Review: great little device; lets me charge my phone and use a DAC at the same time - USB-C PD seems to work well, I've driven about 60 watts though it and it stays cool while still allowing the side port to work. It allows at least up to 20 volts via PD but seems to disable any PPS modes, but I guess that's reasonable given its size and the need to provide 5v to the side port. I've pulled about 1.5 watts through the side port, far more than it'd ever need for a DAC (i.e. it'll easily charge a Qudelix 5K) or most lower power devices. Power draw of the adapter itself is minimal, ~0.01 watts so it's not going to drain your phone's battery if it's left plugged in (I've got USB-C cables that somehow pull 0.1 watts). ChargerLAB KM003C used for testing. I also got the type-A version, but it seems to have a slightly higher idle power draw, so stick with this one and a separate adaptor if you want type-a support.
Review: Vital for external drives on phones and tablets - Great gadget. Allows use of external hard drives on phones and tablets with USB C by having an extra port to attach to power. Without this, the drives don't fully work and will report a format error on your device due to insufficient power being available to the drive. Just plug this into your phone or tablet, usb c power into the long side (from mains charger or powerbank) and usb c from your drive into the short side port. This allows quick file transfers in both directions.
