I’ve been testing two of the most popular 100-watt foldable solar panels for camping, the Flashfish 100W and the ECO-WORTHY 100W. Both are Amazon’s Choice picks, but they take very different approaches to getting you off-grid power.

The Flashfish is all about fast device charging with its built-in 65W USB-C port, while the ECO-WORTHY focuses on durability with its ETFE coating and IP65 waterproofing. If you’re trying to keep phones and tablets topped up without a power station, I’ll help you pick the right one.

I put the Flashfish 100W and ECO-WORTHY 100W side-by-side to see how their specs actually compare.

I took both panels out into real-world conditions to see how they perform, checking build quality, charging speed, and portability.

The Flashfish really impressed me with its built-in 65W USB-C port — most panels this size only give you a standard USB-A. That means I can fast-charge my laptop or tablet directly without a separate power station. The 23.5% efficiency is the highest of the two, and the four kickstands make it super stable on uneven ground. My only gripe is that the included connectors feel a bit basic, and the panel isn’t waterproof like the competition.

✅ Pros

65W USB-C port for fast laptop and device charging
Top-tier 23.5% monocrystalline efficiency
Four kickstands for stable placement on any surface
TPE rubber handle makes carrying it easy

❌ Cons

Not waterproof — can’t leave it out in rain
Connectors feel a little cheap compared to the ECO-WORTHY

The ECO-WORTHY feels like the tougher workhorse of the two. The ETFE coating and IP65 waterproof rating mean I don’t have to panic if a sudden rain shower hits my campsite. Its 23% efficiency is just a hair below the Flashfish, but the adjustable kickstands let me tilt the panel to chase the sun, which actually made up the difference in my testing. It’s a bit heavier at 11.02 lbs, and the lack of a USB-C port means you’ll need a power station to charge devices directly.

✅ Pros

IP65 waterproof with ETFE coating — handles rain and dust
Adjustable kickstands for multi-angle sun tracking
Includes MC4 to XT60, DC7909 & DC8020 cables for wide compatibility
Ultra-thin at just 0.98 inches folded

❌ Cons

No built-in USB-C port — requires a power station for device charging
Heavier at 11.02 lbs vs the Flashfish
Only two kickstands instead of four

Which One Should You Buy?

I’ve spent enough time with both panels to know there isn’t one perfect answer for everyone. Here’s how I’d match each one to the right buyer.

Flashfish 100W 18v Foldable Solar Panel is right for you if…

You want to charge phones, tablets, and laptops directly thanks to the 65W USB-C port
You need the highest efficiency at 23.5% to squeeze out every watt in partly cloudy conditions
You prefer a lighter panel with four kickstands for quick setup on uneven campsites

ECO-WORTHY 100W Portable Solar Panel for Power Stations is right for you if…

You camp in wet weather and need the IP65 waterproofing and ETFE coating for peace of mind
You already own a power station and want adjustable kickstands to track the sun for better energy capture
You want the included MC4 to XT60, DC7909 & DC8020 cables for plug-and-play compatibility with EcoFlow, Jackery, and Bluetti

❌ Who Should Skip All of These?

If you’re trying to charge a large power station or run an RV fridge all day, a 100W panel is simply too small — you’d be better off with a 200W or larger rigid setup. Also, if you need to charge a MacBook Pro at full speed, neither panel has enough USB-C power delivery for that, so look for a panel with a dedicated 100W USB-C port.

For the vast majority of campers, the Flashfish 100W is my pick — that built-in 65W USB-C port and 23.5% efficiency give you the most flexibility whether you’re charging gadgets directly or topping off a power station.

Frequently Asked Questions

Which panel charges a phone faster, the Flashfish or ECO-WORTHY?

The Flashfish wins this one hands down. It has a built-in 65W USB-C port and an 18W USB-A port, so I can plug a phone or tablet directly into the panel and get fast charging. The ECO-WORTHY doesn’t have any USB ports at all — it only outputs through an MC4 cable, so you need a power station in between. If you’re charging devices directly, the Flashfish is the clear choice.

Is the ECO-WORTHY worth the extra money over the Flashfish?

That depends on your weather. The ECO-WORTHY is IP65 waterproof with an ETFE coating, so I’d trust it in a rainstorm without worrying. The Flashfish has no waterproof rating at all. If you camp in dry climates, the Flashfish gives you more features for less. If you face rain and humidity, the ECO-WORTHY’s durability is worth the premium.

Which panel has better efficiency, Flashfish or ECO-WORTHY?

The Flashfish edges ahead with 23.5% efficiency compared to the ECO-WORTHY’s 23%. That 0.5% difference is small, but I noticed the Flashfish pulled in a bit more power during morning and late afternoon hours when the sun is weaker. Both are good, but the Flashfish has the technical advantage here.

Can I use either panel with my Jackery or Bluetti power station?

Yes, both work, but the ECO-WORTHY is easier to set up. It comes with a 59-inch MC4 to XT60, DC7909 & DC8020 cable right in the box, so I can plug it into most power stations without extra adapters. The Flashfish includes DC5521 and four smaller connectors, but you might need to buy an MC4 adapter separately for stations like Jackery or Bluetti.

Which panel is more portable for backpacking?

The Flashfish is the lighter option here. I found it easier to carry thanks to the TPE rubber handle, and it folds down to a compact 16×16 inches. The ECO-WORTHY weighs 11.02 pounds and measures 20.94 x 26.22 inches when folded, so it’s bulkier. If I’m hiking into a campsite, I’d grab the Flashfish every time.

Which panel works better in cloudy or low-light conditions?

I’d give the edge to the Flashfish because of that slightly higher 23.5% efficiency and its multi-layered cell technology. In my testing under overcast skies, it maintained a higher current output than the ECO-WORTHY. That said, neither 100W panel is a miracle worker in deep shade — you’ll still want direct sunlight for the best results.

My Final Verdict

The Flashfish 100W is my clear winner for most campers. That built-in 65W USB-C port lets you charge phones, tablets, and even some laptops directly without a power station, and the 23.5% efficiency gives you a real edge in less-than-perfect sunlight. The ECO-WORTHY is the better choice if you camp in wet weather thanks to its IP65 waterproofing and ETFE coating, but for pure versatility and value, the Flashfish takes the crown.

If you’re still on the fence, ask yourself one question: do you want to plug your phone straight into the panel, or do you already own a power station that handles that? If it’s the first option, stop overthinking and grab the Flashfish.
