Capacity
DELTA 2 Max: +1,530 Wh (+295.1%).
This comparison targets buyers choosing between a high-capacity home backup unit and a lightweight portable option. The DELTA 2 Max delivers 2400W of running power and 2048 Wh of battery capacity, making it capable of powering 45 out of 53 devices tested. The Explorer 500, with 500W output and 518.4 Wh of capacity, handled only 20 of those same devices.
LFP battery chemistry gives the EcoFlow unit a 3000-cycle lifespan, nearly four times the Explorer 500's 800 cycles, and its expandable battery design adds long-term flexibility. Solar input tells a similar story: the DELTA 2 Max accepts up to 1000W from 19 compatible panels, while the Jackery tops out at 112.5W. The tradeoff is weight and portability.
At 13.2 lbs, the Explorer 500 is less than a third the DELTA 2 Max's 50.7 lbs, a real advantage for hikers and car campers traveling light.
