I will also hook up a USB connector plug to charge my BlackBerry Phone and Ipod. Most USB devices are rated 5v , so with this circuit like this, you will never need to deal with a solar charger to charge your phone, GPS, ipod, recharable batteries, or to power any standard USB device.
Please refer to Step 1, Step 2, Step 3 & Step 4 for further details..
FYI: This is a work in progress, and I will update my instructions as my project progresses. Please bear with me given my hectic schedule and feel free to contact me if you have questions regarding where to get the parts or accessories. And don't forget to leave feedback and suggestions.
Thank you for visiting & Have a Happy and Safe riding!
