Accessories

Apple offers several iPad accessories,^[77] most of which are adapters for the proprietary 30-pin dock connector, the iPad's only port besides the headphone jack.^[6] A dock holds the iPad upright at an angle, and has a dock connector and audio line out port. Each generation of iPad requires a corresponding dock. A dock that included a physical keyboard was only supported for the original iPad,^[78] but all generations are compatible with Bluetooth keyboards that also work with Macs and PCs. The iPad can be charged by a standalone power adapter ("wall charger") also used for iPods and iPhones, and a 10 W charger is included with the iPad.
Apple sells a camera connection kit that consists of two separate adapters for the dock connector, one to USB Type A, the other an SD card reader. Adapter can be used to transfer photos and videos and to plug USB audio card or MIDI keyboard.^[79] A third party sells an adapter that includes USB, SD, and microSD on a single unit.^[80] An adapter to VGA connectors allows the iPad to work with external monitors and projectors. Another adapter mirrors the screen onto HDMI compatible devices in 1080p and works with all apps and rotations. Unlike other adapters, it allows the iPad to charge through another dock connector.^[81] While the HDMI adapter was released with and advertised for the iPad 2, it also works with the first-generation iPad, the iPhone 4, and the fourth generation iPod Touch.^[82]

A Smart Cover can be used as a stand for the iPad 2 while the display is in use.

Smart Covers are screen protectors that magnetically attach and align to the face of the iPad 2. The cover has three folds which allow it to convert into a stand, which is also held together by magnets.^[83] While original iPad owners could purchase a black case that included a similarly folding cover, the Smart Cover is meant to be more minimal, easily detachable, and protects only the screen. Smart Covers have a microfiber bottom that cleans the front of the iPad, which wakes up when the cover is removed. There are five different colors of both polyurethane and leather, with leather being more expensive. Smart Covers are not compatible with the original iPad.^[84] In June 2012, Apple started selling the Smart Case - a case with the combined function of a smart cover and a back protection case which is compatible with the second and third generation iPads.
