is using a laptop with it's battery removed, and using the adapter instead safe?

Hello Steven,

I can't confirm this information, but, in theory, it should work.

But, I do recommend you confirm it with Asus Support since I am not sure this can cause harm to the computer.

thanks for the reply, but are you able to tell me base on your opinion? if not then no problem.

I am sorry to hear that.

It's best you confirm this with ASUS.

I'd suggest that you buy a US charger. While you might be able to get away with using an adapter it does say to use it without an adapter for good reason. Using it with an adapter can shorten the life of the battery and even be dangerous (explosion, fire,
shock). Using it without an adapter on US current would definitely be dangerous too.

It's not really worth trying when there are plenty of safe, cheep chargers available in the US.

Yes, it is safe. The laptop has circuitry in it which will prevent overcharge of the battery.
