🔌 Barrel is smaller than the common 2.1 mm or 2.5 mm plugs — only fits GBC/Pocket
📉 Many aftermarket adapters are unregulated — stick to regulated 3V output
🧪 Always confirm polarity (center‑positive) before plugging in
🧯 Using higher voltage (5V, 6V) can damage the console
 
🛠️ Quick Tips for Beginners
🧭 Look for “3V 1A” and “MGB‑005” on the adapter label to confirm match
🔌 Match the slim 2.3 mm × 0.7 mm barrel — don’t force larger plugs
🧪 If console won’t power on, check for loose fit or worn jack
🧯 Label clearly to avoid mix‑ups with 5V or 6V adapters
