Several weeks ago, we posted a charging review video of the 35W universal travel adapter from MOMAX.
You can click the upper right corner to check that.
Today, we got a more powerful travel adapter from MOMAX, which can support 65W PD charging.
It comes in three different colors, namely white, black and purple.
Flip to the back.
All specs info are on the back.
We’ll talk about it later.
Open the front cover.
Like the 35W version, it’s printed with detailed instructions for users to start quickly.
The 35W version is black.
But this 65W version adopts white and grey plastic.
The 65W USB-C port is also on the side.
You can also use those three toggle switches to switch between AUS, US, EU, and UK plug.
Then, let’s take a closer look at the specs info printed on the back.
Model is UA8.
The AC part can support up to 2500W.
And the DC part can support input of 100-250V, 50-60Hz 0.8A.
The output power for USB-C1 can be up to 65W.
And the other four ports only reach 15W.
When charging two devices at the same time, the power of USB-C1 will drop to 45W.
Finally, the output power won’t exceed 65W.
It also comes with two 10A fuses inside for emergencies.
Just like the 35W version.
The size of this adapter is about 50 x 53.5 x 77mm (1.97 x 2.11 x 3.03 inches).
And the weight is about 182g (6.42 oz).
It’s pretty similar to a typical high-power charger.
You can take it with you wherever you go.
The ChargerLAB POWER-Z KM003C shows the USB-C1 supports FCP, SCP, AFC, MTK, SFCP, QC5, PD3.0, and PPS protocols.
It also supports five fixed PDOs of 5V 2.4A, 5V/9V/15V3A, 20V 3.25A, and two sets of PPS.
The other four USB ports only support DCP protocol and up to 5V3A.
Take the 65W USB-C port as an example to test its charging compatibility.
It can reach 50-60W when charging some high-power PD laptops.
Since it also supports QC5 and PPS protocol,
some Android phones can take advantage of this, reaching over 50W.
The rest of the devices are around 20W.
When charging five devices at the same time, only the USB-C1 can maintain at about 45W.
The total power of the other four devices only reaches 15W.
Next, we’ll use it to fully charge the MacBook Air M2.
Here is the charging curve made by the PC software of KM003C.
The voltage is always around 20V.
The charging curve can be divided into five parts.
The peak power is about 61W at 21 mins.
Then, it’ll gradually drop to 54W, 39W, and 25W in turn.
The final part begins at one hour and 9 mins, and the power slowly drops to almost zero.
It takes two hours and 20 mins to be fully charged.
We also plot it into another curve to see how fast it can be.
It can charge the MacBook Air M2 to 50% in 29 mins and 80% in 59 minutes.
And it reaches 100% in 2 hours and 20mins.
As for the standby power part, the power consumption at 220V 50Hz is 0.082W, and 0.053W at 110V 60Hz,
which is about 0.72 and 0.46KW·h in one year, respectively.
So, you do not need to worry about the waste of electricity.
In the conversion efficiency test,
the conversion efficiency varies from 91.19% to 80.95% at 220V 50Hz.
The conversion efficiency varies from 89.29% to 81.17% at 110V 60Hz.
It’s worse than the 35W adapter,
but still average in all of our conversion efficiency tests.
Next, let’s test its ripple.
The lower ripple means better quality.
Firstly, let’s check out its ripple without load.
The ripple at 220V 50Hz is higher than 110V 60Hz in all five outputs.
When the output is 5V 0A, the highest ripple is 58.4 mVp-p.
When the output is 12V 0A, the lowest ripple is 20.8 mVp-p.
Then, move to the ripple test when loaded.
When the output is 20V 3.25A, the highest ripple is 115 mVp-p and 108 mVp-p, respectively.
When the output is 5V 3A, the lowest ripple is 87.2 mVp-p and 53.6 mVp-p, respectively.
Although the maximum ripple is better than the 35W travel adapter, it’s not the best.
Next, we gonna put the travel adapter into a 25°C (77℉) thermotank and let it output 65W throughout the test.
After an hour, we got the maximum temperature.
Under 220V 50Hz, the front is 69.4°C (156.92℉).
And the back is 63.6°C (146.48℉).
Moving on to the 110V 60Hz.
The maximum temperature on the front and back is 69.3°C (156.74℉)
and 63.9°C (147.02℉), respectively.
The maximum temperatures are pretty stable under different voltages.
The IEC 62368 specifies that the maximum temperature of plastic cannot exceed 77°C (170.6 ℉).
So, it complies with the standard but is very close to it.
Well, that’s all tests for this 65W universal travel adapter from MOMAX.
Compared with the 35W version, the 65W output power can even fast charge your laptop.
PD and PPS protocols can make it compatible with various devices.
In this way, you can even travel around the world with only one adapter.
Like the 35W version, it also performs well in standby power test.
But the maximum temperature and ripple are not controlled very well.
OK. That’s all for today’s video.
