This is a good charger, but it doesn't have the standard SAE pigtail connector that every other automotive charger uses, which is inconvenient if you use it for multiple vehicles.
I have this and it's a good unit for maintaining all batteries and for charging small batteries.

One thing I don't like about it is that it is "wall wart" style (you can see in some of the photos). So it's not always convenient to plug it in. Like if you want to use it with an outlet with a weatherproof (snap-open) cover, it probably won't fit, so you'll need to use a small extension cord anyway to go between the outlet and charger.
It's not "junk," it's typical of "smart" battery chargers/maintainers that want to make sure it's hooked-up correctly. This is a few years old and most "smart" products of that era would do that.

If you look at some of the new NOCO Genius battery systems, they advertise "works down to 1v" and even has a "Force mode" you can you use in that case where something is really really dead (though if it got that dead you may not be able to get much life out of that battery anyway). So yeah, this $20 model from a few years ago is for maintaining mostly-charged batteries, but I don't think it's "junk."

EDIT according to the description, this one DOES have the new "Force mode" also. So the "junk" post is even more wrong....

I bought a battery tender jr 4 bank charger like 7 years ago, and it's absolutely phenomenal. I dont think ive had a battery die since I got it.

I have a little single charger that if I need to take to a friends house or something, and I even have a solar powered battery tender charge controller on my riding mower in shed lol. its been going a few years now without fail.

I think battery tender > noco, I had noco, seems excessively bulky and I hate that it doesnt use the sae connections, made me buy a dongle to use with my other appliances.

just stick with battery tender jr guys. it works just fine

This thing has saved my butt a few times after the kids have hit the dome light switch and drained the battery. Takes forever to charge though.

that's a good thing...slow charging is much better for the battery.

I take the noco charger and cut the plug off when I buy them and solder on the SAE.

An occasional fast charge helps stir the electrolyte and prevent stratification and its associated issues.

Same. But I just cut, twist, heat shrink it. Takes a minute to do.

I use the Foval Automatic Trickle Battery Charger . I connect it to the cigarette lighter inside the car. Works fine. You got to have the type of lighter that works with the ignition off.
