Dongle DAC with a magnetic battery pack

Spoiler: Dongle DAC with a magnetic battery pack

FiiO's Dongle DAC KA3 has been well received since its launch. However, there are indeed some problems with this kind of dongle DAC, which are mainly reflected in:
1. The Dongle DAC need to be powered by your phone. To achieve good sound quality, the power consumption wouldn't be small, which will lead to obvious decline of battery life after listening to songs.
2. Some phones have restrictions on power supply to external devices or music apps might be killed in the background when supplying power to external devices. This also leads to compatibility issues and the user experience is not good enough.
Therefore, we designed an additional battery pack, which uses a magnetic interface to dock with the Dongle DAC. In this way, you can choose to use this external battery to power the dongle to improve performance, reduce power consumption and improve reliability and stability.
If you think that the battery pack will bring extra weight and affect portability, you can easily remove the battery pack and still use it as a very small and portable dongle.

the magnetic battery pack is brilliant. that's what today's dongles lack: modularity. who knows what else you can think of in terms of modularity.
