⚠️ Things to Watch Out For
📉 Verify whether the monitor has DC IN 12V or an IEC C13 AC inlet — only the former uses this adapter
🔌 Connector is larger than standard 5.5 mm barrels — won’t fit smaller jacks
🧯 Always confirm device label or manual before plugging in
📏 Some monitors require higher current (up to 4A–5A) — check amperage rating
 
🛠️ Quick Tips for Beginners
🧭 Look for “DC IN 12V” near the monitor’s power jack
🔌 Confirm connector size: 6.0 mm outer, 4.4 mm inner, with pin
🧪 If device won’t power on, inspect barrel for bent pin or loose fit
🧯 Label clearly to avoid mix‑ups with 5.5 mm barrel adapters
