Tips
- Most phones hold 12–19Wh. Charge from a USB port rather than the AC outlet to skip inverter losses.
- Running it from the Goal Zero Yeti 500X’s DC port instead of the AC outlet avoids inverter losses: about 35Wh more usable energy.
- The Goal Zero Yeti 500X uses NMC cells, which are lighter but rated for fewer cycles (typically 500–800) than newer LFP models.
