SpareOne has become a game-changing preparedness device since its 2012 launch when it gained national notoriety for its innovation and ability to keep the lines of communication open when power is completely unavailable or inaccessible. In the event of natural disasters or emergencies or as a back-up in the glove box, SpareOne provides an unparalleled lifeline. Cellphones are typically powered by rechargeable batteries, which have the advantage of being able to be charged and discharged hundreds of times. However, they require cords, adapters and electricity to be recharged. In contrast, SpareOne uses a single standard AA battery, the only cellphone to do so. It took a total of two years to perfect the power-management design to enable it to function with one AA battery—any rechargeable, alkaline or lithium AA. In the case of SpareOne, when stored and unused, the battery will last for up to 15 years. That means that a SpareOne stored in a car, in a first-aid kit, in a backpack or at home will be fully charged and ready to use when an emergency or a disaster happens. That single AA battery provides up to 10 hours of talk time when in use. SpareOne also contains a flashlight on top that provides 24 hours of continuous light; a dedicated 911 dial button to alert authorities, which works with or without a SIM card; the ability to preset nine speed-dial numbers; and a talk-through resealable waterproof bag with a humidity-proof seal. The floatable bag operates in extreme temperatures between -22 and 140 degrees Fahrenheit and protects against water damaged when submerged for up to 30 minutes at a depth of 1 meter. SpareOne was also designed with room to accommodate a few small items, such as credit cards, bandages and other small items. Designed to be the ultimate safety and communication device, SpareOne works independently of a specific cellphone carrier with no monthly fees. Users simply insert a SIM card with credit to begin making calls at local rates; emergency calls can be made without a SIM. SpareOne is SIM-unlocked, so it can accept SIM cards regardless of the GSM operator; micro-SIM adapters are also available so iPhone users can use their iOS SIM. Consider the 8 million people were left without power for weeks after Hurricane Sandy in November 2012. They were unable to charge their smartphones and were completely out of reach, unable to contact loved ones, call for help or schedule services. In that situation, as well as in many others, SpareOne could have played a big role in reconnecting families and service providers, delivering assurance, confidence and safety.
