Step 1. Read ohms on the WINDBAR coil, pod, or insert. If the print is missing, resistance is unknown and the tool should sit unused.

Step 2. Pick inhale style. MTL is the usual pocket starting point on the WINDBAR hooks.

Step 3. Optional: tap WINDBAR D95 or WINDBAR D91 4.4V. Do not tap those hooks because a Geek Bar listing looked similar.

Formula on the tool: P = V² / R and I = V / R. Educational math: 4.4 V and 1.0 Ω → P = 19.36 W, I = 4.4 A. That math is not an order to fire 19.36 W. The insert wins.

Do not enter 0.2 Ω or 0.4 Ω into a sealed WINDBAR pocket device because a generic RDL/DL table row exists. Those rows are inhale-style examples, not Geek Bar certificates and not D91 settings.
