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.

Tools:

• pair of pliers
• soldering iron

Materials:

• portable charger
• soldering
• LED
• male USB cable
• Tape

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.

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

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

is the option of using two LEDs instead of one connected in series becoming more efficient system operation .
