Introduction: TransparentSlim USB Powerbanck

Simply and easy to make

Step 1: Materials

Electronic part from a old powerbanck,plexy,soldering materials,hot glue,transparent scotch,new slim battery

Step 2: Assembly

Open the old Pb and take only the electronic circuit,change battery(same type on volts) 2200 mA or above

fix all parts on the plexiglas with hot glue and cover with transparent scotch.

use the old cable to charge battery from a USB.this project is for many and différents usage like bluetooth boombox,smartphones,camping lamp(with mini usb led light in my other instructables)....

thank you to watch....

WARNING!!!!
That is a lithium ion battery right? BE VERY CAREFUL!!! If that punctures it burns over 1,000 degrees Fahrenheit or over 500 degrees Celsius (not exact conversions but they still get the point across and are true). That means even bending it too much can start the chemical reaction that makes it burn! I do not recommend leaving the battery unprotected like that.

I am on the app so I can not edit my comment but also be very careful about over charging it and over draining it. Both can damage the battery. I currently can not remember off the top of my head exactly happens when you do either. Can someone else please remind me and enlighten the rest?

The circuit board from the powerbank SHOULD prevent over/under charge condition.

As long as the li-po cell is of equal or greater capacity than the li-ion cylinder cell it is replacing, the only noticeable difference should be form factor, and a SLIGHT increase in time to "full" when charging(because the li-po likely has a slightly higher capacity)

The plexiglass should limit bending enough to prevent that danger, but it is still at risk for puncture. That being said, so are all the batteries from my old phones. Reasonable caution when handling and storing should mitigate any major risk.

the two batteries(old and new)are lithium-ion.the dimensions are différents.

the electronic circuit inside is for this type of battery(charge and discharge).

this powerbanck work every days without problems(build ending Agust 2015).

Scotch and plexyglass (i think....) protect sufficiently the battery(no kid here)...

thank you for the comment.... :)
