Vessel Core vs Vessel Core

These are the same Vessel Core device in two finishes, so the hardware is identical: 260mAh battery, four voltage settings (2.4V, 2.8V, 3.2V, 3.6V), wide 510 crown, USB-C charging and Rover Case compatibility. The Merlot has far more owner feedback (1,508 ratings at 4.8) and its known gripe is the 15-minute auto shutoff that needs five clicks to wake. The Soleil rates slightly higher (4.9 from 225) and owners single out its finish and airflow, but some find the button recessed and stiff. Pick on color and case fit, not performance.

• Choose the Core Merlot if you want the deeper red finish and the reassurance of a much larger, well-established record of owner reviews.
• Choose the Core Soleil if you prefer the lighter finish and want the model whose smaller owner base still rates it highest.
