🧯 Avoid third‑party clones with weak pins — may cause “not charging” issues
🌀 Excess heat or frayed cables can cause power dropouts
🧪 Always confirm laptop’s required wattage before swapping adapters
 
🛠️ Quick Tips for Beginners
🧭 Check underside of laptop or original charger for voltage and connector type
🔌 Use only with Apple laptops rated for 24V and 9.5 mm fat‑pin input
🧪 If laptop won’t charge, inspect fat center pin for bending or corrosion
🧯 Label adapters clearly to avoid mix‑ups with 65W fat‑pin or MagSafe chargers
