If you go into your shopping cart there is a couple of options you can do: (it's right under the quantity button)
1) Remove (this will remove the item(s) completely)
2) Save for Later (this will take the item(s) out of your shopping cart for purchase, but it saves the item(s) at the bottom of the shopping cart page so you can add it back into your cart at a later time without having to search for it again - Very Handy!)
Hi William, I assume you are asking about the power source, it does plug into a standard outlet to operate. If I have misunderstood your question, please don't hesitate to reach out to me again. You can find me by using my link syw.co/sarahramirez .
