On the other hand, if your speaker uses a micro-USB or mini-USB connector, you may still be able to charge it via USB, but the power delivery might be restricted.
For speakers with higher power requirements or those that use DC power jacks, USB to USB charging is not a viable option. You’ll need to use a dedicated power adapter or a wall outlet to charge these speakers.
What About USB-C and USB-PD?
With the advent of USB-C and USB Power Delivery (USB-PD), the possibilities for charging speakers have expanded. USB-C, being a reversible connector, offers faster data transfer rates and increased power delivery capabilities.
USB-PD, a specification developed by the USB Implementers Forum, enables devices to negotiate higher power levels over a single USB-C cable. This allows for faster charging and the ability to power larger devices, like laptops.
Some newer speakers, especially those designed for mobility, may incorporate USB-C connectors with USB-PD capabilities. This enables faster charging and higher power delivery, making it possible to charge these speakers via USB-C.
Charging a Speaker with a Power Bank
Another option for charging your speaker is to use a power bank. A power bank is a portable battery pack that can charge your devices on the go. Many modern power banks feature USB-A, USB-C, and even DC output ports, making them versatile charging solutions.
When choosing a power bank to charge your speaker, consider the following factors:
- Capacity: Look for a power bank with a sufficient capacity (measured in mAh) to charge your speaker multiple times.
- Output: Ensure the power bank has an output port that matches your speaker’s power connector (USB-A, USB-C, or DC).
- Voltage and current: Verify the power bank’s output voltage and current can meet your speaker’s power requirements.
Conclusion
Can you use USB to USB to charge a speaker? The answer is, it depends on the speaker’s power requirements and connector type. While some speakers can be charged via USB, others require a dedicated power adapter or wall outlet.
When it comes to charging your speaker, consider the following:
Know your speaker’s power requirements and connector type
Choose the right charging method: USB, power bank, or wall outlet
