Introduction: 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

A high power 12 VOLT 1.8 AMP hour battery

Link to eBay

The second picture shows the charger

Step 2: LED's

These are the led's I used:

Cool LED

Warm White LED

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

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

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

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

Thank you for watching!

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

What a wonderful 'ible!!

Thanks! This is an old I'ble, though I have better ones now... :)

EXELLENT IDEA SIR! JUST A CORRECTION .... THE BATTERY YOU MENTIONED YOU TOLD 12 V 1.8 AMP SHOULD IT BE 1.8AH CORRECT ME IF I MISS SOMETHING OBIVIOUS..:)

Yep you're correct, I missed that

Nice flashlight!

Exactly 12 hours have passes since I clicked the "upload" button, And this Instructable has hit over 1K views!!!!
Thank you everyone for the support!!!!!!!!

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.

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

Nice and versatile flashlight.
