Here they make you pull any tablet or laptop out of your carry on for individual X-ray, cellphones included.
Once recently I was pulled aside to check my carry on backpack that had 2 chargers, a bluetooth headset, headphones and a few other cables, bits and bobs in it. Must have looked dodgy on the X-ray screen but it's the same kit I've traveled with before and always previously gone straight through.
Same kit on the return journey went straight though.
For the OP, just carry it on and put it in a separate tray for close inspection and you'll be fine, leads in check in or course.
