Review on CyberPower CSP105U Professional Dual USB Power Station – High-Quality, Black by Sean Perry

I've never had time to write a review or exchange this product until now: I gladly gave it to my husband but there can only be a USB port charging is used immediately. When I connect two devices to charge at the same time, only one charges. At first I thought these were just charging cables and replaced them with three others. The problem continued. Then I thought it was because I was charging two iphones at the same time and was trying to charge the headphones instead. The problem is still not resolved. I keep this on my bedside table now to only charge 1 phone at a time. Fantastic concept/potential for a great product but I am disappointed that I may have received a defective unit.
