Many of Yamaha's portable keyboards and other electronic instruments do not ship with a power supply in the box, so the Yamaha Survival Kit is an essential accessory. Note: most Yamaha portable keyboards operate on batteries, but the batteries are sold separately, so the Survival Kit is critical.

This Survival Kit contains a power adapter that is perfect for your keyboard, a footswitch and a set of stereo headphones. You also receive a two-year extended warranty and more than $200 in rebate offers on great Yamaha instruments and accessories, along with learning software, additional songs and more.
