Bottom Line
This temperature control travel mug by LEJIEYIN offers solid temperature maintenance, safety features, and convenient car compatibility with a sleek LCD display, making it a smart option for hot beverage lovers on the move. However, it carries potential reliability risks—particularly around the power cord and electrical connections—that may impact durability. If you want a dependable travel mug with excellent heating and temperature control, this is a decent choice but be prepared for possible troubleshooting or poor customer support. For a cordless, more hassle-free experience, you might want to explore alternative travel mugs that don't rely on a wired 12V connection.
