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.

Can the PAX Four be used with concentrates?

No. The PAX Four is dry herb only. PAX removed concentrate support to optimize the oven for hybrid heating. For concentrates, look at the PAX Plus or dedicated concentrate vaporizers.

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.
