Porsche Charge-o-mat Pro Battery Maintainer and Charger

I bought this charger 9 months ago for use charging the battery in my Porsche 911. I have used it twice since my purchase and now it is not charging at all. When it’s plugged in the green power light flashes but never changes to a solid light showing it’s charging. I even replaced the fuse in the charger thinking that might be the problem but same result. I bought this charger even though it was more expensive than other chargers thinking it would be a quality product but I regret that decision. I have tried to contact Porsche aftermarket without success. Update: I have been able to get the charger working. After calling my local Porsche dealer and getting the tip to start my car and hooking up the charger within a couple of minutes after turning off the ignition. The power light stayed solid and began working. I had no idea that starting the car just before charging would have any effect but it apparently does.

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.

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.

Works great on my 2018 911

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.

I don’t think much of it. I am frequently out of town for a few weeks at a time. So I need a charger to keep the battery up. Problem is , I live in an area where the power goes out often. Even a short power interruption shuts the charger off. It has to be reprogramed. I am not home to do that ….so…dead battery. Should automaticall return to previous setting when power is restored. I have other chargers on other batteries that reset without a problem. Not recomended

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

I bought this charger last march it was in good packing . I open the pack 2 days ago Unfortunately when I open it the device look like a returned ( used ) and more surprise it’s burned not working at all
