Mr. Buzz is a solar powered USB charger in a cup! The lightweight and flexible PowerFilm solar panel charges up the 2400mA battery pack so you can recharge your USB device even without the sun.

What can I charge with it?
Mr. Buzz uses a 'Type A' USB Jack, the same style USB jack that's on your computer, so it will physically connect to nearly any USB device. That said, some devices don't like being charged by a battery pack or solar panel.

Usually, if you plug your device into your computer and it needs to install software before it begins charging, it will not work. Here's what I've tested:

WORKS:
Apple iPod: Mini, Nano, Shuffle 1G/2G, Classic, Touch, iPhone
Creative Zen Micro
Nintendo DS (with an adapter cable)
Microsoft Zune
ATT Fuze, aka Touch Pro
Motorola S9-HD
PS3 Bluetooth Headset (in holder)
Verizon PPC 6700 (HTC Apache)
Creative Vado
Creative Zen Stone

DOESN'T WORK:
So far, any device that doesn't work with my usb wall charger will also not work with Mr. Buzz. I've tried;
PS3 Wireless Controller
Xbox 360 Wireless Controller

How long to does it take to recharge?
It should take the same amount of time as if it were plugged into a wall charger or any other device. To charge my phone from dead to 75% takes 90 minutes (same as a wall charger).

How much juice does it have?
Total power storage is about 2,500 milliamps. This is enough to charge my phone (which has a 1,300 mA battery) about 2 full times. An iPhone's battery is 1,200 mA, so you should about 2 charges, too. Smaller devices (like a shuffle) will recharge many, many times.

What batteries should I use?
You should only use rechargeable AA batteries (Nickel-Metal Hydride). With 4 batteries, Mr. Buzz provides 4.8v-5.2v

Do I have to use batteries?
Yes - the solar panel slowly trickle-charges your batteries, and they aren't large enough to directly power your USB device.

You'll need a few tools to build this project
(1) A soldering iron & solder (Soldering Tutorial)
(2) Diagonal Cutters

You'll also need a 4xAA Rechargeable Batteries. The project takes about 20 minutes to build.
