Earthquakes, hurricanes, career-changing phone calls... whenever you need a working phone when no power is available, the SOSCharger is your solution.

Today, we rely heavily on our mobile phones for every day communication. We often forget that these same devices are our lifeline in an emergency. This is why we designed a solution that will bring power to your devices no matter what the world throws at you.

Power. Yourself.

The new SOSCharger, the portable self-powered mobile phone charger.

Why SOSCharger?

An issue with some hand-crank products on the market is they lack power output for modern smartphones, especially the iPhone. Many current solar solutions also don't collect enough light to work effectively and light is not always available in an emergency. We have a lot of experience with this technology. Our engineers developed a solution that is compatible with every brand of mobile phone and other products utilizing the USB-standard power source.

The solution? We incorporated a 1,500 mAh Lithium Polymer battery inside the device.

What’s self-powered mean? 

The SOSCharger features a powerful built-in generator. If you need power just turn the handle; 3-5 minutes of winding gives you 5-12 minutes of talk time.* However, there’s more to it than this.

How Does It Work?

You can charge the SOSCharger emergency cell phone charger with your standard USB wall charger; the same one that came with your smartphone or Bluetooth device. We include the micro-USB cable. Once the battery is charged, the SOSCharger acts as a backup power source for your USB-powered devices. You can charge your phone, your Bluetooth headset or even your USB-powered fan, simply by plugging in your standard charging cable to the standard USB port on the SOSCharger. This means the SOSCharger works with all modern smartphones, including the iPhone, in addition to iPod, Blackberry and Kindle.

If you’re stuck on the train, plane or somewhere that A/C power is not attainable, you can charge your device with your own personal, pocket-sized battery backup solution.

Then there’s the generator part.

The incorporated hand-crank turbine, utilizes a powerful generator, combined with a long-handle for more leverage and easy turning. If you run out of internal battery power, or you just want to keep the battery topped off, you can turn the handle to charge it up. Just turn the handle and the battery charges. We’ve included an indicator so you know when it’s charging and how much juice you have in the battery. What could be easier?

We designed the SOSCharger to be stylish and elegant, while easy to hold. With its long handle and finger grip, the hand-crank of the SOSCharger is super easy to operate. The location of connectors makes it easy to charge without the cables getting in your way. The indicator lights are visible while you're operating the charger.

Easy to Use.

To operate the SOSCharger, simply plug your device into the standard USB power port and turn the power switch on. The SOSCharger's internal battery can be recharged simply by turning the handle, while simultaneously acting as a traditional power pack. Just plug it in to any A/C adapter with USB output to keep it topped off.

About the size of an iPod Classic, the elegantly shaped SOSCharger feels great in your hand!

We’ve spent over a year developing this new model, resulting in a product with the best combination of capability, quality and value. The product has been tested extensively and we know it will offer years of reliable backup power support. Kickstarter supporters will enjoy a 2-year exchange guarantee on the SOSCharger from any factory defect (not including physical damage).

Use Examples.

  • Emergency Preparedness Kits
  • Camping/Backpacking/Hiking
  • In the Car - keep one in the glovebox
  • In the house - plug in a USB light for use as a flashlight
  • In your computer bag or briefcase - never miss an important call
  • Vacation suitcase - be prepared for unforeseen events
  • Power any 5-volt USB device you can imagine (5W or less)

The Backstory.

Development of this project started many years ago with the first iteration of the SOSCharger Hand-Crank cell phone charger. Our goal was to create an entirely new way to charge cell phones off the grid.  We had great success with our original self powered charger. Over the years we've learned so much from our experiences, and customer feedback. Through this organic learning process, design improvements have been a constant consideration since the first SOSCharger launched. After many CAD drawings and prototypes, we've developed the best design possible for the next generation SOSCharger.  We're confident it is ready for production and with the feedback we received from experts at the 2013 Consumer Electronics Show, we know it's ready for you!

Get one (or more).

We think you’ll love the SOSCharger as much as we do and we need your help to make it a reality. Help us here on Kickstarter and you can be charging your devices from anywhere. The design is complete. The manufacturing is ready to begin. We need your help to get the custom molds created and to begin production.

There's some great pledge offers and packages to help make the SOSCharger a reality. 

Thank you for your help and keep watching for updates. We’re really excited to get the SOSCharger into your hands.

Risks and challenges

From a technical standpoint, the project is complete, meaning the electronic and mechanical components are specified. Production issues may arise, including creation of molds, fit and finish quality inspections and color/graphics implementation not being to our high standards. U.S. Customs could delay importation for a variety of reasons. We don't expect this, but it is a possibility. It is also possible that our manufacturing target date may not meet its schedule. The contract manufacturer may have capacity issues with other clients or component availability (such as batteries). Any of these scenarios could delay the project's ship date by 30-45 days. There are still design and manufacturing challenges ahead. To insure quality control, in the event of a component sourcing problem or to insure functionality, changes may be made to the specifications of the SOS Charger at any time. We may have to make changes in materials or components used in the final product. We'll make every effort to insure the SOSCharger is the best product possible and delivered on time, but circumstances may arise that are beyond our control.

Learn about accountability on Kickstarter


  • We’ve received many requests from backers to be rewarded with more than one SOS Charger per pledge. It just makes sense to have more than one charger - one for the home, car, briefcase/computer bag, survival kit, etc. It also makes a great gift!

    If you’d like more than one SOS Charger please increase your pledge by $35 for each additional charger for USA and Canadian orders. For International orders, please increase your pledge by $40 for each additional charger.

  • Yes, you can charge another power pack. One of the coolest design features of the SOS Charger is it's ability to deliver USB standard, regulated output. This allows it to charge just about any device that has a USB (5watt or less) input.

    The SOS Charger can also accept a charge from an external power pack, solar panel or any device that outputs power via USB.

  • We thought a lot about design and size of the device. Holding a lot of various devices in our hand, we decided on a product that was roughly the size of an original iPod, but thicker for better grip-ability. In order for the generator to effectively function, it had to be of a certain size and output capability. Combining design, usefulness and functionality, we sought out to find the largest battery we good fit in the package. Our early prototype at 800mAh, but battery technology has caught up to our needs and we were able to increase to 1,500mAh. At this larger size, most smart phones should enjoy an 80% charge from totally dead. Our original goal was to recharge a phone at least 50% from dead. Recharge performance improves dramatically if you charge when your phone reaches 20% or more remaining battery. Lithium polymer batteries charge more efficiently when there's some power remaining in them.
