Not That Tesla — Funny Nikola Tesla Coffee Mug

He pioneered alternating current. He designed the modern electrical grid. He held over 300 patents and predicted Wi-Fi, smartphones, and renewable energy decades before any of them existed. He died alone in a New York hotel room in 1943, broke, with his greatest invention credited to someone else. Then in 2003, a man named Elon bought the rights to his last name.

This 11oz ceramic mug features Nikola Tesla in his off-duty uniform — fleece zipped, mustache trimmed, Tesla coil in hand, dignity intact — the actual inventor whose name you keep seeing on luxury sedans, delivering the only clarification he has been entitled to for the past 20 years: Not That Tesla. The original.

Drink your coffee. Power the grid. Survive your Monday.

Part of the Off-Duty Scientists Collection — where history's greatest minds finally clock out.
