CR-10 Heater Cartridge Stock Replacement for CR-10-S4, CR-10S, CR-10-S5

This is a stock Creality Heater Cartridge.  

12V 30 Watts. 

Also available in a 12V 40 Watt version.

Includes 30 inch long lead.

The 30W version is more than adequate for most plastics and hotends.  You can use a 40W hotend in place of stock one, but it wont be of much benefit, unless you are currently having trouble maintaining temps over 280C.  The printer will cycle hotend heater on and off as needed to regulate nozzle temperature.  Using a 40W heater without needing one, just puts added strain through the control board, which may not be necessary, depending on your application.
