    Whether you need to charge a smartphone, laptop, tablet or other device, a broken charger can be frustrating and inconvenient. Without the need for an electrician’s certificate, there are several things you can look at to fix the problem.

    There are some basic reasons why the charger stops working:

    While some fixes may require some switching, there are many fixes that you can try to get your broken charger working again.

  1. Make sure the outlet is turned on. Some European stores have individual switches. American homes can use alternating surge protectors, a light switch that controls wall outlets, or a switch. You may need to reset a trigger.

  2. Make sure the cables are connected properly. Disconnect all cables in the system, wait a few minutes, and then reconnect the cables carefully and securely. When replacing, confirm that all connections are tight and correct.

  3. Look for light. Is the status light on if you are working with a broken Mac charger? The same goes for status lights in laptops and portable chargers.

  4. Restart the charger. The device controls a large part of the charging behavior, so restarting the device helps to detect charging problems.

  5. Try another outlet. Outlets are robust but can fail. To confirm that a socket works, check out our multimeter tips below.

  6. Check if the charger is damaged. If you see a bare wire, stripped insulation or wire shielding, it could be the source of the problem. Also connect the cable and then twist the cable at both ends. If the charger operates intermittently when you move the cable, the copper cable of the cable is damaged. If possible, replace the cable with a new one.

    Do not attempt to twist the cable at both ends if there are bare or damaged wires. This may result in an electric shock.

  7. Check the components. Remove the adapter, socket divider, electrical outlet or surge protector and any additional components so that only the charger is connected to an outlet that is known to operate. If the socket works but the charger is not activated, the problem is not in the wall socket.

    If the charger works when connected to the wall, the problem lies in one of the removed components. Replace the other parts one by one until the system fails, but do not stop there. Try adding the pieces in a different order or location.

  8. Check the fuses. When opening the fuse box, look for a reversing switch and fold it back. The gears in a column or row usually point in the same direction. If you see a fuse with the handle pointing in the other direction, it has probably tripped. Find the fuse that is connected to the socket you are using and reset it. It reappears in place with a suspension sound.

    In countries that follow the American model, a fuse box contains fuses that each control part of the household’s electrical outlets. In other countries, the fuse is built into the wall socket. When working with electricity in an unknown country, check the details before making any electrical repairs.

  9. Clean the charging port. If you do not feel a click when the charging cable is connected, look inside the charging unit. With both Lightning and USB-C charging ports, users have found that everything from pocket fluff to rice grains caught in the harbor can prevent the phone from charging. Remove any debris with plastic tweezers, a cotton swab or a toothpick.

    Never insert metal into the charging port. If you insert a piece of metal into the charging port incorrectly, you may short circuit the connection and damage the device.

  10. Try another cable and power adapter. The biggest culprit for charging faults is the fault of the charging cable. The cable takes the most stress over time, so it tends to fail first. The charging stone that connects the cable to the wall can also fail, but it is not as common. Use another USB charging cable and adapter and see if the problem resolves itself. Replace one at a time to find the culprit.

  11. Clear the USB port. If a USB port is physically prevented from making good contact by shielding, cable design, port furniture or anything else, removing that barrier can solve the problem. It is easy to bend the sheet metal cover on a USB port in shape if it has deformed over time. With modern USB Micro and USB-C devices, bend the small tongue inside the charging port if it is not in place.

    To avoid electric shock, make sure the device is turned off before making any physical electrical repairs.

  12. Check battery age and health. Although the battery may be longer than the life of the device, the situation is sometimes reversed. Check the health and age of the battery to see if it needs to be replaced. If your device has a removable battery, replace the battery and see if the problem persists. You can also calibrate an older battery.

  13. Check the charger’s compatibility. It is easy to accidentally use a physically compatible cable that does not work completely. Laptop chargers are more cumbersome, as you can rarely replace each other without any problems. In addition, only the right combination of adapter and cable can benefit from all the features of the device. If you think you are using an incompatible cable, get one that is compatible with your device.

  14. Test with a multimeter. With a multimeter you can check the cable and the wall socket to limit potential problems.

    • To check the socket, connect the probes to the multimeter and set it to AC, then insert the black probe into the neutral port and the red probe into the hot or positive side of the socket. If the socket works, check the cable.
    • To check the cable, turn the multimeter center knob to the resistance setting (Ohm or Ω). Then touch the same pin at opposite ends of the cable with the multimeter’s two probes. If the multimeter shows 0, the cable is functional. An infinity means that the thread is broken and must be fixed or replaced.
    • Check the adapter. With the multimeter set to detect AC voltage, connect the adapter to the wall and check the connectors that will conduct current. If you do not get a measurable voltage from the adapter, it may not supply power, and you may need to replace it.

    A data cable such as USB can only be tested on its two power outlets, so-called ground and voltage pins. Look at a pinout for the contact type and find these force-bearing pins (often marked earth, GND, V + or 5V) on the diagram.

  15. Contact customer support. If you can not fix the device, contact the manufacturer to find out your options. If the device is not covered by the warranty or will cost too much to repair, you may need to purchase a new device.
