Is there a problem if I just use the AC adapter I have? Will it burn

Yes. You'll either blow its fuse, or cook it. Get the right adapter.

No. It's something like turning on the kitchen sink. The city water
company has enough capacity to fill 10's of thousands of sinks at the
same time, but only the amount of water your pipes and faucet will
carry come out of your faucet. Over-capacity is not dangerous.

Water company capacity (maximum output, quantity of water per unit of
time) is analogous to maximum amperage.


OTOH, water pressure that is much too high can make weak pipes leak or
burst, which is analogous to burning out an electrical device. (I
think it can make the toilet tank keep filling after it is full, and
maybe other things.) Water pressure is analogous to voltage.
