Yes, you can have the battery plugged into a wall outlet and power the CPAP at the same time. The Zopec battery range was designed as medical backup power. The CPAP will run and the battery will stay 100% charged.  When the battery is plugged into the wall outlet, the CPAP machine draws power from the wall outlet and bypasses the battery. In the event of a power outage, the CPAP machine will seamlessly change to battery back up without disruption to therapy.

For a battery capacity of 100 Wh and under, you don't need to ask the airline for approval and there is no limit to how many you can bring on the airplane. This applies to Model EXPLORE Mini (97 Wh).

 It is best to just let it sit. When you need it, charge it overnight to full charge and the power bank will reset itself. The battery will be ready to go for camping.

Here are some more details for reference. All lithium-ion batteries or power banks will deplete over a few months due to leakage current. It will just need to be recharged overnight and the power bank will reset itself. This initial charge is slow to reset the power bank. After that, it will charge faster. Our batteries have premium Panasonic cells inside and sitting does not hurt our power banks. This is not the case for many other brand batteries with less quality cells.

When you turn it back on in a few months, the indicator may show around 40% - 65% charged but it is depleted. Just recharge overnight to full and the battery will reset itself. Depending on the model, it might be about 5-6 hours before the charge indicator is correct. This is only the case if it sits for a long time and the battery is depleted by leakage current. Otherwise, the charge indicator will always be correct if used frequently.

The universal power supply comes with every battery. Each power bank purchase includes the battery, Universal Power Supply, Protective Microfiber Bag, User Manual and Nice White Storage Box. 

Several factors impact the run time of the battery.  Some common ones include using the heated humidifier features, having a high leak, and having high pressures. 

For best results, turn the heat off on your humidifier and heated tube and ensure your mask is sealing well. 

In optimal conditions, you can expect that the battery will last about 2 nights on a single charge.  Consult the battery usage charge for your brand here.
