Plan V Uses 9V Batteries To Charge Your Phone

Plan-V-Failsafe

You may not know it, but there’s likely a drawer somewhere in your home where you keep all kinds of odds and ends that you need around the house. Screws, butterfly fasteners, IKEA wrenches, a hammer, and probably a couple 9V batteries for your smoke detector. Well it turns out if you get the Plan V, they’ll have another potential use: charging your phone. Plan V is a tiny dongle that takes a 9V battery and uses its power to charge your mobile device. It’s great if the power is out for an extended period and you really need to charge it. Or if you’re out somewhere and are desperate for some more talk time. It’s small enough to serve as a keychain, and costs all of $12… if it gets made. It’s a Kickstarter at the moment, and until they reach their funding goal they’re only making a Micro-USB version. They’re still far from the goal so nothing is sets in stone, but you can help them out with a pledge if this looks like something you’d use.

Deal Of The Day: 152 Duracell Batteries For $60

redesign_duracel_mf

If you’ve ever stopped by a convenience store on the way home to buy just a pair of AA batteries, you’ll know just what a racket that is. Costing as much as $5-$6 a pair, these things can get ridiculously expensive if not bought at the right time and place. Like now. You’re looking at a kit of 100 AA and 52 AAA Duracell batteries, and they’re going for $59.99. That works out to around 34 cents a piece, rather than the $2-$3 they can sometimes cost. The batteries are good until 2019, so it’s not like you’re buying old, unsold stuff.

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.
