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

A really great tool to have in a shop. Had mine for about a year and it will charge/maintain any passenger cars 12v system. I’d buy another one if it ever decides to give out but it’s going strong so far. Highly recommended for the price and definitely a time saver.

I used this to maintain 14.5 volts continuous and stable power supply while I spent hours programming and coding the GM5 module, CVM module, AKMB kombi module and it was flawless. Zero fluctuations according to INPA, ISTA+P to program replacement modules and NCS Expert performance was ultra smooth when coding options. Do not use this if you are going to program or code high power parts of the car such as the ekp fuel pump control module or things that require high power motorized actuators such as water pumps or radiator fans etc… those things will need the 120AMP power supply as required by BMW technical advisors. For low powered module programming or coding with no motor actuation, this 20AMP power supply is fine. I tried using the NOCO Genius 10 battery charger/tender and it was too slow to keep up with power fluctuations by ecu requests and I could see the voltage fluctuations in the diagnostics display. But this unit was rock solid for hours…almost a full day of uninterrupted power supply. You can’t beat the price for what most diy folks will need for module flashing. I did not flash any ecu/dme with this since that may be VERY systems intensive and may require the ecu/dme to actuate lots of high power components and this may not be enough for such a situation.

Works well! What else do u need to know. I charged two car batteries this weekend from low and not enough amps to operate my remote locks. First…took at two week trip to Miami Beach and somehow left my car home with the parking lights on for 5 days…drained my battery…dead…dead. Charged battery @ 10 amps for 8 hours…all is well. Note: I did check the charging Amperage at 10 amps with my DC amp clamp…which indicated 10.08 amps delivered. Two thumbs up. 2nd car was a 2007 BMW 530i with a dead 850 CCA lead acid battery due to a loose positive terminal. Let it charge overnight…worked fine in the morning. I like mine…and I think you’ll be happy with one too. Recommended.

One of the best chargers I have used. The ability to select the battery voltage, type, and charging current means that this product is very versatile - and the temperature compensation feature means that the product will not undercharge in the winter and overcharge in the summer. I really wanted to give this product 5 stars, BUT there are some minor things that I don't like (I wouldn't call them flaws, so much as I would call them things that I wish were different). 1) The voltage/percent charge display selector switch is very close to the on/off switch. With gloves on (or if not paying close attention), it is easy to hit the on/off switch accidentally when trying to hit the voltage/percent charge switch. I made that mistake once (oops.) 2) The power cord; while it is a very robust ~14ga, 3-conductor cord, not a 'low temperature' design, so it is very inflexible when it is cold outside. They could improve this product by using a low temperature power cord. It would add a bit to the cost, but it would be well worth it. 3) The instruction manual is not well written (though I wouldn't go so far as to say it is poorly written). It simply does not provide enough detail about the function of the charger, so it left me confused when the charger was functioning in a manner that I did not expect. A couple of emails to the manufacturer's customer service department cleared things up within a couple of days, but if the manual provided more detail things would have been more clear from the start. A couple other notes about this product: - The temperature compensation feature is a very important feature for a car battery charger. This feature certainly works on this charger, though it does not seem to compensate as aggressively as some other brands (like Battery Minder). - In my opinion, this product is much better as a charger than a maintainer. If you're looking for a great maintainer there are comparably priced units that will do a better job. On the other hand, if you're looking for a great 20A lead acid battery charger, the PL2320 is better than most this price range - you probably won't find a better unit under $200.

So far so good. Quick & easy to setup when doing programming. Small and light making transporting convenient. Also able to revive older, dead batteries. Or to maintain batteries on stored cars. Waaaaay quicker than using the shop required midtronics DCA machine that takes forever to boot up AND asks 20 questions before it starts throwing the power supply. Nevermind if someone else is hogging it. I might buy another to keep one at home. Best price here. Coworker bought the mac rebrand for double the price here.

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

It is a great little unit, unable to fault. Exactly what we needed for motorcycle reflashes & battery charging

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**
