Make Your Own 9V Battery-Powered USB Charger





9V battery ကိုသံုးျပီး USB charger ေလးကိုယ္ပိုင္ျပဳလုပ္နည္းပါ.....
လိုအပ္တာေတြကေတာ့...





{ 1 } 9V battery
{2 } female USB port
{3 }+5 V IC
{ 4 } 9v battery cap တို့ျဖစ္ပါတယ္....၀ယ္ရတာလြယ္ပါတယ္...

ျပီးရင္ေအာက္ကပံုအတိုင္း ဆက္သြယ္လိုက္ရင္ေတာ့ +5v charger ေလးပိုင္ဆိုင္ျပီေပါ့










You'll only need a few components in order to make your own battery-powered USB charger. As with all builds involving electricity, you'll need some knowledge of electronics. This is needed as you don't want to fry your devices in the process. You'll need a basic 9V battery, so make sure that you have the right connectors. You'll need a female USB port that you can salvage off an old computer.

The positive lead from the battery goes to the regulator's left leg, and the regulated 5V goes from its right leg to the left pin of USB port. The ground wire goes from the battery to the middle leg of the regulator, then continues onto the right pin of the USB port. A glue gun will do wonders in sticking it into some kind of casing. It's quite compact and easy to carry around.

There are some inherent limitations, including the ones that are put in by the manufacturers of your devices, but this shouldn't discourage your from trying out this simple and effective way of charging up your gadgets by using a few dollars worth of equipment. Possible improvements include using a larger array of batteries, like 5 D batteries.
