⚠️ Things to Watch Out For
📉 Using a lower-wattage adapter (65W/90W) on these laptops may cause throttling or prevent charging
🔌 Connector must match — not interchangeable with Dell’s slim-tip or USB-C
🧯 Avoid third-party clones without smart chip — high-performance models may reject them
🌀 Excess heat or frayed cables can cause intermittent charging
🧪 Always confirm laptop’s required wattage before swapping adapters
 
🛠️ Quick Tips for Beginners
🧭 Check underside of laptop or original charger for voltage and wattage
🔌 Use only with laptops rated for 180W barrel input
🧪 If laptop reports “adapter not recognized,” inspect center pin and cable integrity
🧯 Label adapters clearly to avoid mix-ups with 65W/90W barrel chargers
