Lost or broken your Casio keyboard power cord? This MaxLLTo 9V adapter is the perfect replacement! It's designed specifically for a bunch of Casio CTK models like the CTK-500, 510, 511, 515, 518, 519, 520, 520L, and 530. The output is 9V DC at 2000mA (that's 2 amps), with a center-negative tip – just like the original. What's really cool is the super long 6-foot cable – way longer than most standard adapters, so you can plug it in further away without stretching. It works with any wall outlet from 100V to 240V, making it great for travel too. Built-in smart IC protects against overcharging, short circuits, and overheating. Comes with a US plug, CE certification, and a solid 30-day money-back guarantee plus a 24-month exchange policy. A reliable, affordable way to get your keyboard powered up and playing again!
