DIY $3 Solar Powered Small Electronic USB Charger
If you are looking to improve your DIY skills and save money at the same time this easy project is for you. This little garden light hack allows you to charge small electronic devices like phones, MP3 players etc.
The cool thing about this little project is you can keep the charger in the sun during the day and at night plug it in and it will charge your devices from the batteries already in the solar device.
I have a few of these I keep in my camping tote, I just let them soak up the sun and then I know I have a great power source to charge my camera and iPhone when ever I need to.
