Cost per Wh tells you the sticker value. But a bargain NMC unit that dies in 500 charges costs far more over its life than a LiFePO4 one that lasts 3,000. So this ranks both ways. Flip between upfront value and lifetime value, and watch the false bargains drop.

Around $0.40 to $0.60 per Wh for a LiFePO4 unit in 2026, with value brands near $0.35. But upfront $/Wh is only half the story, a battery that dies fast costs more over its life.
LiFePO4 for real value. It lasts 2,500 to 3,500+ cycles versus 500 to 800 for NMC, so it delivers 3 to 4 times more energy over its life at a similar price. NMC is lighter for ultralight travel. Switch to lifetime value to see the gap.
~300Wh for phones, laptops and camping. 1000Wh for a fridge or CPAP overnight and short outages. 2000Wh+ for home backup and tools. Filter by capacity.
For most people yes: silent, indoor safe, no fuel, solar rechargeable. A generator is cheaper per Wh for long multi day outages but loud and outdoor only.
