Dark Energy's Reservoir (funding through March 28) feels like a bid to stake out a high-end niche of the portable charger market with quality materials; enormous energy storage capacity; diminutive size; and a sleek, vaguely mysterious, mildly sci-fi aesthetic.

Purportedly the result of extraordinary research into what users truly want in their portable chargers, Dark Energy is confident that its product is of uniquely precise appeal--a portable friend whose aid can free you from physical electrical tethers for a week. Clad in soft black material, the 8000 mAh capacity device allegedly holds enough juice to charge a normal smartphone an average of five times over (it also works with tablets using a 2A output). Weighing 5.9 ounces, the Reservoir is able to simultaneously charge two devices via USB, and boasts a recharge cycle of 500-plus times. At roughly half an inch, the Reservoir is the thinnest in its category.

The current minimum pledge required to grab your Reservoir is a limited supply "International" tier of $76--meaning it doesn't come with an AC adapter, you use the micro-USB-to-AC connection you've already got--or $79 with one. There also exist a multitude of connector cable mix-and-match options for varying minor hikes in prices.

Confidence level

Funding is complete, and the campaign is closing in on its stretch goal of $150,000. If that's met, all backers will get a waterproof bag for their Reservoir as well. The Reservoir represents Dark Energy's first product, but the young company appears capable. Designs have been finalized, manufacturers have been lined up, and prototype testing complete--all that remains for the team to do is tool some equipment and production may begin.
