Capacity
Explorer 500: +262 Wh (+102.5%).
This comparison targets buyers shopping for a compact portable power station and weighing EcoFlow's RIVER 2 against Jackery's Explorer 500. The Explorer 500 nearly doubles the usable capacity at 518.4 Wh versus 256 Wh, delivers 500W of running power (compared to 300W), and powers 20 of the 53 devices in our test suite versus 17 for the RIVER 2.
That wider device coverage and higher surge ceiling of 1000W make the Jackery a stronger pick for small appliances and mid-draw tools. The tradeoff is significant, though: the RIVER 2 uses LFP chemistry rated for 3,000 charge cycles, roughly four times the Explorer 500's 800-cycle rating, and it weighs just 7.7 lbs, nearly 5.5 lbs lighter.
It also offers 30 ms UPS switching, a feature the Explorer 500 lacks entirely. Solar charge times reflect the capacity gap: 3.3 hours for the RIVER 2 versus 6.6 hours for the Explorer 500 on similar solar input.
