I’m currently touring on my push bike and want to improve my solar setup, but have no idea what I’m doing!
I need to power the following devices:
I bought a small panel with a built in 2000mAh battery (PortableEnergy from Maplin), which can charge all of these with USB – the panel is about 4cm by 10cm, not sure what wattage. It manages just about ok with the phone, struggles with the PSP and not a chance with the batteries.
I’m looking to upgrade to something a bit bigger, but obviously as light as possible, as I have to carry it on my bike. I could get a dynamo charger, but I often stop for several days and don’t want any extra drag when I’m riding.
Sorry these are such basic questions, but I haven’t had any luck finding answers to any of them.
