JMR Battery Charger for Porsche 911 Panamera Cayenne Macan Cayman 718 Boxter All Models Trickle Charger Conditioner Maintainer (No Lithium Mode)

Great product, lightweight and was easy to use. Works great with my 2008, Porsche 911 cabriolet. Easily connects to the 12v receptacle on the passenger side console. Charged the battery to 109% in a few hours. Highly recommend!

Easy setup and works great.

The charger came faster than expected. It looks great right out of the box and was easy to set up and was working immediately. Don't have any long term use data but it looks and feels like a quality product. I don't drive my car as much as I should so this is a great item to keep the battery fresh.

Took my porsche in for service and they recommend a battery change at over $900 due to being at 50% due to not running and letting sit during the winter months. Well looked up battery tenders and found this recommended by a few sources and was easy plug right into my car lighter and the wall in my garage and it went right to work.

I works great on my Porsche battery. The charging plug is tight and the cords are a little short but it works fine and is well built.

If you’re expecting a response from this vendor, don’t. I ordered the charger and tried it in my 2025 911, gives me an error code of EO2. Complained on their website, no response, complained through Amazon., was told to try again. There is no manual available online or with the product. Don’t buy.

Perfect for charging and maintaining the battery in a 2009 Porsche Boxster. Charging port adapter and alligator clamp adapters were both supplied, but using the Aux 12v charging port in the passenger footwell is easy and convenient. Well designed and manufactured smart charger with latest features, modes and battery compatibility.

I love how easy it is to use. Just plug it in your cigarette lighter and forget about it. My 1995 Porsche 993 put away for the cold Vermont winter.

الجهاز رائع جربته جدا سهل وأظهر مستوى الطاقة في البطاريه وجربت سرعة الشحن كان سريع من 60 إلى 80 بالميه خلال اقل من ٥ دقايق

J’ai pris ce produit pour faire un maintien de charge sur un véhicule pendant six mois. Il est très très bien. Je le conseille.

I was shocked when I switched on my 992 Carrera S to see the console struggle to come on, then a battery warning light came on. I managed to get it started so took if for a run. I don't use it enough so I got this charger. I removed the plastic cover to check what battery it is, it is an AGM. So, I put back the cover and plugged the charger into the 12v socket in the passenger footwell. I plugged the charger into the mains, and selected AGM. I was within 30 mins of turning off the ignition, so the socket was still operational. The charger began charging, from 11v up to 14.7, it kept switching off and back on when it got too hot, within a few hours the 70 amp/h battery was fully charged. I'm delighted. A great charger.

Good quality product which i use on my Porsche 911 Turbo. Can connect to battery directly but i prefer to connect to plug into cigarette lighter.
