I thought with the high power amp advertised it would charge my Google Nexus 6P as fast as the wall wart that came with the phone. After installing an outlet and testing my phone on it, I regret that it doesn't. It doesn't show a "fast charge" message, just "charging" and definitely doesn't charge that fast based on a 1% battery boost after plugging it in for 3 or 4 minutes. But upon closer inspection, it appears to be due to a limitation of the phone when using a Type-C USB to USB cable. So this is not a reflection on this ship, but something to be aware of.
