If you’re using technology near a pool or on the beach, you know there’s a risk of it getting splashed with water. Smartphones have gotten more water-resistant — often at the expense of features like a headphone jack — but accessories have been a little late to the game. Waterproof chargers have finally started appearing recently, and they offer the ability to charge your gadgets by water without getting splashed.
These rugged chargers have a thick, rugged body, which means they’re bulkier and heavier than the ones you can slip in your pocket to quickly charge your phone on the go. Still, the extra size and heft is worth it for the added protection.

The best waterproof chargers are an essential part of any camping or hiking kit, with a weather-resistant construction that holds up to the elements. They’re great if you need to power up by the pool too, and we like that they won’t stop charging even if you’re caught in the rain and the charger gets wet.
It still pays to be cautious — you shouldn’t drop these waterproof chargers in the pool, or intentionally leave them out in the rain — but it’s nice to have some peace of mind in case an accident happens.
What You Need to Know Before Buying a Waterproof Charger
There are many factors to think about when choosing the right waterproof charger for you; below are the most important ones, which we considered while we were researching this list.
Battery Capacity: A waterproof charger’s capacity — measured in milliamps (mAh) — determines how much power it can hold. The greater the capacity, the more it can charge your devices. All of the waterproof chargers in our guide have a capacity of 20,000mAh or higher. For reference, the smaller, pocket and purse-friendly battery packs you may be familiar with hold about 10,000mAh of power — or even less.
Ports: We chose waterproof chargers that have standard USB ports on them, which allow you to charge the greatest number of devices without any adapters. Some also have USB-C ports, which allow you to charge modern smartphones and tablets more quickly.
Water Resistance: An electronic’s water and dust-resistance is measured on the IP (Ingress Protection) scale. The waterproof chargers we chose have at least an IPX5 rating which means it’s designed to survive exposure to jets of water. Again, don’t go dunking your waterproof charger in water, but be assured it’ll hold up in a rainstorm.
