The Allpowers SP039 portable solar panel is a powerhouse designed for adventurers seeking reliable off-grid power. This 600W panel, comprised of six individual units, delivers impressive performance, consistently exceeding the output of comparable 350W panels. Its high voltage (52.8V VOC) necessitates careful compatibility checks with your power station, but when paired correctly, it provides rapid charging capabilities. The review details a real-world test charging a 2073Wh power station in under 2.5 hours under optimal conditions.Despite its high power output, the SP039 remains remarkably portable and easy to use, weighing only 12kg and featuring a foldable design with integrated handles and straps. The package includes essential accessories like MC4 to XT60 adapter cables and an extension cable for flexible setup. This review thoroughly assesses the panel's performance, compatibility considerations, and overall value, providing crucial information for potential buyers considering its investment.
Pros And Cons
- High power output (over 450W in good conditions, almost 400W even when flat on the ground)
- Easy to set up and take down (one-handed operation possible)
- Portable (weighs 12kg)
- Good temperature resistance (power doesn't drop significantly when heated)
- Can be used flat on the ground
- Relatively inexpensive compared to similar panels of lower wattage
- Large size (may not be suitable for small spaces)
- Requires a power station with sufficient voltage input (may not be compatible with all power stations)
- Included extension cable may not be suitable for long-term use due to lower quality

Power and Voltage Specifications
The Allpowers SP039 boasts a theoretical maximum power output of 600W, achieved through six individual panels. Crucially, its Open Circuit Voltage (VOC) is 52.8V. This is a vital consideration when pairing it with a power station, ensuring compatibility and preventing damage. Understanding the VOC helps avoid exceeding your power station's input voltage limits.
It's important to check your power station's maximum solar input voltage before connecting. Exceeding the voltage limit, even slightly, can severely damage your power station's solar controller. The SP039's maximum open-circuit current is 15 amps, with a working current of 13.63 amps. This amperage, while potentially high, will be regulated by your power station's current limit.
Compatibility with Power Stations
The SP039's high voltage necessitates careful compatibility checks with your power station. My Blueetti EB200 (60V, 20A max input) provided sufficient headroom (8V margin) for safe use. However, power stations with lower voltage limits (e.g., 28V, 32V, 48V) are incompatible and risk damage.
Even if your power station has a high enough voltage rating, the amperage is also critical. If your power station's amperage limit is lower than the SP039's output (13.63A), the excess current will simply be wasted, not harming your equipment but reducing overall power output.
Unboxing and Accessories
The Allpowers SP039 package includes a microfiber cleaning cloth, sturdy straps for securing the panel, MC4 to XT60 adapter cables, and silica gel packets to maintain dryness. It also comes with instruction manuals and an additional MC4 extension cable.
The included MC4 cables allow for flexible configuration. An XT60 connector is recommended for connecting to many power stations. The included extension cables increase the distance between the panel and your power station for safer placement.
Performance Testing and Results
Under optimal sunny conditions, with a slightly inclined placement, the SP039 consistently delivered between 440-450W. This solid performance charged my 2073Wh Blueetti EB200 from 46% to 100% in approximately 2.5 hours.
A second test with the panel lying flat on the ground still yielded an impressive 399-400W. While less than the optimal output, this demonstrates the panel's impressive power generation even in less-than-ideal conditions.
Portability and Ease of Use
The Allpowers SP039's lightweight design (12kg) and foldable nature make it highly portable. The ease of setup and takedown is a significant advantage, particularly for camping or outdoor use.
Its low profile allows for discreet placement, even in crowded camping areas. The integrated handles and straps ensure secure transport and prevent accidental damage or loss.
Overall Conclusion and Recommendation
The Allpowers SP039 is a powerful and convenient portable solar panel, excelling in ease of use and portability, making it ideal for camping and outdoor adventures. The high power output consistently exceeds that of comparable 350W panels, even in less-than-ideal orientations.
While its high price point is a factor, the performance and convenience justify the cost for those who prioritize ease of use and high power generation. Its robust build and excellent temperature resistance contribute to its overall value. I strongly recommend it for campers and those with ample outdoor space for optimal placement.
