preface
The results of the recent Snapdragon 8 starter battle are known to everyone... MOTO coldly came out on top, and also brought the product that everyone evaluated this time - 68W charger.
This charger is sold with edge X30, using Gallium nitride components, the key is that it uses a USB-C interface, with the relationship between Lenovo and USB-IF, this charger is worth looking forward to, not much to say, on the test.
Product introduction
The 68 bright lettering on the front of the MOTO 68W Gallium Nitride charger surfaces the power of this charger, which is more special, and the following is detailed.
The charger is overall matte processed, with a single USB-C output on the top.
From the side, it looks like this charger has good volume control.
MOTO's classic logo.
One circle of the USB-C interface is dented, and the rubber tongue is orange-red.
The prongs are non-foldable, and the pins are plugs.
With a silkscreen inscription on the bottom, the model number MC-688 supports wide voltage inputs.

Product reviews
After introducing the appearance size of the MOTO 68W Gallium Nitride charger, we will take a look at the specific experience of this charger. The charging head network will take everyone to understand this charger from the aspects of protocol test, compatibility test, charging test, standby power consumption test, etc.
Charging protocol testing
In terms of protocols, ChargerLAB's POWER-Z KT002 is used to read the charger's fast charging protocol, and the actual test supports charging protocols such as QC4+, PD3.0 and PPS.
In terms of PDO messages, it supports four sets of fixed voltages of 5V3A, 9V3A, 15V3A and 20V3.4A and 3.3V-11V5A, 3.3V-20V3.4A, which have better device compatibility, and it seems that this charger has guaranteed the performance of charging notebooks.
Charging compatibility testing
The compatibility test link can clearly know the charging situation of the charger for each device, and the charging head network will use dozens of devices with the charger for testing, presenting the reader with real test data.
Charge the iPhone 13 Pro Max with approximately 9.1V 2.93A 26.74W.
Charge the Black Shark 4 Pro with approximately 17.04V 3.45A 58.93W.
Charging the Red Devil 6 Pro, the power is about 17.7V 3.7A 65.5W.
Charge the iPad Pro at approximately 15.19V 2.17A 33.08W.
Charge the MacBook Pro 16 at approximately 20.28V 3.14A 63.8W.
Powered the Switch TV base and successfully triggered TV mode at about 4.55W.
Charge the Mijia hand drill, the power is about 5.31V 2.9A 15.46W.
Organize the data into the table, the charger compatibility is quite good, whether it is a mobile phone or a notebook, as long as the PD protocol compatibility is good, it can be used.
The charging power is sorted from high to low, and the histogram is made to make a histogram to intuitively compare the difference in charging power between different devices.
Full test of charging
Charging the whole test can clearly see the changes in the parameters during the charging process, this time the model used is MacBook Pro 16 2021, to see the data changes in the whole process of charging.
The voltage of the whole charging process is maintained at about 20V, and the power is maintained at about 65W for 1 hour and 15 minutes before charging, and then it enters the trickle charging mode at 1 hour and 33 minutes, and the whole process takes 2 hours and 30 minutes.
The charging data is sorted into a graph, the first half hour of the charger for the notebook charged 30%, one hour charging 60%, the whole process takes about 2 hours and 30 minutes.
Standby power consumption test
If the charger is often plugged into the socket and not used, it will consume power, but it is very small. Many readers want to know whether the charger is wasted if it is always plugged into the socket, and the standby power consumption test session is to answer this question.
After the power meter test, the charger in 220V 50Hz no-load power consumption of 0.051W, converted to a year's loss of electrical energy is about 0.446KW·h, if the market price of electricity is 0.6 yuan / KW·h, the charger's annual electricity cost is about 0.26 yuan.
The no-load power consumption at 110V 60Hz is 0.026W, which translates to a year's loss of electrical energy of about 0.227KW·h, and if the market price is 0.6 yuan/KW·h, the charger's annual electricity cost is about 0.13 yuan.
Conversion efficiency testing
A charger is essentially a conversion device that is lost during the process and dissipated in the form of heat. We usually look at the charger above the parameter output 100W or 65W is the maximum output power that the charger can provide for the device, but the charger draws power from the socket is often larger, the following is the charger in the case of 220V 50Hz and 110V 60Hz AC input respectively carried out conversion efficiency test, the test results are as follows:
At 220V 50Hz, the output power of the charger in each voltage gear is fully tested: the input power of the AC terminal of the power strip and the output power of the USB terminal are measured in four gears, and the conversion efficiency of the charger is calculated from 89.59% to 92.52%.
At 110V 60Hz, the conversion efficiency of the charger varies from 89.88% to 91.62%.
Ripple test
Due to the switching power supply in the charger, the secondary output of the transformer is not direct current, and it needs to be rectified and capacitor filtered, that is, there will be ripple in the charger output. The charging head network uses an oscilloscope to test the ripple value of the charger output, compare with the national standard, and detect the output quality of the charger. The lower the ripple, the higher the output quality of the charger.
This is the ripple test using the charger at 220V 50Hz AC input, the ripple test is divided into no load (Y axis current in the histogram is 0A) and heavy load (the Y axis current in the histogram is non-0A), the highest 86mVp-p charger is at 5V3A output; the lowest 26mVp-p charger is at 15V0A no-load.
At 110V 60Hz, the maximum is 94mVp-p, and the charger is at 15V3A output; the minimum 20mVp-p charger is at 15V0A output.
Ripple test summary
The national standard in the charger ripple requirements are not higher than 200mVp-p, MOTO 68W Gallium Nitride charger in 110V 60Hz, 220V 50Hz input voltage, all output power ripple peak-to-peak are lower than 200mVp-p this standard, good performance.
Temperature testing
As mentioned earlier, the charger will involve the problem of efficiency conversion, and the vast majority of the lost power is dissipated by heat, so the heat of the charger working for a long time is also an important part of the test. The charger was continuously output at 68W power for one hour, the surface temperature of the charger was collected, and the charger was placed in a 25 °C incubator throughout the experiment.
First, let's take a look at the temperature performance of the charger in the mains environment of 220V50Hz.
After one hour, the maximum temperature of the charger front is 60.2 °C.
The maximum temperature on the back of the charger is 64.8°C.
Look at the temperature performance of the charger in the mains environment of 110V60Hz.
After one hour, the maximum temperature of the front of the charger is 70.1 °C.
The maximum temperature on the back of the charger is 68.4°C.
Full load stability test
After long-term use, will the charger be reduced due to overheating? The charging head network also tested the MOTO 68W Gallium nitride charger.
The charger gear is adjusted to 20V3.4A, with 68W power continuous output for one hour, the voltage and current during the test are horizontal and straight, there is no obvious fluctuation, and the use of full load for a long time is also quite stable.
Charging head net summary
MOTO 68W Gallium Nitride charger as an accessory with edge X30, the product appearance is low-key and simple, frosted shell plus fixed plug, bland appearance but contains a clean, it is a pure PD charger, excellent versatility, MOTO edge X30 compatibility with third-party chargers is beyond doubt.
MOTO 68W Gallium Nitride charger mainly supports PD3.0 and PPS two fast charging protocols, with four-stop fixed voltage, the highest output power of 68.2W, measured whether it is a mobile phone or a notebook have good compatibility, and a small size, power density of about 1.01W/cm, is definitely the conscience of the mobile phone official.
