Simple to Use, No Computer Required Kindle DX is completely wireless and ready to use right out of the box--no setup, no cables, no computer required. Long Battery Life - Read for Days Without Recharging With Kindle DX's long battery life, you can read on a single charge for up to 4 days with wireless on.

In low coverage areas or in 1xRTT only coverage, wireless usage will consume battery power more quickly.
