You don't have to worry about running out of batteries because you generate electricity manually! Introducing the "manual power generation 2 LED light" found at 100 Daiso.
Daiso Manual Power Generation 2 LED Light
An indispensable item "flashlight" in the event of a disaster such as a power outage. However, if the battery runs out in an emergency ... Many people will feel such anxiety.
Daiso's "manual power generation 2 LED light" introduced this time is a light that can generate power by repeatedly holding and releasing the main body.
The size is about 10 x 5 x 2 cm thick. It is a mini size that fits comfortably in the palm of your hand.
There are two buttons on one side. Press the button above to turn on the light. This is due to the built-in battery. However, the built-in battery cannot be replaced, so it seems better to recognize it as an incidental function.
Built-in battery (non-replaceable)
When you press the button below, the "power generation grip" pops out like a feather from the opposite side. Grasp this and push it into the main body → release your hand and return it to the original position, and two LED lights will light up.

Power generation grip appears
Repeat gripping and releasing like muscle training
It lights up only while you repeatedly hold and release it. In other words, when using it as a light, you will keep working one hand all the time. The grip is light, but it seems to get tired after a few minutes.
It disappears when you stop your hand
Also, the rotation noise of the gears is quite good. I wonder if it's okay for emergency use, but it may be a little worrisome for everyday use. It's not enough to interfere with talking to people nearby.
A mini light that is safe for manual power generation without the need for batteries. However, since it is a 100-yen product, it is uneasy to rely on it, and the light is not so strong. It is recommended to add it to disaster goods as a spare.
