here are a lot of battery packs, chargers, and gadgets made to deliver more power to your smart devices and computing equipment. And then there’s this, the HyperJuice 2. I could swear it’s a cell inside the Tesla Model S.
This 100Wh battery packs almost 19x the power of the iPhone 5, and will triple the life of an iPad (4), and even more than that for the 11″ MacBook Air. The entire package is a 1.6 lbs brick that’s 8″x5″ of pure electron flow. Two 10W USB out ports and a DC out module enable this bad boy to pump out to three devices at once. In a strange way, you can actually use the HyperJuice as a no-wall-charger-necessary device charger for your choice of devices: Android, iOS, laptops, and whatever other USB-based gadgets you can think of. Though considering the 10W power output, stick with charging only higher-powered devices, not rechargeable mice and the like.
Let me throw some numbers at you: this lithium-ion battery can quadriple the last-gen MacBook Air’s battery life, add 34 hours to the iPad 3/4, and add 71 hours to the iPad mini. It runs circles around smartphones. The tiny LED display shares all the pertinent info, including the current temperature (in both Fahrenheit and Celsius), the current charge, and whether it’s charging, discharging, or just hanging out.
For $300, the HyperJuice 2 isn’t for everyone, but it certainly will have a home for many. Business travelers will adore the ability to not only charge anywhere, but to do so with multiple devices. Sure, the weight and dense size isn’t great for travel, and lord knows what the TSA will think of it, but for those times when you need electricity and there just isn’t any available, the HyperJuice 2 can be a lifesaver. On multiple occasions I’ve used it for when I forgot to power up my Windows RT tablet, iPad, iPhone, and even a laptop here and there. I just leave the HyperJuice in my car; and the rare times when the included ports aren’t enough, the battery even comes with a 12V car power outlet.
That’s really the beauty of the HyperJuice 2 (and newer, higher-capacity power bricks): extreme battery longevity for when you need it. And that’s exactly how it works. I only use the HyperJuice when I need it; otherwise I refill it when it’s depleted. A simple aluminum finish to match your iDevices is just icing on this most delicious cake. The four hours to fully recharge means I can charge it in the office or at home, whenever it’s discharged. And I’m never stuck with any electronics hissing low power. Ever.
Bottom Line: If you use it right, you’ll never be left with an unpowered smartphone, tablet, or laptop again. Extremely dense, can recharge most devices multiple times over.
