GRECELL T3000 Portable Power Station

GRECELL isn't a household name, but the T3000 offers specs that make the big brands nervous. 2880Wh of LiFePO4 capacity and 3000W output for under $500 — that's roughly 3x the capacity of the Anker C1000 at a similar price. The catch is build quality and software aren't at EcoFlow or Jackery levels, and at 71.4 lbs it's essentially stationary. But for home backup on a budget, there's nothing else that delivers this much power for this little money. 3,500+ cycle LiFePO4 battery means it'll last a decade.
