The instruction suggests to disconect the battery from the car to avoid damaging electronic elements. Buy something else.
Crap. Really? Is that just a disclaimer or do most chargers no require this?

I don't want to have to disconnect the battery every few weeks to charge it.

I was about to order the Noco Genius1 but the price went up from $23.99 on Monday morning back to $33. How does this one compare?

Actually nevermind, I'll just wait for the Noco Genius to go on sale again. And I'll take my battery to Advance for them to charge it for free in the mean time.
Check the amazon warehouse. I just got the Genius 10 for $74. They have the 5 for around $50. Well worth it. It saved the battery that sat in my boat draining from last September to July.

You can find the instruction on Amazon. Regret that I didn't read it before I purchased it. Who would do that beside reading the website description?

Initially thought just a disclaimer. Then I searched for manuals of some other brands, none of I know has the similar "disclaimer". Returned and bought a genius 5.

Also, as previously mentioned in this thread, Gooloo has a fan to remove the heat, which I'm not aware of in any other brand.

Thanks. I cancelled. Hopefully the Noco Genius doesn't have the same disclaimer.


Edit: The Noco does not have the same disclaimer. I prefer to play it safe with Chinese products that can cause a fire.

I have this and kinda regret buying it honestly. It does work, but as others have pointed out, it just screams of cheapness.

The clamps are bulky and don't grab on side post batteries. The "smart" features end up being more of a PITA than a help, especially the auto-sensing capability that attempts to determine if you have a 6V/12V battery or a car/motorcycle battery.

As long as your battery remains at 7+ volts, it'll likely correctly sense that it should charge at 12V but if you drop below 7 volts, forget it. I had a battery that dropped to around 6V and the stupid auto sense would keep choosing a 6V battery and immediately say it was fully charged. I ended up having to jump the car, let it run long enough to charge off the alternator to get to around 12V, then quickly put the charger back on so it would correctly choose a 12V battery.

I will say that after doing all that, it did a good job of bringing that battery back from the dead and I got another couple months out of it before it totally died. The Repair mode took nearly 24 hours to complete and I questioned if it was working at all. I don't know what repair mode actually entails, but the manual specifically states that the charger must be "guarded for more than 15 minutes to prevent accidents". The "more than 15 minutes" statement makes no sense to me whatsoever but I'm guessing they want you to monitor the charger the entire time it's in repair mode to clear themselves of liability.

Overall, I feel like I should have just kept my $22 and put it toward a better quality charger the first time. The build quality seems like something you'd expect from Harbor Freight. At the end of the day though, it does appear to work if you can work around the smart sense mode, the cheap clamps and the short cables.

This is probably because you'll discover a miswiring or overheating within the first 15 minutes.If things are fine at the 15 minute mark, then you can probably leave it unattended.

I'd rather spend $22 to have something to get me by until the Noco Genius goes on sale if that's what you really want. Taking a battery to a store to charge it sounds like a pain in the ass, I'd rather spend the money to just plug it in. lol

I have been using it and it has been a life saver.
Yes it works and it's fine for most people
I ended up going back to my actual battery tender so I don't need an extension cord and no fan to stay running

I have this and used it on several dead batteries. Its sulfate mode bumps up the voltage to about 17v, then pauses and bumps it up again in an attempt to revive the battery plates. I used it on a large Mercedes battery and two jetski batteries and it worked.

Before using this, my car battery needed to be jumped if the car was sitting for longer than a day. And I learned that jumping your car is really bad for the battery (read somewhere it is similar to giving a CPR to a human).
Wait. So giving CPR to humans is bad for the human? 🤯

Yup. That's how it gets the power needed to charge the battery.

Yes, if that human needs it every other day. The heart will become weaker over time is what the author of that post was trying to say.
