The Vanzon V40 speaker is a popular choice for many music lovers, thanks to its compact size and powerful sound.

However, like any electronic device, it can encounter problems from time to time. One of the most common issues faced by users is when the speaker stops charging.

This can be frustrating, especially if you use the speaker often and rely on it for your music needs.

If you’re facing this problem with your Vanzon V40 speaker, don’t worry. We’ve put together a troubleshooting guide to help you identify the cause of the issue and find a solution. In this guide, we’ll discuss 7 possible fixes for your Vanzon V40 speaker not charging.

First and Foremost:

Before we dive into troubleshooting your Vanzon V40 speaker not charging issue, let’s consider three important points to respect your time:

If you’ve recently bought a Vanzon V40 speaker and it’s already causing charging problems, it’s advisable to seek a refund.

Save yourself both money and time by exploring alternative speakers in the same price range, such as “Hseok Bluetooth Speakers V40” and “OontZ Angle 3” which offer better performance.

Typically, the Vanzon V40 speaker has a lifespan of 2-3 years. If you’ve been using it for that duration, you’ve received good value for your money.

Attempting to fix a speaker at this stage may only provide a short-term solution, perhaps an extra month or two.

If you’re continuing to use it post-fix, there’s a risk of recurring issues, making it less than ideal.

If you’ve had your Vanzon V40 for less than three years, you can explore the practical fixes mentioned below.

These solutions are intended for speakers within their reasonable lifespan, offering you a chance to extend the usage without immediate replacement.

Why Is Vanzon V40 Speaker Not Charging?

The Vanzon V40 speaker may fail to charge due to various reasons. Some possible causes are:

  • Defective charging cable or port
  • Debris or damage in the charging port
  • Battery issues
  • Software or firmware issues
  • Charging indicator

How to Fix Vanzon V40 Not Charging

Check the Charging Cable

The first thing you need to do when your Vanzon V40 speaker is not charging is to check the charging cable. The problem may be as simple as a faulty or damaged cable, which can easily be replaced.

To ensure that the charging cable isn’t the issue, try using it with another device and see if it charges. If it doesn’t, then you’ll need to replace the cable.

Clean the Charging Port

Cleaning the charging port is another potential solution to a Vanzon V40 speaker not charging. Over time, debris, lint, and dust can accumulate in the charging port, obstructing the battery connectors and preventing a secure connection with the charger. To clean the charging port, follow these steps:

  • Inspect the charging port with a bright light for debris.
  • Turn off the Vanzon V40 speaker before cleaning.
  • Use a soft tool like a toothpick or compressed air to remove debris gently.
  • Dampen a cloth with rubbing alcohol or distilled water.
  • Clean the port gently with the damp cloth.
  • Allow the port to dry completely before use, using a low setting hair dryer if needed.
  • If issues persist, repeat cleaning or seek professional help.

Try a Different Power Source

At times, the problem you’re encountering with your speaker might not actually stem from the speaker itself, but rather from the power source you’re utilizing for charging.

Specifically, if you have a habit of charging your Vanzon V40 speaker by connecting it to a USB port on your computer, it could be beneficial to switch your charging method. Consider using a wall charger or a portable power bank as an alternative.

This suggestion comes from the fact that not all USB ports are created equal, and some may not offer a sufficient amount of power needed to efficiently charge your speaker.

Consequently, by opting for a different power source, you might find that your speaker charges more effectively and consistently, leading to an overall better user experience.

Restart Your Speaker

Just like any electronic device, a simple restart can often fix minor issues with the Vanzon V40 speaker.

To do this, turn off your speaker and unplug it from the power source for a few minutes. Then, plug it back in and turn it on again to see if it starts charging. This may seem like a simple solution, but it can sometimes do the trick.

Reset Your Speaker

If restarting doesn’t work, you can try resetting your Vanzon V40 speaker. Resetting your speaker can help fix any software glitches that may be causing the charging issue.

Here’s how to reset the Vanzon V40 speaker:

  • Turn off the speaker.
  • Press and hold the power button and the volume down button simultaneously for about 10 seconds.
  • Release the buttons when the speaker turns on and the LED light starts flashing.
  • Wait for the speaker to fully reset.
  • After resetting the speaker, try charging it again to see if it works.

Check the Battery Life

If none of the above solutions work, it’s possible that the problem lies with the battery. Remember, Vanzon uses a high-quality 3600mAh lithium-ion battery which has a limited lifespan.

If the battery has reached its lifespan, it may not hold a charge anymore and will need to be replaced. You can check the battery life by using the Vanzon app or consulting the user manual.

Contact Customer Support

When all else fails, it’s time to seek professional assistance. Contact the manufacturer’s customer support and provide detailed information about the issue, the steps you’ve taken, and the troubleshooting results.

They may offer additional guidance or explore the possibility of providing a replacement for your Vanzon V40 speaker.

Additional Tips:

  • Use the Original Charging Cable and Adapter: Stick to the original accessories that came with your Vanzon V40. Using third-party cables or adapters may lead to compatibility issues and hinder the charging process.
  • Avoid Extreme Temperatures: Charging your speaker in extreme temperatures can adversely affect battery performance. Ensure the charging environment remains within the recommended temperature range for optimal functionality.
  • Please don’t Use the Speaker While Charging: Although it might be tempting, refrain from using your Vanzon V40 while it’s charging. This practice can generate additional heat, potentially exacerbating charging issues and prolonging the troubleshooting process.


By meticulously following these troubleshooting steps and additional tips, you increase the likelihood of identifying and rectifying the charging issues plaguing your Vanzon V40 speaker.

Patience and a systematic approach are essential as you work through each potential solution. If uncertainties persist, contacting the manufacturer’s support team remains a valuable option for professional guidance and potential resolution.

Remember, the goal is to restore your Vanzon V40 to its optimal charging performance.
