  • 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

  • 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.

  • 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

  • Didn't work, was returned
The one I received would turn on, but it never actually charged the battery across two days of trying. I charged the same battery with an older charger without issue. It appeared to read the right charge status of the battery, but it didn't ever stop saying it was charging, even when the battery was 100% (thanks to the old charger of mine). When I asked Craftsman about it and asked for help they forwarded the ticket to the specialty team - but I never heard from them. So, it didn't work, and was returned. ... show more
