This symbol is usually engraved or embossed onto the plastic casing. Additionally, some chargers may have the letters “POS” or “P” next to the positive wire connection.
Another important indicator to look for is the position of the wires in the charger’s connector. In most chargers, the positive wire is connected to the center pin, while the negative wire is connected to the outer metal casing. Take a closer look at the connector and compare the wires’ positions to determine which one is positive.
By carefully analyzing the markings on the charger and the wire connections, you can confidently identify the positive wire. This knowledge is essential for safely and correctly connecting your charger to your devices.
Visual Indicators: Color Coding On Charger Cables
Color coding on charger cables is a common visual indicator used to determine the positive wire. This method makes it easy to identify the positive wire without the need for any additional tools.
In most charger cables, the positive wire is typically color-coded with red insulation or markings. Conversely, the negative wire is usually color-coded with black insulation or markings. This color scheme follows a universal convention, making it simple to distinguish between the positive and negative wires.
However, it’s important to note that not all charger cables follow this color coding system. Some manufacturers may use a different color scheme or no color-coding at all. In such cases, it becomes essential to consult the manufacturer’s specifications or use alternative methods to determine the positive wire.
By understanding and recognizing the color coding system, you can quickly identify the positive wire on most charger cables. This knowledge ensures a hassle-free charging experience and helps prevent any potential damage or accidents that may arise from connecting the charger incorrectly.

Inspecting Charger Connectors: Symbols and Markings
Inspecting Charger Connectors might be one of the easiest ways to identify the positive wire. Many chargers come with symbols and markings that indicate which wire is positive. These symbols can vary depending on the charger brand and model, but they are generally standardized.
One common symbol is a plus sign (+) near the positive wire. The plus sign indicates the wire’s positive polarity. Similarly, a minus sign (-) near the negative wire signifies the negative polarity.
Apart from plus and minus signs, some chargers may use other symbols like a circle with a dot inside or a dot on one side of the connector to indicate the positive wire.
When inspecting the charger connectors, ensure that you have a good source of light and a magnifying glass if needed. Take your time to carefully examine the charger connectors for these symbols and markings. If you find them, you can easily determine which wire is positive and which one is negative.
Trial And Error: Using A Multimeter To Determine Polarity
Determining the polarity of a charger wire can sometimes be a confusing task. However, one effective method to accurately identify the positive wire is by using a multimeter.
To begin, set your multimeter to the DC voltage mode. Next, insert the charger plug into an electrical outlet. Then, place the black probe on the outer metallic part of the charger plug, which usually represents the negative terminal. Proceed by touching the red probe on the exposed wires at the other end of the charger cable, one at a time, while observing the multimeter’s reading.
If the multimeter displays a positive voltage reading, it means that the particular wire being tested is the positive wire. Conversely, if the reading is negative or zero, then the wire is the negative wire. Make sure to perform this test with caution, adhering to proper electrical safety measures.
Using a multimeter eliminates the ambiguity surrounding wire polarity, providing a reliable method to differentiate between positive and negative wires on a charger.
