iPhone Chargers

I have seen many 'ibles on battery-powered USB chargers that say they cannot charge iPhones/iTouches because they require power to be supplied to the data pins. How, then, have I seen iPhone chargers (that work) with only two inner wires - a red and a black?  I recently bought an iPhone charger, so I could cut the wallwart off and use it instead of a USB port in this circuit. However, I have discovered that it only has 2 inner wires, as previously detailed. How could I use a 9V (PP3) battery and a 5V (7805) voltage regulator to turn this into a battery-powered charger? Both of the above questions are ones I would like answers to. Thanks in advance, ~H4ZZ

Iphone charger, 1A.

Hello I have a Iphone 3Gs with the original Iphone charger. On the charger it says that it supply's  5V,1 A, and a normal computer usb-port supply's 5V,0.5 A. Is it safe to use my mp3player with the Iphone charger? On my mp3 players charger it sayd 0.5 A but I lost it. Can my mp3 player's battery break if I use double the current that is recommended? Question 2: If I buy those Iphone chargers on ebay, is it safe to use them on my Iphone? cgi.ebay.com/ws/eBayISAPI.dll Question 2: If I leave my charger in the outlet will it still draw current? Without any devices attached to it?

iphone solar charger (again)

Have read through alot of topics but cant find my question answered... If i use 5v solar panels, with lets say 1000mA  power, and simply solder wires from panels to a female usb connector ex. if i buy a usb extension (male one end /female other end) and cut away the male part and solder the other female part to panels would this simple circuit charge a iphone ,,or would there have to be other electronic parts involved to make charging happen? If this does not work , im thinking of buying a car usb socket and solder to 12-15v panels ,   that should be bombproof as long as you now that the specific socket works with iphone right ? Downside of that , as i read somewhere on the net is that you loose power when transforming current down from 12 to 5v ? is that right ok hope someone has got a answer to me  regards

Altoids Tin Can Charger

Hi, ive made an Altoids tin can charger awhile back and it chargers all my devices but my iphone 5s? Its charges my iphone 5, 4, 4s, and every ipod. What circuitry do i need to allow my charger to charge my iphone 5s? Right now i have a 5v regulator and 2x 200ohm resistors off the positive lead into the positive, data -, and data + connections. Should i add capacitors on the inputs and outputs of the 5v regulator?  The only reason i build my own chargers is because i take long trains rides and flights and i use my rc car 5000mah battery that can last me a week, i put all the circuitry in an Altoids can to hold it together.

Solar USB, iPhone, Arduino Chargers

I write up a lot of guides on Instructables for various solar gadgets.  Most of the Solar USB/ iPhone/ Arduino chargers.  If anyone is interested in such things I sell them off my website, which I then use to make more projects or fund activities in my science classroom.  I have several versions of my kits available as well as all the parts to make those kits, and even premade chargers for those who don't feel the urge to make one on their own. Solar USB Charger and Kit A basic USB charger that uses rechargeable 2 AA batteries, a DC to DC boosting circuit, and a 4V solar cell.  Take the batteries out to charge, or leave it in the sun for a few days.  Then charge up your gadget when need be.  Works with most USB devices including Apple products (iPods, iPhones, iPads) as well as Arduinos.  Fits nicely into an Altoids tin. Solar iPhone Charger and Kit More or less the same as the USB charger, but instead of having a generic USB port it has a dedicated iPhone/ iPod/ iPad cable.  Which means it only works with Apple stuff.  Features 2 rechargeable AA batteries, boosting circuit, Apple Connecting Cable, and 4V solar cell.   Heavy Duty Solar USB Charger and Kit While the 4V solar cell in the other kits/ chargers fits nicely inside an Altoids in it is also quite wimpy.  I took the basic design of the Solar USB Charger and replaced the 4V solar cell with either a powerful 6V 230mA or a 5.5v 320mA solar cell.  In order to make things easier the solar cells plug into a 2.5mm jack on the side of the tin.  Meaning you can leave the solar cell at home.  The solar cells are also powerful enough to charge up a lot of gadgets directly from the sun if you have good weather.  Works with most USB gadgets, Arduinos, and Apple products. Lithium Heavy Duty Solar USB Charger and Kit Due to the fact that big gadgets (like iPads) have insanely big internal batteries I had to modify my design a bit.  The AAs in the other chargers were not powerful enough (unless you used 4 or 6 of them) to reliably charge up bigger items.  I modified the design of the Heavy Duty Kit to replace the AAs with a Lithium battery and Charge Controller.  With several battery options available, including a massive 6,600mAh one, these chargers have no problem handling the larger power needs.  On a recent plane flight a charger with a 2,000mAh Lithium battery charged up my iPhone over 80% (on airplane mode while listening to music).  Imagine what a 4400mAh or 6600mAh battery could do.  The charger/ kit can fit inside an Altoids in with the smaller batteries.  It features a powerful 5.5V 320mA solar cell and a 2.5mm jack and plug system so you can easily remove the panel.  A nice addition is the Lithium Charge Controller which has status LEDs showing when the battery is charging and when it's full.  It works with most USB gadgets, including Arduinos and Apple gear. I've used these kits with kids at my middle school, and have sold many kits to summer camps and scout groups.  They take between 20 and 45 minutes to make, and only require basic soldering skills to put together.  They all fit inside Altoids tin for cuteness factor, but can easily be put into something else.  Modifications are endless. So there you have it.  More Altoids solar thingys than you can shake a stick at.

Solar powered cell phone charger case hack

After finding solar chargers and DYI solar videos I had an idea... I'm getting an HTC Evo soon. This phone has a lot of screen real estate. It's going to require a decent sized hip case. Why can't I slap a couple solar panels on the outside of the case with a small USB cable plugged into the phone while it's resting on my belt? I want to take advantage of the size of this thing and have my own hacked solar case. So here's my idea. I want to grab a couple panels out of some all-weather garden lights. Mount two solar panels to the outside of a good case when I find the right one. Then add a 5V regulator wired to a mini-USB plug. When I put my phone in it's pouch I could just plug the end of the short wire into the phone to charge it, or at least help it keep a charge while I'm out and about without having to worry about carrying around a solar kit to pull out and pay attention to. The reason I need advice. I don't know much of anything about solar panels other than what I've heard in other DYI tutorials. I'm not an electrician so I don't know much about the power requirements of the phone outside of standard USB voltage. What would I need for amperage requirements? Is a 5V regulator enough to ensure no damage to the phone? The phone will only pull as much amperage as it needs as far as I understand it. Will the phone safely stop charging when it's full or will I blow up my battery? I know they make cases for iPhones like this for $80+. I think I can build one for ~$20 save for the actual case itself. Any help would be appreciated. Thanks *EDIT: A little bit of clarification on my project. I've looked at a lot of other Instructable projects as well as ones all over Google. I've got a lot of good info from them, and I know I *can* do this, but because I'm trying to charge such an expensive device I want to make sure I have every little detail worked out. I've read warnings about issues with part of a solar cell being in the shade (wasn't detailed on why). With my scope of electrical understanding, I would feel comfortable following these guides if I was doing the exact same project with the same amount of panels, but I'm going to have to change things up a little bit mainly due to space and weight constraints since this is going to be mounted on my hip. The biggest requirement here is that the panels produce enough power to charge a USB device without having to trickle charge a separate battery first. I won't have the space on my cell phone pouch for an extra mounted battery. The entirety of this device should be no more than the pouch itself, one or two solar panels and a few wires. The main concern here is getting the amperage I need to charge the phone faster than it drains with only one or two panels.  I'm not looking for step by step instruction here, just a bit of advice from someone who knows a thing or two about PV to give me some tips on solar panel size and power. Also any safety precautions I need to take to keep from causing electrical damage to my phone.

Raspberry PI power?

Hey yall! I just recently bought a Raspberry Pi! Those of you who want to order know how hard this is, so Im pretty excited because i didnt think Id b able to order for awhile. Anywho, I wnat to make or buy a portable power supply for it, but I am not sure how to go about doing that. I know there are tons of portable CHARGERS out there for iphones and what not, but I am afriad these will attempt to "charge" my PI, therfore frying the board. Do they just supply power and the device recognizes power being recieved, so it displays charging? And I will be attachin a BUNCH of things via a usb hub to the Pi, so I doubt regular bunch of 4 rechargeable AAs will pwer my device for long with all thse extrra things drawing power. So my question is 3fold: can I buy one of those portable chargers to power my Pi or will it fry it? will 4 AAs be enough to power the Pi and all the extra usb things? and will it be more cost efficient to make a power supply? (I definetely want it be rechargeable, though). Any links to products, or guides to make one would be extremely helpful. Thanks in advance!!! Also, I already have a wall supply, but I need a power supply that is portable.

Laptop battery to charge cell phone or tablet

I have a couple of L11S6Y01 Lenovo Lithium Ion batteries 10.8V nominal, 48WH, 4400mAH batteries and a couple of their AC adapters lying around the house. I was looking up the Minty boost DIY battery back up and I was thinking of making this battery back up kit to recharge my iPhone and Samsung tablets, both of which can connect to USB power sources. My idea: 1) Get a 7 pin connector that will connect directly to my AC adapter. For example: http://www.ebay.com/itm/External-Laptop-Battery-Charger-for-Lenovo-IdeaPad-B570-G470-G570-Z570-L09L6Y02-/121091427052?pt=Laptop_Batteries&hash;=item1c319c8aec Maybe I can scavenge one such connector from this place:  http://www.ebay.com/itm/IBM-X60S-Battery-Connector-/350772373819?pt=UK_Computing_Other_Computing_Networking&hash;=item51aba9a93b 2) Build a circuit similar to Minty boost : http://www.ladyada.net/make/mintyboost/icharge.html Except in this case, my source is a Li Ion rechargeable battery instead of 2 AA batteries. Any ideas and thoughts would be appreciated.
