Introduction: USB Light for Cell Phone Portable Charger
Most of us have in the backpack a portable charger if your phone runs out of battery. these portable chargers have a USB connector so it can give you many applications to these sources of energy.
Step 1: Tools and Materials
- pair of pliers
- soldering iron
- portable charger
- male USB cable
Step 2: USB Cable
Short rubber sheath that protects the USB port leaving only the metal part with electric cables. just let the power cables ( black and red) as shown in the picture.
Step 3: LED Connection
with the iron connects the USB port with LED in their respective polarities. I suggest placing a small resistance if you have any fear of accidentally melt the LED
Step 4: Sealed
Step 5: Connecting Portable Charger
As it is ready our little device you connect to the laptop charger and if all goes well the LED will illuminate and we have a USB flashlight for portable chargers
Step 6: Alternative Design
is the option of using two LEDs instead of one connected in series becoming more efficient system operation .
