The product can be used to power a home ventilator (home CPAP) that does not have to be continuously monitored by professionals. Please follow your doctor's instructions and consult with the manufacturer for restrictions on the use of the equipment. If it is used for general medical equipment, please be sure to monitor the power status to ensure that the power does not run out.19. When in use, power supply products will inevitably generate electromagnetic fields, which are likely to affect the normal operation of medical implants or personal medical equipment such as pacemakers, cochlear implants, hearing aids, defibrillators etc. If these types of medical equipment are being used, please contact the manufacturer to inquire about any restrictions on the use of such equipment. These measures are fundamental to ensure a safe distance between medical implants (for example, pacemakers, cochlear implants, hearing aids, defibrillators, etc.) and this product while in use.20. When the power supply is connected in the normal mode to a refrigerator, the power supply may be automatically shut down due to the power fluctuation property of the refrigerator. If the refrigerator stores medicines, vaccines or other high-value items, it is highly recommended that you set the AC output to "Never Turn Off" through the EcoFlow app when connecting the power supply product to ensure a continuous power supply. Users should pay attention to the power consumption of the power supply.21. Do not put ﬁngers or hands into the product.22. To reduce risk of damage to the electric plug and cord, pull the plug rather than the cord when disconnecting the power pack.23.
