The EcoFlow 400W portable solar panel weighs 16 kg (35.3 lb) and folds into an adjustable carry case. Its unfolded dimensions aren't specified here, so confirm the full setup footprint before you plan around a tight campsite, RV compartment or home storage spot.
The EcoFlow panel is included with the DELTA Pro in the bundle reviewed here. EcoFlow says one panel can recharge the DELTA Pro in 11 hours, but compatibility and real charging time depend on your setup and conditions.
Is the EcoFlow 400W portable solar panel worth considering?
The EcoFlow 400W panel is worth considering if you want a foldable panel packaged with the DELTA Pro and can confirm the panel will fit your setup. Its weight is stated, but the unfolded dimensions aren't, which makes planning its working area harder.
EF ECOFLOW Solar Generator 3.6KWh DELTA Pro: Best for a bundled EcoFlow setup
- 400W foldable panel
- Panel weighs 16 kg (35.3 lb)
- Adjustable carry case
- DELTA Pro power station included
A bundle for shoppers who want the EcoFlow panel and DELTA Pro together. The panel is foldable and has an adjustable carry case, but confirm the panel's unfolded footprint and your setup needs before choosing it.
Pros
- Includes a 400W foldable panel
- Adjustable carry case
- DELTA Pro has 15 outlets and ports
Cons
- Panel's unfolded dimensions aren't specified here
- The panel and power station arrive in separate packages
The bundle includes a 400W panel, DELTA Pro 3600Wh power station and solar charge cable. EcoFlow notes that the power station and panel arrive in separate packages, so plan for two deliveries.
The bundle's key trade-off is practical: you get a matched EcoFlow pairing in one purchase, but still need to check the space and connection details for your intended setup. For a wider view of which solar panel is best, compare portability, connector needs and the power station's input limits together.
What does the EcoFlow panel weigh and how does it fold?
The EcoFlow panel weighs 16 kg (35.3 lb) and is foldable, with an adjustable carry case. That's useful for packing and carrying, but its weight alone doesn't tell you how easy it will be to move from a vehicle to the setup spot.
For comparison, the Renogy blanket weighs 16.09 lb and folds to 16.54 x 15.83 x 4.13 in. The Renogy suitcase panel weighs 30.2 lb and folds to 33.7 x 27.95 in, so it takes up more packed space than the blanket.

What are the EcoFlow panel's unfolded dimensions?
The unfolded dimensions aren't specified here, so don't assume the panel will fit a particular ground space, RV storage area or balcony. Ask EcoFlow for the full measurements before buying if your setup area is limited.
A panel's packed size and its open footprint answer different questions. The EcoFlow carry case and foldable design address transport, while the open dimensions matter when you lay out and angle the panel.
The best foldable solar panel 400w guide can help you compare other panels by packed size and folding style. For EcoFlow-specific alternatives, see best EcoFlow portable solar panel.
How does the EcoFlow 400W panel compare with the Renogy options?
The EcoFlow panel is the lightest option by the stated weight of the suitcase-style Renogy panel, while the Renogy blanket has the smallest published folded dimensions. Compare connection requirements and your power station's input limits before deciding based on weight or size alone.

| Panel | Weight | Folded dimensions | Connection and compatibility notes |
|---|---|---|---|
| EcoFlow 400W | 16 kg (35.3 lb) | Not specified here | Confirm compatibility and connector requirements for your setup |
| Renogy 400W suitcase | 30.2 lb | 33.7 x 27.95 in | MC4 output cables; adapter sold separately |
| Renogy 400W blanket | 16.09 lb | 16.54 x 15.83 x 4.13 in | MC4 output; adapter sold separately |
Renogy 400W Portable Solar Panel: Best for published folded dimensions
- 400W output
- 30.2 lb
- Folds to 33.7 x 27.95 in
- MC4 output cables
A folding suitcase panel for buyers who want published folded dimensions and a carry case. Check your power station's voltage, current and connector needs before buying.
Pros
- Published folded measurements
- Carry case included
- Fiberglass reinforcement and ETFE coating
Cons
- Heavier than the EcoFlow panel
- MC4 output only; adapter cable sold separately
The suitcase panel offers published folded dimensions, a carry case, fiberglass reinforcement and ETFE coating. Renogy names several compatible power stations, including EcoFlow DELTA 3 and DELTA 3 Max, but you still need to verify that your specific model's voltage, current and connector requirements match.
Renogy 400W Portable Solar Panel for Power: Best for compact storage
- 400W solar blanket
- 16.09 lb
- Folds to 16.54 x 15.83 x 4.13 in
- 16BB N-Type cells
A compact blanket-style option for travelers who want a smaller packed size and multiple placement methods. It uses MC4 output, so check the adapter and input requirements for your power station.
Pros
- Small folded size
- Lower weight than the EcoFlow panel
- Can be placed on the ground, windshield or hung
Cons
- MC4 output only; adapter sold separately
- Secure it against wind when set up outdoors
The blanket folds into a smaller package and can be laid on sunny ground, placed across a windshield or hung between trees or racks. Renogy says to secure it with tie-downs, stakes or weights in windy campsites, and its MC4 output means you may need a separate adapter for your power station.
If packed size is the deciding factor, the blanket has the smallest stated folded dimensions. If you want a suitcase format with published measurements, consider the other Renogy option.
A portable solar panel with N-Type cells is another comparison to make if cell type is part of your decision.
Does the EcoFlow 400W panel work with other power stations?
Don't assume the EcoFlow panel will work with every power station just because both use solar charging. Check the station's permitted solar input, voltage and current limits, then confirm the connector and cable match.
The data here describe the EcoFlow panel as paired with the DELTA Pro. The Renogy suitcase and blanket details name several other power-station models and specify MC4 output, but those details don't confirm compatibility for the EcoFlow panel.
For a complete portable setup, compare a best portable solar panel kit with the panel-only options. A kit may suit you if you need components together, while a standalone panel gives you more choice over the station and cables.
What charging time does EcoFlow claim?
EcoFlow says one 400W panel can recharge the DELTA Pro in 11 hours, and three 400W panels can do it in 3.5 hours. These are EcoFlow's claims for that pairing, not a promise that every day or setup will reach the same times.
Sun angle, shade, temperature, cable length and the power station's input limits can affect solar output. The Renogy panel details call out these factors as well, so leave room in your plan for changing conditions rather than relying on rated watts alone.
If you are choosing the station and panel at the same time, compare the best 400W solar panel for power station options and the best portable power station with solar panel guide. Check the station's input limits before choosing a panel based on its rated output.
Who should choose the EcoFlow bundle?
Choose the EcoFlow bundle if you want the 400W foldable panel with the DELTA Pro and its stated 15 outlets and ports. It includes five AC outlets, four USB-A ports, two USB-C ports, two DC ports, a car power output and an Anderson port.
The bundle may be less convenient if you need published panel dimensions before buying or want to mix brands. Ask EcoFlow for the open footprint and check your station's solar input and cable requirements before choosing.
What should you confirm before buying?
Confirm the panel's unfolded measurements, connector and solar input limits before you commit to a setup. Those details determine whether it will fit your available area and work with your power station.
Use this short checklist:
- Ask EcoFlow for the panel's unfolded dimensions if space is limited.
- Confirm voltage, current and connector compatibility with your exact power station.
- Decide how far you'll carry the folded panel and whether 16 kg works for that route.
- Allow for two deliveries if buying the DELTA Pro bundle.
- Compare the Renogy blanket's compact folded size if storage is tight.
The EcoFlow panel's weight and carry case make its transport details clear, but its open footprint still needs confirmation. Make that measurement part of your decision if you need to set up in a confined area.
Should you choose the EcoFlow panel or a Renogy alternative?
Choose the EcoFlow panel bundle if you want the panel paired with the DELTA Pro and can verify the open dimensions and compatibility for your setup. Choose the Renogy blanket if compact packed dimensions matter most, or the Renogy suitcase if you want a foldable format with stated measurements.
Before you decide, compare your storage space, carrying route and power station input limits. Those checks will tell you more than the 400W label alone.
Frequently asked questions
How much does the EcoFlow 400W portable solar panel weigh?
The EcoFlow 400W panel weighs 16 kg (35.3 lb) and comes with an adjustable carry case. That's heavier than the 16.09 lb Renogy blanket, but lighter than the 30.2 lb Renogy suitcase panel.
Include the case and your carrying distance in your transport plan.
What are the EcoFlow 400W solar panel dimensions?
The EcoFlow panel's unfolded dimensions aren't specified here, so you can't use these details to confirm its full setup footprint. Ask EcoFlow for the dimensions before planning around a tight campsite, balcony or vehicle storage area, and check the space needed to angle and position the panel.
Is the EcoFlow 400W panel compatible with other power stations?
Compatibility depends on the power station's input limits and the panel's connectors, so confirm both before connecting it. The Renogy options list MC4 output and name some compatible power-station families, while the EcoFlow panel details here focus on its pairing with the DELTA Pro.
How long does the EcoFlow 400W panel take to charge the DELTA Pro?
EcoFlow states that one 400W panel can recharge the DELTA Pro in 11 hours, while three 400W panels can do it in 3.5 hours. Actual solar output can vary with conditions and system limits, so treat those figures as EcoFlow's charging claims rather than a guaranteed schedule.
