It has been four years since the release of the 13-inch MacBook Pro 2018.
And we can see the 14-inch MacBook Pro and MacBook Air adopted the next-generation design.
But this MacBook Pro still seems to be stuck four years ago.
After switching to M2 chip, can it be more powerful?
Let’s take a look.
Firstly, both laptops are equipped with a 13.3-inch retina display.
The USB-C charging ports have been reduced from four to just two.
But the standard has been upgraded from ThunderBolt 3 to ThunderBolt 4.
Compared with MacBook Pro 2018, the new model changed back to scissor switch keyboard.
And it’s the only model that still retains the Touch Bar.
It comes with a 67W charger, which has been taken apart by us before.
You can click the upper right corner to check that.
The charging cable inside the box is pretty long.
About 2m (6' 6.74'').
And it’s also a 5A cable.
Next, let’s start to test its charging performance.
Firstly, let’s use different chargers to charge this laptop to check its charging compatibility.
The charging power is quite stable since it also adopts the same PD protocol.
You can simply find any PD charger from 20W to 140W to charge this laptop.
And although it comes with a 5A cable. The current won’t be over 3A during the test.
So, a 3A cable is enough for this.
We’ve also made a chart for you. You can pause to take a look.
As we mentioned, it can support any PD charger from 20W to 140W.
So, we used four different chargers to charge this laptop fully.
Not many people will use a 20W charger to charge a laptop
But what if there is an emergency?
So, let’s see how long it’ll take.
The charging curve of fully charging MacBook Pro with Apple 20W charger
can be roughly divided into two parts.
It takes about 4 hours and 8 minutes to charge fully, and the peak power is 18W.
Then, the charging curve of Apple 30W charger can be roughly divided into three parts.
The voltage is maintained at 20V,
while the peak power is 28W.
It takes about 3 hours to charge fully.
And then, the charging curve of Apple 67W charger can be roughly divided into four parts.
The voltage is maintained at 20V, and the charging power varies with voltage.
It takes 2 hours and 16 minutes to charge fully, and the maximum power is 57W.
And the last charging curve of Apple 140W charger can be roughly divided into four parts.
It takes 2 hours and 10 minutes to charge fully, and the peak power is also 57W.
Finally, we put all those charging curves into the same one.
We can see the charging curve is directly proportional to the charger’s power.
In some cases, we can use the 20W charger to replace the original 67W charger,
but the charging time will be doubled.
And we can also use the 140W charger to replace the original 67W charger,
which is only 6 minutes faster.
Well, that’s all charging tests for this MacBook Pro.
The charging performance has always been very stable regardless of compatibility
and fully charging tests.
Besides the charging performance, we should pay more attention to the USB-C ports.
Since there’re only two USB-C ports, the USB-C Hub is more necessary for this laptop.
Ok. That’s all for today’s video.
