I have maybe a 20 drones so far. All but 3 or 4 of these the batteries are charged via usb port. I keep most of my drones out in my studio but have to take the batteries into the house to plug into the computer usb. Is there a device that works on AC with a usb port that can charge all these different batteries?

And these things put out the same amps or watts or whatever as a computer USB port does and are safe??????
