1. How to make a solar phone charger with an enclosure

tools:

  • plastic enclosure
  • TP4065 charging board
  • USB boost converter
  • 18650 battery holder
  • new 18650 battery or salvaged battery from used laptop
  • 5.5v to 6v solar panel
  • IN4148 diode

other tools:

  • enclosure
  • drill
  • hobby knife
  • foam cushion
  • scissors
  • glue
  • mounting pads

Step 1: Making slots for USB port

drill 3 holes side by side and join them, then smooth the edges using a hobby knife, repeat this process until the USB port fits the slot.

Step 2: Placing the boost converter

cut some foam cushions for placing the boost converter, then stick the foam cushion using glue, repeat the same process for the TP4065 charging board, then use mounting pads for sticking the boards, after that apply hot glue surrounding the USB port and press slightly to align with cut out slot

Step 3: Passing the solar panel wires

drill holes into your enclosure for passing the solar panel wires.

Step 4: Stick the battery holder

stick the battery holder using hot glue into a suitable place in your enclosure

Step 5: Connecting the panel wires

solder the diode the black band indicates negative terminal then solder the red wire to the positive terminal of the panel and solder a black wire to the positive terminal of the panel

Step 6: Insert the solar panel wires

insert the solar panel wires using the holes which you made before, then stick the solar panel using hot glue, after that press the panel until the glue dries out.

Step 7: Connect the panel to the TP4065 charging board

solder the red wire of the panel to the solar panel +Ve connection in the TP4065 charging board and then solder the black wire of the panel to the solar panel -Ve connection in the TP4065 charging board.

Step 8: Connect the battery holder to the TP4065 charging board

solder the red wire of the battery holder to the battery +Ve connection (B+) in the TP4065 charging board and then solder the red wire of the battery holder to the battery -Ve connection (B-) in the TP4065 charging board

Step 9: Connect the charging boost with the boost converter

solder the boost converter +Ve terminal to the TP4065  out + and solder the boost converter -Ve terminal to the TP4065  out -, try to use a cable tie to finish the meshy wires.

Step 10: Insert the battery

The last step is to insert our 18650 battery, spring side is the negative terminal of the holder, so be careful to attach the two negative sides and the two positive sides.

Step 11: Enjoy your DIY solar power bank 

Your DIY solar phone charger is now ready, enjoy it.

tools:

  • 12-48V DC to 5V DC Car charger component board (x1)
  • Female USB cable end (x1)
  • Mini Solar Panels (x5)
  • Some silicone coated wire
  • Red LED (x2)
  • Yellow LED (x2)
  • Green LED (x2)
  • 1k resistors (x6)
  • Popsicle sticks (Between 10 & 20)
  • Two pairs of velcro straps
  • old shorts (x1) 

other tools:

  • scissors
  • glue

How to make a diy solar power bank at home

Step 1: Connect your 5 solar panels

Take your five solar panels and lay them out and you are going to solder them together using the flexible wire, make sure you are wiring the panels in series which is a positive 2 negative connections.

Step 2: Folding the solar panels

I decided to use a pair of old shorts for the material for my folding solar panels. We are going to shove a flattened cereal box into one of the pants which are going to help us to easily draw a line across where we are going to cut.

Once you finish cutting out the piece of fabric you should be able to fold it in half.

Now you are going to sew the piece of fabric together.

Step 3: Connect a wire to the panels

take a long section of wire which is about the length of all our panels and solder it to the end of one of our panels this will be running throughout the whole solar panel strip.

solder on a short section of wire to the other end of the strip of panels.

Step 4: Glue the panel into the fabric 

now it’s time to glue the strip of panels to the piece of fabric,

Step 5: Making a simple box

using the Popsicle sticks you are going to make a simple box that is going to sit at the end of the fabric and hold the rest of our charging components.

Step 6: Install our component into our box

After we ade the box now it’s time to install our components on it, so use the glue to install the Female USB cable end and the charger component board and be sure to solder the output wires from the charging component to the female USB port.

Step 7: Connect our panel to the charger

you see those two wires sticking out from the solar panel, connect them up to the input wires of the charger.

Step 8:Making a charging indicator

its an optional step but it’s important to know if your charging process is working well or not so we are going to make a charging indicator

solder the 6 LEDs and the 6 resistors we have into a wire, now solder on a couple of wires to the charging indicator one to the side where all the resistors are, and another wire to the other side where the LEDs connected to after you get it ready now its time to fuse it to the connection of the female  USB port.

Step 9: Making a roof

You are going to close up all the components that sit in this box by making a roof, use the popsicle sticks to make it, and make sure to superglue the box to the fabric.

Step 10: Enjoy your DIY phone charger

Now you have finished all the steps and your DIY phone charger is now ready. All you have to do is to test it and enjoy it.
