Ensuring power supply in the outdoor field is no longer a special piece of equipment. As the number of devices we use increases, including smartphones, GPS watches, cameras, lights, and earphones, the importance of mobile batteries is also increasing
However, when outdoors, the effects of temperature and the environment in which you are using your device cannot be ignored. When camping in the winter or hiking early in the morning, in addition to voltage drops due to low temperatures, sudden temperature changes can cause malfunctions and safety concerns
In addition, in the summer, the high temperatures of leaving your phone in direct sunlight or inside a car can affect its deterioration and safety. Outdoor enthusiasts have probably experienced the following at least once: "The battery died faster than expected in the cold" or "I'm worried about leaving my phone in a car in the summer."
Still, when choosing a mobile battery
There may still not be many people who are aware of "what kind of batteries are used."
In addition to the currently mainstream lithium-ion batteries, the options for batteries themselves are steadily expanding, including those that emphasize safety and longevity, and those that are attracting attention as next-generation technologies
Therefore, Outdoor Geargin will be conducting a reader survey to find out which type of mobile battery they would like to use for outdoor purposes in the future
