Dynamo Hub Or Solar Panel

My preference is to use dynamo hubs.

Dynamo hub or solar panel.

The two products i m comparing specifically are the shimano dynamo hub and the guide 10 goal 0 solar panel. The solar panel folds down quite well still a little bulky but it easily fits in my frame bag or is left exposed when needed. My biggest concerns are the rolling resistance on the hub and the availability of sun. However the dynamo hub seems more reliable for generation and doesn t rely on having a rack or flat surface on which to mount it.

If you have dynamo lights already do yourself a favour and grab a power supply to start charging your devices. I m looking at around 2k aud for wheel sets myself and partner to be built with dynamo hubs while not a major issue i m concerned i ll get little in the way of mah for my investment when i already have a solution. Just like a laptop panels and batteries are not lightweight or space savvy. If you want to charge your laptop on the road solar panels and batteries are your best option.

Solar solar has become more and more accessible with many brands popping up and competition means good prices and more features. A 20w would recharge a 20000mah powerbank 2 3 times per sunny day. You can choose different sizes for different power a 10 15w panel is more packable and will keep most users well charged.
