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

Tools:

  • pair of pliers
  • soldering iron

Materials:

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

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 .

    Yes, in series. If you will use a resistor, you must use a small power resistor. For example 10k or 5k

    Hey, very nice work!

    I noticed in step 4 you bounced to Spanish for a bit! :) Some people share steps with text in both English and Spanish, which is a great idea if you wanted to do that.
