Apparently, since the Book 3 has come out, Microsoft doesn't sell the original Book 2 chargers anymore, so now we have to get it off of someone that is sponsored by Microsoft and is compatible with the model.
Have to say, there are no shortages of 102 watt surface chargers available from Amazon and elsewhere that are less than half the price of the official Microsoft one and they are just as reliable. I've had Microsoft chargers fail as often as the cheap ones.
