How Do Bluetooth Speakers Get Power? (EXPLAINED 2023)

Bluetooth speakers are all the rage these days. They are convenient for use in unexpected circumstances due to their compact size, portability, and user-friendliness. But how do they get power? 

Bluetooth speakers work by transmitting sound over a short distance using Bluetooth technology. To do this, they need a source of power—typically a battery. This power is usually provided by a USB connector or adapter.

In this blog post, we will explore the different ways Bluetooth speakers get power and the pros and cons of each. In addition to this, we will provide some guidance on how to choose the most suitable Bluetooth speaker for your requirements. 

Let’s get started!

How do Bluetooth speakers get power?

Bluetooth speakers are powered by batteries, either disposable or rechargeable. In order to power a Bluetooth speaker, it must first be connected to an appropriate source of power—typically a USB port on a computer or an outlet with a USB charging cable. 

What are the Different Types of Bluetooth Speakers?

Different Types of Bluetooth Speakers

On the market, you can find a few distinct varieties of Bluetooth speakers, each of which has its own set of distinctive characteristics that may or may not make it the ideal speaker for your requirements.

Portable Bluetooth Speaker

The portable speaker is the first kind of Bluetooth audio device available. These speakers are often quite portable due to their small size and low weight, making them ideal for use in a variety of settings. They are available in a wide variety of forms and sizes, and their many uses include acting as a phone stand, watching movies, or listening to music. These speakers use batteries to get power.

Home Bluetooth Speaker

The home speaker is the next kind of Bluetooth speaker that you can purchase. The sound output of these speakers is often greater than that of portable speakers since they are intended for usage in a home setting. They often come with additional capabilities, such as internal amplifiers, surround sound capability, and even terrestrial radio tuners that are incorporated into the device. These speakers can have batteries or may not.

Multi-Room Bluetooth Speaker

The final shape of the Bluetooth speaker that can be bought is one that can be used in many rooms. You can listen to music in multi-locations at the same time thanks to the fact that these speakers can connect to multiple devices located in different rooms. In addition, they often offer a greater feature set than house speakers, including voice control and the ability to interact with smart assistants. These kinds of speakers mostly don’t have batteries because they are not very portable.

What Is the Difference Between Bluetooth Speaker and Normal Speaker?

A Bluetooth speaker is a type of speaker that uses Bluetooth technology to connect to devices like phones and tablets. This type of speaker is typically smaller and thinner than traditional speakers, making them easier to carry around. Additionally, Bluetooth speakers often have more powerful sound than standard speakers. However, they may not be as loud or as clear when used in larger spaces.

Normal speakers are typically bigger and heavier than Bluetooth speakers, and they use a regular wired connection to power the audio output. They are generally better quality than Bluetooth speakers when it comes to sound reproduction, and they can be used in larger spaces without worry about interference from other electronics. Normal speakers are also usually more expensive than Bluetooth speakers.

How Long Do Batteries Last in Bluetooth Speakers?

According to the information provided by the manufacturer, the battery that powers a Bluetooth speaker should last for around a year on average. However, this time will vary depending on how often the speaker is used and how much power it’s being used. 

Can I Charge My Bluetooth Speaker While Using It?

Yes, it is possible to charge the speaker while it is in use. Bluetooth speakers typically have a USB port to plug in a charging cable. This will allow the speaker to recharge quickly and maximize its battery life.

How Do I Extend the Battery Life of My Bluetooth Speaker?

Here are a few tips on extending the battery life of your Bluetooth speaker.

Use it Indoors

When you use your device inside, the power output is often reduced, which might cause the battery to deplete more rapidly. So if possible, try to keep your Bluetooth speaker used indoors where the audio output is low.

Keep an Eye On the Battery Level

Once your Bluetooth speaker’s battery is down to a certain point, it will display a red “low battery” warning notification. If you find that this happens often, it might be helpful to recharge your speaker more often or to invest in a longer-lasting battery option like lithium-ion or Li-ion polymer cells.

Avoid Overcharging Your Batteries

Overcharging can also deplete the battery quickly – so be sure not to put your Bluetooth speaker into storage with chargers still attached!


There are a few ways that Bluetooth speakers get power. The most common way is through an AC adapter, which plugs into the wall and provides power to the speaker. Many newer Bluetooth speakers also come with a rechargeable battery, which can be charged using a USB cable or using an outlet with a USB port.
