I just got a new smartphone. Being hyper-aware of its energy-sucking tendencies, I immediately enabled every power-saving feature available. Screen at minimal brightness, GPS turned off unless necessary. Even though I mostly use it for checking social media and texting, I find myself charging it at least every other day

A new product recently funded on Kickstarter could make daily charging a thing of the past. The Dark Energy Reservoir is a sleek portable that claims to keep your phone powered for nearly a week.

Now, portable chargers, backup batteries and even kinetic chargers are nothing new. We’ve featured dozens on this very site. What makes the Dark Energy Reservoir different is a slim, ergonomic design that packs an impressive wallop of power.

“Like most people I found that at completely inopportune times my phone was dying, my camera would die on vacation, and I was nowhere near an outlet, or I had to go somewhere so I couldn’t charge it,” co-founder Garrett Aida said, in the company’s Kickstarter video.

Able to live undetected in a purse, backpack, or briefcase until needed, the Dark Energy Reservoir is the perfect answer to this conundrum. The device easily charges in 4-6 hours via AC adapter, and can be recharged with any MicroUSB cord or even solar chargers.

When attached, the Dark Energy Reservoir delivers a high-speed recharge any USB device, and can even recharge two USB devices simultaneously (not tablets, though). The gadget retains full capacity for 1 year if unused and has a recharge cycle of 500+times.

But let’s get to the important stuff: It can recharge the average smartphone four to six times, which could translate to an entire week’s worth of power. For my current once every other day cycle, 5 charges would take me way past a week. Which is pretty awesome.

The project recently crushed its Kickstarter goal of $100,000, and will soon be available to the world. Pre-order now at MyDarkEnergy.com.
