Detailed overview: EcoFlow 45W USB-C portable solar panel
The EcoFlow 45W portable solar panel is the most compact model in the brand's solar range. Its 45W of rated power is split across two outputs: a built-in USB-C port, capped at 15W (5V/3A), for charging phones, tablets and electric air pumps directly in the sun; and a DC5521 connector, which delivers the full 45W to an EcoFlow RIVER series power station via the included DC5521-to-XT60i adapter cable.
Its key asset is minimal bulk: its four-fold structure measures just 222 x 309 x 40 mm when folded, barely the thickness of a book. It stows in the smallest spaces and travels effortlessly, hung on a backpack or slipped into a pocket. It is the panel to take on a hike, a trek or light travel, when every gram counts.
Despite its mini format, it makes no compromise on efficiency: thanks to TOPCon solar technology, a first in the world of mini portable solar panels, it reaches a conversion rate that can climb up to 25%, for a faster charge on a small surface. On ruggedness, its fibreglass circuit boards and durable ETFE coating, combined with IP68 certification, let it withstand harsh weather conditions.
Ultra-compact, versatile thanks to its USB-C and DC5521 outputs, and efficient, the EcoFlow 45W solar panel is for anyone who wants to charge their electronic devices or a power station directly in the sun, on a hike, camping or travelling, in the smallest possible format.

☀ How fast does this panel recharge a power station?
The EcoFlow 45W panel (45 W) recharges a Jackery Explorer 1000 v2 (1070 Wh) in ~34h or an EcoFlow Delta 2 Max (2048 Wh) in ~65h, in full sun.
| Compact / mid | Recharge |
|---|---|
| Jackery Explorer 100 Plus (99 Wh) | ~3h10 |
| EcoFlow Trail 200 DC (192 Wh) | ~6h05 |
| EcoFlow River 3 Plus (286 Wh) | ~9h05 |
| EcoFlow River 2 Pro (768 Wh) | ~24h |
| High capacity | Recharge |
|---|---|
| Anker Solix F2000 (2048 Wh) | ~65h |
| Allpowers R3500 V2 (2880 Wh) | ~91h |
| Jackery Explorer 3000 v2 (3072 Wh) | ~98h |
| Fossibot F3600 Pro (3840 Wh) | ~122h |
Estimate in full sun (ideal conditions). In practice, count on 3 to 5 hours of truly useful sunlight per day, so a full recharge may span several days depending on weather and orientation.

Comparison
At around £51 to £86, the EcoFlow 45W (USB-C) solar panel compares with mini USB-output solar panels, targeted by searches such as "portable solar charger" or "USB hiking solar panel". Here is how it sits against three references: the bigger brother EcoFlow 60W, the BigBlue 28W USB and the Anker 24W USB.
| Criterion | EcoFlow 45W (USB-C) | EcoFlow 60W (USB-C) | BigBlue 28W USB | Anker 24W USB |
|---|---|---|---|---|
| Power | 45W | 60W | 28W | 24W |
| USB-C port (device charging) | Yes, 15W max | Yes, 15W max | Yes (USB-A, 28W) | Yes (USB-A, 24W) |
| Full-power output | DC5521, 45W (cable included) | DC5521, 60W (cable included) | USB-A (same port, 28W) | USB-A (same port, 24W) |
| Efficiency | TOPCon up to 25% | TOPCon up to 25% | ≈ 22% | ≈ 22% |
| Rating | IP68 | IP68 | IPX4 | IPX4 |
| Observed price | ≈ £79 | ≈ £85 | ≈ £51 | ≈ £47 |
In short, the EcoFlow 45W panel stands out for its dual USB-C and DC5521 outputs, its TOPCon technology that pushes efficiency to 25% and its very good IP68 rating, in the most compact format. Its USB-C port stays capped at 15W, behind the BigBlue's and Anker's USB-A ports, which each deliver their full rated power; for full 45W power, notably towards an EcoFlow power station, the DC5521 connector and its included cable are the way to go. The 60W offers more power for a little more, to prefer if you charge more demanding devices, while the BigBlue and the Anker, less powerful, remain budget alternatives. To charge your gadgets in the sun in an ultra-thin mini format, the 45W is an excellent choice.

Our tester's review: Julien De Jurquet
The 45W is the newest addition to the EcoFlow solar range, and it is the one you take when every gram counts. You plug the phone straight into its USB-C output and charge in the sun, with no station: ideal on a hike, where it slips into the bag without weighing anything or taking up space, as thin as a book once folded in four. Despite its mini size, the TOPCon technology does the job, you gain charging speed compared with an entry-level solar charger, and the fibreglass construction with ETFE coating and IP68 certification make it reassuring outdoors. We hung it on the backpack for a full day of walking, and the phone stayed charged without us worrying about it. Two honest caveats: the USB-C port caps at 15W, enough for small devices only (for the full 45W towards a RIVER power station, you need the DC5521 connector and its included cable), and in overcast weather the output drops noticeably, as on any small panel. But to charge your gadgets in the sun in the smallest possible format, it is exactly what you need.

Yes, via the USB-C port, though it is capped at 15W (5V/3A): it lets you charge phones, tablets and air pumps directly in the sun, with no power station in between. For the full 45W, notably towards an EcoFlow RIVER series power station, use the DC5521 connector with the included DC5521-to-XT60i adapter cable.
Yes, it is the smallest in the range. Its four-fold structure measures just 222 x 309 x 40 mm when folded, barely the thickness of a book. Ideal on a hike when every gram counts.
TOPCon solar technology, a first on mini portable panels, reaches a conversion efficiency of up to 25%, meaning a faster charge on a small panel surface.
Yes. Its fibreglass circuit boards and durable ETFE coating, with IP68 certification, let it withstand water, dust and harsh weather conditions.
