“Mfgr desc says "USB-C ports delivering a total of 67W (with a maximum of 35W for USB-C)". If I'm charging 2 USB C devices at once, capable of accepting 27W ea,, is each one only being charged at 17 watts?”

Short answer: The original answer to your question that says each USB-C port outputs 35W max when 2 USB-C devices are plugged in at once is obviously *Wrong* by simple math (as 35W x 2 = 70W, and as evident in this device’s name, 67W is the total possible wattage when multiple ports are in use) A device plugged into USB-C port #1 will charge at a maximum of 35W, and in the most *likely* case that this model’s basic design is similar to the newer "Anker 535 Car Charger (67W)" model (see “Details:” at the end of this post/answer) this older Anker 335 model will charge the device plugged into USB-C port #2 at a max of 67W-2W-35W=30W max. Again, it’ll most likely output at 35W maximum on USB-C port #1 and 30W maximum on USB-C port #2 (with no device plugged into into the USB-A port). In your case where each of your USB-C devices are capable of charging at a max rate of 27W, when they are both plugged into both of this Anker 335 model’s USB-C ports, it’s most likely that they’ll charge at a max rate of 27W each. (Because charging on USB-C port #1 means that a 67W-2W-27W=38W maximum total wattage remains for the combined simultaneous use of the remaining USB port #2 and the USB-A port, and since you’re not plugging anything into the USB-A port, the total possible max wattage possible is 35W on USB-C port #1 and 30W on USB-C port #2, and your device’s 27W < 30W.) Details: Anker’s website shows for its newer version of this charger, the "Anker 535 Car Charger (67W)", that when its 2 USB-C charging ports are in use while the USB-A is not in use, it will output: 45W maximum on USB-C port #1 and 20W maximum on USB-C port #2. (interestingly, USB-C port #2 and the USB-A port will output at the very low rate of 9W maximum each when devices are plugged into those two ports while nothing is plugged into USB-C port #1.) Can deduce from this that when multiple devices are plugged into the Anker 535 charger, it will in actuality output not at a maximum of 67W tota
Sorry, there was a problem. Please try again later.This charger is capable of delivering 35W on each port, if your device being charged accepts a max of 27W then that is the power it will deliver on each port, since it is below the 35W that is capable of delivering at a given time.
