Is the PAX Four better than the PAX 3?

For vapor quality, yes. Hybrid heating produces 50% denser vapor than the PAX 3's conduction-only system (PAX Labs, 2026). But the PAX 3 had longer battery life (3500 mAh), app control, and concentrate compatibility.

What temperature should I use on the PAX Four?

Start at 190 degrees C (Mode 1) for pure flavor. Mode 2 (200 C) offers balanced vapor. Mode 3 (210 C) produces thick clouds. Mode 4 (220 C) is for maximum extraction at the expense of flavor.
