Please vote for this if you like the project!!

Step 1: Preparation

Materials:

  • Altoids container or small container
  • cell phone car charger
  • gator clips/cables (2)
  • 9V battery
  • 9V battery snap connector
  • electrical tape

Tools:

  • scissors
  • metal cutters/metal snips

Step 2: Wiring

Take your gator clips and connect one end of the gator clip to the positive wire of the snap connector. Connect the other end of the gator clip to the metal contact on the end of the car charger.

Take one end of the second gator clip and connect it to the negative wire of the snap connector. Connect the other end to one of the metal contacts on the side of the car charger.

Then wrap all the connections in electrical tape so the metal container doesn't interfere with the circuit.

Step 3: Cutting

Connect the 9V battery to the snap connector and put the wiring in the Altoids tin. On the outside of the Altoids tin, mark where the USB plugin is located. Then use metal cutters/metal snips to cut out the section you marked.

Step 4: Finishing the Project

Insert the wiring, 9V battery, and car charger into the Altoids container. To use, insert your phone's USB charger cable into the USB port though the hole in the Altoids container. Then plug it into your phone. Now you have a homemade portable phone charger that you can keep in your pocket or glovebox!

How many times the 9 v battery can be used to charge the 2900 mAh battery
<p>ZERO times..</p>
<p>true</p>
I made mobile charger but it is not charging my mobile it draining my mobile. Pls give me ans why is it heppining. Thank u
Did you hook up wires correctly or backward?
I plan on using this idea for my science fair project. Are you positive this isn't a scam and it really actually works?
<p>it is not fully explainable</p><p>please add some more points</p>
<p>ok</p>
<p>This would never charge i tried and i wont here is why</p><p>9volt batterys generaly produce around 450ma (millamps)</p><p>Phones And ipods Need 1 amp of power 4 -5 AA batterys will work ipads on the other hand require 2A BTW if you are thinking should i buy a portable charger off of ebay or do this do this its way cheaper</p>
<p>you should buy it of ebay or whantonn.com</p>
I'm sorry it didn't work for u. I think u made it wrong because it worked for me and there is even a commercial product called wonder cube that uses a 9v battery to charge an iPhone.It might work if u used two because I use two on an updated version I made for myself and it charge more of the phone battery and it did it faster
<p>Most smart phone batteries are 1500-3300mah.</p><p> A 9V battery has 50-400mah and at 500mw load has less than 300mah capacity.</p><p>You're also losing 30% of that 300mah thru the circuit.</p><p>Just exactly HOW much does this remaining 210mah charge your phone ???</p><p>Ref : <a href="http://www.powerstream.com/9V-Alkaline-tests.htm" rel="nofollow"> http://www.powerstream.com/9V-Alkaline-tests.htm</a></p>
<p>tnx for the intractable its great but u dont need the snap connector you can just attach the alligator clips to the battery and its done</p>

Y not dismantle the car adaptor to save space... and how effective is a 9v charging a cell phone? my phone batter is 12.5wh (Samsung Note3) I'm not sure I would get but a sustainable 5 minutes.
<p>thanks for the suggestion! I got 1% in five minutes with an almost dead 9V battery and an iPhone 4 i guess you could amp up the power of the battery if you wanted to.</p>
<p>You make a good point with daisy chain, that might help, bigger tin also...</p>
<p>This is so cool! I love that it's in an altoids tin. Thanks for sharing!</p>
