The best 1 kWh power station: DELTA 3 vs Explorer 1000 v2 vs Elite 100 V2 vs C1000 Gen 2
The 1 kWh class is the sweet spot for most homes: enough for a fridge overnight, a CPAP for three nights, or Wi-Fi for two days, at around $500. All four units here are LiFePO4, rated for 4,000 cycles, and within a few pounds of each other. The real differences are output, surge, charging speed and expandability.
