Detailed information

The timing of the "72-hour endurance test" is in mid-August during the extreme heat! We deliberately chose the most challenging time for the engine to conduct the test.
The Cabinet Office's policy also clearly states, "While being aware of the important 72 hours for saving lives," and it is considered that the first three days are very crucial in large-scale disasters.
In the "72-Hour Endurance Test," EcoFlow's portable refrigerator demonstrated outstanding cooling performance even during long hours of operation!
I was able to enjoy a comfortable experience with the surprisingly powerful EcoFlow portable air conditioner, despite its small size!
When the charge level of the "battery" is low, it is charged with the "generator ELSONA," and the charged "battery" is connected to the "portable refrigerator" or "portable air conditioner" for operation.
A "portable power supply," which is a "storage battery," can store electricity but cannot generate it. In preparation for disasters, I strongly feel that it is necessary to have not only a "storage battery" but also a "generator" at the same time, and to create a system where the "storage battery" can be charged from the "generator" when its remaining charge reaches zero.
The "72-hour endurance test" continues while checking in turns to see if the generator is operating at night.
In the end, it transitions into a mode of calmly performing fuel exchanges and operational checks. It has become a mindless routine work.
After completing the "72-hour endurance test," I was able to prove with my own hands that it is truly a generator that can be used safely for 72 hours.
