3-In-1 Smart Battery Charger

Needed to buy a uncomplicated battery charger for my daughter. Hook it up, plug it in and this charger figures out the rest. It has a much less intimidating look those who are less mechanically inclined also. Worked great and she was not afraid to use it...mission accomplished

Easy to understand operation. Automatic mode takes the guess work out of connecting it to your car battery. I like the display showing what my voltage and amperage is as it is charging. Works very well

Works

I needed this to force charge my car battery from 0.0 volts. It worked! Left it 20min to get a good charge and switched to auto to not over do it. I put my battery on a smart charger after just in case, but no way was anything else but manual going to bring back my battery. It's very hard to find manual chargers that do this these days and for the price it's incredible. I have a charged battery now at 13.5v. Get em while their hot.

I tried this as a recommendation from a person I consider quite knowledgeable in solar & wind technology. Indeed, this unit works great at bringing some batteries back and keeping them there. But ham radio operators beware, mine emits some horrible RFI on the HF portion of the spectrum...especially 3.600-3.999 kHz (75/80m bands). While I use it on my emergency battery back up arrangement, just thought I'd mention I cannot run it while playing radio. Given that, I'm quite sure it will interfere with SWL (short wave listeners) use as well...at least in the HF portion of the spectrum. I haven't tried it in VHF/UHF spectrum because most of that is FM & often digital use these days, I prefer SSB ops even on VHF. Digital modes like PSK don't seem to be affected much by it but if you are listening there is little to filter it out. So while I gave the unit 5 stars in value & performance, the key to that is it is horrible to run while hoping to listen to ham or shortwave radio. Users just need to know this I think. Other than that I think it's a terrific value.

I purchased this charger to charge both the 12 volt and 24 volt systems in my new boat. When hooked up to either the 12 or 24 volt system it automatically detects and displays which system it's hooked up to. It also tells the charge status of the batteries. It also then tells the amperage it is charging at which eventually goes down as the battery is being charged. When the battery is fully charged, the charger automatically goes into a maintainer mode but at that point I go ahead and unplug it, just so I don't wear out the fan, because the instructions say the fan must always be running when charging. A lot of products I've owned over the years the first thing that goes bad is the fan so I'm just trying to save the fan. The charger description said that the charger also repaired batteries, which I found out to be soooo true. My riding lawn mower battery had basically gone bad and I had to charge it every time I used it and the next day it would be dead again. I decided to try this new charger on that battery and sure enough, it seems to have rejuvenated it because it now holds a charge for several weeks. This charger actually paid for itself right away because now I don't have to purchase a new lawnmower battery this Spring which would cost more than the charger cost. The short cables don't bother me a bit either, I just put the charger on a milk crate allowing me to see all the lights so I can tell what it's doing. This product is so inexpensive I don't know how long it will last but all I have to say is I'm extremely happy with it right now.

The battery leads are way too short. AC lead is also too short. The automatic function assumes a depleted 24V is 12V and will not charge. 10A is really only a trickle charge. "User manual" is a silly useless mess of bad English that explains only the obvious. No explanation of all the panel lights or what the flashing colors mean. Low contrast display hard to read unless angle is right and no more than 20" away. Nevertheless, it will eventually charge a 12V battery. Good luck with 24V use. Should have a 12V/24V switch. Good price.

This is my second one (have the original for years & still being used ! Although people have had problems with: A) Display (unplug when not being used and never push on the actual screen B) Fan (many complain of fan). I have same problem & since replaced both units with a “60 x 60 x 25 mm double ball bearing fan. You shouldn’t have to do this but even years later the company has not made that change. Either way this “el cheapo” charger continues to work both for charging as well as trickle charging. No speed demon but like the energizer it just keeps working !

Très surprenant
