Purchased on January 21, 2021, but I am selling it because I already own another one. It has been opened to check the contents, but it is new and unused. It can be used in various situations, and in these times, having one in every household is a reassuring ally. If you have any questions, please leave a comment. ■ Great for multiple uses! Compact size, making it convenient to carry and store. It is useful not only for outdoor activities but also as an emergency power source in case of disasters. ■ Cell starter (for 12V cars only) function You can easily start your car if the battery suddenly dies, and it is equipped with a multi-safety protection system, so you can use it with peace of mind. ※ Multi-safety protection system: Overload protection / Short circuit protection / Overheat protection / Overvoltage protection ※ Dedicated booster cable is also included. ■ Equipped with multiple output ports! With three types of output ports: AC/DC/USB, it is useful in various situations! Laptops, smartphones, car-mounted portable monitors, and some home appliances like small fans. It is convenient to have when you want to start them in a place without power. ■ Various disaster prevention light patterns Press the "flashlight/lantern switch button" on the top of the main unit once to turn it on, and the lighting pattern changes each time you press it. The circular flashlight part has high/low light intensity, and fast/slow flashing patterns, which can be used as an SOS signal in case of emergencies, such as outdoors. The oval lantern part, which switches last, is ideal for securing light.
