Charg­ing from a USB hub

Mac Format - - APPLE TALK -

MacFor­mat re­ported on a new prod­uct a few months ago but now I can't find the write-up about it. It was a short USB cable with a hub to bring USB ports to the front of the dis­play, avoid­ing hav­ing to hunt for one at the back. Can it charge an iPhone and an iPad? Duke Zim­mer­man The drain from a Retina iPad is much higher than from an iPhone or non-Retina iPad. The best way to charge one is us­ing the mains adap­tor that came with it. You can also charge an iPad from the USB ports on a Mac or a Cin­ema or Thun­der­bolt Dis­play, but there are some re­stric­tions. The Mac or mon­i­tor must be on, not sleep­ing; it only works for one iPad at a time; and only from the ports on the back or on Ap­ple’s wired key­board.

Some hubs, like the the Belkin 4-port model avail­able on Ap­ple’s on­line store, can’t charge iPads. That re­quires a hub that can sup­ply 2A of cur­rent. You could try the Anker nine-port USB 3.0 hub (£44 from Ama­zon), which has one 2.1A charg­ing port for your iPad. It’s a pow­ered hub, so you’ll need to plug it into the wall as well as the back of your mon­i­tor.
