Green Union has always given people the impression that "cheap enough", known as a low-price killer in the accessories industry, the products are mostly oriented to the low-end market, focusing on high cost performance, the price is generally only two-thirds of similar products of first-line brands, although the materials are slightly inferior, and the design is not very bright, but the actual performance gap is not large, and the charging speed and charging stability are at the average level.
 
The advantage of Greenlink is also that its product attributes are quite rich, basically covering the needs of all groups of people, taking the charger as an example, covering PD, QC fast charging, single/multi-port fast charging and other products, whether it is Android users or Apple users, you can find your own products in related categories.

These three have their own characteristics, CD122 is a single-port charger, the maximum power of 18W, so it is suitable for users with a single-wielding Android device, CD132 and CD161 are dual USB port fast charging, CD132 total power 30W, the two interfaces support QC 18W and Apple 2.4A 12W protocol respectively, CD161 maximum power 36W, both USB ports support QC3.0 18W fast charging, if there is a need for multiple devices to charge at the same time, and it is an Android and Apple dual-wielding user, It is more suitable for CD132, and if you only have Android devices, CD161 is more suitable.
