Twenty tabs in. One table out.

1. 01

   Sources

   Official manufacturer specs and datasheets first, then technical documentation, cross‑checked against reputable reviews and product databases.

2. 02

   Verification

   Source validation → cross‑reference → unit standardization → format normalization → manual review of flagged or unusual values.

3. 03

   Normalization

   One unit per field (g, mm, mAh, W, nits). The same field names for every product in a category, so rows line up.

4. 04

   Like with like

   Comparisons stay inside one category. You can’t put a phone against a laptop.

5. 05

   Rankings

   Sorted by one measurable metric, in the direction that makes sense for it: lower weight first, higher capacity first.

6. 06

   Corrections

   Wrong value? Report it. Specs are updated when manufacturers publish corrections, and rankings recalculate as products are added.

No paid placement. DuelVS doesn’t accept payment to influence rankings, comparisons or product visibility.
