Getting one for my wife to fast charge her MBP in her Tesla, which is basically an unlimited battery (from the perspective of the laptop). Hoping it works thru the cigarette port w/o overheating too much; the newer Teslas actually run on a 14.4V system (vs 12-13V), which should drop the amps a tad if this thing actually provides 100W. Plan on doing full PD testing, if anyone's interested I can post results here.

The listing for this contains some discrepancies, I am curious what the actual capabilities are. Title says 120W, some of the images show 120W but then also show 130W. Another image says it has 3 independent charging chips, which would imply to me that all 3 of them together could output their power at max, which would be 153W, though there's nothing else to indicate that it would. Because of it being a car charger there's also the possibility it could do that but then it was limited to prevent popping fuses, who knows.
Would be curious if 120W is the actual max when you do your testing.

It came and so far I'm impressed. I was expecting a far cheaper product, but I tested it with an MBA (couldn't get my wife's MBP as she was working) and got 67W measured, which is possible to be the MBA's USB-C's top speed. This is using the included cable, which isn't braided but is otherwise of seemingly good quality. Measured 118F after ~15 min of charging at said wattage, and that is by probing all around to get hottest spot, it felt surprisingly okay to the hand. It's possible that it might get a little hotter on standard "12V" systems, like I said, current Teslas use ~14.4V which is ~10% more than normal 13.xV of normal 12V systems, which should result in a commensurate drop in amps (amps being the primary driver of heat).

I took some pics but can't seem to upload directly, will see if I can link later if anyone's interested. Overall, especially for the price, I'm happy!

I got this yesterday. I haven't tested its charging abilities yet but it is vented underneath and not as wide as my 17xW Anker one. However, I tested the cable that came with it and it's super low resistance - as good as or better than the anker and baseus ones I just bought as Slickdeals, though those are longer.

Mine came today and was clearly a used product in an already open box with stickers removed.

It is also an older model. Says 60w on the side
That only has a single USBC and a single USB A
Device is scuffed up and scratched
