I have Anker 65W and 100W GAN charger and both should work fine with the FW13 although one reviewer reported that a 65W charger (FW’s own) cannot keep up with power consumption during intensive tasks so the laptop keeps flipping between AC and battery power. General consensus seems to be get a 100W charger to be safe, especially considering they’re not much bigger than 65W ones.
