Why build a phone charger

chargingCharging with a laptop battery

When going to a festival, you obviously have to bring your phone in order to find your friend. Also, more and more festivals make specialised festival-apps making it a bare nesessity.

Modern day smartphones do, however, need charging every second day so one needs to find a clever way of keeping the phone topped up. Either you can pay for it, or you can make your own solution. I chosed the latter, and found a pretty highly effiecient way of doing so.
