You will need to purchase a standard 18650 rechargeable cell separately and install it, making sure to observe the correct positive and negative polarity as marked on the board.\u003c\/p\u003e\n\n\u003ch4\u003eQ: Can I use this PAM8403 amplifier board without a TF card or USB drive?\u003c\/h4\u003e\n\u003cp\u003eA: Yes! The XH-A150 supports three input modes: Bluetooth wireless streaming, TF\/SD card playback, and USB flash drive playback. If no card or drive is inserted, simply pair it with any Bluetooth device (smartphone, tablet, laptop) to stream audio wirelessly up to 20 meters.\u003c\/p\u003e\n\n\u003ch4\u003eQ: What type of speakers are compatible with this amplifier board?\u003c\/h4\u003e\n\u003cp\u003eA: The XH-A150 PAM8403 board is compatible with passive speakers (those that require an external amplifier). It delivers up to 5W per channel, so speakers rated in the 3–8W, 4–8 ohm range are ideal for optimal audio performance in DIY builds and custom enclosures.\u003c\/p\u003e\n\n\u003ch4\u003eQ: Can I power the board without a battery using USB only?\u003c\/h4\u003e\n\u003cp\u003eA: Yes. The board accepts DC 5V via its Micro USB port, so you can power it directly from a USB power adapter, power bank, or computer USB port without needing the 18650 battery installed.\u003c\/p\u003e\n\u003cscript type=\"application\/ld+json\"\u003e{\"@context\": \"https:\/\/schema.org\", \"@type\": \"FAQPage\", \"mainEntity\": [{\"@type\": \"Question\", \"name\": \"Does the XH-A150 Bluetooth amplifier board come with a battery?\", \"acceptedAnswer\": {\"@type\": \"Answer\", \"text\": \"No, the 18650 lithium battery is not included with the XH-A150 amplifier board.
