●Frequently Asked Questions
Q. What is the self-discharge rate when not in use?
A. Around 20% in 6 months.

Q. What is the remaining battery level at which the battery deteriorates the least?
A. The remaining amount is around 40%.
If the battery is stored at 40%, it will reach 20% after half a year and 0% after a year, making it unusable in the event of an emergency.
Recommended long-term storage at around 60-80%. Even if this is left for 6 months, the remaining amount is 40 to 60%, which is suitable for storage and can be used in an emergency.
A better method is to use a portable power supply once a month or so.
At that time, if you check if you can supply power and charge, you can rest assured even in an emergency.

Q. How much standby power does the EB50 use and how long does it automatically turn off?
A. Standby power consumption is as follows. Main power ⇒ 2W or less DC power ⇒ 2W AC power ⇒ 7-9W DC+AC power ⇒ 12W
Also, if only the main power is ON, the main power will automatically turn OFF after 60 seconds.
If DC/AC is on, the power will not turn off automatically, so turn it off manually.
