Evaluation summary
In terms of appearance, this charger has a very unique design, which is about the same size as Apple’s 20W PD charger. Performance supports 3A charging, which is basically suitable for all mobile phones. The size of the product is also relatively small, not heavy, and easy to carry. For small partners who usually travel a lot, using this charger as a spare accessory is a very good choice.
