⚠️ Things to Watch Out For
📉 Must be 15V — lower‑voltage adapters (5V USB) won’t charge, higher voltages may damage the shaver
🔌 Connector is Philips proprietary barrel — not compatible with standard DC plugs
🧯 Always confirm “DC IN 15V” on the shaver body before substitution
📏 Some newer Philips models use USB‑C — HQ8505 is not compatible
 
🛠️ Quick Tips for Beginners
🧭 Look for “Philips Norelco” and model number on the shaver or trimmer
🔌 Confirm connector: 2‑prong plug, not USB or magnetic dock
🧪 If device won’t charge, inspect barrel contacts for wear or corrosion
🧯 Label clearly to avoid mix‑ups with other Philips adapters
