Not only do you not see any identifying information, but itвЂ™s only giving 55W to the computer, which categorizes it as a non-charging plug, denoted by вЂњ Charging: NoвЂњ. But when we plug it in and check the System Profile information, well, the truth is shown: Now IвЂ™ll try a third-party 60W charger that should work just fine, at least according to the vendor.

Note that the correct Apple cable and a lower wattage charger reports as youвЂ™d expect: In other words, a faster charger, but a slow charge.

You can see the problem, right? 87W charger, but only 60W coming in to the computer for charging. Now, letвЂ™s try swapping out the Apple cable for a third party USB-C cable and watch what happens when we relaunch the System Report: Most importantly, though, look at the вЂњ Wattage (W)вЂќ field, which shows that the computer is getting 86W of power, a fast charge for this device.

That shows itвЂ™s a proper Apple 87W USB-C Power Adapter, and even shows its serial number.

Click on that, then scroll down on the left side to find the вЂњPowerвЂќ entry. Key to realize: the wattage specified isnвЂ™t necessarily the wattage that the computer receives when charging.

In fact, I learned some things about charging systems as I was writing this post, so I should thank you for your original question! First off, the key variable is wattage and itвЂ™s calculated easily as amperage * voltage.В Apple has four different chargers depending on your notebook or computer model: 29W, 45W, 60W, and 85W varieties. Even with an Apple charger, if you have a USB-C system like I do and use a third-party cable, that cable itself might drop the wattage down and slow down the charge.

Cables, chargers, both can have a surprising effect on your power and charging experience with a Mac system in ways that are not at all obvious. Ah, youвЂ™ve opened up a PandoraвЂ™s Box of complexity when you move to third party anything in the Apple ecosystem.
