Sanho’s HyperJuice wall charger that debuted Monday isn’t much bigger than a credit card but still has room for a pair of USB-C ports that can put out 100W, dual USB-A ports that max out at 18W, and swappable power prongs.
It uses Gallium Nitride (GaN), a new semiconductor material that’s more efficient than traditional silicon used in current chargers. It lets Sanho create this ultra-portable wall charger.
