At a Glance
This comparison targets buyers choosing between a high-capacity home backup unit and a more portable everyday power station. The Yeti Pro 4000 delivers 3600W of running power and 3993.6 Wh of battery capacity, nearly doubling the Explorer 2000 v2's 2042 Wh and 2200W output.
That extra headroom shows in device coverage: the Yeti powers 47 out of 53 tested devices versus 45 for the Explorer. Solar input tells a similar story, with the Yeti accepting up to 3000W compared to just 400W on the Jackery.
The tradeoff is significant. At 115.7 lbs, the Yeti Pro 4000 is roughly three times the weight of the 39.5 lb Explorer, and it lacks UPS functionality, which the Explorer 2000 v2 provides with a 20ms switchover.
