Our Verdict: BLAVOR Solar Power Bank 20000mAh
A solid 20000mAh power bank first and a solar charger a distant second, since its little panel only trickles.
A pocketable battery with built-in cables, 20W USB-C, a 5W wireless pad, and a small solar panel for emergency top-ups.
So, is it any good?
By far the most pocketable item here, a single hand-sized brick.
Built-in cables mean nothing extra to carry.
The battery and 20W charging are genuinely good, but treat the solar panel as an emergency trickle, not a recharge plan.

Our Analysis, Comparisons, and Test Results
The BLAVOR Solar Power Bank 20000mAh scored 80 out of 100 overall.
It is strongest on weight & portability and weakest on multiple device charging speed.
Here is how it did on every metric we tested, with exactly how each score compares to the rest of the field.
Value for Money
Cheap and rated 4.4 stars across more than 3,600 reviews.
You get a real 20000mAh bank plus flashlight, wireless pad, and built-in cables.
The solar panel is a bonus feature, not the reason to buy it.
| Value for Money | Rating |
|---|---|
| Best in test | 9/10 |
| BLAVOR Solar Power Bank 20000mAh | 8/10 |
| Category average | 7.9/10 |
| Worst in test | 7/10 |
Charge Interruption Recovery
As a battery it stores charge, so brief sun gaps do not stop your devices charging from the bank.
The solar panel itself just resumes its slow trickle when sun returns.
Here's what that means:
Wall or USB-C charging is the sensible way to refill it.
| Charge Interruption Recovery | Rating |
|---|---|
| Best in test | 8/10 |
| BLAVOR Solar Power Bank 20000mAh | 6/10 |
| Category average | 6.1/10 |
| Worst in test | 5/10 |
Charging Speed
20W PD and QC3.0 over USB-C give real fast charging from the battery.
The 5W wireless pad is slow, best for overnight top-ups.
Solar input is a trickle, with users citing roughly 18 to 20 hours of sun to fill it from empty.
| Charging Speed | Rating |
|---|---|
| Best in test | 9/10 |
| BLAVOR Solar Power Bank 20000mAh | 7/10 |
| Category average | 7.4/10 |
| Worst in test | 6/10 |
Multiple Device Charging Speed
Built-in cables plus ports let you run a couple of devices at once off the stored charge.
Total output is shared, so speed drops with more devices.
Fine for a phone and a watch, not for fast dual-charging.
| Multiple Device Charging Speed | Rating |
|---|---|
| Best in test | 7/10 |
| BLAVOR Solar Power Bank 20000mAh | 6/10 |
| Category average | 6.4/10 |
| Worst in test | 5/10 |
Durability
Flame-retardant housing feels sturdy in reviews.
Rated IPX5, so it handles splashes but is not for immersion.
A carabiner and flashlight round out the camp-friendly build.
| Durability | Rating |
|---|---|
| Best in test | 9/10 |
| BLAVOR Solar Power Bank 20000mAh | 7/10 |
| Category average | 7.5/10 |
| Worst in test | 5/10 |
Weight & Portability
By far the most pocketable item here, a single hand-sized brick.
Built-in cables mean nothing extra to carry.
The lightest and most grab-and-go option in this lineup.
| Weight & Portability | Rating |
|---|---|
| Best in test | 10/10 |
| BLAVOR Solar Power Bank 20000mAh | 10/10 |
| Category average | 7.6/10 |
| Worst in test | 5/10 |

What Other Portable Solar Panels & Chargers Should You Consider?
Not sold on this one? A few others from our testing are worth a look.
The BigBlue 28W Foldable Solar Charger is our best solar charger with digital ammeter. The most reliable small USB solar charger here, so long as you accept it tops out near 20W of real USB output, not the 28W on the label.
The ALLPOWERS 21W Foldable Solar Panel Charger is our best foldable solar charger. A tiny, cheap 21W folder that sips power well in full sun but nearly gives up in cloud or shade.
The Jackery SolarSaga 100W Air Solar Panel is our best solar charger for camping. A genuinely light 100W panel that comes close to its rating in full sun and adds a small bifacial bonus over reflective ground.
