Enjoy convenient cordless charging of mobile devices. The KwikBoost EdgePower™ desktop charging station system is a total solution for laptops and mobile devices in workspace and classroom environments. EdgePower eliminates extension cords by putting power right where you need it. Featuring enough power to fully charge a typical laptop up to 2 times, a standard Chromebook or tablet up to 4 times, and an average smartphone up to 14 times, the EdgePower’s Rechargeable Battery provides hours of uninterrupted productivity. When it’s time for a recharge, simply swap it out with another Rechargeable Battery and keep working. To create a complete system, the Rechargeable Battery requires a KwikBoost EdgePower Clamp-On Desktop Charging Unit. You also need your choice of a Single Battery Charger, 3-Bay Base Charging Station, or 9-Bay Base Charging Station (sold separately or in bundles).
