    • Great charger with great features
Size: 30 Amp
This is a fantastic battery charger, it has great features and works very well. They have improved the On button, the old one could break, because it was hard to tell when it was on. That was the only problem I had with the first one. Yes, this charger is so good, I bought a second one. One keep as a charger in my garage and the second use as a trickle charger on a car in storage. These chargers work great at both tasks. The display will also show how the battery is taking the charge, which makes it easy to stop a dead battery that is never going charge. I also highly recommend TOPDON BT200 100-2000CCA battery tester which will read the percentage of battery life left, letting you know in advance that a battery is going to die on you. Have been stranded a few times on the side of the road due to a dead battery. I have a Honda with a 7 year old battery, rated for 8 years, the tester rated it still at 100% which means it still has years to go. Nearly 3 years in the garage during Covid is what probably extended the battery life, but otherwise I would have needlessly replace a perfectly good battery. The charger and the tester, work well together to keep your batteries working and letting you know when it is getting to be time to replace them. ... show more

    • Dewalt quality
Size: 30 Amp
Charger is all what I expected from the Dewalt brand. I have used it a few times but the best feature I like is the reconditioning of an old battery. I had one of my boat trolling batteries that would not charge up. Put it on reconditioning cycle and it took 24 hours but when it automatically turned off the battery had been reconditioned and now holds a full charge. Well worth the money. Not to large or to small. Easy to handle. Clamps are good quality. Look to get many years of service from it. ... show more

    • Most Versatile Auto Charger I Have Ever Owned
Size: 30 Amp
All the standards modes of charging with a fantastic "reconconditioning" mode that literally saves you from having to buy a new buyer as often as you always did.

    • Do yourself a favor and buy a Schumacher!!!
Size: 30 Amp
Not only does this not recognize an AGM battery (keeps kicking out about 45-60 seconds into a charge), but it also claims there's a connection issue. There are no options to select Amp rate, or even battery type. It also will NOT start a 6-cylinder engine that the battery is just low enough to not start on its own. It took out the battery (even though it wasn't long for the world anyways) meaning not even the dome light would work after 30 minutes of fighting with it to get it to work by switching between modes, checking, and rechecking the connections five or six times, and even unplugging it from both the outlet and battery all at once three times. Save yourself time, frustration, and possibly even money and just buy a Schumacher, as they know how to make a great battery charger and starter unit. I prefer Dewalt tools and was expecting this to be of their normal high-quality line, unfortunately, this is likely just cheaply made by a generic company, and colored/labeled as a Dewalt product. ... show more

    • Pros and con
Size: 30 Amp
This charger seems to be a good deal because you not only get a charger, but also a jump starter and alternator test function. The charger enclosure feels and looks like other dewalt products. in other words, it’s not flimsy thin plastics, it’s rugged. I don’t like the firmware/software design. When you press the “charge button”, the unit will start charging but doesn’t show you the charged percentage or voltage, just the rate of charge, in amps. If you want to see battery level, you have to stop the charging process and click the battery voltage button to find the charge percentage. In other words, I don’t have any insight of how much the battery is charged, while it’s charging. If you press the battery voltage button while charging, the display shows 99% charged, which is not correct. It’s displaying 99%, because of the charging process. I just don’t feel like that’s completely intuitive. Also, when I had the charger connected and watching the voltage and charge level, the charger started charging automatically after about a minute. I assumed that I pressed the charge button accidentally. To be sure, I disconnected the charger from the battery, unplugged the power cord, and the reconnected everything. Again, after watching the voltage / charge level status for about a minute, the charger started charging automatically. I don’t get it. I like the product but I might return for a different one. ... show more

    • Simple to use and effective!
Size: 30 Amp
I have had a few charger/boost jump units. This one has no batterys to fail. It will need A/C to make it run. Its not something you would carry in your car as a jump starter. But over the years I have had those and they have a shelf life. It has a few good functions and I like the alternator check feature. Would recommend for home use. It also has a battery reconditioner that I have yet to use but down the road it seems like a good idea. Good to have in the garage and keep on the shelf for just those times. ... show more

    • Smart charger worth the money.
Size: 30 Amp
It really works well and is worth the money. The charger is always in 'recond' mode for my car battery because it's wintertime and cold batteries need all the TLC they can get! A smart charger is a good investment!
