Hi, guys. Welcome back to ChargerLAB.
Today, we gonna bring you a very special charger.
It’s equipped with a Lightning port.
So, a single USB-C to Lightning cable can charge iPhone and Android phones simultaneously.
This is the Zhiyou 30W charger.
Since it’s still in development, the shell adopts simple white plastic and is carved with a leaf.
It adopts foldable prongs. And let’s take a look at the specs info.
Model is VUA03003-2112
It can support wide-range input voltage.
USB-C, USB-A, and Lightning ports can support up to 30W.
And it’ll drop to 15W when charging two devices.
The brand is Vobasn. And manufacturer is Zhiyou.
We find it has three different ports.
They’re USB-A, USB-C, and Lightning output ports from top to bottom.
This is also the first time we’ve seen a Lightning port on a charger.
The size of the charger is 49*44*27mm (1.93*1.73*1.06 inches).
So, the power density is about 0.5W/cm³.
Weight is about 58g (2.05 oz).
Compared with Apple 30W single-port charger, this three-port charger is still smaller.
Use ChargerLAB POWER-Z KT002 to test the USB-C port.
It supports Apple2.4A, QC2.0/3.0, QC4+, AFC, FCP, PD3.0, PPS, and other protocols.
It also supports five fixed PDOs of 5V3A, 9V3A, 12V2.5A, 15V2A, 20V1.5A.
And then, the protocol of Lightning port is exactly the same as the USB-C port.
Finally, the USB-A port can support Apple2.4A, QC2.0, QC3.0, AFC, FCP protocols.
Next, let’s test it out with a few devices.
Here are the compatibility test results of USB-C.
Since it’s still in development,
some of the devices can be up to 37W,
which exceeds the 30W limitation.
And most devices can support fast charging.
Then, here is the results of USB-A port.
It’s slower than USB-C port but over 10W.
Next is our protagonist, the Lightning port.
We can use two USB-C to Lightning cables and
our KM001Pro to charge iPhone.
And it’s much easier for USB-C devices.
Just reverse the direction of the USB-C and Lightning ports.
And here is the results of Lightning port.
It can charge all mainstream devices in the market.
And its compatibility is pretty good.
Next, let’s try to charge multiple devices simultaneously.
It should be noted that the USB-C and Lightning port
cannot be used at the same time due to the design.
So, we can only charge two devices at a time.
Use Lightning and USB-A to charge two devices at the same time.
The total output is between 10W-15W.
And then, let’s switch to USB-C and USB-A.
The total output is also around 10-15W.
So, we’re guessing that all three ports share the same circuit.
Except for compatibility test, we also use it to fully charge the MacBook Air with M1 chip.
The Charging Curve is in here, which can be
roughly divided into three stages.
The peak power is 28W.
It can reach 26% in half an hour and 52% in an hour.
And it’ll take 2h 37m to be fully charged.
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 0.093W,
which is about 0.81KW·h in one year.
And the no-load power consumption at 110V 60Hz is 0.081W,
which is about 0.7KW·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 83.71% to 88.81% at 220V 50Hz.
The conversion efficiency varies from 84.07% to 87.15% 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 9V 3A, the highest ripple is 106mVp-p.
When the output is 5V 0A (no-load), the lowest ripple is 52mVp-p.
Then, let’s switch the input to 110V 60Hz AC.
When the output is 20V 1.5A, the highest ripple is 124mVp-p.
When the output is 9V 0A (no-load), the lowest ripple is 12mVp-p.
We’ll put it into a 25°C thermotank throughout the test and let it run for an hour at 20V 1.5A.
And firstly, the maximum temperature on two sides are 78.8°C and 73.3°C under 220V 50Hz.
Then, the maximum temperature on two sides is 71.5°C and 85.2°C under 110V 60Hz.
We also monitored the charging curve during temperature testing.
The voltage curve is horizontal and straight.
But the current curve has some tiny fluctuations.
Because this is a prototype. So, a lot of improvements will be added in the future.
Now, a single USB-C to Lightning cable and this charger
are enough to charge your iPhone and iPad simultaneously.
But we still hope that the iPhone will change to USB-C port someday.
OK, that’s all for today’s video.
