I have a Mophie Charge Stream charger that I would like to use with my iPhone 8. It came with a USB cable, and a power adapter.
It works fine if I plug the USB cable into the supplied power adapter, but it doesn't work if I plug it into any other USB port. Am I right in assuming that these things require a USB port that delivers more current than a typical USB port?
Unfortunately I have no spare power sockets at my desk at work, hence why I was hoping to use one of my spare USB ports.
