Ampy Turns a 30 Minute Jog Session Into 3 Hours Of Battery Life

ampy

Harnessing kinetic energy in order to power consumer electronics isn’t a novel idea. Some of you may remember the nPower PEG from 2009’s CES, a gadget that promised to recharge your electronics from power gathered through your walking. Well, Ampy is pretty much the same thing, only in a smaller and more refined package. It packs an internal 1,000 mAh battery which is itself charged by a “proprietary linear inductor” that turns kinetic energy into electricity. Other devices use a magnet that slides back and forth along a coil, generating electricity in the process, though the proprietary nature of Ampy’s mechanism doesn’t allow us to confirm it’s the same thing. Regardless of how it works, its creators affirm that a 30 minute jogging session (or 1 hour cycling, or 10,000 walking steps) will top up its battery, which you can then use to fill a typical smartphone back up to about 75% charge. For any outdoorsy types, this could be interesting, especially at it’s early-adopter price of $75, on their Kickstarter.

This Battery Pack By Cobra Electronics Can Jump Start Your Car

cobra_jumpack

We’re used to seeing battery packs that can power a laptop or a tablet or any mobile device. Well, the CPP 7500 JumPack Portable Power Pack by Cobra Electronics does that. But it also packs enough juice to actually jump start your car as well. Churning out a massive 200Amp starting current, it can deliver up to 400Amp at peak, which is enough to get most dead car batteries up and running in no time. And it can do that multiple times on a single charge. Of course you don’t want to blast a mobile device with 200 Amps, so there’s also a 2.1Amp USB output for more moderate charging tasks. It measures 1 x 2.9 x 5 inches and weighs 10.6 ounces, which makes it easy to carry. At $110, it’s a steal.

Deal Of The Day: 150 Batteries For $56?!

redesign_duracel_mf

Everyone needs batteries, right? And although you could be getting rechargeables, no one really likes them because you have to have a charger for one, and also let’s face it, you’re always forgetting to charge them and when you need them, they’re empty. So how about you you get a truckload of batteries for a ridiculously low price? We’re talking about 100AA and 50AAA Duracell batteries. The real deal. For $56! That’s pennies per battery, but act fast because this deal is ending tomorrow.

Smartphone Batteries That Charge In 30 Seconds May Be Just Around The Corner

storedot-590x330

StoreDot is an Israeli startup that’s been working on making our batteries better. They’re created a prototype that can go from 20% to 100% in about 30 seconds, and then discharge at the same rate as a regular battery. This is accomplished by using organic “nanodots”, or 2 nanometer wide “bio-organic peptide molecules” that fundamentally alter the way the batteries work. The company has even received $6 million in funding from an undisclosed Asian smartphone manufacturer to further work on the technology, because as exciting as this is, it isn’t ready for prime-time. For one, the current prototype is huge. Secondly, capacity is still an issue, since even at this size the battery doesn’t even equal that of a Galaxy S4. But these are hurdles that could potentially be overcome, and StoreDot is hoping to have something commercially viable by 2016.

Stay tuned.

BatteryBox Will Keep Your MacBook Air Running For 12 Hours

view-side

Ever been on a 15 hour flight? It’s gruelling and having some kind of entertainment (besides whatever questionable selection of movies are on board) is essential to live through it. The MacBook Air, much as it does have stellar battery life, will run dry. But if you bring this BatteryBox, it’ll provide enough power for an additional 12 hours of runtime. If you pack a MacBook Pro, that’s still 6 hours extra. Note that it won’t actually charge your battery, but will power the laptop directly. BatteryBox does have a Magsafe2 output so you can plug it directly into the machines, though there’s a USB adapter if ever you need to power something that uses that.

Finally, this little 12,000mAh/50Whr box can go through 3,000 full charge cycles and still retain 96% of its capacity after 5 years. That’s some durability, which more than justifies the $139 asking price, in our opinion.

Brunton Hydrogen Reactor Can Keep You Off The Grid For Months

F-REACTOR-BL_1024x1024

This isn’t the first or only hydrogen reactor capable of charging small electronics. Some of you may remember the Powertrekk fuel cell charger from back in 2011. But we feel like the technology has matured quite a bit since then and Brunton’s implementation is our favorite. The Hydrogen Reactor from Brunton uses disposable hydrogen cells to generate enough electricity to recharge your phone 6 times. After those 6 charges, just change the cartridge and keep going. Matter of fact, you can keep doing this indefinitely, as long as you’ve brought enough hydrogen cartridges with you. The beauty of this setup becomes apparent when you consider the weakness of other solutions in the case that you decide to be away from the grid for an extended period of time. While a portable battery pack may be enough for a few days, it’ll fall way short of the near infinite amounts of power you can generate with the Brunton unit. Each cartridge is $20 and of course that adds up to a lot, but being able to stay connected while you’re away is worth a lot more for some people. The generator itself is $170.

Super Slim External Battery Might Be Convenient Enough To Carry

Gokuusu-portable-battery

Let’s face it, the main reason external batteries aren’t as much of a runaway success as they could be is because no one wants to carry yet another bulky item in their pockets. But phones will keep running out of juice, and you’ll keep turning off Bluetooth, WiFi, brightness and whatnot to get that extra mile out of your phone. What about the Gokuusu portable battery? It’s 4.5mm thin and about credit-card sized, which means that it could fit into a wallet with ease. Sure, the 1,000 mAh isn’t going to bring a phone back to 100%, but in emergency situations, it’ll be more than welcome. The connection is done through a retractable USB cable and a set of tiny adaptors for whatever phone you carry. Better yet, it also has 4GB of storage. At 2,980 Yen ($30), it wouldn’t make much sense not to get one if you’re the type of guy who’s constantly getting home with your mobile running on empty.

World’s First Stackable Battery Pack Has Unlimited Amounts Of Power, For A Price

There are a number of situations where you might need power and be away from the mains for a long period of time. Camping? 18 hour flight? Power outage? Regardless of the specifics, some of you will not fail to notice the advantages to having something like the Exovolt Plus, an infinitely (well… not infinitely, but you know what we mean… we hope) stackable battery pack that can deliver as much power as the amount of sub-units you’re able to stack atop one another without the whole thing collapsing in on itself. You first have to buy the 5,200 mAh main battery for $89, and then you buy as many of the sub-batteries as you can afford for $50 a piece. We don’t know the capacity of the subunits, but we hope they’re in the same range as the main. It’s mostly heard to power iDevices as it comes with a 30-pin adaptor, but there’s a USB and micro-USB connector as well so it isn’t limited to that.

Yes, it’s a lot of money, but if you have the cash, you’ll be able to get yours “soon”.

Hefty Backup Battery For The MacBook Air Runs On Old-Timey C Cells

MacBook Air Backup Battery (Images courtesy Bird Electron)
By Andrew Liszewski

One of the trade-offs to carrying the slim and svelte MacBook Air is that you can’t swap out the battery with a backup if you’re away from a power source. But that doesn’t mean you’re completely out of luck. Looking like something purchased from a Radio Shack back in the 80’s this external power source for the MBA runs on 8 x C-cell batteries. They’re not as easy to find as AA’s in an airport setting or convenience store, but if you manage to find enough they’ll give you an extra 2 hours use of your laptop.

When full the backup weighs in at around 2.2 pounds, so carrying it around as a ‘just in case’ power solution pretty much ends up cancelling out how light the MacBook Air feels. And besides the fairly expensive $247+ price tag, it can only be used with Apple’s MagSafe Airline Adapter, which is an extra $50. So in this case it’s almost cheaper and easier to carry a fully charged netbook to fall back on when your MBA is dead.
