As seen on CNN! Build your own backup battery and recharge it with the sun! This Solar Boost Bag uses a PowerBoost 500 Basic, a solar lipoly charger, slide switch, and 2000mAh rechargeable battery, all housed in a 3D printed enclosure.
I’m on Dhani Jones’s new CNN series “Be a Champion,” where we soldered up a solar bag circuit together, and I even surprised him with an EL wire bowtie. Check out the video on the CNN site as well as the rest of the video series!
Before you begin, read through the following guides:
For this project, you will need:
- USB/DC/Solar Lithium Ion/Polymer charger kit
- PowerBoost 500 Basic
- 3D printer with filament
- A large solar panel or a medium solar panel
- 2000mAh lithium polymer battery
- 2.1mm DC Barrel Plug
- slide switch
- A sturdy handbag or backpack
- soldering tools and supplies
If you’d rather build a light-up bowtie like Becky made for Dhani, we’ve got a tutorial for that too!
