Amazon has the BLUETTI Elite 300 Portable Power Station for $999.99 as a Prime-exclusive Big Deal, down 33% from the $1,499 list price. That works out to about $0.33 per watt-hour for its 3,014.4Wh capacity.

This LiFePO4 unit puts out 2,400W continuous (4,800W surge) and comes with a TT-30 RV port and a 12V/30A DC output, so it’s a good fit for RVs, camper vans and home backup. Frost & Sullivan recognizes it as the world’s smallest 3kWh portable power station: it measures 14.4 x 12 x 11.7 inches and weighs 58 lbs.
