Q: Can this be used with a desktop computer?

This is an outdoor heavy duty extension cord . I'm not sure if this would work with a computer.

Q: can you plug a power extention into the cord to have multiple outlets from it?

Don’t see why not. It’s a three prong cord find the right extension and I’m sure you could. I gave nit tried this however, haven’t needed to. Mine is straight from outside outlet ti fountain with a cover the connecting end and covered by the fountain stand. Been using ut two yrs now with no problems.

Q: The description on Amazon says waterproof but the tag on the product says do not use if wet. This is false advertising. Right?

Thank you for your interest Not waterproof as described on the label refers to the plug part. We also included pictures next to the text. Any cord plug is not waterproof. Our wire part is waterproof, please feel free to use it outdoors. addlon lighting
