This is a USB charger from ASUS. Although it is a new, unused item, I tested it to make sure it works before listing it, so I powered it on once. The outer packaging film has some scratches. Please consider this item with the understanding that it has been stored at home. - Brand: ASUS - Model: AD2068320 - INPUT: 100-240V 50/60Hz 0.5A - OUTPUT: 5V 2A or 9V 2A
