Car Vent Seal EcoFlow Magnetic Version EFA-WAVE3CARVENTSEAL — magnetic car vent seal for portable power stations and Wave 3

Magnetic Car Vent Seal EcoFlow EFA-WAVE3CARVENTSEAL is a vehicle accessory designed to create a secure, weather-resistant seal around a partially opened window or vent to pass charging cables for portable power stations such as the Wave 3. The magnetic version uses integrated magnets to attach to metal window frames or door edges, limiting drafts and protecting the interior while allowing continuous charging or power delivery when the vehicle is parked or in transit.

Advantages

The magnetic attachment provides quick, tool-free installation and a reliable hold on metal surfaces without permanent modifications to the vehicle. The seal material is made to fit around cables and minimize air exchange, helping to reduce noise, dust ingress and heat loss. Designed specifically for use with portable power stations and the Wave 3 model, the shape and cable passthrough accommodate common charging leads while maintaining a stable, low-profile fit.

Suitable for

• Running or charging portable power stations from inside a vehicle
• Temporary power delivery during camping, road trips or work on the go
• Sealing a vent or slightly opened window to pass one or more cables without letting in drafts
• Use with metal-framed windows, doors or other vehicle surfaces where magnets can attach

Key specifications

• Attachment type: built-in magnets for metal surfaces
• Compatibility: designed for portable power stations and cable sizes used by Wave 3
• Seal style: flexible passthrough sleeve to reduce air exchange around cables
• Material characteristics: weather-resistant, dust-reducing construction
• Fit: low-profile design suitable for partial window/vent openings

How to use

Partially open a vehicle window or vent to the minimum height required for the charging cable. Position the magnetic edge of the seal against a clean metal surface near the opening so the magnets hold the seal in place. Feed the charging cable through the flexible passthrough sleeve, then close the window or adjust the vent to a secure position while ensuring the cable is not pinched. Verify the seal sits flush and that the cable has enough slack for safe connection to the portable power station. When finished, remove the seal by pulling the magnetic edge away from the metal surface and stow it for future use.

Recommendations

Use the magnetic seal only on clean, painted or bare metal surfaces that allow magnetic attachment. Avoid using the product on non-metallic frames or heavily contoured areas where full contact is not possible. Inspect the cable and seal for damage before each use and do not force the window closed tightly over the cable to prevent pinching. Store the seal in a dry place when not in use and avoid prolonged exposure to extreme weather to maintain material performance.
