How To Charge A Bluetooth Speaker Without A Charger – DIY Solutions

Charge a BLuetooth Speaker

Every music lover knows the frustration of reaching for their beloved Bluetooth speaker only to realize the battery has drained, and to add insult to injury; the charger is nowhere to be found. But what if I told you there were ways to breathe life back into that speaker without the designated charger?

Today, I’ll walk you through innovative, safe, and effective methods to power up your device. So, the next time you’re in a charger-less crunch, you’ll be ready!

Your Speaker’s Power Needs

Every Bluetooth speaker is a little different, but one thing remains consistent: they all need power. Before diving into alternative charging methods, it’s vital to grasp the basics of your energy requirements.

Voltage and Current Basics

Bluetooth speakers, like many gadgets, operate within a specific voltage and current range. In layman’s terms:

  • Voltage (V) is the ‘pressure’ behind the electric current.
  • Current (A or mA) is the flow rate of the electricity.

Knowing the appropriate voltage and current for your speaker is critical to prevent damage. Charging with too high a voltage can cause overheating or even fry the device. Conversely, too low a voltage might not charge the speaker at all.

Finding Specifications

Almost every speaker has its power requirements labeled. Typically found on the bottom or rear, you’ll spot a series of numbers – for example, “5V/1A.” This indicates a requirement of 5 volts and 1 amp.

  • Check the manual.
  • Visit the manufacturer’s website for specs.
  • Look for the information tag or sticker on the speaker.

Once you know the specs, you can confidently search for alternative charging methods compatible with these requirements.

Innovative Charging Solutions

Chargers are but one way to refuel our devices. Explore the following alternatives to keep your Bluetooth speaker rocking without its designated charger.

Using a Universal Charger

Charging with Universal Charger

Universal chargers, as the name suggests, are designed to fit a wide variety of devices. They come with multiple tips and adjustable voltage settings. Here’s how to utilize them:

  1. Match the Specs: Ensure the universal charger supports your speaker’s voltage and current needs.
  2. Choose the Right Tip: Find the charging tip that fits snugly into your speaker’s charging port.
  3. Monitor the Process: It’s a good practice to check periodically for overheating when using alternative charging methods.

USB Charging

Charge with USB


Many modern Bluetooth speakers can charge via a USB port. Here’s a quick guide:

  • Identify the USB Type: Familiarize yourself with the USB type your speaker uses (Micro-USB, USB-C, etc.)
  • Locate a Power Source: This can be a computer, TV, or any device with a USB port. Even power banks can come to the rescue.
  • Monitor the Charge: As with the universal charger, ensure your speaker doesn’t overheat.

Embracing Alternative Energy

While traditional methods dominate the charging game, embracing unconventional energy sources can be both efficient and eco-friendly. Let’s take a brief tour of these exciting possibilities.

Solar Chargers

Harness the power of the sun with solar chargers. These devices contain photovoltaic panels that convert sunlight into electricity:

  • Pick the Right Size: Solar chargers come in various sizes. For a Bluetooth speaker, a smaller, portable solar panel should suffice.
  • Place in Direct Sunlight: To maximize efficiency, ensure the panels receive unobstructed sunlight.
  • Advantages: This method is eco-friendly and perfect for outdoor adventures or power outages.

Hand-Crank Chargers

If you’re feeling a bit more hands-on, these devices convert manual energy into electric power:

  • Understand the Output: Not all hand-crank chargers output the same energy. Choose one that matches your speaker’s specifications.
  • Duration: Typically, several minutes of cranking can provide an hour of playback, though this varies by device.

DIY Charging Methods

When conventional methods fail or aren’t accessible, creativity can save the day. Delve into these DIY methods to charge your Bluetooth speaker.

Charging with Another Device’s Charger

Many electronic devices use similar chargers with interchangeable voltage and current settings. Your other gadgets might just be the answer:

  • Check Compatibility: Look at the specifications of both chargers to ensure they match. If you find another charger with the same voltage and current, it’s worth giving it a shot.
  • Fit Check: Make sure the plug fits well into the charging port without force.
  • Caution: Although the ratings might match, always monitor the charging process for safety.

DIY Battery Pack

If you’re somewhat tech-savvy and have a bit of time, creating a DIY battery pack can be an adventurous alternative:

  • Determine Power Requirements: As always, know your speaker’s voltage and current.
  • Gather Materials: Procure rechargeable batteries, a battery holder, and some basic wiring tools.
  • Connect: Wire the batteries in a configuration that matches the speaker’s voltage. For instance, if it requires 5V, use five 1V batteries in series.
  • Safety First: Make sure to properly insulate your connections to avoid short circuits.

The Future of Charging Technology

As technology continually evolves, the ways in which we charge our devices are also undergoing revolutionary shifts. Here’s a glimpse into the future:

Wireless Charging Stations

While still in its early stages for devices like Bluetooth speakers, wireless charging is rapidly gaining momentum:

  • How it Works: Devices are placed on a charging mat, and energy is transferred without cords via electromagnetic fields.
  • Universal Compatibility: Future wireless charging hubs aim to be universally compatible, putting an end to the tyranny of countless cables.

Motion-Powered Charging

Imagine if your Bluetooth speaker could charge just by moving or shaking it:

  • Piezoelectric Effect: Some materials generate voltage when mechanical stress is applied. This principle might soon be incorporated into devices to allow for motion-based charging.
  • Potential Benefits: Perfect for on-the-go individuals, especially during activities like hiking or dancing.
