This outdoor surge protector is designed for use in wet and outdoor environments, thanks to its IPX6 waterproof rating. It can handle rain and splashes safely, but it shouldn’t be submerged in water. With three outlets spaced widely apart, it can easily accommodate larger plugs without crowding, which is helpful if you have bulky adapters.

The 10-foot cord gives you some flexibility to place it where you need it, though it’s not the longest cord available.
