Very good quality and value.
Set it and forget it. Despite being spun off from Sears, the Craftsman branded products I have bought all seem to be well made and very reliable. This is the case for this battery charger. I use it to maintain my car battery while on vacation for months at a time. The writing on the front panel could be MUCH MUCH LARGER and MUCH MUCH BRIGHTER. ... show more

Very Pleased
I hooked this up to a Dodge Charger, which has charging posts in the engine compartment and the battery in the trunk. I used the charging posts near the engine. Other lower amp chargers would give me inaccurate results, I suppose due to the remote location of the battery and the long wires leading through the body to the battery cause some chargers/tenders to not work well. I have an old Diehard Platinum charger and it works very well at 40 amps and reads accurately, but that charger is over 20 years old, which is concerning. This charger was purchased to reduce the usage of the old one and works very well and deals with the remote battery location well at a 30 amp level, moving to maintain mode automatically as expected. A little expensive but peace of mind offsets the cost for me. ... show more

Only a 30 day return policy???
I only got 2 uses out of it, and it worked great. Then it died. No power, no lights, nothing. Left it on a battery, and the next day.. DEAD. For the money that I paid for it, I should have gotten more than 2 uses, and more than a 30 day return.. Really? 30 day return? WOW! I love Craftsman stuff, and my garage is full of Craftsman stuff, but this charger did not last. I am very dissappointed with the return on this. I would have swapped it for another one, I really liked it. But now I am stuck with a brick, thanks to a 30 day return policy. Very disappointed. ... show more

Best one I have had.
Purchased this to replace and Autozone one I had for awhile. This thing is a beast in a small package. It rejuvenated an old battery that my old one said was bad. Love this unit.

Good Craftsman battery charger, please make it in the USA NOW!
Great easy to use product! Basically a simple answer for maintaining your battery! Attach it to your battery, plug it in, and push start! Now we just have to convince them to start making them here in the United States again! Bring back my American Craftsman right now!

This piece is Godsend... plus can be run fully automatic!!!
This piece is Godsend... I have always owned simple "trickle chargers" and never really had a need for anything else. I recently traded in my '19 F-450 for a '23 F-150 Lariat Powerboost (Hybrid), and because I do almost solely, short trips, the house (engine compartment) battery, constantly runs low on charge. The electric hybrid motor clicks in frequently, leaving that battery to run everything inside the cab, because the alternater stops charging!!! If I did more highway driving, it wouldn't be an issue... this charger provides a quick, 20A boost, followed by maybe 12 minutes of 6A charge and I'm back to normal (probably once every 5 or 6 weeks). Hooks up and turns on quickly, plus it's fully automatic!!! ... show more
