I thought this would make a good addition to the EGO tools that I have accumulated, especially since I have several batteries. I should have done better research but the lack of pass through charging was a total surprise. Pass through charging is a must for my purposes meaning that I now have a $900 four position very slow battery charger that takes up a lot of space. For the price I was also surprised that it has not 12VDC support and it does not come with solar capabilities. That requires an extra adapter.There does seem to be quality in the build and I really liked the idea of not having hundreds of dollars in batteries sitting idle most of the time. My EGO mower, chainsaw, trimmer, edger, hedge trimmer, pole saw and blower all work great. I was anxious to get the Nexus Portable Power Station due to my experience with other EGO tools over the past eight years. But I find the lack of features that are readily available on other solar generators in the price range, very disappointing.
