The Micro USB connector has a service life of 10,000 connections and disconnections. However, many owners wear out the connector sooner or break because of poor-quality power cables. To extend the service life of the connector and make it easier to connect, magnetic-connect cables have been developed. In this article, you will learn about the features, capabilities, advantages, and disadvantages of magnetic cables.

Design features

The magnetic cable is a USB cord with interchangeable connectors at the point of connection to the mobile device. The tip of the cable is always installed in the connector of the mobile device and partially extends into the connection point. To connect the tip to the cord, a strong magnetic fastener is used that can withstand the weight of most phones. For automatic connection to the device, you just need to bring its cord to the tip at 3-4 cm.

There is a set of contacts at the connection point for charging and data transfer. The number and location of the connector pins determines the capabilities of the cable. Two pins allow only charging the mobile device. The 4-5 pins support data transfer and charging in accelerated mode.

The shape of the cable tip is usually round or rectangular, so it does not matter which side of the cord is connected. The exception is some models with five pins and a rectangular tip, which require the cord to be plugged in a certain way to transmit data.

This article describes in detail what a magnetic Micro USB type cable is. Such cables provide an easy connection on either side, as well as reduce the wear and tear of the connector of the mobile device. At the same time, such cables are not efficient when using the fast charging function. It is also often short-circuited if there is dust or moisture at the connection point.

Major disadvantages

  • There is a high probability of a short circuit if the connector is loose. Some types of cables support data transfer only when connected in a certain direction.
  • High voltage drawdowns.
  • High voltage drawdowns.

Major advantages

  • Easy to connect and disconnect the cable.
  • Minimal risk of breaking the connector of the mobile device.
  • Reduces a micro USB port wearing and tearing.
  • The connector of your mobile device won’t get clogged with dust.
  • The cable is compatible with a variety of connector types: Lightning, USB-C, and Micro USB.
  • Supports data transfer and fast charging technology.

Is magnetic charging bad for battery?

No, there is no damage to the battery if the charging cable is used correctly. It is important to avoid short circuits of all kinds. Do not allow moisture near the connector and do not connect the cable if there is moisture or debris at the connection point.

Magnetic cable capabilities

Thanks to the interchangeable tips, one cable is suitable for charging devices with different connector types: Lightning for iPhone, USB-C, and Micro USB for Android. In the case of the Micro USB port, either side of the cable is available. And because the magnetic plug is installed in the connector of the mobile accessory or smartphone, the connector does not wear out due to frequent plugging/unplugging. It is more difficult to break the pins of the connector, as overloading will cause the cord to disconnect.

It is important to avoid the use of foreign metal-type elements at the connection point. Otherwise, a short circuit will occur. A similar effect is possible if the cord does not make good contact with the tip, which often leads to the melting of the cable at the connection point.

In addition, most magnetic cables are not known for their charging efficiency. When you increase the applied power, e.g., during fast charging, the voltage decreases, resulting in poor charging efficiency.

What is faster wired or wireless charging?

Wired charging is faster. With a wired connection, the maximum transmitted power can be up to 120W, while wireless does not exceed 15W. In reality, power rarely exceeds 100W with a claimed 120W. As the battery needs to be fully discharged to achieve this power. And as the battery is charged, the current draw decreases and so does the charging power. Furthermore, some manufacturers quote exaggerated wattages of 50-100W, whereas the actual wattage may be 20-30W.


What is a magnetic Micro USB cable?

The Magnetic micro USB cable is a USB cable with a removable plug. The plug is magnetically attached to the cable during charging. The plug itself is located in the socket of the device and does not need to be permanently connected.

Are magnetic charge cables any good?

Magnetic cables have low efficiency due to high resistance at the connection point. Magnetic cables are often short-circuited if connected incorrectly.

How do you use a magnetic Micro USB?

The most suitable use is to charge different electronics with different connectors. In this case, it is sufficient to hold 1-2 cables for power transfer and fit a suitable charging plug into each device’s socket.

Can magnetic chargers damage your phone?

Yes. If the cable is not connected correctly, it can cause a short circuit. The same can happen if metal debris or moisture gets into the connection.

Are magnetic USB C cables safe?

If used with care, yes. However, there is always the possibility of a short circuit. The most common problems occur with cheap and low quality cables from unknown manufacturers.

How do you use a magnetic charging cable?

For charging different electronics with different connectors. In this case, it is sufficient to have several cables for power transfer and to fit a suitable charging plug in each device’s socket.

Which magnetic charging cable is best?

Cable with fuses and other protection mechanisms. With symmetrical connection of the plug to the cord.

Is magnetic charging faster?

No, charging is slower because of the high resistance at the connection between the plug and the cable.

Which magnetic charger is best?

A cable with protection mechanisms in the form of fuses is best. Preferably with a symmetrical connection of the plug to the cord to prevent contact shorting.

How do you get a magnetic charger off your phone?

Pull out the detachable plug using an improvised tool. Do not use excessive force to avoid damaging the plug.

How do you use a flat micro USB?

Flat micro usb is used to charge various electronics.

What is on the go cable?

This is the name of a cable with an adapter to a standard USB connector for connecting various devices. The most common ones are a mouse or a USB flash drive.

Do magnetic chargers drain battery?

No, the magnetic cable has no effect on battery consumption.

Are magnetic Chargers slower?

Charging with a magnetic cable is slower compared to conventional cables, as the connections together have a high resistance. The wireless charger with magnetic attachment is also slower to charge.

Do magnetic charging cables work with a case?

Yes, if there is enough space at the connection point to connect the wire to the plug.

Is MagSafe faster than USB-C?

No. MagSafe has a maximum charging power of 15W. A power of 20-80W can pass through the USB-C cable.

Is wireless charging bad for battery?

Wireless charging does not harm the battery. The harmful effect is caused by heating of the charger. The charging process generates excessive heat, which heats up the battery and accelerates the degradation of the power supply. It is therefore advisable to ensure that the excess heat is dissipated during the charging process.

Will a magnet damage my Samsung?

The magnet should not be placed near digital devices. There is a high risk of damaging certain data or components. Accessories with a magnet are not harmful to the device due to the low magnetic content.

How efficient are magnetic chargers?

The maximum power of a magnetic charger is usually less than 15W. Most modern phones come with a 20-25W charger.
