SolidMax is a next-generation mobile battery that uses semi-solid battery technology to reduce the fire and explosion risks inherent in conventional lithium-ion batteries. Designed to operate reliably across temperatures from minus 10°C to plus 60°C, it undergoes rigorous safety testing including nail puncture, crushing, and overcharge scenarios. With maximum 100W output, it can charge smartphones, tablets, and laptop computers from a single device, while an active cooling fan manages heat from the higher power output.

Launched through Makuake, one of Japan's largest crowdfunding platforms, as a pre-sales campaign, SolidMax differentiates itself by making safety the central pitch. Rather than simply introducing a new gadget, the project clearly presents the problem—mobile battery fire incidents—and directly explains the technical solution. Specific safety test results, wide temperature tolerance, and high output specs provide concrete differentiation, while highlighting use cases like disaster preparedness, outdoor activities, and vehicle storage helps supporters envision the product in their own lives.

Highlights

  • Clearly identifies existing product weakness (fire risk) and proposes technical solution
  • Demonstrates credibility through specific safety test results (nail puncture, crushing, overcharge)
  • Differentiates through numerical specs: 100W output and wide temperature range (−10°C to +60°C)
  • Concrete use cases (disaster preparedness, outdoor, vehicle storage) help supporters relate to the product

Why this campaign attracts support

Editorial analysis based on publicly available information. It is not a confirmed account of why backers chose to give.

The project succeeds because it transforms a widely recognized social anxiety—mobile battery fires—into a clear problem statement, then presents semi-solid battery technology as a comprehensible solution. Rather than making abstract safety claims, it backs up credibility with tangible verification methods like nail puncture and crush tests, a best practice in tech crowdfunding. The 100W output capable of charging laptops provides real utility beyond smartphones, while specific use scenarios (disaster kits, camping, car storage) connect the product to diverse life contexts and motivations. This three-part structure—problem identification, technical validation, concrete application—creates multiple reasons for supporters to back the campaign.

A note from the editors

SolidMax exemplifies how to build trust in hardware crowdfunding by grounding safety claims in specific, verifiable tests rather than abstract promises. The model of presenting a concrete problem, backing it with technical proof points, and illustrating real-world use cases offers a template other hardware projects can follow. The active cooling fan detail and broad temperature tolerance also signal thoughtful engineering that goes beyond marketing. For backers, the leap from smartphone charging to laptop power and the practical disaster-preparedness angle make this feel like a genuinely useful upgrade rather than just another gadget.
