Does Anker even proofread their Amazon listings?! How can you list two vlaues that contradict each other? If you get two different measurements, measure a third, fourth, fifth, and sixth time, don’t just say two different Possible dimensions.
Who actually gives a crap about a products dimensions when it is something as small as a wall charger?? Not saying that there are’nt people out there… but most normal individuals do not care about a products dimensions when it is something that small.
It’s common for a few different manufacturers, left hand not knowing what the right hand is doing situation (aka design department not talking to sales etc). As you said just email, not exactly worth a venting session IMO.
