Me and my partner are thinking of making a solar battery charger for a phone. This would help many people who don’t have any power in their area but have phones that  charged. This would also need to be charged. This could also help hikers charge their phones. If we are successful, this could help some people in country that need power. We will use solar panels and a battery in a 3-D printed case. We are thinking about making the case into a phone case so that it can attach to your phone and charge it as well. This would help make it more compact and more  portable. Our hash tag is #star battery
