Universal 200W USB charger

What will happen if I use A 5V 1A charger to charge A 5V 2A device?

If you use a 5V 1A charger to charge a 5V 2A device, the device will charge slower than it would with a 2A charger. This is because the 1A charger can only supply half the current that the device is designed to take in for charging. This will not harm the device, but it may not charge at all if it's on and being used while it's plugged in, as the device may use more current than the charger can provide.
