Yes that makes sense.But the current would matter when it wants to draw more than you have available, right?
Lets say it can recharge at 12V, 2A so 24W but you give it 12V, 1A so 12W. It will recharge at 1/2 the speed that it is capable off.
And then lets say the device that you plug into needs 24W, you'll drain it faster than you charge it...
This is why I say the "same or slightly more" current than what is required.
Yes I think so. Well, not sure about the Voltage, but current should split according to how much is being drawn by each device. After all that's how any power supply works eg. multiport usb chargers have a total current that they can handle across all the ports.Some people use split cables on these ports . If you split them, I guess the voltage stays the same but the current is split between the 2 devices if the 2 devices both pull the same amount of current. Is this correct?
