Battery
The Vaporesso XROS 5 Mini wins on battery outright, with a 1500 mAh cell against the Vaporesso XROS 4 Mini’s 1000 mAh, meaning more capacity to get through the day. It also charges faster, reaching 80% in 15 minutes versus 45 minutes on the Vaporesso XROS 4 Mini, helped by its 2 A charge current compared to 1 A on the older model. Together, larger capacity and quicker top-ups make the Vaporesso XROS 5 Mini the clear battery winner.
Performance
Performance is a tie: both devices top out at the same 30 W max output, neither offers variable wattage, and both include adjustable airflow. The main practical difference is coil choice, with the Vaporesso XROS 5 Mini offering five resistances (0.4Ω to 1.2Ω) against two on the Vaporesso XROS 4 Mini (0.6Ω / 0.8Ω), but there’s no comparable data to declare a winner on that spec alone, so overall performance remains even.
Convenience
The Vaporesso XROS 4 Mini takes the convenience win on weight alone, at 46.5 g against 65.2 g for the Vaporesso XROS 5 Mini, making it the lighter and likely more pocketable device. Both use a Type-C port and neither has a display screen, so those points don’t separate them, leaving weight as the deciding factor here.
The Vaporesso XROS 4 Mini suits vapers who prioritise a lighter, more compact device and don't mind a slower charge.
The Vaporesso XROS 5 Mini suits vapers who want longer battery life and faster charging, and don't mind extra weight.
The verdict
Neither device comes out on top across the board. The Vaporesso XROS 5 Mini is the stronger choice for battery life and charging speed, while the Vaporesso XROS 4 Mini stays lighter and more compact. Performance is essentially matched, with the extra coil options on the Vaporesso XROS 5 Mini a possible tie-breaker for those who want more resistance choices, though that alone isn’t enough to call a category winner. Which model suits better depends on whether battery endurance or a lighter build matters more day to day.
