Portable Power Station Buying Guide
Watt-Hours (Wh) is what matters. A 1,024Wh station runs a 50W CPAP for ~17 hours or charges a phone ~60 times. Ignore "mAh" — meaningless without voltage.
Continuous vs Surge Power: Your fridge draws 150W running but 900W at startup. A 500W-continuous station trips protection even if "running wattage" is fine. BP240B (2,000W continuous) handles most household appliances.
LiFePO4 is the only right answer: 3,500+ cycles vs 500–800 for NMC. Safe indoors. UN38.3 air-certified. All AGAIC BP series use LiFePO4.
