I'm sure based on manufacturing processes and tendencies today, each of these products are probably made in the same factory with the same bits and pieces, with each "brand" or "manufacturer" tweaking the specs a little.

With that being said, I have slowly been converting my stuff over to Noco. They seem to be a step up from the others. I have their battery maintainers and like them. And I have a couple of their jump packs and they are a higher quality compared to the other units on that web page.

I previously bought a couple of the smaller, less expensive boost packs that did ok with a low car battery that needed a boost....but a stone-cold - dead battery the boosters just didn't have enough gumption. The Noco unit was able to jump my completely stone-cold dead car battery on 2 occasions.

My only suggestion is to not leave any of the packs plugged in the the wall outlet continuously. I've heard too many horror stories of various battery packs, and then stuff like the kids' hoverboards and battery powered bicycles causing house or garage fires. Once they are fully charged, unplug them. Better yet, put the chargers on a timer or a wifi enabled outlet switch so you don't overcharge.
