Prykarpattiaoblenergo explains how to use power banks correctly during frequent power outages in Ukraine, to extend their service life and reduce risks.
Storage and operating conditions
Do not leave a power bank outdoors or in a cold room with high humidity, as such conditions can cause the casing to deform and reduce the battery’s capacity. Also avoid leaving the device on a blanket or soft furniture while charging, because it can overheat due to high temperature.
Do not charge the device unattended, and disconnect it from the power source after it is fully charged. Use a good-quality cable to reduce the risk of malfunctions.
Recommendations on battery condition and frequency of use
Experts advise using a power bank to charge other gadgets at least once a week. The company’s recommended optimal storage charge level is 70−80%.
If the device’s casing is swollen, deformed or cracked, it must not be used. Other dangerous signs include a burnt or chemical smell, cracking, hissing and damaged connectors — such power banks should be set aside and no longer used.
Alternative power sources and additional information
