preface
On April 20, 2022, Lenovo held the 2022 ThinkFamily Spring New Product Launch, bringing business flagship ThinkPad X1 series notebooks, ThinkPad neo 14 notebooks, and ThinkCentre neo series desktops. At the press conference, Lenovo also launched a new generation of Gallium Nitride USB-C mini power adapter - thinkplus lipstick power supply Nano 65W.
With an astonishing 1.45W/cm power density, this third-generation lipstick power supply delivers lightweight charging to the end. The charging head network also received this 65W gallium nitride charger with extreme volume control, let's see its specific performance.
Previous Generation Review
Lenovo's lipstick series charger has launched a total of four products, of course, the color is not the same, the interface configuration here for everyone to sort out a table.
It can be seen that the original lipstick power supply in the case of not using gallium nitride power components, a shot is the king of the explosion, 0.84W / cm power density to today is also the best. The second generation of lipstick power supply is divided into two versions: single C port and 1C1A dual port, which goes further in terms of volume or interface, bringing consumers more lightweight charging options.
In this generation of lipstick power supply, the volume is only 43.99cm, and the power density is as high as 1.45W/cm, which has far exceeded the industry level. If you don't know how small, here can tell you that Apple's original 20W charger volume is 47.78cm, which has a concept.
If the power of 65W is added to the volume of the 20W charger, will the performance of the charger shrink? So without further ado, examine it from the box.

Standby power consumption test
Nowadays, it is the norm for users to use the charger to charge their devices and no longer unplug them from the outlet. 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 0.144W, converted to a year's loss of electrical energy of about 1.26KW·h, if the market price of electricity is 0.6 yuan / KW·h, the charger's annual electricity cost is about 0.756 yuan.
110V 60Hz no-load power consumption is 0.104W, in translation, a year's loss of electrical energy is about 0.91KW·h, if the market price is 0.6 yuan / KW·h, the charger's annual electricity cost is about 0.546 yuan.
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.
The ripple test is divided into two types: no load (0A current on the Y axis in the histogram) and heavy load (the current on the Y axis in the histogram is not 0A). In the no-load part, the charger has the highest ripple at 72mVp-p when it is in the 5V0A no-load state under the 220V 50Hz AC input, and the lowest ripple at 28mVp-p when it is in the 20V0A no-load state.
In the heavy-duty part, the charger has the highest ripple at 84mVp-p when it is in the 9V2A output state at 220V 50Hz AC input, and the lowest ripple at 56mVp-p when it is in the 12V2A output state.
At 110V 60Hz, the highest ripple is 136mVp-p at 5V2A output and 48mVp-p when in 9V2A output.
