The USB-A ports on pretty much every IFE deployment are a total waste of time - they output 500mA max, and because it's so low many devices won't even draw that. My testing has shown charge speeds of around 300mAh on multiple devices meaning you're looking at around 10 - 12 hours to charge a typical phone.
The new USB-C ports on the neo output 5/9/12/15/20V PD up to a maximum of 27W so will fully charge a modern Android or iPhone at maximum speed which is around 15W - 18W depending on the device. Ironically despite the iPhone not having a USB-C connector, the only way to fast charge an current gen iPhone at maximum speed is to use a PD capable charger and a USB-C to Lightning cable.
