We may not realize that a portable solar panel’s usefulness depends as much on its packed size as its rated output. The EF ECOFLOW 45W model weighs 3.1 pounds and folds into four sections, making it easier to carry than many higher-wattage panels, but its low output can limit charging when sunlight is weak. We’ll compare its materials, mounting options, and compatibility to see where portability outweighs performance—and where it doesn’t.
Key Takeaways
- The four-panel design folds to 12.2 × 8.8 × 1.6 inches and weighs 3.1 pounds, making it easy to pack for travel.
- N-type monocrystalline cells offer up to 25% conversion efficiency, but the panel’s maximum output is limited to 45W.
- Position it flat, use the stand to tilt it, or hang it with the four grommets and included snap hooks.
- Its ETFE surface and IP68 rating support use in wet conditions, while the included cable connects to compatible EF ECOFLOW RIVER models.
- It suits portable, lighter charging needs, but charges larger power stations slowly; panels cannot be connected in series.
Foldable 45W Solar Panel
The EF ECOFLOW 45W Portable Solar Panel folds into a four-panel package measuring 12.2 × 8.8 × 1.6 inches and weighing 3.1 pounds, making it easier to pack than a rigid panel of similar output. We can fit it in a backpack, SUV, or minivan, then unfold it at camp or during travel. Its 45-watt maximum output suits compact power stations, including EF ECOFLOW RIVER models, but we can’t connect panels in series. For Solar panel efficiency, its N-type monocrystalline cells reach up to 25% conversion efficiency. These figures help us assess renewable energy basics: output depends on available sunlight and setup.
Detailed features
When we compare setup options, the EF ECOFLOW 45W offers more flexibility than a panel designed only for ground placement: we can lay it flat, tilt it with a stand, or suspend it using its four pre-cut grommets and included snap hooks. Its four-panel design folds to 12.2 × 8.8 × 1.6 inches and weighs 3.1 pounds, making it more packable than many rigid panels. N type cell efficiency reaches 25%, with 45W maximum output and 18V maximum voltage. ETFE weather protection and an IP68 rating protect the surface. A DC5521-to-XT60i cable connects it to compatible RIVER power stations; it can’t connect in series.
Pros and Cons
We’ll compare the panel’s advantages, including its 25% efficiency, 3.1-pound foldable design, and IP68 rating, with its limitations. Its 45W output suits compact power stations but provides less charging capacity than higher-wattage panels. We’ll assess how these trade-offs affect portability and practical use.
Pros
Although its 45W output limits charging speed, the EF ECOFLOW panel offers up to 25% conversion efficiency and works with RIVER-series power stations. Its N-type monocrystalline cells provide High efficiency solar cells in a compact, four-panel design. At 3.1 pounds and folded dimensions of 12.2 × 8.8 × 1.6 inches, it’s easier to pack than many larger panels. We can position it flat, tilt it with a stand, or use the four grommets and included hooks for flexible mounting options. The ETFE surface and IP68 rating also support use in wet conditions, while the included cable simplifies connection.
Cons
Despite its portability, the EF ECOFLOW 45W panel has limited output, so charging a power station can take longer than with higher-wattage panels. We may notice slow charging when powering larger-capacity units or when sunlight is weak. Its 45W maximum also limits how much energy it can deliver, and we can’t connect panels in series to increase output. Compatibility is another constraint: the included DC5521-to-XT60i cable suits supported power stations, including EF ECOFLOW RIVER models, but other devices may require different connections. Before buying, we should check our equipment’s input specifications. For frequent, faster charging, a higher-wattage panel may be more practical.
Concluding thoughts
For compact, off-grid charging, the EF ECOFLOW 45W balances portability and flexible setup, with a 3.1-pound foldable design, up to 25% conversion efficiency, and an IP68 rating. Its four-panel construction folds to 12.2 × 8.8 × 1.6 inches, while grommets and snap hooks let us hang it or position it flat or tilted. Compared with larger panels, its 45W output suits lighter charging needs, not fast replenishment or series expansion. We’d pair it with a compatible RIVER power station for camping, vehicle travel, or backup use. For these ideal use cases, long term value depends on prioritizing portability over higher output.
Frequently Asked Questions
Which Ecoflow Power Stations Are Compatible With This Solar Panel?
Power station compatibility includes EcoFlow RIVER series models. For Supported EcoFlow models, we can confirm RIVER compatibility, but the provided specifications don’t identify individual versions or confirm DELTA compatibility; check your station’s solar-input connector and limits.
Can Two Panels Be Connected in Series for Faster Charging?
No—this 45W panel can’t connect in series. Its 18V maximum voltage limits expansion; instead, we can improve charging efficiency through better panel placement in direct sunlight, though two panels won’t combine in series for faster charging.
What Cable Is Included for Connecting the Panel to a Power Station?
The included cable runs from DC5521 to XT60i, connecting the panel to compatible power stations. We recommend checking your station’s connector compatibility before charging; the package also includes four snap hooks and a user manual.
How Many Snap Hooks Come With the Panel?
We count four snap hooks in the package. Under Snap Hook Count, that’s four included; Package Contents also lists the 45W panel, charging cable, and user manual. You can use the hooks to suspend the panel.
What Is the Panel’s Model Number?
The model number is EFSOLAR45W. As we’ve just counted the four included snap hooks, we can now confirm this product identification precisely; unlike the hook count, the model code uniquely identifies the panel for ordering or support.
Conclusion
We find the EF ECOFLOW 45W Portable Solar Panel best suited to travelers who prioritize packability over charging speed. At 3.1 pounds, its four-panel design is easier to carry than larger, higher-output options, while N-type cells, an ETFE surface, and an IP68 rating support outdoor use. It offers flexible placement on the ground or hanging from a pack. But 45W limits charging, especially in weak sunlight, so we’d treat it as a compact supplement, not a primary power source.
