Just in time for the Green Cup Challenge, Ohrstrom Library has two new solar battery storage units available to recharge your small devices. Next time you check out a phone charger at the front desk, use the stored power of the sun to recharge your phone or tablet! 🌞📲#ohrstromlibrary #greencup #greencupchallenge #solarpower #solarchargers #batterybackup #environmentalstewardship #gosolar #phonecharger
