Review: Great little charger - This is a nice little charger, great for the price. This is simple to use, works well and afordabe. The wires are a little cheap, but for what it is, its great. I have it connected to a 12v lead acid that runs my well pump (6a 12v) and it works great. I connected it and have to do nothing now. Great purchase!
Review: Really Good Product - This little thing works great! My car battery was dead this morning. Ordered it and received it within hours same day. Only charged less than 10 minutes and car started with no problem. It's small enough to keep in my trunk just in case I need it again in the future.

## Questions & Answers

**Q: This didn't come with a owner's manual. could somone send a link of the manual to upload, or send some screenshots, to know all of the features???**
A: I've attached a video of the manual, which I have as a scanned PDF.  Why Amazon doesn't let us post a PDF is beyond me!  Anyway I converted the PDF to a video using Debut software.  
BTW... I use the charger all the time to keep my tractor, Gator, and vehicle batteries charged during winter months of inactivity.  I really like its ease of use and functionality.  Gets 5 stars from me...I have two of them, one at Ranch and one at home.

**Q: Can this charge marine batteries?**
A: Yes, will charge deep cycle 12v batteries. Select MOTORCYCLE for low amp charge or indefinite maintainer.  Or for faster charging, charge the battery in regular mode (STD/AGM,GEL/WET) and it will go through the cycle and charge to FULL. Then switch to MOTORCYCLE mode to maintain the battery for long periods. Once it finishes the motorcycle charge mode, it will indicate FULL and go into standby mode. If the battery voltage drops below FULL, the charger will restart and charge to FULL again and repeat the process, thus not overcharging the battery. I have tested this mode several times by turning on the headlights to force the battery voltage to drop while leaving the charger connected. Each time it has restarted and topped of the battery to FULL and gone back into standby. The enclosed instructions are crap. I found this information on a different branded but exact same model instruction. This Amazon website now shows these instructions.

**Q: I have a condo so I can’t run a power cord to my parking spot. Can I charge the unit then charge my battery. If not do u kno of a charger that does?**
A: No, it will not "charge" your battery. It will give you enough power so that you can start you car. The battery should charge while you drive or let it run for a while. If the car will not start after you have driven it, it's time to buy a new battery.

**Q: Do battery charger operate well off a generator ?**
A: I have never tried it with a generator, my utility supply is 115V and it works well. I think that it will work if the generator voltage is stable and at appropriate output voltage.

### ⭐⭐⭐⭐⭐ Really Good Product

### ⭐⭐⭐⭐⭐ I recommend them if you want a quick and easy to use charger!!
*by O***H on January 21, 2026*

I have purchased several of these chargers so that I can basically leave them as trickle chargers on a couple of my vehicle batteries. They are quick and easy to connect properly and do a very good job of bring your batteries up to their full potential. Understand that you cannot charge a completely dead battery. There must at least a small amount of juice left in the battery for the charger to start its programming. It's been about a year and a half since I bought my first one of these. It has continued to function very well so I'd say the quality and dependability are great with these chargers. So I recommend them if you want a quick and easy to use charger for your vehicle batteries.
