Step 1. Read CHROMA WING: sealed, not user refillable, no replaceable pod.

Step 2. Read 4.4V next to 850 mAh. If a listing never prints 4.4V, it is not matching this platform page.

Step 3. Read 0.45 Ω / 0.9 Ω. Which ohm is in a given sample is unknown until the insert says so.

Step 4. Confirm 96 × 51 × 27 mm on spec-plate language, not on a Geek Bar lifestyle photo.

Step 5. If you want 4.4 V in math, open the WINDBAR ohm’s law calculator. Packaging and mode limits win. Do not use an off-site calculator.
