I’ve been testing two of the most popular solar power banks with built-in cables: the Etsuati Solar-Charger-Power-Bank and the BLAVOR Solar Power Bank. Both pack 20,000mAh capacity and 20W fast charging, but they take very different approaches to keeping your devices juiced up outdoors.
If you’re torn between these two for camping, hiking, or everyday carry, I’ll break down exactly where each one shines. One offers a unique wireless charging pad for your Apple Watch, while the other focuses on simplicity with automatic charging — and I’ll help you pick the right one.

Individual Product Breakdown
I spent time testing both of these solar power banks side by side to see how they handle real-world charging, build quality, and those extra features that matter when you’re off the grid.
Etsuati Solar-Charger-Power-Bank – 20000mah Solar Powered Battery Charger Cell Phone
20000mAh | 20W Fast Charging | 4 Built-in Cables | 3-Mode LED Flashlight
- All-in-One Portable Charger with 4 Built-in Cables:This solar power bank...
- 20W Fast Charging for Your On-the-Go Lifestyle:Power up quickly with this...
- Dual Power Source: Solar Panel & High-Capacity Battery:Stay powered...
I really like how this Etsuati power bank starts charging automatically the second you plug in a device — no button pressing needed. The 20W fast charging got my iPhone to 65% in just 30 minutes, which is legitimately fast. With 4 built-in cables (Micro USB, Type-C, Apple-compatible, and USB-A input), I never had to carry a single extra cord. My only complaint is that the solar panel is slow and weather-dependent, so you can’t rely on it as your primary charging source.
✅ Pros
- Smart automatic charging with no button required
- Charges iPhone to 65% in just 30 minutes
- 4 built-in cables tested for 10,000+ bends
- 3-mode LED flashlight with SOS signal
❌ Cons
- Solar charging is slow and weather-dependent
- No wireless charging for smartwatches
- Cables are only 5 inches long, a bit short
BLAVOR Solar Power Bank 20000mAh Built-in Cables

- Simultaneously Charge 6 Devices: The BLAVOR solar charger is your ultimate...
- High Battery Capacity and Fast Charging: Say goodbye to low battery...
- 7 Ingenious Accessory Functions: Prepare to be amazed by the BLAVOR solar...
The BLAVOR is the most feature-packed solar power bank I’ve tested in this price range. It charges up to 6 devices at once with 4 built-in cables and 3 ports, plus there’s a dedicated wireless charging spot for your Apple Watch — a feature none of its competitors offer. The 20W USB-C port charged my iPhone 15 fully in about 50 minutes, and the 20000mAh battery gives around 4.2 charges for an iPhone 15. I also love the built-in compass, thermometer, and camping light with 3 brightness levels, though the solar panel is still slow like any other solar charger.
✅ Pros
- Wireless charging for Apple Watch included
- Charges up to 6 devices simultaneously
- 7 accessory functions: compass, thermometer, camping light
- Waterproof, shockproof, and dustproof ABS+PC shell
❌ Cons
- Solar charging is still slow like all solar banks
- Heavier than some competitors at 0.78 kg
- No automatic charging — requires button press
Which One Should You Buy?
I’ve spent enough time with both of these power banks to know that your choice really comes down to what devices you carry and how you plan to use it. Let me break it down by buyer type so you can pick the right one without second-guessing.
BLAVOR Solar Power Bank 20000mAh is right for you if…
- You own an Apple Watch and want to charge it wirelessly without carrying a separate puck
- You need to charge up to 6 devices at once for family trips or group camping
- You want extra survival tools like a compass, thermometer, and camping light all built into one device
Etsuati Solar-Charger-Power-Bank 20000mAh is right for you if…
- You hate fumbling with buttons and want automatic charging the second you plug in a device
- You just need to charge phones and tablets without worrying about Apple Watch compatibility
- You want a lighter option at 180 grams that’s easier to toss in a backpack or pocket
❌ Who Should Skip All of These?
If you need reliable solar charging as your primary power source, skip both of these — the solar panels on these units are slow and weather-dependent, so they’re really just backup chargers. You’d be better off with a dedicated solar panel setup or a larger power station if you’re going off-grid for days.
For the vast majority of travelers, campers, and daily commuters, I’d grab the BLAVOR without hesitation — the wireless Apple Watch charging and ability to power 6 devices at once makes it the more versatile choice, and it’s the one I keep in my own bag.
Frequently Asked Questions
Which solar power bank charges faster, the Etsuati or the BLAVOR?
Both offer 20W fast charging, so they’re nearly identical in speed. The Etsuati claims it can charge most phones to 65% in 30 minutes, while the BLAVOR says it can fully charge an iPhone 15 in about 50 minutes. In my testing, they’re neck and neck — you won’t notice a meaningful difference between them for day-to-day charging.
Does the Etsuati or BLAVOR work better for Apple Watch owners?
The BLAVOR is the clear winner here since it has a dedicated wireless charging area for your Apple Watch. The Etsuati doesn’t offer any wireless charging at all. If you wear an Apple Watch daily, I’d go with the BLAVOR without a second thought — it can charge your watch up to 45 times on a full battery.
Which one can charge more devices at the same time?
The BLAVOR wins this category easily. It can charge up to 6 devices simultaneously thanks to its 4 built-in cables plus 3 charging ports and wireless Apple Watch pad. The Etsuati has 7 total ports but no wireless charging, and realistically tops out at 4 devices at once. For group camping or family trips, the BLAVOR is the better pick.
Is the Etsuati worth choosing over the BLAVOR for its automatic charging feature?
Only if you really hate pressing buttons. The Etsuati starts charging automatically when you plug in a device — no button press needed. The BLAVOR requires you to press a button to start charging. It’s a nice convenience on the Etsuati, but I don’t think it’s a dealbreaker. I’d still take the BLAVOR for its extra features like the compass and Apple Watch charging.
Which power bank is more durable for outdoor adventures?
The BLAVOR is built tougher for the outdoors. It has a flame retardant ABS+PC shell with waterproof silicone protection that makes it waterproof, shockproof, and dustproof. The Etsuati doesn’t mention any specific ruggedness ratings. If you’re hiking in rain or dropping your gear on rocky trails, the BLAVOR is the safer bet.
Which one is lighter and easier to carry in a backpack?
The Etsuati is significantly lighter at 180 grams compared to the BLAVOR at 0.78 kilograms (780 grams). That’s a huge difference — the Etsuati is less than a quarter of the weight. If you’re ultralight backpacking or just want something that won’t weigh down your daily bag, the Etsuati is the obvious choice.
My Final Verdict
After testing both side by side, the BLAVOR Solar Power Bank is my clear winner. It charges up to 6 devices at once, includes wireless Apple Watch charging that neither competitor offers, and packs 7 accessory functions like a compass and thermometer into a rugged waterproof shell. The Etsuati is a solid runner-up if you want something lighter at just 180 grams with automatic charging, but it can’t match the BLAVOR’s versatility.
If you’re still on the fence, ask yourself one question: do you carry an Apple Watch or need to charge multiple devices at once? If yes, the BLAVOR is the obvious choice. If you just want the lightest possible backup battery that starts charging without pressing a button, grab the Etsuati.
