Nice one!


Saw these pics too...
I have made mine. I used batteries from an old DELL laptop and convert it to 12v 6000mAh and use car charger to stepdown the volt to 5v 250mAh 800ma -900ma

It can charge any type of phone under 1hr

Did i read "Any phone?"

Samsung Galaxy S4's standard charger is 5v 2A, 5v 250mAh would not even charge it if its on... the battery percent would decrease instead if otherwise.

Those things you put together can only charge Torchlight Nokia phones efficiently.

Dude, 250mah? That can't charge my phone.

A lot of smart phone if plugged to this will take forever to charge and even discharge if in use.

Guy...if a charger is not up to 1A, I don't consider it a charger. Even if it is 1, I don't like it cos I won't be able to use my phone while charging

Sure? Have you really try it? Then the OP's first pix will be the best solution to your phone

Why? I have 2 power banks. One is 30,000mmah and the other is 5,500mmah.

No need trying anyone except for experimental purposes

Okay. Good for you. For me, I like to manipulate with currents (volts).

There should be car chargers with that spec, or at least 700mAh or 1A.

Back then I used rechargeable lantern battery 6V 5A for 3.5-5V 1000mA batteries, once fully charged I do use it for full six hours while charging(when charging and using d phone at the same time). I get 2 days out of it when i use the normal way.
