This assembly is great while on a flight and not wanting to unstow the laptop. The iPhone connector is the "Lightning to USB 3 Camera Adapter" ($39 on Amazon).
AnentFunny. I did essentially the same earlier this year, but with an android phone and the Centrance DACport slim. On all the long flights I took, though, there were USB chargers at every seat (even in coach) so I ended up not using the portable charger much .
zep483I used an OTG adapter to a normal 6" USB cable. There are several OTG adapters on the market that have a power port. This power is not meant for the host USB device (aka the phone) but for the USB devices on the bus.
kungfoolouIs the centrance mini USB or micro? I got the recent dacport he drop as well, but waiting on it to come in. I have a note 8, so I'll have to get a type c to whaterver... hopefully with two outs... or for power one for the centrance.
zep483The centrance is micro USB. To connect a USB-C phone to these devices, I used a micro-to-C adapter, make sure it is OTG-enabled. Not all micro-to-C adapters are OTG-enabled. And used a micro-USB OTG adapter with a power port. I did not find any USB-C OTG adapters with power other than hubs, but I haven't looked in a while as I bought a DAP recently. The micro-USB OTG adapters can be cheap and unreliable. Buy a few and test them out.
