I raised a similar question some time ago about charging a phone with a solar charger or had cranked charger.
I later found that there are a number of USB Data line configurations for charging smartphones which vary depending on which region the phone was made.
To combat all these possibilities I ended up finding the below website explaining how to build a charging line bridge to get around the different charging configuration problems presented by various phones. Link below.

However, after building this, the phone still struggles to charge so I'm not thinking that the current just isn't stable enough.
I have been using a hand cranked generator and a solar panel to charge the phone and struggle to get a 1% rise in power.
How do I stabilize the current coming from my various chargers (solar and hand cranked)? I seem to remember someone mentioning bridging the + and - lines with a capacitor but surely there's more to this than that. What does a controller do? Is that what I need to get this to work?
Thanks. I'm a little stuck on this.
