I'm one of those guys that always runs out of power on my cell or laptop when I need it most. Can anyone tell me how to build a USB circuit so I can recharge my laptop or phone from a set of solar panels when I'm in the field? I live in a remote area and it's terrible to not have power when I need it. Laptop batteries are a small fortune and inconvenient to drag around with me.
How do I figure out how much / or many solar panels I need? I'm going to use those 2.3 v solar panels that are on the solar lights for my garden. How do I figure out how many do I need so I won't under or over charge my batteries?
Second question: Does anyone know about a "wireless" USB connector coming out soon? USB 3.0
Thanks
