1. Its size is very small (it can be held with one hand), but through the upgraded chip TPA3116, the output power is increased to 100W (50W * 2). When you see it, you will be surprised at its output power and its size.
2. Support AUX/USB/Bluetooth input. You can enjoy music in different ways. Bluetooth has also been upgraded. It can automatically switch the input mode (unplug the AUX audio cable and automatically switch to the Bluetooth mode). Now it is more stable and faster.
