3.4 Unmet Needs & Market Gaps

• Actual Output Stability: User feedback indicates actual output power is often lower than the rated value and easily affected by shadows or angles, causing charging interruptions.
  

  I could only get a maximum of 23w (and that was holding the panel at a 90degree angle to the sun. // I was never able to get the USB charging at full wattage makes me skeptical about this product.

• USB-C PD Compatibility & Stability: Some users report unstable USB-C PD charging or failure to achieve expected fast-charging effects with high-power devices.
  

  Usb-c charging unstable. // Due to USB-C being able to negotiate the voltage it wants to charge at it will pick a high voltage which gets very low amps and will be very unstable (it will constantly stop and start charging).

• Better Low-light Performance: Although some products claim cloudy day usability, users generally still believe 'full sun' is needed for effective charging, expecting better performance in low-light conditions.
  

  It charges very slow. Takes hours to charge a cell phone. // Only produced 5W out of the advertised 60W they claim in certain places.

• Integrated Energy Storage Function: Most products lack a battery, requiring users to carry an extra power bank. Integrating a small buffer battery could enhance convenience.
  

  The 30W solar panel does not store electricity and requires connection to a device, power station, or solar generator. // There is no energy storage so you can only use it while it's in the sun.

• Longer Output Cables: Users report included cables are too short, preventing devices (like phones) from being placed in the shade of the panel, leading to overheating.
  

  The cord was a bit short, so I boosted the unit upwards using an old, yet stable, typing table. // I wish the included cable was just a foot or two longer.

VI. Market Fit Analysis

6.1 Alignment Analysis

6.2 Key Findings

• Sellers' promotion of 'high conversion efficiency' and 'fast charging' is severely disconnected from user actual experience, leading to widespread complaints about insufficient actual power and slow charging. This directly damages user satisfaction and product reputation. If actual needs are not met, users may switch to other brands, higher-wattage products, or even initiate returns.
• USB-C PD, as the modern mainstream fast-charge standard, its actual stability and compatibility on portable solar panels remain a user pain point. Unstable charging or failure to leverage PD fast charging advantages damages product credibility among high-end device users, limits potential market, and may lead users to purchase additional charging solutions.
• There is a contradiction between lightweight design and structural durability; some products sacrifice the durability of key components for portability. This may cause products to fail prematurely in outdoor scenarios, raising user concerns about quality and leading to negative reviews, harming brand image.
• Usability design details for outdoor scenarios (e.g., built-in stands, longer cables, shaded device placement) are key to enhancing user experience but are often overlooked. The absence of these details adds hassle to user operation outdoors, reducing convenience. Even with good core functionality, overall ratings may suffer.
