Maximize power and USB charging capabilities while minimizing the cutout footprint on the desktop by simply drilling a 2-5/16" diameter hole and inserting the rectangular power and USB hub station from above and hand-tightening the locking collar underneath. Two power outlets rated 15A/125VAC and two dual 2 amp USB chargers can charge up to four mobile devices at once, making this an ideal fixture for use as a public charging station or a private workstation with multiple users. Custom insert tops and graphics available.
