Introduction
---------------------------------------------------------------
The Switch dock and its original charger are pretty hard to carry for many people who want to play switch in TV mode anywhere.
And today, ChargerLAB got a charging dock from HAGiBiS, equipped with an HDMI port, which can replace the huge dock and charger.
It adopts the GaN components, so its size is much smaller.
