FAQ
Based on testing, automatic drainage is typically triggered when the accumulated condensate volume is approximately 300–400 mL. The actual trigger volume may vary slightly due to factors such as the unit's placement angle and ambient humidity.
To ensure proper operation of the automatic drainage function, please keep the air conditioner positioned as level as possible. Excessive tilting may cause uneven water distribution within the reservoir, leading to inaccurate water level detection and compromised drainage performance. In severe cases, condensate may even overflow from the edges of the reservoir.
- After automatic or manual drainage, approximately 50–100 mL of residual condensate remains in the reservoir—this is normal.
- If the automatic drainage threshold was not reached before shutdown and manual drainage was not performed, the condensate generated during operation will continue to accumulate in the reservoir, potentially leaving 100–400 mL of water.
During transport, if the unit is tilted at a significant angle, residual condensate in the reservoir may flow out from the front, rear, or side edges of the tray.
For long-distance transportation or storage, we recommend first draining residual water in a safe environment by opening the drain plug. Gently lift the front of the unit to direct the accumulated water toward the drain outlet and allow it to flow out, thereby emptying as much water as possible before proceeding with long-distance transport or storage. During handling, please keep the air conditioner as level as possible and avoid excessive tilting to minimise any inconvenience caused by water leakage.
The main reasons are as follows:
1. Reservoir geometry limitations: The reservoir has a relatively shallow slope and incorporates internal baffle structures, which prevent all condensate from converging toward the pump suction inlet. As a result, some water may remain around the perimeter of the reservoir.
2. Pump suction positioning: The pump suction inlet is not located at the lowest point of the reservoir. The lowest point, where the drain plug is situated, will still retain some condensate that cannot be evacuated by the pump.
Therefore, it is normal for a small quantity of residual water to remain in the reservoir after automatic or manual drainage. When disconnecting the drain hose, please prepare a towel or container to catch any residual water that may spill out, so as to avoid wetting the surrounding area.

2.EcoFlow WAVE 2/3 Add-on Battery (XT150 port)
3.EcoFlow portable power stations (XT150 port)
Plug it into a shore power outlet first. If it starts, the battery was fully drained.
2.Low battery discharging limit:
If the battery is below the discharging limit, plug it in to charge.
Optional: Set the discharging limit to 0% in settings. This gives you 1 extra minute of runtime before shutdown.
3.Future improvement:
A firmware update will soon improve low-battery handling for smoother operation.
Still stuck? Contact support for help! 😊
After draining, remove the tube and tilt the device backward slightly to remove leftover water.
2.Never tilt or flip the device – it may break internal parts.
3.Check battery connections if attached.
4.Turn off the device before moving.
5.Total weight ≈55 lbs (25 kg) – Don’t move it alone！
2.Avoid direct sunlight – it reduces cooling efficiency.
3.Place the WAVE 3 flat on the ground to avoid water leakage.
2.If an update fails due to power issues:
Reconnect to power and retry.
Contact support if the problem persists.
2.Plug the device into a shore power outlet, turn it on, connect it to Wi-Fi via the EcoFlow app, and update the firmware.
⚠️ Keep WAVE 3 plugged in during updates to avoid failures!
