[Power Outage Measures] For those who have a new coronavirus vaccine refrigerator, unexpected long-term power outage measures can be addressed with a medical emergency small storage battery!

**Power Outage Measures** ▲ Emergency power supply and backup power for ultra-low temperature freezers that store COVID-19 vaccines, etc. ▲ Provides power to ultra-low temperature freezers for 10 hours without interruption during a power outage (based on a power consumption of 300W). ▲ High output of 1500W! Capable of handling inrush current. - Cases of vaccine disposal due to power outages are occurring frequently. Due to insufficient power capacity, freezers for vaccine storage may fall into power shortages, or unexpected power outages may cause freezers to stop, leading to the inability to maintain the appropriate storage temperature, resulting in frequent cases of vaccine disposal. CONNEXX SYSTEMS' emergency small storage battery is originally designed for emergency power supply in facilities that freeze cells and specimens, developed to handle inductive loads. It can provide power to ultra-low temperature freezers and refrigerated storage for approximately 10 hours without interruption. (Based on a power consumption of 300W). It is a portable model with large casters, making it possible to bring it to vaccination sites. It can continue to be used as a backup power source for important equipment even after the COVID-19 pandemic is over.
