The Coleman Exponent F1 Power PZ weighs 146g (+ gas); boil time 2min 2sec to 5min 5sec; small packed size; 16cm diameter pan supports; 4 support arms for extra pan stability; wide flame head for better boil performance; includes piezo ignition. But best boil time is only available with fresh gas canister; not the lightest gas burner.
The Coleman Exponent F1 Power PZ is a good burner for wider pans if low weight is not a priority
