⚠️ Things to Watch Out For
🚫 Not interchangeable with 12V or 19V adapters — always confirm 9V label
🔌 Barrel size is smaller than 5.5 mm — won’t fit larger jacks
📉 Some players ship with 9V car adapters — don’t confuse with AC brick
🧪 Always confirm polarity (center‑positive) before use
🧯 Avoid using with laptops or monitors — voltage mismatch
 
🛠️ Quick Tips for Beginners
🧭 Look for “9V 2A” and “4.0×1.7 mm” on the adapter label to confirm match
🔌 Match the slim yellow‑tip barrel — don’t substitute with 5.5 mm plugs
🧪 If player won’t power on, check for loose fit or worn jack
🧯 Label adapters clearly to avoid mix‑ups with 12V or 19V chargers
