Hi, guys. Welcome back to today's video.
We've taken apart the 20W mini charger and all-in-one 100W charger from UGREEN.
And today, we gonna take apart another 65W charger from UGREEN.
It's printed with GaNX 65W on the front.
And four features are below.
Three-port, foldable, wide compatibility, and smart protection.
Flip to the back. Model is CD244.
It can support wide-range input voltage.
The USB-C1 and USB-C2 are the same.
And it can support up to 65W and a set of PPS.
The USB-A can only support up to 22.5W and Huawei SCP protocol.
And the total output power is 65W.
Let's open the box. It contains the charger and manual.
This is a rectangular charger,
which adopts black and is printed with the logo of the UGREEN and 65W.
It adopts foldable prongs and is equipped with two USB-C ports and a USB-A port.
The USB-A port is purple and can support Huawei SCP protocol.
The specs info on the side is the same as that on the packaging.
The size of this charger is about 67x40x31mm (2.64x1.57x1.22 inches).
So, the power density is about 0.77W/cm³.
And it's pretty small.
The weight is about 119g (4.2 oz).
ChargerLAB POWER-Z KM002C shows the USB-C ports can support Apple2.4A,
QC2.0, 3.0, QC4+, AFC, FCP, SCP, PD3.0 and PPS protocols.
The USB-C ports can also support five fixed PDOs and a set of PPS.
And then, the USB-A port can support Apple2.4A, QC2.0, 3.0, AFC, FCP, and SCP protocols.
After testing the protocol, let’s use it to charge different devices
and check its actual performance.
Firstly, let’s test the USB-C port.
Those Android devices can support PPS protocol.
So, the power can reach 60W.
And for MacBook Pro, the power can reach 63W.
Here are the compatibility test results of the USB-C port.
We’ve made a chart for you.
And then, let’s test the USB-A port.
Since it can support Huawei SCP protocol,
most Huawei devices can be more than 20W.
But a Huawei cable is necessary.
We’ve also made a chart for you.
For most Android phones, the power is between 15-20W.
The power of the iPhone is around 12W.
When we use USB-C1 and USB-C2 to charge two devices, the power will be 40W and 20W.
When we use USB-C1 and USB-A to charge two devices, the power will be 40W and 20W.
When we use USB-C2 and USB-A to charge two devices, the power will be 10W and 10W.
Finally, let’s use this charger to charge two mobile phones and a laptop at the same time.
They’re 40W, 10W, and 10W, respectively.
Since it can support up to 65W,
which is enough for some laptops.
So, we decided to use it to fully charge the MacBook Pro 13”.
Here’s the charging curve.
It can be roughly divided into four parts.
The peak power is 44W at 48 mins.
And it takes about 2 hours and 23 minutes to fully charge the MacBook Pro 13”.
And then, we found it can reach 34% in half an hour and 66% in an hour, which is pretty stable.
Most people won’t remove the charger after charging their phone.
So, is there any power consumption in this case, and how much is it?
We can use the power meter to test it.
The no-load power consumption of the charger at 220V 50Hz
is 0.285W, which is about 2.49KW·h in one year.
And the no-load power consumption at 110V 60Hz is 0.233W, which is about 2.04KW·h in one year.
The charger is essentially a conversion device.
So, energy will be lost in the process of converting AC to DC.
So, here is the conversion efficiency test of the charger.
The conversion efficiency varies from 84.32% to 91.49% at 220V 50Hz.
The conversion efficiency varies from 84.77% to 89.91% at 110V 60Hz.
Most chargers adopt switching power supply currently.
There will be ripples in the output current.
The lower ripple means better quality.
Firstly, here’re the differences in ripple between two different ACs under no-load.
When the output is 5V 0A, the highest ripple is 22 and 24mVp-p.
When the output is 12V 0A, the lowest ripple is 10 and 12mVp-p.
Then, let’s see the difference when loaded.
When the output is 20V 3.25A, the highest ripple is 72 and 90mVp-p.
When the output is 5V 2A, the lowest ripple is 16 and 18mVp-p.
As we mentioned, in the process of converting AC to DC, energy will be converted into heat.
We’ll put it into a 25°C thermotank throughout the test and let it run for an hour.
And firstly, the maximum temperature on two sides are 76.4°C and 75.8°C under 220V 50Hz.
Then, the maximum temperature on two sides is 87.6°C and 78.5°C under 110V 60Hz.
Well, that’s all performance tests of this UGREEN 3-in-1 65W GaN charger.
We found its performance is pretty stable. And both USB-C ports can support up to 65W.
Since it also supports PPS and Huawei SCP protocols,
it can be compatible with many different devices.
And you can charge three devices at the same time.
So, a single charger is enough for you to travel around.
OK, that’s all for today’s video.
You can click the corners to view other UGREEN products we’ve taken apart.
See you in the next video. Bye.
