Your Questions About Solar Generators Portable

anyone familiar with the FreeCharge Weza portable power source?

i’m looking for anything that runs on dynamo or human power. i want to disconnect from the grid but solar panels and wind generators ar sooo expensive. all i need to power are a few small appliances. and maybe an electric bike that i’d like to get. thank you; links appreciated
