Question about that 'Insta-Heat' portable coffee mug ad I keep seeing
Spent $65 on it after the ad promised boiling water in 90 seconds from any USB port, but it barely got warm after 5 minutes plugged into my car. The return process wanted me to pay $15 for shipping back to a warehouse in New Jersey. Has anyone actually gotten this thing to work as shown, or is it just a fancy paperweight?
My friend bought one of those for truck stops. It took three minutes to get lukewarm from a power bank she said was fully charged. The whole thing feels cheap, like the plastic lid doesn't even screw on straight. I looked it up and the company has a whole separate website just for handling complaints. You're better off just getting a normal thermos and filling it at a gas station.
Three minutes to lukewarm is pretty sad. Did she say what the power bank's output was? A lot of those cheap warmers need a specific amperage they never tell you about.
