5 Ways To Charge Your Phone In An Emergency

how to charge your phone in an emergency


Smartphones can be important tools in an emergency. Besides providing the chance to call for help and other emergency features you phone may offer Your iPhone Could Save Your Life: 6 iPhone Emergency Features Your iPhone has many survival tools that can help you out in a pinch. Here are some essential iOS features for emergencies. Read More , a phone can act as a flashlight, compass and GPS. But all of a phone’s functions rely on the battery and the features most useful in a pinch are the ones that consume the most charge.

Once the battery is flat, the phone becomes nothing more than a lump of plastic and metal. There are, however, a few ways to charge your phone in an emergency, when a power outlet or computer isn’t available. These solutions range from mundane to truly innovative.

Car Charger

how to charge your phone in an emergency

Let’s start simple.

Car chargers are cheap, widely available for all sorts of devices and vehicles, and will work so long as there’s a vehicle nearby with an energy provider.


Most car chargers work in the same way, so buying a specific version isn’t important. Just remember that iPhones will need a compatible charger or an adapter. Also keep an eye out for dual-USB chargers, which are handy if you’d like to charge two phones or a phone and a second device.

Backup Battery

In many situations a car charger is all you’ll need. But what if a car isn’t available, is out of fuel/battery, or you don’t want to waste gas on charging a phone? That’s where a backup battery comes in.

These products are literally large batteries with ports for connecting phones or other USB device. Those designed to charge smartphones are usually no larger than one, so they’re easy to store in a drawer, backpack or glovebox. And while not cheap, batteries large enough to fully charge two phones can be purchased for under $50.


A backup battery is a temporary solution, however. Eventually it too will run out of charge, so you’ll be left back at square one. Batteries also lose charge over time (even when not in use) and can be damaged by extreme temperatures.

Solar Charger

Unlike the first two options, a solar charger fully solves the problem. You can theoretically use a phone indefinitely without access to central power if you have a solar charger. All that’s required is access to the sun, and even a moderately overcast day will produce enough energy to charge your phone.

Size can be an issue, however. While pocket-size chargers are sold, they don’t work well. A larger folding charger is needed for reliable power. Cost can be an issue, too, because large panels sell for between $100 and $200 online. Still, no other option can match the versatility and reliability of solar.


Hand-Crank Charger

You’ve probably heard of hand-crank flashlights, but did you know there are hand-crank chargers? Yep, it’s a thing, and you can buy one for $60 online. Hand-crank chargers work by converting the energy of your crank into charge, which is then transferred either to your phone or an internal battery. This means they always work. If you can crank, your phone can charge.

Don’t expect it to charge quickly, however, unless there’s also charge stored in the internal battery. Most modern smartphones will require a few minutes of cranking before they have enough charge to send a text, and any real conversation demands a good ten to twenty minutes twirling away. These problems make hand-crank chargers an option of last resort.

BioLite CampStove

Here’s an idea. Instead of charging your phone with something built for only that purpose, why not charge while performing another essential task? Like, say – cooking!

That’s what the BioLite CampStove offers. Unlike most camp stoves, which run of small canisters of fuel (like propane), the BioLite stove is engineered to run off almost any flammable biomass. Twigs, leaves, pine cones – this stove can burn it all. Once the fire starts its energy can be harnessed to charge USB devices.

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


These five options cover many situations. There’s no single choice that is best in ever scenario, but all are reliable. If you can only have just one besides the car charger (really, everyone should have a car charger, even if you don’t own a car), I recommend picking a hand-crank charger with internal battery.

    It's not an emergency if you can wait 4 -8 hours for your device to charge. I want an INSTANT backup power source. Why isn't my tablet designed so I can (repeatedly) switch out the dead battery with a fully charged backup battery. I received a myCharge charger as a gift and it takes hours to charge...and not usually to 100%. I got confused. I thought when fully charged it was an instant backup power source.... not a device to charge the tablet. I can charge at home. If camping in the boonies who wants to wait hours until it charges the tablet.

    Wow, how interesting these ideas are, Matt! I really like the idea of the BioLife stove. Just an hour or so ago, I saw a TED video on using fecal matter (yeah, yuck, I know) for cooking fuel. In some areas of the world there are people doing just that. Very interesting and talk about real ecology, right? Thanks for the article.

    If you want an all-in-one backup option that is camper friendly, GoalZero makes a combo kit that is a solar panel plus a 4xAA battery pack. You can use the solar panel to charge the battery pack, then use the battery pack to charge your phone (or just use the AAs in other stuff). AA's dont have enough juice to fully charge a smartphone, but it can give you a boost in a pinch.

    Charging directly from solar does NOT work well; do it from a battery pack instead. Phones like a steady current, and one cloud can cause your phone to dip in and out of charging mode. Given that phones often turn their screens on when they start charging, this can cause your phone to wake/sleep itself to death.

    I have a charger which gets energy from both sun and wind. It cost just over $30 with shipping and handling from some close out list I get. I like the notion of a hand crank and I will look into a crank adapter for the wind blades. I have a folding bio-mass stove and I wonder if just the charger is available as an add on.

    If I have the adapter cord, it's not an emergency.

    If you want to address a real emergency, tell me how to charge it when I don't have the cord or access to a replacement.

    • Guy McDowell

      That's not an emergency, unless you need your phone to call the police, fire department, or ambulance. Then it's an emergency.

      What you've described is just poor planning. It can be overcome by asking to borrow a phone or finding a pay phone. They're few and far between, but they do exist.

    In an emergency???? Gee, all these options suggest having planned alternative options for charging your phone, so by definition they NO LONGER constitute an "emergency". The headline is the typical illiterate abuse of the English language seen in the media these days. All hype, no logic or intelligence.

    • Guy McDowell
      April 15, 2013 at 7:24 pm

      Planning ahead does not negate the emergency, it just makes it more bearable and hopefully easier to recover from.

      If you were looking for something a little more MacGyver-ish, might I suggest that you take some copper wire from another device, connect it to a low-amp 12v battery and put the wires to the appropriate contacts on the battery port?

      Or you could make an array of batteries that puts out about the same voltage as your phone requires and connect that to the battery terminals.

      Or Google 'earth batteries' and try powering your cell-phone like that. Of course, if it comes to that point, having a cell phone won't matter much because the zombies will have eaten you.

    • Charlie O.
      April 16, 2013 at 5:41 pm

      Yeah. I see what you're on to, James. Though I need to say that SOME of these options could be used in an emergency, such as hand crank or solar, the rest do seem to insinuate some foreknowledge of the impending inconvenience, and therefore not much of an emergency. Still, if a catastrophic event simply left you without utilities, charging your phone in your car would be a viable solution and it is, after all, an emergency. However, at that point, your phone is a camera-compass-unassisted GPS because in a REAL emergency, there won't be any cell towers working.

      To your credit, there is a serious washing down of both vocabulary and, more importantly, hype based and misdirected focus and intent in much of what gets 'written' in any media. Sure, writers have the right to use catchy titles, but these days there's mostly a disconnect between the title, the opening ideas and often enough, the various points that comprise the body of the work. I'm getting the idea that MUO may be somewhat of a stop-over for writers who didn't learn to write in collage or (Heaven forbid!) high school. Its nice if you've decided to pick a new direction in life, or add a bullet point to your resume, or you were bored... but there are forums and outlets that can help you BEFORE you get started. That actually brings us to wonderful place of irony - if you're writing an article on preparedness, and you're not prepared to write, which gadget do you plug in at that point?

      Lastly, as more fuel for your argument, there was an official talking, very unnecessarily, on the news after the tragedy in Boston, and he was asking for help from the local citizenry. I was watching with my kids. He asked the people to "remain vigilant", I'm assuming because the investigators need help, which is fine. But, I had to have a 20 minute discussion with the kids on vigilance vs. reaction. It is absolutely true that our understanding of our own language is spiraling downwards into Newspeak, but we're doing it to ourselves. We need lingual vigilance before we end up having to react.

    I truly didn't know about the hand crank, solar panels or camp stove. That last one is a marvel. To think you could cook dinner and charge is cool.

    Well, I guess it depends on your definition of emergency, but I've noticed in shopping malls a lot of the vending machines and kiosks are offering courtesy outlets and USB ports to charge your device while you wait.

    Got a Backup Battery as a gift on fair for some years ago and it still work even ig it takes tie to charge. Do not use it very often. Would like to get a Hand-Crank Charger but $ 60 is a bit of money and knowing how much I have used the Backup Battery I can not justify a purchase. Car Charger? Well, when I have run out of battery I have been miles away from any car.

    I would rather throw my phone very high in the air and covert my body's chemical energy into kinetic energy and the phone will get charged automatically with such technology. This will make good use of durable Nokia phones for playing catch and throw games while charging the phone. Jokes apart, thanks for the great article.

      In theory, that is possible. There are electronic devices that convert any vibration into an electrical output. Perhaps you're onto something there.

    There is also:
    The power pot is similar to biolite in many ways, except you have many more fuel options than you would with Biolite.

    Also eton makes a cheaper model without the extra battery backup that still has the crank charger.
