How many watts (or amps) do each USB port supply? How many total can all of them provide at once?
Wow, their own website also has little info!
Saw a bit of info on another site:
“Four 5V, 3.1A USB-A ports line the side, allowing you to quickly charge phones, tablets, and other devices. Built-in surge protection with a 1250W power rating bring added peace of mind.”
