CTEK makes the one from GM and it's good. Probably doesn't matter a whole lot which one you use.

I think most of us are using CTEK 3300 or 4300. I personally have the 4300 and it has worked flawlessly.

I have the 8 amp Fat Max from Stanley. Its $30 and it can float and fully charge the battery through the rear port @ WalMart. This unit can fully charge a dead battery unlike most regular float chargers.

I have used a Deltran "Battery Tender" for many years with good results. Not as expensive
as the others, but works as well.

I have used the Del Tran tenders for over 10 years. I still have the original one I purchased and it's still going strong. I now use them in my external garage but went with the CTEK 3300 for my Corvette. I sold the one that came with the car as it does not allow for using anything but the lighter port charger and you can't add extension cables.

CTEK 3300 was pretty reasonable and I sold my officially licensed GM version to a fellow forum member.

I have been using a harbor freight one for many years, I think I paid less than $15 for it.

My research determined that the Schumacher SP3 provided the best feature set, design, included accessories (like the 12VDC accessory adapter), and overall value, compared to all the other models I reviewed (CTEK, Deltran, Stanley, etc).

Amazon.com: Schumacher SP3 3 Amp Automatic Battery Extender / Maintainer: Automotive Amazon.com: Schumacher SP3 3 Amp Automatic Battery Extender / Maintainer: Automotive

Good Luck with your selection.

That's what I use also. Been keeping the car charged up for the 6.5 years I have owned it.

I have a $25 until I bought at Pep Boys I have been using for the last 6 years on my Vettes. No problems at all.

Deltran, CTEK and Stanley are all fine. As is Battery Minder. I've used Deltran and Battery Minder for years, mostly on my bikes, but also on cars in the summer when I'm mostly riding my bike.

I have a full time hamster running in my garage with his wheel attached to converter in trunk to charge. He is trying to unionize though, so probably will get a ctek.
