Introduction: Micro Pocket Power 2 Go Its Solar To

Picture of Micro Pocket Power 2 Go Its Solar To

Hi there ,
I wanted to share a project I made a few months ago ,
I call it power 2 go , yea I'm still working on the name ,
its very small as you can see in the pictures compared to a memory card and the penny ,  
I know there's a lot of people out that have made similar to this and I must they did really well ,
but I made mine a little different a more adaptable version meaning that it can be charged not just by solar alone ,
but by usb as well , that"s not anything new you say , 
ok how about this you can charge your cellphone with it ,
no still not something new ok ok I here you no problem ,
well how about this ,
 something that makes it little a different then others it can be used to power anything that has a usb port or charge port  , 
and it can be charged by a bigger solar cell to speed up the charging process , 
what your still not impressed yet  hmm ,
wait please don't leave yet  were just getting to the good part ,
check out  how to build own power 2 go in these couple of easy steps .

UPDATE ! Thanks to the feedback of a fellow member I updated the last step , IT will have the specs and how it works 

Step 1: Get Your Tool Box Handy

OK so here's a list of things you need ,
A  mini case to put all the parts in , I used a GameCube memory card case it fits everything just right  ,
A solar cell , almost any  kind will work  like one from a cheap solar light will do , p.s make sure its small enough to fit the case ,
A bridge rectifier diode , got mine from ebay , 100 for a $1.50 mind you only need one ,
A 4.5 volt micro rechargeable battery , you can get this on Ebay if you want or maybe a hobby store , 
A female USB Port also ebay or if your like me you have a few laying around , 

now for the tools ,
glue gun 
soldering gun 
and a hobby knife ,
note be careful when using cheap hobby knifes , 
ok on to the next step

Step 2: Let the Fun Begin

Picture of Let the Fun Begin

ok since I did not take any pictures when I was making it , 
I can't  show step by step with pictures sorry :( , 
but don't worry I have your back , 
I have made a schematic so to speak  by using windows paint to make it ,
ok I now its not how  some of you pro's would do it but I wanted it to be very simple so anyone could this , 
also I though I would post the pinout website just in case you what to use a different type of usb , 
so you can find the pinout here , 
ok fallow the schematic like it shows you and solder your components ,
then place in your case making sure you have cut two holes one for your usb and one for the top of your solar cell ,
now glue everything in its place ,
once done ,
you  need to use the glue gun and glue around the top edge of your solar cell to seal it up ,
or take some clear plastic a melt it around the edge with your soldering gun , that's what I did
 please be very very careful when  melting the plastic it can burn you very easily , do not let your children do this
ok next and last step


Picture of THE BIG TEST

ok take out side and put in the sun of course and let it charge up ,
depending on the battery and how sunny it is it could take awhile ,
mine sometimes takes all day when its without a charge ,
so if your like me and can't wait  for a couple of hours because your to exited  then plug it into a bigger solar panel like I did ,
or plug it in to your usb charger or the usb port on your computer ,
yes its ready its ready oh sorry I lost control of my self for a second can't be help :) ,
so there have it your now have power 2 go  , 

have fun and thank you for viewing , 

UPDATE , ok I posted the specs and how it works , 
ok lets start with how does it work , 
well think of it as a regular rechargeable battery ,
when you plug it into any power source like a charger it well charges , 
and when something is connected to it , it  will power what you've connected like say your cellphone , 
there is no chip or component to tell when and when not to charge ,
I know what your thinking if there's nothing stopping it from steal power from what is connected right ,
don't worry I'v though this out ,
when you charge a battery there's a higher voltage and lower voltage ,
what doe's that mean ,
well when you look on the label on your cellphone charger you will see its a volt to two volts higher then your battery ,
for example charger is 5.1 volts and your battery use's 3.7 volts ,
ah you see so what's it taking place here ,
when you connect a higher voltage to a lower voltage the lower voltage will take on the charge ,
of course you say   , hold on were getting to the good part ,
anytime you connected higher to lower the higher wins each time , wait what about the power being drained by the charger ,
ok I see what you mean ,
when the voltage is higher like I said the power will flow into the lower and will not back flow out ,
I'v tested it to be make extra sure ,
so that's why you always need a higher voltage when your using it to charge something , 
thew ok , now to the specs ,

specs for charging time are ,
4 to 8 hours by solar , depending on the amount of sun , so if its cloudy you'll be looking at about 8 hours , 
by DC charger 2 to 5 hours max , 
by it own solar and help from a bigger panel is 1 to 3 hours ,

I hope this helps everyone know how it works and what the specs are ,
some  of you may know most of this but hey we were once newbies to , p.s you may learn something new  ,

as  always Thank you for viewing and say tuned for more  projects from your truly

HI everyone I just update the last step with how it works and the specs ,

smoth_paradox (author)2013-07-13

For a noob, how does it work for the usb port to charge the battery if it receives power from the exterior, and to charge a cellphone?
I mean, how does it know when to receive and when to send energy?

And also, with those specs, how long does it take to fully charge a cell phone, if the battery is full?
