How to Make Easy Powerbank / Charger Portable Rechargeable AA Batteries Using 4 pieces

Now again the rise of smart phones with very cool features , let's call it a smartphone with a reliable operating system displayed very comfortable in the eyes . With operating systems are so powerful , it is not uncommon smartphones more electrical energy from the battery drain . So we had to commute HP charger , it is very inconvenient if you have to carry a charger electricity , especially when away from the reach of the power source .
To get around it made ​​POWERBANK , well here I there a way to make POWERBANK very easily without any additional electronic circuit components , a simple one .
Let's look at the steps in making it .
1 . Prepare 4 pieces of rechargeable batteries or rechargeable with amperage up to you . But here I use the 700mAh . Customize your phone with a innate charger . Usually written output : 5 volts :: 550mA .
For class smartphone battery usually more than 1000mAh/1Ah .
2 . Prepare 4 pieces of the battery compartment . If you do not have to buy the electronic stores .
3 . Prepare cable , usb female , solder , tenol , multitester , and others .
4 . 4 Make sure the battery is fully charged . Then put the battery in the right direction .
5 . Connect the cable from the battery to usb female , or can be directly soldered to the battery compartment . Be sure not a wrong number . See the image below:

Note the positive current (+) and negative current (-) of the battery connected to the usb not to reverse, check first with each cable multitester really sure, do not dwell pd cable colors.

Usually the USB 2.0 cable wires are 4 colors, namely black, white, green and red. But sometimes there is no green replaced blue. Well, if you are confused to focus on the colors red and black wires alone. Because the color of the other for data transfer, red and black for power / power. Usually the red color symbolizes the flow of positive and negative current Black / Ground.

So if you are confused directly connect the positive pole of the battery to the USB cable and the negative pole of the Red color to black.

Pole Positive (+) and negative (-) battery usually in as shown below:

6. Tests with multitester if the current is correct. If you are sure, can directly plug into your phone. If successful the phone will be charged.

The explanation:

-Batteries with greater power will flow to the smaller electric power.

-1 Rechargeable batteries with a capacity of 1.2 ampere-volt variety. If 4 pieces of batteries in series means there are 4.8 volts and amperes fixed. Do not use regular batteries due to voltage of 1.5 volts and amperes small.

-If the mobile phone battery is not charged, you can try adding 1 rechargeable batteries again. So in total there are 5 pieces.

The top and bottom of the picture is the result that I have created and successfully charge the Sony Ericsson K510i mobile phone battery to full.

If you've managed to charge the battery into the phone, cables can you can trim them with soldered directly to the battery terminals, or your insulation is neat.

-Be careful in the making!
