    • FAR SUPERIOR THAN A "SMART"
Style: Charger
I hope these chargers stick around because it's the only "non smart" I could find to suit my needs. This charger is build solid. I appreciated on day one, when unboxing. I dropped charger off my workbench (my own dumb fault) and nothing got damaged. I personally can't stand any "smart" charger I've ever used. The last "smart" charger I bought a few years ago ended up in dumpster. I don't write many reviews but this is a superior charger and you need to get one before everything turns "smart". Writing this review 3 days after receiving and want to note the price has jumped approximately $45.00 from 5 days ago when I purchased. I'd advise ignoring some negative reviews saying "parts missing or shipping damage". We're supposed to be reviewing the product not shipping. If it arrived with missing parts from shipping damage: RETURN IT FOR A NEW ONE! ... show more

    • Worth the money
Style: Charger
It does what it is supposed to. It is easy to assembly and easy to use. As stated in other reviews, the ammeter is inop (does not work). Not a big deal to me, but it does that mean that the manufacturer is using lowest bidder suppliers for part? Time will tell. In the meantime it is working just fine in my shop. UPDATE: I am changing my rating from 4 to 5. The ammeter actually does work - once the battery starts to take a charge. ... show more

Failed with false advertising right out of the gate. Got the correct model number because I verified on the box but the specs don't match what Amazon says. Advertised at 225/50/25/10 but what came was 200/40/20/10. Will work just fine but Amazon needs to fix their information stat. UPDATE Decided to remove it from the box and found the box actually displayed the wrong specs. Unit does show 225amp on the panel. Upgraded from 2 to 4 stars now until I test it. ... show more

    • Powerful Manual "Dumb" Charger, Just What I Wanted.
Style: Charger
Definitely not everybody needs a charger this big. I went this big because I wanted a manual charger besides my smaller "smart” charger. I also wanted one with a 200+ amp, start, setting for doing some battery rejuvenating trials of old batteries (more tinkering), as I have seen done online. This charger had what I was looking for and for its size was very reasonably priced. It does everything I want a battery charger to do. Plus, it is made by a company, Schumacher Electric, that has been in the business for over 70 years so they must be doing something right. I had one of their chargers for over 30 years before something finally broke on it. Too many battery chargers, made today, are so called "smart" chargers. That is fine for people that don't understand battery charging and just want to put the charging cables on a battery and walk away. Being an "Old Guy", I am used to the old "dumb" manual battery chargers and they definitely have advantages that the new "smart" chargers don't have. As far as I know none of the "smart" chargers will charge a completely dead battery that is below 8 or 9 volts. For reference a fully charged 12-volt battery, in good shape fully charged, should measure no less than 12.6 volts. It is considered discharged or "dead" at 10.5 volts. At that voltage a "smart" charger will recognize it and will charge it. But I have had numerous instances where a battery's voltage is too low for a "smart" charger to work. No doubt people have replaced their battery because their "smart" charger wouldn't charge it and they thought the battery was bad. A lot of times all the battery needs is a little boost in voltage, to say 10 volts, so the "smart" charger can "see" it and charge it. Here is where having a "dumb", manual, charger comes into play. Hook the battery up to it first for a while, then put the "smart" charger on it if you want to walk away. Or leave it on the "dumb" charger but you will need to be around to monitor it and should really, at a minimum, have a volt meter to check the voltage. Better yet a volt meter and a battery tester. This is obviously for the "DIYer" as I realize a lot of people don't have the time or aptitude to do this. Being an old retired guy who has tinkered with cars and motorcycles since a kid. I have both the time and the aptitude and I enjoy tinkering. ... show more

    • **UPDATE 4/30/25** I PUT IT IN THE TRASH...
Style: Charger
First one I got came broken in the box, the base (plastic) was cracked and non functional to provide support for the charger. The second one I got lasted close to a year (extremely light, general use)..only used the start mode a handful of times, and 10amp for just normal charging of batteries. I went to charge a battery the other day, and it won't put out any amperage/voltage on any setting, except for the jump start/200+amp mode. Basically, it only outputs 200+amps at all times, which is nice, but won't allow for a normal steady charge or maintenance low amperage charge. I looked through the vents and saw that a capacitor has blown on the circuit board. We also use Schumacher battery chargers at my work (semi truck shop) and we are constantly replacing them. ( They are the automatic/''smart'' chargers though)..but nonetheless, they have a terrible rate of failure. We have went through 4 of them in the last few years. I should've bought another brand, but thought that since this charger is a manual charger and not a "smart" one, it wouldn't fail so soon..lol.. Based on my experience with this brand, my opinion is that I don't think that Schumacher chargers are very reliable. If you want a reliable charger that will serve you for years, THIS ONE IS NOT IT.. Also, this morning I had to jump start my pick-up (after sitting for about a month) and found the chargers timer knob does not function/turn on the charger anymore, so I had to push the truck out of my garage and out of my driveway so I could jump start it with my wife's truck. Usually you can feel a slight resistance on the knob when rotating it, but now it just free spools.... So yeah, wish it would've lasted longer than 2 years. I think I'm going to take it apart and see if I can bypass the timer and install a battery shutoff switch in its place... If not, it's going out with the trash ... show more

This product is a great way to extend your battery life. I have used this to charge batteries that have been sitting without use for several weeks. I've also had to use this when the alternator in my vehicle quit working and the battery drained. I love the timer. The construction is superb. I like to drag it on its wheels to the vehicle. The versatility to be used with different types of batteries, as well as different charging needs. ... show more
