Dark Energy Reservoir is a powerful external USB battery pack in a sleek design – $129

Our mobile devices make our life so much easier and more fun, but without power they’re totally worthless. When at home or at work most of us are able to keep our phones and tablets charged up, but power isn’t always as easy to find while on the go. You can always bring a wall charger and hope to find an outlet somewhere but why not bring your own little box of power along instead?

The Dark Energy Reservoir isn’t the first device of it’s kind but it’s one of the best portable battery packs I have come across so far, and also one that I use myself on a daily basis. It launched as a Kickstarter project in early 2013 but it is now available to anyone to purchase. The Reservoir has a very nice and slim design, excellent build quality and it can recharge an iPhone 5S almost five times in a row.

I keep one lightning cable (to charge my iPhone and iPad mini), one mini-USB cable (to charge the battery pack itself) and a Dark Energy Reservoir in my bag at all times. This little device has been a blessing to me while using my phone as a personal WiFi hotspot at coffee shops, on long flights and on hikes far away from power outlets.
