🔌 Some later Transformer Pads (T100 series) switched to micro‑USB or USB‑C — this adapter won’t fit
🧯 Using the wrong adapter may cause charging faults or no power
🧪 Always confirm the tablet’s underside label (15V 1.2A) before plugging in

🔌 Use only with ASUS tablets that accept the wide 40‑pin plug
🧪 If tablet won’t charge, inspect connector for dust or bent contacts
