Hello everyone,
I noticed on the “new” AC200P from amazon (unwittingly purchased from a third-party seller) that the charger did not look like a T500 charger I throught was included (Bluettin branded with a fan), so I sent a picture of the charger to the Bluetti support team.
I was told that this was a T400, one of the two options for the charging brick that could be shipped with an AC200P, and pointed out that they could not honor the warranty for a third-party (unauthorized) reseller.
It seems the charger does not have T400 or Bluetti written on it at all, and ther is a charging light that I thought was only for the T500 charger.
