PL2320 20-Amp Fully-Automatic Smart Charger, 6V and 12V Battery Charger, Battery Maintainer, and Stable Power Supply with Temperature Compensation

If you are installing a tune on your vehicle, this is a great option as it offers the 12v 20A power supply feature most tuners recommend when doing tune installation. I also like that the settings are quite easy to use and you have multiple amp options when charging. Doesn't have a "start" feature, which for me is perfectly fine since I have other options for that. Used on my 2020 Audit Q3 when installing a APR stage 3 IS38 turbo tune which takes a bit longer than a Stage 1 or 2 tune. Would also work great for VW given they share the same engine, etc platforms as the Audi's. Just verify the recommendations on power for the specific tune you are installing.

Been using one about 4 years in a dealership. Holds batteries around 12-14V during module programming, had it on EV 12V systems for hours without an issue even with batteries below 70% state of charge. It's not a high-end charge that'll put out 50A, but it does the job at 20A. It worked great until I dropped it and it stopped working, " note this was probably the 68724582 time I dropped it" lol. So that was completely my fault. So, I bought two more, one for home and one for work. So if you're looking for something that can maintain battery health at 20A, this charger is worth it.

Great tool. I bought this charger more for the power supply function for extended diagnostic sessions with the engine off and for light programming, even though it's not recommended for programming. Works great for maintaining the voltage up when using my scan tool with the engine off. I haven't used it for programming yet but many say it's perfectly capable of keeping up for most lite programming that doesn't require high current draws. What really impressed me was the battery charging and maintainer functions. It's fully automatic and once the battery is charged, it goes into a maintenance mode. Simple. The voltage and battery selection is easy. You can select between charge% and voltage on the readout. If the battery drops under 1V, the charger won't start charging as a safety measure but you can force a charge by pressing and holding the start button. If your battery is that depleted, it's probably better to charge on a 2amp trickle charge. There are clear status indicators that tell you when the unit is charging and when the battery is fully charged. You can select very easily between the modes power supply/charge voltage modes, amperages, and battery types. It will charge std lead acid, agm, and LiFe batteries. It will tell you if the charger detects an error or if the polarity connection is reversed via the indicator lamps. This is a smart charger and takes different strategies when charging, varying the voltage and amperage accordingly. For example, I started a charge on a dead lead acid battery. Voltage was just under 2V. The charger started charging pulsing on and off until the battery reached a certain voltage to ensure there were no issues before it went into a constant charge. There is a cooling fan that turns on/off on demand. This is a very well thought out, quality tool. Brilliant piece of equipment. Very happy with it👍

As an all in one charger/battery tender it appears to be extremely good good quality I've only had to use it to jump two vehicles so I'm not sure how the tender function is going to work but it'll charge just about any vehicle battery there is.

Easy to use. Charging light is dim and hard to see. Worked well on discharged battery. Clamps hook to back of charger, but weak design. Cord wraps around feet, again weak design. No carry handle.

5⭐️ Worked fantastic for my TCU xhp flashing. Even had a issue and this power supply hold my car battery steady at 13.2V during the almost 45min Flash process.

OK. Lets get this out of the way: I am an ASE certifed 15 cert master, a trainer, and lead diag tech/foreman of multiple shops for the past 40 years. (4 total, if you are good at what you do, you dont move much). I have owned and used chargers by Associated, Midtronics, Schumacher, Opti, Clore, and the 3 major tool companies (80% of which are subcontracted by one of the above, though some of their chargers have been unique to themselves). Lets start with what this does. Its a "Smart charger". Meaning it has various methods of checking a battery it is connected to and it self determines if and how to charge it within the parameters selected if the battery doesnt fail testing. Though it claims to have a POWER SUPPLY mode, It is NOT a power supply charger and should not be depended upon as such. If you need something to power your motorhome or maintain a charge while programming, this is not the best choice. (Sure on a ford or a GM it probably would manage, however on european cars there is significantly higher current draw during programming, some exceeding 75 amps! This charger does not make 75 amps! It makes 20 on high speed mode) That isnt a knock, it is simply a statement, dont buy this thinking you can watch TV and cook microwave popcorn while sitting in the trailer with an extension cord. It doesnt do that and may be destroyed if you force it to try. NOW, what it DOES do. It medium speed charges car batteries. I specifically tried it on a battery with a shorted single cell (Dont ask how I know this, or how youd know, call it a bad battery). What this means is this battery will hold a charge, but weakly, it may self drain (The shorted cell drains voltage from the other cells). I have previously been able to charge similar batteries to 10 or 11v using a standard non-smart charger and brute force charging, but they still dont last, they may drain in a day or a week, and they wont supply full current load when needed. This charger refused to start charging the weakened battery. If left in sulfation mode, it eventually charged to 2.5v, and always stopped there and eventually ended with an ERROR display. This is normal and correct for a smart charger, they dont like trying to charge defective tested batteries. Where that can be an annoyance is old lead-acid batteries. They develop sulfation, what amounts to deposits (Think of it like mold on bread) and it prevents them from taking in a charge. This material can be burned off with a high intensity charge and the battery can fully recover, but a smart charge will sense the battery as not taking enough current in the test phase and refuse to engage a charge (like this one did) so you cant really desulfate batteries well with a smart charger unless they are only very lightly sulfated and still taking a relatively high current load. A very few smart chargers have a "Manual mode" that is not smart. It lets you select a timed or constant charge at a voltage you select (Usually 13.5 or 14 or whatever preset number) and the charger puts that amount into the cables for the time selected. This is what we call manual or brute force charge, there is no testing, no safety shutdowns, no idea if the battery is overheating or boiling its cells. Its useful when needed, but for the most part it should only be used when needed. AGM and GEL batteries cannot withstand high amp charges for very long at all. Smart chargers know this (when the proper mode is used!) and will pulse the voltage in and pause at times to allow the battery to cool and prevent damage. This charger seems to do that, as I watched it engage and disengage every few minutes in AGM mode, it was longer and more stable in lead-acid mode. I was trying to decide which charger I would go with, the extremely highly rated Schumacher, or this one (about the same price). I chose this one because of several reviews and a few videos showing the schumacher's smart mode preventing a 0v battery from charging almost always. This again is normal, if the battery is asleep from long sitting at 0v, or badly sulfated, the smart charger shuts down. Both chargers have desulfate modes, but from the reading this one seemed to work more often down to 3-4v, the shumacher almost universally would not charge a battery that wouldnt stabilize at 5v before charging begins. I charged 2 -DEAD ZERO- volts batteries using this charger. the 3rd (a known defective but barely chargeable battery) did NOT charge and would not begin the process UNTIL I manually charged it for 45 minutes with jumper cables on my idling car. Then it came up to 10v, and the charger attempted charging finally. I let it sit in sulfation mode 3x as a test and NEVER did it command full charging until I manually charged the battery. It would sit in sulfation trickle mode several hours then end charging with error. Even though with some help it would begin charge on the same battery the next day. After charging this battery tested bad both with a conductance tester and with a load tester, but according to load, it was capable of passing a 240cca load (which means capacity of a 480cca battery). The battery was in fact a 650cca unit so it was significantly compromised. I keep it for test purposes. The high rate of 20amps on the Clore charger is what Id call adequate. Its not a speed charger, 30-50 amps are fast, but fast charging comes with its own set of issues, the best way to charge a battery is long and slow. Better for the battery. fast charging heats it, and heat shortens life. Its light weght which may be fine, but doesnt impress me. heavier probably means more metal, more heat sinks, more quality. But its not a featherweight. The Shumacher is heavier. Ive had it a week, so testing is still in progress, but so far, it is a good basic smart charger with fewer features than the competitor (Schumacher) but it seems to do what it claims pretty well. The Shumacher also claims to have a boost mode of higher amps (they use it as their desulfation mode) and a cranking mode of 50amps. 50amps cranking assist isnt much at all. If a battery is SLIGHTLY weak, say 10v charge, where it cranks slow already, that might be adequate. But starters draw 150-300 amps typically. 50a output may come in low and if it does, then the starter will demand whats missing from the battery and the charger, and the excess current draw can be destructive to a charger. Hence why jumper packs state 800-1000cca, they can deliver 200-400 amps at once, and have room to spare. At this point, Its doing what has been asked. No complaints yet, but gonna try another battery on it tomorrow, and also some current probe measurements during charge.

So far working well as advertised on my wife's Subaru battery. She drives very short distances so had to purchase a battery charger to compensate for the short drives. Also, works well charging my low voltage UPS sealed batteries.

Lo compré porque la marca es de prestigio, lamentablemente aunque le doy un uso ligero, a los 3 años de la compra, dejo de funcionar, el display se quedaba parpadeando y de ahí no pasaba. No lo recomiendo

I bought this in February 2021 as my old charger stopped working. Was sat in the box until a few days ago when I needed to charge the car as it hadn't been used for a few weeks. Switched it on after connecting it to my battery terminal and went inside the house for a gfew minutes. Luckily I came back out to check it and smoke was pouring out of the side vents. I switched it off and could hear burning noises coming from inside the box for several minutes. I then wnt to see my Amazon order to request a replacement and found there was no option, as apparently this had been shipped from the US. This could be a one off but it could have set light to my car or worse if it was charging in the house. To add insiult to injury I can't even replace it. Last time I buy electricals from Amazon

Used in a dealership setting for module programming seems to keep voltage levels up. This is a very durable charger and works fantastic. It’s very convenient that it comes with a place to store the clamps and cord.

$$ WARNING $$ - DANGEROUS to Non-USA Customers - 110V ONLY!!! NOT suitable for 220-240V use !!! This is NO reference on the listing or on the packaging that this is NOT 240V! The only clue is very small print on the underside of the charger. There is no 110v/240v selector switch. I have not seen a domestic use electrical item with single voltage input for decades, (UK construction site operations excepted). The Rest-of-the-World supplies items that are dual mains voltage, normally auto-selecting now, occasionally by a two-way slider. AMAZON USA!!! ** You NEED to correct your item listing URGENTLY stating 110v ONLY**

I used to work in a government lab where we evaluated barreries, battery chargers and battery testers. This unit was recommended to me by my co-workers that tested it after I retired and it appears to work well. Normally I'd connect a data logger to check on the charger's algorithm as I have done on other chargers in the past. Maybe one day. A good charger with all of the features for a good price.
