Hi, guys. Welcome back to today’s video.
Recently, we got a 30W charger from Baseus.
Instead of taking it apart, we’ll test its performance, including standby power,
conversion efficiency, ripple, and more.
So, let’s go ahead and take a look.
Firstly, The packaging is as simple as ever, with the “Super Si” logo in the lower right corner.
It contains the charger, manual, and sticker.
The shell is white plastic.
And an LED charging indicator is at the corner.
Both USB-A and USB-C are Orange.
It adopts foldable prongs.
The “30W Super Si” logo is printed here.
After connecting it to power, the indicator will light up.
Here is Intertek’s ETL certification.
Let’s take a look at the bottom information.
The charger model is CCCJG30CS, which supports wide-range input voltage.
Only USB-C single output can reach 30W.
The USB-C can support 18W,
and USB-A can support 12W when charging two devices simultaneously.
The size of the charger is about 48*35*30mm (1.89*1.38*1.18 inches).
So, the power density is about 0.58W/cm³.
The weight is about 64g (2.26 oz).
It’s about half the size of Apple 30W charger. But it’s equipped with dual USB ports.
Use ChargerLAB POWER-Z KT002 to test the USB-C’s protocol.
It can support Apple2.4A, QC2.0, QC3.0, QC4+, AFC, FCP, SCP, PE, PD3.0, PPS, etc.
It also supports five fixed PDOs of 5V3A, 9V3A, 12V2.5A, 15V2A, 20V1.5A,
and two PPS of 3.3V-11V3A, 3.3V-16V2A.
So, its compatibility should be pretty good.
Next, let’s test it out with a few devices.
It’s compatible with iPhone, iPad, and MacBook.
As for Android phones, the power of Huawei is over 10W.
Samsung can reach 20W.
Here are the compatibility test results of the USB-C port. We’ve made a chart for you.
Then, let’s test with USB-A port. Most smartphone is around 10-20W.
Some of them can exceed 20W.
We also made a chart for you.
You can also download it on our official website.
Use it to charge the Samsung S20 Ultra and Redmi K50.
The output power is about 13.5W and 13.3W, respectively.
Total power is about 27W.
We use it to charge the iPhone 13 Pro Max fully. The Charging Curve is in here.
The voltage rises from 5V to 9V in about 3 minutes and starts fast charging.
It drops from 9V to 5V in about 59 minutes and ends in 1 hour and 44 minutes.
Compared with Apple 30W. Those two curves almost overlap.
But the Baseus 30W charger is a little bit faster at the final stage.
I’m sure most people won’t remove the charger after charging your 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 at 220V 50Hz is 0.163W.
And it’s 0.161W at 110V 60Hz.
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 83.82% to 90.03% at 220V 50Hz.
The conversion efficiency varies from 83.12% to 89.11% 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, the input is 220V 50Hz AC.
When the output is 15V2A, the highest ripple is 36mVp-p.
When the output is 5V0A (no-load), the lowest ripple is 14mVp-p.
Then, let’s switch the input to 110V 60Hz AC.
When the output is 15V 2A, the highest ripple is 38mVp-p.
When the output is 9V 0A (no-load), the lowest ripple is 14mVp-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 is 66.9°C and 61.8°C under 220V 50Hz.
Then, the maximum temperature on two sides is 67.7°C and 63.3°C under 110V 60Hz.
We also monitored the charging curve during temperature testing.
The curves are horizontal and straight, without obvious fluctuations.
Well, as a well-known brand, this Baseus charger is very sophisticated.
It can support mainstream charging protocols,
and it’s equipped with a USB-C and a USB-A port.
So, only one charger is pretty enough for you to fast charge your iPhone,
iPad, and Android device when you’re traveling.
If you are interested in this charger,
there is a surprise waiting for you in the description.
And that’s all for today’s video, see you next time.
