Q: 1. Hello, I would like to know what is the maximum amount of Amps that this unit can carry? I plan to connect it to an APC UPS that is designed for 110 Voltage Input but I am residing in the Philippines and the Voltage here is 220 Volts. I then plan to connect up to 5 external hard drives to the UPS. I know they draw very low current but I need to know to be safe before purchasing. Any help would be greatly appreciated. Thank You. John
