Charging your phone while cycling – willcycle.blogspot.com

Some consider them a curse, but it’s very hard to argue against the very real benefits smartphones bring to our lives. Whether it’s accessing social media, or taking a photo, most of us are using our phones all the time, and that simply means it’s quite easy to totally drain your phone’s battery during a normal day’s usage.
When we throw battery-sapping uses, like using GPS, or the camera, into the mix, then your phone’s battery life off a single charge could be reduced to just a few hours. Add to that the fact that a good bike ride can be far longer than just a few hours, and the scale of the problem becomes instantly obvious. And that’s before we even think about multi-day rides!
So, what practical steps can you take to guard against having a flat phone battery? Well, you really only have two options: use a power bank, or use a dynamo. 
We’ll give it a minute for the laughter to die down, after that one person at the back suggested solar charging as an option anywhere outside of the Namib desert.
