Porsche Charge-o-mat Pro Battery Maintainer and Charger

Works very well and extremely convenient to simply plug into the power socket to keep battery topped up. If your Porsche’s not a daily driver, don’t learn the hard way that it’s a pain to get the “frunk” of a modern 911 or 718 open once the battery runs down! (You have to connect 12 volt source to a point on fuse block under dash). Your battery WILL run down if car is not driven weekly. And of course the “frunk” is where the battery lives….The charger is overpriced compared to the generic model, but if you want the Porsche labeling, you pay for it. At least It does include the nice protective rubber bumper and car plugs, which is extra on base models. The only flaw is that in the event of power loss the charger does not return to “on” status after power is restored, so if you’re away for a while or don’t notice, your battery will run down even though charger is connected and plugged in. Some of the other models of this brand return to charge status when power is restored, like this one should.Unlike other reviewers, I have had good success with this brand charger lasting for years under continuous use. I have 5 of them, several over 6 years old, that are still going strong. I have not had the same success with other brands.

so far so good. charged a not-long dead battery on a Boxster within 12 hours (may have been fewer hours but left it plugged in overnight and in the morning the battery was ready to go and started right up) ... used only once so far and look forward to consistent charging when car not in use. quite compact which is good for ease of use. functional as expected.*** be sure to select which type of battery you are charging because there are three options *** (motorcycle/car/lithuim)nice long cords on both sides. plugged one cord into the "cigarette" lighter inside the car and the other cord into a regular 110 outlet. no problem.

The ability to charge and keep charged a battery through cigarette lighter is genius. Access to battery terminals in the newer Porsche requires the removal of panels to access the battery terminals. So convenient

pls don't buy tis product very unreliable battery tender unfortunately I was confident it will work since its branded I ended up calling roadside assistance to jump my car , bought another product from amazon called citek works better than porches branded product.

I have had a Porsche charger since 2008.... that one finally quit working so I bought this one for my car. It works great, simple to use and maintains the battery during the winter while the car is stored

Good as expected and advertised.Expensive vs other alternate options- however I didn’t want to gamble it and try and error other options - lost one start just because of price.

Does exactly what it says. Great unit.

Want a replacement!!! I like your Maintiner but HELP.... Dw
