If you are dealing with a USB phone charger, then you can try replacing the USB cable to see if that makes a difference. You can also consider repairing or replacing your charger. But if you are trying to repair your charger it is essential to make certain what you are doing.

In most instances, users dealing with noisy chargers don’t worry much about it. But sometimes the problem of high-pitched buzzing noise is a cause for major concern. It may even be an indication that your charger is prone to becoming a fire hazard. Potential Causes of Buzzing Noise in Your Charger 1. Instability of the Magnetic Field If your charger begins to make a buzzing noise or high-pitched noise, then that indicates an underlying problem that needs to be fixed. In most cases, fast charging usually leads to loud noise as there is too much power moving through the components. How to Take Good Care of Your Charger If the capacitor isn’t working properly then you need to replace it by buying a new charger. Make sure to do some research on the specific charger you are using to work out the most cost-effective solution. Replace the Components of Your Charger

It is normal for chargers to make quiet humming but if you notice unusual noise from your charger. It may mean that your charger is damaged, defective or overheating. However, if you realize the adapter is not working, then you need to fix it or replace it through the company, that’s if it’s still within the warranty period. Inspect the Voltage Output Similar to the transformers on the roadside, the small transformer inside your charger can make vibrations and induce noise. This usually occurs when your phone battery is very low. Once your battery is almost charged the buzzing noise will stop. This is normal and there is nothing to be worried about. 6. Fast Charging

You can try to patch some parts of your charger for a temporary fix depending on the extent and location of the damage. You can also buy a new charger from a reliable supplier to ensure it’s of high quality and your device brand type. Plug Your Charger Into a Different Outlet Even the most expensive brand-name chargers will eventually break down. If you have been using yours for several years then it is likely there may be some signs of wear. For example, they can be bent in several places or the charging port has become loose. However, when there is a problem with your charger you may hear a buzzing noise. 9. A Defective Outlet

Even though many people take good care of their smartphones and laptops, they usually abuse their chargers. For instance,y may leave their chargers on the floor where somebody can easily stumble over the cable. Sometimes people may heavily bend and twist the cable to make it fit in a bag. Over time this careless habit may cause physical damage to the charging device. 4. Broken Components in Your Charging Device If you inspect your charger for damage and can’t find anything wrong with it. Then you need to unplug your charger and try it on a different power outlet.

Off-brand chargers usually don’t carry the right voltage and due to this they often make odd noises. Sadly many of these off-brand chargers are poorly designed and don’t follow the ideal safety and quality standards. Due to this the chargers often don’t work properly even when they are new. These off-brand chargers do not carry the right voltage and this can damage your device battery after a short term. 8. Old Charger Some of the possible causes of the buzzing noise in your charger include; electrical issues, physical damage, transformer issues, old chargers, and off-brand chargers. One way to get rid of the noise in your charger is to deactivate the fast charging. Simply switch off the fast charging feature on your device and see if the noise stops. In this article, we will help you help discover why your charger makes a buzzing noise and how to fix it. When It’s Normal for Your Charger to Make Noise The readings of the voltmeter should be steady, however, if the readings increase or decrease suddenly then it’s an indication that the capacitor doesn’t allow an equal flow of power.There are several types of charge but one common thing is that they all have a similar set of basic parts. Generally, these components include; Most fast chargers use and convert more power within a short term than the normal pace charger. When you are using a fast charger it increases the current extremely hence causing the magnetic field to become unstable. This can lead to the amplification of sound waves. The sound waves will become very loud when the current reaches a certain level. 7. Off-brand Chargers If the magnetic sheet steel inside your charger begins to expand all by itself. Then it is likely for it to create vibrations. The vibrations will induce high-pitched noise due to the variations in the magnetic field. There is nothing to worry about when this occurs as it is normal. 2. Electricity Issues This usually happens when your phone battery is very low and due to this, the charger works extra hard to take up more power. The power current flows through the transformer to charge your device. This can be relative to a roadside transformer making a humming noise.

Bear in mind that replacing your charger may cost much less than trying to repair the components of your old charger. Deactivate Fast ChargingHowever, some models may have resistors and regulator chips.No matter how different the structure of your charger maybe you will still hear a buzzing noise if any of these components breaks. 5. Transformer Issues Inspect to be sure that the noise is coming from your charger and not your wall outlet. If you realize the noise is coming from your wall outlet, we recommend you call up an electrician right away as your home may be at risk of fire or other dangerous events. 3. Physical Damage The first thing you need to do when your charger starts making a buzzing noise is to look out for damage. Physical damage can be the cause of the sudden buzzing noise in the charger. If there is a problem with your laptop charger, then you need to run an AC adapter test through the diagnostic tools on your laptop. If your laptop has that capability it will be found in settings or the diagnostic menu.
