emergency charger for samsung galaxy s3

Smartphones can be important tools in an emergency. Besides offering the possibility of asking for help, a phone can act as a flashlight, compass and GPS. But all functions of a device depend on the battery and the most useful features in a pinch are consuming office more.
Once the battery is discharged, the phone becomes nothing more than a piece of plastic and metal. There is, however I some ways to charge your phone in an emergency, when a computer or power outlet is not available. These solutions range from the mundane to truly innovative.

Five easy steps for emergency charging phones

Car Charger

Let's start simple.
Car chargers are cheap, widely available for all types of equipment and vehicles, and work whenever there is a nearby vehicle with an energy supplier.
Most car chargers work the same way, so buying a specific version is not important. Just remember that iPhones will need a charger or an adapter bracket. Also keep an eye out for dual USB chargers, which are useful if you want to charge two phones or a phone and a second device.

Battery Backup

In many situations a car charger is all you need. But what if a car is not available, run out of fuel / battery, or do not want to waste gas charging a phone? That's Where to eat in the battery.
These products are literally large ports for connecting batteries with phones or other USB devices. Those designed for charging smartphones usually no larger than one, so they are easy to store in a drawer, bag or glove compartment. And although it's not cheap, batteries large enough to fully charge two phones can be purchased for under $ 50.
A battery backup is a temporary solution, however. Also eventually run out of office, so he was allowed to start from scratch. Also batteries lose charge over time (even when not in use) and can be damaged by extreme temperatures.

Solar charger

Unlike the first two options, solar charger fully solve the problem. You can theoretically use a phone indefinitely without access to the power plant if you have any solar charger available. All that is needed is access to the sun, and even a moderately sunny day will produce enough energy to charge the phone.

Size may be a problem, however. While pocket chargers are sold, they do not work well. Larger for reliable power folding charger is needed. The cost can be a problem, too, because the large panels are sold for between $ 100 and $ 200 online. Still, there is no other option can match the versatility and reliability of sun.

crank charger

You've probably heard crank flashlights, but did you know there are chargers crank know? Yes, that's one thing, and you can buy one for $ 60 online. Crank chargers work by converting the energy of your crank position, which is transferred is then an O on the phone or an internal battery. This means that always work. If you can boot, the phone can be charged.

Do not expect that loads quickly, however, unless there also charge stored in the internal battery. Most modern smartphones require a few minutes of starting before they have enough charge to send a text, and any real conversation requires a good ten to twenty minutes circling away. These problems make boots crank an option of last resort.

BioLite campstove

Here's an idea. Instead of charging the phone with something constructed by only That purpose, why not charge while making another essential task? Like, for example - the kitchen!

That is what provides the BioLite Campstove. Unlike most camp kitchens, ranging from small boats fuel (such as propane), the BioLite stove is designed to work out almost any flammable biomass. The twigs, leaves, pine cones - esta stove can burn everything. Once the fire starts SU energy can be harnessed for charging USB devices. Or make dinner.

The BioLite sell or $ 129.95, which is a bit expensive. And while small for a camp stove, this is by far the largest device on your list. But if you can find storage, or are thinking of the camp anyway, esta stove is a great way to keep your phone charged.


conclusion
These five options cover many situations. No single option is best ever at that stage, but all are reliable. If you can only have one addition to car charger (actually, everyone should have a car charger, even if you do not own a car), I recommend choosing a crank charger with internal battery.
