How Much Water Will Wreck Your Gadgets?

If you’re like me, you take your gadgets with you everywhere you go—inside and outside, from the beach to the bathroom. (Hey, I like singing in the shower.) The problem is that dust and especially water can be kryptonite to electronics. So if you want gear that can handle a spill, some sweat, or an unexpected rain shower, look for products that have some level of water resistance.

How do you know whether a given item can endure your particular lifestyle? Well, there’s a helpful standard called the IP or IPX rating that evaluates products according to how resistant they are to moisture, sweat, and dust. Note that a product lacking an IP rating may still be resistant to water or dust; however, the IP rating offers assurance that a manufacturer’s claims are based on actual testing. To find out more about IP ratings and what they mean when you’re shopping, watch the video above.

It’s important to remember that no matter how high the rating, there are always limits to a product’s water resistance. You should always let your gadgets dry thoroughly before charging them, and in between uses. Make sure the port doors are fully closed before you use your device. And keep in mind that IP ratings refer only to resistance to clear, fresh water. Sweat has a low enough saline component that it’s usually fine, but ocean saltwater, soda, shampoo or conditioner, and other liquids could still cause problems for your device. So feel free to soak in a tub or rinse in the shower with your waterproof headphones, but please take them out when you lather, rinse, and repeat.
