【Disaster Prevention】Returning to the basics for peace of mind! Mobile battery with cable that can be charged with AAA batteries
To prepare for unexpected emergencies, the author always carries a mobile battery when going out. While there are benefits to being reusable, it can only be used in environments where power can be secured... Hence the return to basics. I checked out the battery-operated mobile battery with a cable that can be immediately charged with AAA batteries.
Portable compact size! I want to keep it in my disaster preparedness bag.

A battery-operated mobile battery that can be used during disasters or emergencies as long as there are AA batteries available, making it a useful item for disaster preparedness. It can charge small electronic devices such as smartphones and earbuds with four AA alkaline batteries (or nickel-metal hydride batteries).

Connect the included cable or a USB cable compatible with your smartphone to charge. It can charge your smartphone to about 50%. If you keep it in your disaster preparedness bag along with spare batteries, you can charge it repeatedly.

When you hear "dry battery type," you might imagine a mobile battery from a while ago, but of course, the functionality is sufficient. It is equipped with a battery ON/OFF switch and an LED lamp that allows you to check the power supply status.

In addition to a USB-A port, it has a two-port specification with a USB Type-C port, allowing you to use your existing USB Type-C to USB Type-C cables for charging a wide range of devices.
