How to build an emergency charger with two AA batteries

[sunny127]

If you are tired of your battery draining off too rapidly ( Especially when using over clocking software like Pocket hack master and XCpuScalar) then you might consider building your own emergency charge device, like described in the fallowing link:

Let's remember how odd this will look if you're trying to go on an airplane with a small Altoids tin with batteries in it!

It´s really nice, but for this price for one pice (20$) and the time to build it, it´s cheaper and easier to buy it ready made.
I get it for 10€ incl. shipping and then with four batteries.
