Tradeoffs

Supported limitations

  • Main trade-offThe compact size comes with clear limits. Its 288 Wh battery and 300 W output are designed for smaller loads rather than high-draw appliances, while the 100 W maximum solar input makes off-grid solar charging relatively modest. It also does not support expansion batteries.
