This is the weirdest cable I own. It's a retractable USB-C 60W cable with Lightning and USB-A adapters attached. I don't know what its data speed; it might be power only.
The max wattage reduces depending on which adapters you have attached.
I have kept it in my bag as backup charger for a few years. I think I've needed to use it maybe twice.
Does anyone understand why this USB-C PD AC adapter (left) can't charge this USB-C PD power bank (right)? They both claim 5V, 9V and 15V at 3A plus 20V at 2.25A, shouldn't they be able to agree on at least one of those?
I don't mean the power bank charges slowly FWIW, I mean it doesn't charge *at all*. Though it lights up to indicate it's powered. The AC adapter powers everything else just fine and the power bank can charge from other things just fine.
MacBook NeoのUSB-Cポートは映像出力や高速データ転送が可能なUSB 3と充電やマウス接続などに適したUSB 2仕様のポートがあるため、USB 2側にディスプレイや高速ストレージを接続するとUSB 3側を使うよう通知が表示されるように。
USB-C ports: How they work on the MacBook Neo
No Mac currently has as few ports as the MacBook Neo. Dongles will be needed for many applications – but it could have been worse.
