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 |
| Direct USB-C output | Yes | Yes | Yes (USB-A) | Yes (USB-A) |
| 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 modern USB-C output, its TOPCon technology that pushes efficiency to 25% and its very good IP68 rating, in the most compact format. 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 and limited to USB-A, 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 fiberglass 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: 45W is a top-up power reserved for USB devices, not enough to recharge a large-capacity battery, 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.
