## Overview

The Porsche Charge-o-mat Pro is a premium OEM battery maintainer designed specifically for Porsche vehicles. It plugs into the cigarette lighter and delivers a smart 5 Amp trickle charge that prevents battery drain during long storage. Compatible with all Porsche models, it can even revive dead batteries, ensuring your car is always ready to hit the road. Its compact, durable design includes a protective rubber bumper and options for wall mounting, making it the ultimate garage essential for Porsche owners who demand reliability and convenience.

## Description

This Porsche Charge-O-Mat Pro battery maintainer is designed with your Porsche in mind. Made specifically for Porsche by C-TEK, this maintainer plugs directly into the cigarette lighter in your Porsche. Using a trickle charge, it keeps your battery from ever going dead, so once out of storage, you're ready to go. Cars without cigarette lighter will need an adapter to connect directly to the battery terminals. Unlike the original Charge-O-Mat, the new updated Pro version can charge a batter that has gone completely dead and is fully compatible with all new Porsche vehicles and systems.

Review: Nice, one flaw - 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.
Review: charged a dead battery - happy about that :) - 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.

## Features

- The new, updated Porsche Battery Maintainer, made to work with all recent and older Porsches or any car that allows charging through the cigarette lighter
- Will keep your Porsche's battery charged when not in use, a must for storing the car over extended periods of time
- Easy to use by plugging into the cigarette outlet of the car and a 12V outlet
- Can easily be mounted to the wall of your garage or left on the ground well protected with its rubber bumper
- OEM made for Porsche to keep your car's battery healthy and ready to go

## Questions & Answers

**Q: I cannot seem to find any information about what the indicators LED's mean and what an abnormal condition looks like ?**
A: There is a list of conditions in the manual that comes with the maintainer (which can also be found online if needed). General rule of thumb, make sure the car's ignition was recently on (within the last 10 - 15 minutes) before plugging in. Then plug in the maintainer and chose the proper mode using the "Mode" button. After that, close the doors and lock the car. If the maintainer is not charging at this point it could be a few things. If the battery is so low that you are getting a battery light or error, the battery needs to be charged. This can be achieved by jumping the car and running it or using the Porsche clamp accessory with this maintainer (95804490075). Once the battery is charged to normal levels, cigarette lighter operations can continue.

Another problem we frequently see is a blown fuse. Any Porsche dealer should be able to test your cigarette lighter to see if the fuse has blown. This is especially common on older model vehicles.

**Q: Will this product fit porsche panamera s e hybrid 2014?**
A: This fits all Panamera models (except Hybrid) - 2009+ so it will not work with your Porsche.

**Q: If it is the us version i am buying, does it harm the electric wiring of my european spec 991 carrera 4s?**
A: I don't think so is used by the dealer in my area on their showroom models.

**Q: Will it work in cigarette lighter on Porsche Macan 2018?**
A: I don’t think so. If the Mayan is like the 911 the cigarette lighter is off when the car is off. The 911 has an auxiliary cigarette style socket on the passenger side up under the dash on the center console. That one is always on and where I plug in the trickle charger. You should check for this socket, most  Porsches Dave one. It’s a great product

### ⭐⭐⭐⭐⭐ Quality charger that is easy to use
*by Y***3 on November 13, 2020*

The Porsche charger is perfect for my needs. I have a vehicle that requires accessing the trunk and removing panels to access the battery. Utilizing the cigarette lighter for the charging plug bypasses the cumbersome process. The Porsche charger is pricier than other chargers. However, in my opinion, the construction quality/material with the attachable rubber bumper casing and ease of use make up for the difference. The Porsche Charge-o-mat is by far better than the other battery maintainers I've purchased in the past.
