[Motivation for Development] Disaster Prevention Emergency Power Supply 'BPS'

[Motivation for Development] Disaster Prevention Emergency Power Supply 'BPS'

I want to save charging refugees! I aimed to create an emergency power source that can be reliably used even in emergencies!

Natural disasters such as earthquakes, heavy rains, and typhoons occur every year across Japan. When a disaster strikes, the lifeline that will save your life is communication means. Disaster victims realize how important it is to secure power during emergencies. Therefore, we thought it necessary to ensure that charging can be done sufficiently in nearby locations to respond to large-scale power outages caused by massive earthquakes and typhoons. First, we designed a system that can charge more smartphones in limited indoor spaces while also serving as lighting. Since fossil fuel and gas generators cannot be used in indoor evacuation shelters, we have adopted a portable power source that does not emit carbon monoxide. With a focus on size and weight that is easy for anyone to use, as well as necessary accessories and cables, we have finally completed the "Disaster Emergency Power Supply." *For more details, please refer to the PDF materials or feel free to contact us.

Emergency Power Storage System Mobil C2 Power

Emergency Power Storage System Mobil C2 Power

A budget version of the 'Mobil C2 Power - Medical' developed as a movable power source for medical devices.

Completely independent AC power supply Since it is independent from commercial power sources, you can use your equipment with peace of mind without being troubled by radiation and electromagnetic noise from power lines. Very clean output waveform The output waveform is a pure sine wave. It is not a so-called pseudo sine wave (square wave, trapezoidal wave), so it can be used without any issues with devices that have built-in PFC. Very quiet startup sound Unlike engine-driven generators, it uses a battery, so you can use it with confidence even in noise-sensitive situations. Compliant with RoHS directive Note: It is not waterproof, so please refrain from outdoor use in rainy conditions.
