We’ve been using this Belkin 7-port powered hub to sync and charge our iPads. We bought it from Insight for the grand total of £7.47 ex VAT. Click here to see the hub on insight. It can take up to 7 devices at once and even thought the iPad says ‘not charging’, it is. The hub has to be plugged in to power and also a computer to work. It’s done the job for us fine.
