So far, you might think that the HomePower 3000 seems to be treading pretty familiar territory, and correctly so. I think the first thing that separates the HomePower 3000 from its Explorer brethren is its size and weight-to-capacity ratio. So the ZeroDrain should ensure that you can store the HomePower 3000 over the long term without worrying about deep discharge. In the end, I’m attempting to answer two questions: Is the HomePower 3000 worth upgrading from previous releases? With the HomePower 3000, however, I think Jackery has taken a big step in the right direction.
