Picture of Home-Made LED Flashlight USB Charger (12V 1.8Ah Li-ion Battery!)

This is a project is powered by a 12 VOLT 1.8 AMP hour Lithium Ion Battery that powers two flashlights (warm and cold), USB charger, And 12 VOLT output.

This isn't a step by step tutorial because anyone can build it to fit their own needs, I'm just showing how I built it.

There will be a video at the last step showing some of the features I made, I do recommend watching it, But it doesn't include all of the features that are shown here

Step 1: This Is the Battery

Step 2: LED's

These are the led's I used:

Step 3: A Look Inside

This is how the inside looks:

The battery, USB and 12V Outputs, Switch Connections, And the PCB.

Step 4: Outputs

Picture of Outputs

If you hover your mouse over each output there will be text that explains each one

The button switch has to be pressed to activate the outputs (press again to disconnect the outputs)

Step 5: Main Switch

Picture of Main Switch

This is the main button switch has to be in the on position. Nothing will work if the the main switch is off.

Step 6: Mounting the LED's

Picture of Mounting the LED's

The LED's are mounted to a heat sink (that was sawed in half to fit) with thermal epoxy. The heat sink was then hot glued onto the outside case with hot glue (It doesn't heat up enough to melt it).

Step 7: Thank You

There are no viruses in the video (Scanned With Avast)

I wasn't able to compress the video file, But if it is viewed on a computer the downloading process shouldn't take too long

Cool project. But I don't prefer mounting the heat sink using hot glue. If its being used for a long time then there is a possibility that the heat sink may not be held firmly.

Yonatan24 (author)smandal132015-08-15

That's right but the heatsink barely even warms up when both LED's are on...
