Pocket-sized power

The great outdoors and tech don’t go hand in hand. Water and electricity don’t mix well, and sharp rocks and rugged landscapes aren’t kind to your devices. These days, however, your smartphone is one of the most important items in your kit list, serving as not only your sole means of communicating with the outside world, but also your map and compass, your video camera for capturing those epic moments, and your only source of entertainment during those long nights in the tent. As long as it’s charged, at least. That’s why we love this epic little power bank from Dark Energy, delivering reliable power in a near-indestructible package. With a super resilient outer shell, it’s fully water resistant, can last for weeks in freezing conditions, and comes with convenient MagSafe technology that allows you to easily connect the charger to the back of your phone for full wireless recharging. And all while being roughly the size of a deck of cards.

  • Holds 3,000 MaH of extra power, equivalent to 8 hours of smartphone use
  • USB-A and USB-C compatible
  • Roughly the same size as a deck of cards
  • With a waterproof rating of IP67, it can be fully submerged in water for up to 30 minutes
  • Includes 3 ft USB-C cable
  • MagSafe compatible, meaning it clips to the back of your phone
  • Comes with Mavrik technology for complete wireless charging of compatible devices

  • Smartphone: 5-8 hours of power

These days, your phone is much more than just a tool for communicating with the outside world. It’s your map and compass, your pocket torch, and your means to finance a quick resupply — all at the same time. In fact, it could be argued that it's the singular item that can make or break your adventure more than any other, especially if you’re out of battery the moment you need it. Which is something that the folks at Dark Energy are acutely aware of. As long-distance backcountry adventurers, they often spend days at a time in their native Wasatch Mountains, hiking dozens of miles over harsh terrain in Utah’s unforgiving climate. And they rely on their phones to keep them on track, safe, and connected to the outside world.


Knowing all too well the pitfalls of lesser power products, Dark Energy has made it its mission to create hyper-rugged charging solutions you can rely on in the wild. And since 2013, they have become a brand trusted, used and abused by everyone from hikers, campers and emergency workers to the US special forces — all due to the outstanding quality of their kit.
