⚠️ Things to Watch Out For
🚫 Not interchangeable with 24V or 36V chargers — always match voltage

📉 Overvoltage may damage 24V systems — confirm battery specs
🧪 Check polarity and pinout before using aftermarket replacements
🧯 Avoid forcing into mismatched ports — may bend pins or short contacts
 
🛠️ Quick Tips for Beginners
🧭 Look for “29.4V 2A” on the adapter label to confirm match
🔌 Match the 3‑pin round plug — don’t substitute with barrel or 2‑pin
🧪 If device won’t charge, inspect plug pins for corrosion or misalignment
🧯 Label adapters clearly to avoid mix‑ups with 24V or 36V chargers
