So I'm trying to help a friend find a power supply for her Gateway T-6345u laptop. Since Gateway barely exists has shitty support, I'm looking for 3rd party stuff. Amazon has a grip of cheap Chinese versions but I'm having trouble finding one with the exact electrical ratings as the original. Basically, I see a bunch where the input voltage is correct, the output voltage/amperage/wattage is all correct, but the input amperage is higher/lower. Not everyone lists the input amperage, so I'm wondering how important that actually is. If the output specs are correct, does the input amperage matter?
