If you love hiking or camping, chances are you’ve brought a portable charger with you. But depending on how much you use your phone—or how long you’re out there—that charger will eventually die.
That’s where solar power banks come in. These promise you the ability to charge your phone anywhere using just the sun… basically unlimited power.
So I picked up some of the best-selling options on Amazon and put them to the test to see if they actually deliver on these promises!
If you’d like to watch the video of my testing out these solar power banks, watch here:
🔋 The Solar Power Banks Tested
A compact 10,000mAh option with:
- 20W USB-C fast charging
- Wireless charging
- Flashlight + compass
- Waterproof + shock-resistant design
This one is small and budget-friendly—but we’ll see how it performs.
This one stands out right away with:
- 4 solar panels
- 48,000mAh claimed capacity
- Built-in cables
- Multi-device charging
The goal here is faster solar charging and more versatility.
On paper, this one looks stacked:
- 49,800mAh claimed capacity
- 4 solar panels
- Built-in cables + wireless charging
- Flashlight + carabiner
Highest capacity so far—but does it actually translate to performance?
This one is in a different category:
- ~60,000mAh equivalent (192Wh)
- Up to 140W output
- Multiple ports
- Recharge via wall, car, or solar
This is the premium option… so it better perform like one.
🔌 Charging Speed Test Results
I used a USB digital tester to measure watt output and tracked battery gain after 3 minutes.
Built-In Cable Performance
| Power Bank | Watt Output | Battery Gain (3 min) |
|---|---|---|
| BLAVOR | 6-7W | +3% |
| SOARAISE | 7.19W | +3% |
| KEPSWIN | 7.12W | +3% |
| ANKER (no solar) | 16.9W | +6% |
| ANKER (with solar) | 20W | +7% |
Using My Own USB-C Cable
| Power Bank | Watt Output | Battery Gain (3 min) |
|---|---|---|
| BLAVOR | ~18W | +5% |
| SOARAISE | ~8W | +4% |
| KEPSWIN | ~18W | +7% |
🔑 Key Takeaway:
If you take ONE thing from this test:
👉 Use your own cable.
It makes a huge difference—especially for the Blavor and Kepswin.
🔋 Multi-Device Charging Test
I tested how each power bank performs when charging a phone + iPad at the same time.
| Power Bank | Single Device | With Second Device | Performance |
|---|---|---|---|
| BLAVOR | 17W | 7W | Big drop |
| SOARAISE | 7W | 6W | Slight drop |
| KEPSWIN | 7W | 7W | Holds steady |
| ANKER | 17W | 13W | Still strong |
Using My Own USB-C Cable
| Power Bank | Watt Output | Battery Gain (3 min) |
|---|---|---|
| BLAVOR | ~18W | +5% |
| SOARAISE | ~8W | +4% |
| KEPSWIN | ~18W | +7% |
🔑 Key Takeaway:
Anker is still the fastest—even when sharing power. If you’re charging a phone and tablet simultaneously, nothing here comes close.
Kepswin is the most stable which is impressive for its price point. Curious how it stacks up overall? Find out in this KEPSWIN 49800mAh review.
Blavor drops off hard under load. It is best kept for single-device use — power drops noticeably once you plug in a second device.
☀️ Solar Charging Test (2 Hours)
I left all the power banks outside under direct sunlight for 2 hours to see how much power they gain. Here’s what I found:
| Power Bank | Starting Level | Ending Level | Gain |
|---|---|---|---|
| BLAVOR | Low | ~25% (1 bar) | +1 bar |
| SOARAISE | 50% | 75% | +1 bar |
| KEPSWIN | 1 bar | 1 bar | Almost none |
| ANKER | ~60% | 100% | ~+40% |
🔑 Key Takeaway:
- 🥇 Anker dominated solar charging by a wide margin which is not surprising for the premium pick.
- 🥈 Blavor and Soaraise landed about the same. If you’d like to know more on whether the SOARAISE is worth the price over other solar power banks, check out this SOARAISE 48000mAh review.
- 🥉 Kepswin struggled the most despite having four solar panels.
🧱 Durability Test
I dropped each one to see if they could handle real-world use.
| Power Bank | Result |
|---|---|
| BLAVOR | No issues |
| SOARAISE | No issues |
| KEPSWIN | Still works (rough impact) |
| ANKER | Scratches, but fully functional |
🔑 Key Takeaway:
👉 All passed. No failures.
🏆 Final Verdict: Which One Should You Buy?
Fastest charging (by far)
Best solar performance
Handles multiple devices easily
If you want the best—and don’t mind paying for it—this is the one. I cover everything you need to know in my complete Anker SOLIX C200 buyer’s guide.
Great value for the price
Strong performance with your own cable
- Compact + durable
This is the one most people should probably get.
