[QUOTE="RadDave, post: 1652814, member: 234411"] Well, as already stated - a powered USB hub will provide the extra wattage needed to run some of your peripherals (assuming those are not also powered) - keep in mind that Apple USB 3 ports provide only about 5 Watts of power (see quote below from [URL="https://support.apple.com/en-us/HT204377"]HERE[/URL]) - this amount of power would be enough to charge an iPad Mini or iPhone but NOT a regular iPad, so a non-powered hub will give you the 'non-charging' message for that reason. Now, even w/ a powered USB hub (and these vary tremendously in their specs, quality, and pricing), some peripherals may not work properly, so for critical tasks such as backups/clones and iDevice updates, I like to directly plug into a Mac USB port - have one dedicated w/ an extension cable that runs to the front of our iMac, so an easy task to plug in a peripheral.
