Not just for music. Here’s how to charge your phone using a portable speaker.

In a world where smartphones have become an integral part of life, the issue of charging devices often becomes critical. However, not everyone is aware that modern portable speakers can serve as a life-saving power source for phones.

"Telegraf" will discuss the specifics of this charging method. First and foremost, it’s important to note that not every speaker can charge a phone.

To do so, it must have a PowerBank feature and a corresponding USB port for power output. Typically, this capability is found in mid-range and high-end speakers.

How does this work in practice? The process is quite simple:

• Ensure the speaker has enough battery charge;
• Locate the USB port on the speaker marked with OUT or a special charging symbol;
• Connect the phone to the speaker using a USB cable;
• On some speaker models, you may need to press a specific button to activate the charging mode.

Experts in digital technology note that this charging method has its peculiarities. The speaker will charge the phone more slowly than a standard mobile charger.

It’s crucial to consider that using a charging speaker will significantly reduce its battery life. If you plan to use the speaker for an extended period to play music, it’s better to keep the PowerBank function as a backup for emergencies.

When playing music and charging the phone simultaneously, the speaker's battery will drain twice as fast, so it’s recommended to either listen to music or charge the phone.

Manufacturers of portable speakers are increasingly adding this feature to their devices, recognizing its practicality for users. This functionality becomes especially useful during travels, picnics, or other situations where access to a power outlet is limited.

However, specialists advise against relying on the speaker as a primary charging device. It is more of an emergency option that can save you in critical situations when a regular charger is not available.

Earlier, "Telegraf" reported that a power bank can "kill" a phone's battery.
