What matters most when comparing power stations?
Four specs decide 90% of use cases: continuous output (can it run your loads), surge (can it start your largest motor), capacity in Wh (how long), and 240V availability (well pumps, dryers). Cycle life and recharge speed break ties.
What does $/kWh mean in this table?
MSRP divided by storage capacity — the cleanest cross-brand value metric. Installed batteries win on $/kWh but add $2,000-5,000 of installation; portables win on flexibility.
Why is every unit here LFP chemistry?
LiFePO4 (LFP) delivers 3,000-6,000 charge cycles vs ~800 for older NMC packs, with far better thermal safety. Every serious 2025-2026 home backup unit made the switch — we exclude NMC stragglers.
