schematic.

    For more information about the Mintyboost, see the Mintyboost 1.2 FAQ:

    http://www.ladyada.net/make/mintyboost/faq.html

    step 5:Use it!All you have to do now is put it together. Put the CHARGED batteries into the battery holder, and confirm that the polarity is right on the socket - you can do this using USB laser mouse that lights up when i ts on, or a USB hub that has an LED on it. That way, if you have it backwards or otherwise wrong, you don't risk turning your ipointo a thiefbait paperweight.

    A hot-glue gun is the correct way to stick the USB socket to the battery holder once you're sure everything is done right. Make sure you don't get hotglue into the holesthe battery box where they will block the batteries from contacting their terminals.

    Now would be a good time to put an easy-to-read warning sticker on your battery holder that says, "DO NOT PUT NON-RECHARGABLE BATTERIES IN HERE ORDAMAGE MAY RESULT!"This is because non-rechargable batteries are 1.5 volts, which would total SIX volts - more than USB is supposed to supply. Probably the IPod would be okay with thisbut no guarantees that it won't turn your IPod into a shiny coffin for burnt circuitry.

    That's it! Hopefully the Ipod will continue to charge until the battery pack totals 4.0-4.4v and then stop. At that point it is time to charge the batteries the next time you gthe chance. Unplug the Ipod from this device when you're not using it, so that it doesn't keep trying to charge the Ipod after it's full.

    balkeeesays: Feb 20, 2010. 7:23 AM REPI just tested my rechargeable batts and im getting 1.45v I am guessing that would be too much for this setup? Im trying to make something similar to yoursetup just don want to burn anything up.

    NoahMsays: Jan 18, 2010. 4:38 AM REPNo offense, but you are wrong about the battery case with the ON/OFF switch. I have one, and the screw is not necessary. It is only a cover that is a l ittle

    hard to put on. It's not THAT hard, though.

    whocares88says: Oct 3, 2009. 7:38 AM REPhow many full charges will you get for the four batterys?

    pancho del ranchosays: Sep 22, 2009. 6:59 PM REPwat f u get a 3 AA batttery holder it would be 4.5v will that work

    jerkeysays: Sep 23, 2009. 3:11 PM REPWhile fresh non-rechargable AA batteries are 1.5 volts, they sink to about 1.3 volts when they're depleted. I haven't tried, but I don't think the Ipod willcharge at such a low voltage. Besides, have you ever seen a three-pack of AA batteries? We have to stop buying so many disposable things anyway. didn't mention this in the article, but it would be possible to safely use regular batteries in this instructable IF one placed a regular diode like a 1N400? iseries with the battery pack. This diode would subtract about 0.7 volts from the total, bringing the voltage of fresh non-rechargable AA's down to a safevoltage like 5.5v. I mentioned in the article that Ipods MIGHT be okay with the full 6V but i'm not going to try it myself.

    pancho del ranchosays: Sep 23, 2009. 6:13 PM REPtrue i have a 4.5 volt regulator if i put the 1.5 batterys. also to charge a i pod dont u need to put a resistor on the left over data cables or the i podwont charge i read it on another instructable. also i thought for any damage to inflict the i pod it had to be 4.8 to 5.2 just read that to so is that thecorrect voltage needed

    jerkeysays: Sep 24, 2009. 5:05 PM REPThanks for mentioning the extra resistors. I will add that to my instructable.

    barney_1says: Sep 23, 2009. 7:32 AM REPIf you value your electronics, you need to use a voltage regulator. Please make sure to update this when you kill your device.

    jerkeysays: Sep 23, 2009. 3:08 PM REPactually, the great thing about this method is that you DON'T need a voltage regulator. The basic chemistry of rechargable batteries hasn't changed inmany years, and they are still 1.2 to 1.25 volts nominally, which totals 5.0 volts. The USB standard is between 4.5 and 5.5 volts, and that range fitsperfectly with the full-to-empty range of a set of four rechargable batteries. Thanks for cautioning readers to be careful, but I already did that.
