The CPAP Backup Battery Zopec Explore 4000 is designed to deliver uninterrupted therapy during power outages and travel. With built-in online UPS AutoSwitch technology, this CPAP Backup Battery keeps your machine running without interruption if mains power fails. Simply plug your CPAP into the battery and leave it connected for continuous protection.
Designed for portability and reliability, the Explore 4000 provides pure sine wave AC output for broad compatibility with CPAP and BiPAP devices. Its FAA-compliant 130 Wh capacity makes it suitable for carry-on travel while still delivering dependable overnight runtime for CPAP use without heated comfort features.
The Explore 4000 features double-conversion online UPS technology. This allows seamless power transfer in a fraction of a second, helping maintain consistent therapy without unexpected shutdowns.
In addition, the pure sine AC output ensures compatibility with sensitive respiratory devices. You can use it like a standard wall outlet without requiring brand-specific DC converters.
This CPAP Backup Battery is lightweight and suitable for flights under FAA regulations, as it remains below the 160 Wh limit for carry-on batteries. It is ideal for road trips, flights, or temporary power interruptions at home.
For longer travel, humidity and heated tubing should be reduced to extend runtime.
