In our controlled environment, the Jackery Explorer 240D Power Bank delivered stable and reliable performance for its compact class. It achieved ~95.8% usable capacity efficiency at 25°C, closely matching expected output for an 80,000mAh LiFePO₄ system. Using a 100W solar input, the unit recharged from 0% to 80% in approximately 2.1 hours, making it practical for light outdoor and emergency use.
*Estimated runtimes based on 1070Wh capacity (factoring in an average 85% inverter efficiency).
* Calculated using lab‑measured usable capacity (~85% efficiency) and typical load profiles. Actual results may vary.
