Whether you’re at home, at work, or away with friends, you can use the Zune AC Adapter to charge your Zune without hooking it up to a computer. With the AC Adapter, your Zune will be 90% charged after only two hours, and fully charged in about three hours. Note: This is a US charger although it will work with UK 240v with an adapter. ZuneThings will include this US to UK adapter at no cost.
