Answers by topic

Start with the problem you can see.

Confirm the battery output matches your CPAP adapter voltage, then use the machine-specific DC cable. Reconnect both ends firmly and check that the selected output remains visible on the battery display.

Humidification, heated tubing, pressure, mask leak and battery condition all change runtime. Retest for one night with comfort heat off, then use that result to plan a safe reserve.

Pass-through behavior depends on the model and charging method. Use only the documented input and keep the battery ventilated. Check your product manual before relying on pass-through overnight.

Disconnect devices, keep the battery dry and away from heat, and recharge it periodically according to the storage guidance in your product manual.

Check the battery display for an output or protection warning, then confirm the correct voltage and cable. Test the CPAP without humidification or heated tubing. If it stops again, record the display and send a short video to support.

Air travel depends on battery capacity and the operating airline. ES270 is designed around the common 100Wh threshold. ES400 AIR may require airline approval. ES720 and ES960 families exceed common passenger-aircraft limits.

Use the charging input and charger listed in your model manual, and make one full charging attempt on a working wall outlet. If the display stays at 0%, stop trying unrelated adapters and send us the battery model, charger label and a short video.

Use the supplied adapter on a stable wall outlet. Record the input reading, battery percentage and any icon shown when charging stops, then check that both connectors are secure. One continuous video helps us tell whether the issue is the adapter or the battery input.

No. Unplug an adapter that is damaged, deformed, smoking or unusually hot, and do not reconnect it. Send us the battery model and a clear photo of the adapter label so we can confirm the correct replacement.

AirCurve is a BiPAP platform and can demand more power than a typical CPAP, especially with humidification or heated tubing. Confirm the exact model, documented cable and power rating. Test during the day before overnight use and contact support if the warning remains.

Only use pass-through operation when the exact model manual permits it and the documented charger can cover the connected load. Keep the battery ventilated and periodically verify charge state. For long-term standby use, follow the model's storage and maintenance guidance.

Open Flight documents and choose the model printed on your battery. ES270 and ES400 AIR reports are available as immediate PDF downloads. The report confirms transport testing; the operating airline still makes the final decision about carriage.

Read the model label on the CPAP and the output line on its original AC adapter. Send clear photos of both labels if you are unsure. Connector shape alone is not enough to confirm voltage or cable compatibility.

Email us the purchaser email address, approximate purchase date, sales channel and battery serial information. We will first locate the purchase, then explain the available warranty or replacement options.

Reply to the existing support email so your case stays together. We will send the carrier and tracking number once the replacement ships. The storefront tracker may not show replacements created manually by support.

Start with the battery model label, then show the charger label, cable connection, display and the exact button sequence or failure. Keep the video continuous and remove unrelated personal information from view.

Usually, but comfort heat can use a large share of the available energy. Test your exact pressure, humidifier and heated-tube settings for one full night before travel or an outage, then keep a reserve instead of relying on the maximum published range.

Follow the exact model manual and inspect the battery periodically rather than leaving it untouched for months. Recharge before the level becomes very low, keep it dry and cool, and do not store it connected to a CPAP or charger unless the manual explicitly permits that use.

Use the cable listed for the exact CPAP model and verify the required voltage and polarity. A tip that physically fits can still be electrically wrong. Stop and send label photos to support if the documented cable cannot be identified.

Stop immediately if the case swells, becomes unusually hot, smells abnormal, has damaged wiring or needs force to connect. Disconnect the CPAP and charger, keep the battery away from heat and combustible material, and contact us with clear photos.

Use the product planning range with humidification and heated tubing off as a starting point. Pressure, leakage, CPAP model, temperature and battery condition change the result.

Match the complete CPAP model and adapter voltage in the compatibility guide. Connector shape alone is not enough.

Charge fully, verify voltage and cable, then run one complete night using the settings you plan to rely on.

Official website purchases include a 5-year warranty, lifetime product support, 30-day free returns and free U.S. shipping.
