Have you ever seen a lipstick power supply that is small enough to use a coin as a reference?

Thanks to Lenovo, for giving the thinkplus lipstick power supply GaN Nano 65 colorful version the third-generation mini adapter a trial opportunity, I must use it well, record the use experience truthfully, and share it with everyone. This is what it looks like before it is opened: the product model is GN65, GN stands for gallium nitride, and 65 stands for power. What caught my attention the most on the outer packaging was the pile of barcodes on the box. There were as many as 7 barcodes on the box, which instantly gave me the visual sense of a big home appliance. Most of these barcodes are used for tracking and management in the process of production, warehousing, sales and after-sales, and the purpose is to ensure product quality and service quality. Behind it is a series of huge support systems and support systems, which are really not affordable for small companies. Therefore, you don't have to understand what they mean, just understand them as "guaranteed by big factories". The following is what it looks like after opening: The following is what it looks like after taking it out: The volume is really small, smaller than most mobile phone power supplies, and it is small enough to use a coin as a reference. What is valuable is that although the volume is small, the power is very large. As mentioned earlier, the maximum is 65W. The power is so abundant that it can even be used as a notebook power supply (requires a Type-C interface), which is why the charging cable is 1.8 meters long. Think of the black brick-like adapters of traditional notebooks. Compared with the GN65, they have become synonymous with stupid, black and rough. Apple's Mac Pro adapter is white, smaller in size and thinner than ordinary notebook adapters, but the weight is really not light, and it is also a fool in front of the GN65. The key is that the heat generation of the Mac Pro adapter is really gratifying. The upper half of the sun in winter can offset half of the air conditioner in summer. It is said that the calorific value of the gallium nitride power supply is much smaller, about 10 degrees lower than the temperature of the ordinary power supply, you can try it later. Roughly estimated, the power-to-volume ratio of GaN adapters is only 3 to 4 times that of general adapters. (Compared with the GN65, the ordinary notebook power supply has become "stupid, black and thick") However, I want the GN65 to mainly charge the mobile phone. The first test was fast charging, and the Honor mobile phone was selected. The result was 20% charging in 20 minutes, and the original charging was 25% in 20 minutes. The difference is 5%, and the speed is still acceptable. Interestingly, the original maximum output current is 4.5A, GN65's 3A, and the actual charging speed gap is much smaller than the maximum output current gap. It appears that GaN adapters may be more efficient. In terms of calorific value that I am more concerned about, there is also a gap between the two sides, but the sensory difference is not big. The temperature of the GN65 is slightly lower. There is another interesting difference. The charging icon in the status bar of the mobile phone is slightly different. The original one is two connected lightning bolts. The charging icon of the GN65 is a large lightning bolt and a small lightning bolt. The size of the small lightning bolt is about the size of a large lightning bolt. half of . For the ordinary charging of the second test, the choices are Huawei and Honor, and the retired mobile phone at home will come in handy. Everything went well, except that the heat generation was slightly smaller, the charging effect of the GN65 was not much different from the original adapter. The third test is the neck massager. The Type-C interface is really popular, and this kind of gadget is used. The process went smoothly, nothing to say. (As long as my home has a Type-C charging port, it seems that GN65 can be used.) To summarize. Lenovo thinkplus lipstick power supply GaN Nano 65 colorful version of the third-generation mini adapter has the advantages of small size, high power, and multi-purpose. The latter is its greatest value: think about it, if a company has a Mac pro, a Lenovo laptop, an Android tablet, and a mobile phone in the pocket, then at least 4 adapters are needed, taking up space. Not to mention, the messy wires, but it's a headache to look at. With a GN65, these adapters can be packaged and collected.
