Who it's for: hikers who want 25W and IP68 in the lightest pocket-size form. Who should skip it: anyone who wants a longer warranty or stated folded dimensions.

BigBlue 21W SolarPowa 20
A foldable 21W monocrystalline panel with dual USB output, an IP68 rating and a 2-year warranty, at 1.32 lbs.
Pros
- 21W monocrystalline panel with up to 24.7% conversion stated
- Dual USB ports at 5V, each 5V/3A max
- 1.32 lbs, the lightest stated weight here
- 2-year warranty stated
Cons
- Panel does not store electricity
- IP68 rating does not cover the USB junction box
- No folded dimensions stated, only book size
- 21W, below the 30W panels here
Detailed Review
The listing states a foldable 21W monocrystalline panel with up to 24.7% conversion, up to 95% light transmittance and a PVDF surface stated at twice the lifespan of conventional PET panels. Dual USB ports run at 5V, each 5V/3A max with a combined 5V/4.2A max, and an intelligent IC chip safeguards against overcurrent and short circuits. The panel weighs 1.32 lbs, folds to the size of a book, includes a USB-C to USB-C cable, 2 carabiners and a manual, and carries a 2-year warranty. One wrinkle: the spec table omits the manual that the bullets list, so the bullets win for box contents. The panel does not store electricity, and the IP68 rating does not cover the USB junction box.
Who it's for: backpackers who want the lightest stated weight with a stated warranty and dual USB output. Who should skip it: backpackers who want more watts than 21W or a stated folded size.

Ecosonique 30W ED-30
A foldable 30W ETFE monocrystalline panel with a smart display, dual USB output and an IP67 rating, at 1.7 lb.
Pros
- 30W, the highest watts among the full-data panels
- Smart display showing power, voltage and current
- Shade-tolerant parallel circuits stated
- Dual USB-A and USB-C output at 5V
Cons
- No warranty term stated
- Panel does not store electricity
- 1.7 lb, heavier than the BigBlue panel
- Folded size stated two ways across the listing
Detailed Review
The listing states a foldable 30W ETFE monocrystalline panel with 23.5% cells, a built-in digital display showing power, voltage and current in real time, and independent parallel circuits that let unobstructed sections keep generating power under partial shade. Dual USB-A and USB-C output charges two compatible 5V devices at the same time, the protected ports help limit dust and splash exposure, and short circuit protection is listed. The panel weighs 1.7 lb folded, includes 2 carabiners and a manual, and cannot store electricity. One wrinkle: the spec table gives dimensions of 12 by 1 by 8.3 inches while the bullets give a folded size of 11.98 by 8.27 inches, so the bullets win for folded size. No warranty term is stated.
Who it's for: backpackers who want the most watts plus a live display and shade tolerance. Who should skip it: backpackers who want a stated warranty term or a lighter panel than 1.7 lb.

How we scored them
The Solar Score weighs performance, build, value, safety and warranty. For a backpacking panel, safety means a stated weather rating and listed protections such as short circuit safeguards. Each panel here states an IP rating, and a warranty term is stated for the BigBlue panel. How we pick explains the weights.
| Product | Solar Score | Perf. /35 | Build /25 | Value /25 | Safety /10 | Warranty /5 |
|---|---|---|---|---|---|---|
| BigBlue 21W SolarPowa 20 | 9.6 | 29 | 21 | 20 | 8 | 3 |
| Ecosonique 30W ED-30 | 9.6 | 32 | 21 | 21 | 7 | 0 |
Scores run from 9.2 to 9.8: each product’s point total is placed on that range, so more points always means a higher score.
How to choose the best solar panel for backpacking under 60
Watts and weight
Watts set the ceiling for what a panel can feed, and weight decides whether it stays in the pack. The Ecosonique panel lists 30W against 21W on the BigBlue panel, while the BigBlue panel lists 1.32 lbs against 1.7 lb on the Ecosonique panel. The MARBERO panel lists 30W and the ELECAENTA panel lists 25W in their titles, with no weight stated for either. A backpacker chasing watts should look at the 30W panels; a backpacker counting grams should look at the 1.32 lbs BigBlue panel.
USB output and the devices it feeds
Output decides what can plug in at camp. The BigBlue panel lists dual USB ports, each 5V/3A max with a combined 5V/4.2A max, and the Ecosonique panel lists dual USB-A and USB-C output for two compatible 5V devices at the same time. The ELECAENTA title lists USB-C and USB-A ports, and the MARBERO title lists USB-C PD. Neither full-data panel stores electricity, so the panel charges devices while the sun hits it, and a power bank holds the charge for later. See best portable solar panel for phone for phone-first options.
Weather rating and what it covers
Weather ratings differ across the panels, and the fine print matters. The BigBlue panel lists an IP68 rating, with the listing noting that the rating does not cover the USB junction box. The Ecosonique panel lists an IP67 rating with protected ports, the MARBERO title lists an IP65 rating, and the ELECAENTA title lists an IP68 rating. Compare the stated rating, not the marketing around it, and keep the junction box in mind on wet days.
| Panel | Watts | Output | Weather rating |
|---|---|---|---|
| BigBlue SolarPowa 20 | 21W | USB-A + USB-C, 5V | IP68 rating |
| Ecosonique ED-30 | 30W | USB-A + USB-C, 5V | IP67 rating |
| MARBERO panel | 30W | USB-C PD | IP65 rating |
| ELECAENTA panel | 25W | USB-C + USB-A | IP68 rating |
Folded size and packability
Folded size decides where a panel rides. The Ecosonique panel folds to 11.98 by 8.27 inches, and the listing describes it as packing easily for backpacking, hiking, cycling and travel. The BigBlue panel folds to the size of a book, with no folded dimensions stated, and the listing includes hooks for attaching it to a backpack or tent. The Ecosonique listing also includes 2 carabiners, and the BigBlue listing includes 2 carabiners and a USB-C to USB-C cable. For larger portable options, see best 60W portable solar panel with USB-C and best portable power station with solar panels for camping.
Sizing Notes
- Match panel watts to the device input: the BigBlue panel lists dual USB ports at 5V, and the Ecosonique panel lists dual 5V output.
- Match the folded size to the pack: the Ecosonique panel folds to 11.98 by 8.27 inches, while the BigBlue panel folds to the size of a book.
- Match the weather protection to the trip: IP68, IP67 and IP65 codes are stated across the panels, and the BigBlue IP68 code does not cover the USB junction box.
- Plan for sun dependence: actual output varies with sunlight, angle, temperature and weather, per the listings.
- Check the warranty term: a 2-year warranty is stated for the BigBlue panel, and no warranty term is stated for the other panels.
Frequently Asked Questions
Can a backpacking solar panel charge a phone directly?
Yes, through USB: the BigBlue panel lists dual USB ports at 5V, and the Ecosonique panel lists dual USB-A and USB-C output for 5V devices. The panel charges while the sun hits it, since neither panel stores electricity.
Do these panels store power for later?
No. The BigBlue and Ecosonique listings both state that the panels cannot store electricity, so a power bank is needed to hold a charge for later use.
What does an IP rating mean on these panels?
It is the listing’s stated weather-resistance figure: IP68 on the BigBlue and ELECAENTA panels, IP67 on the Ecosonique panel and IP65 on the MARBERO panel. The BigBlue listing notes that its IP68 rating does not cover the USB junction box.
Which panel is lightest?
Of the panels that state a weight, the BigBlue panel is lightest at 1.32 lbs, against 1.7 lb for the Ecosonique panel. The MARBERO and ELECAENTA titles state no weight.
Do these panels work in shade?
Only the Ecosonique listing states shade tolerance: independent parallel circuits let unobstructed sections keep generating power when partial shade covers the panel. No shade claim is stated for the other panels.
What comes in the box?
The BigBlue listing includes the panel, a USB-C to USB-C cable, 2 carabiners and a manual. The Ecosonique listing includes the panel, 2 carabiners and a manual.
