What to know before buying

Listing details to confirm

The listing describes accuracy in two different increments, 0.2 Pounds in product details and 0.2lb/0.05kg in the feature text, and gives capacity as 400 Pounds while the title says 400lbs. Rechargeable power is listed alongside a required included Lithium Metal battery, and the stated weight appears both as 1.2 Kilograms and within the dimensions entry. Confirm the selected listing’s applicable measurement and battery details. The claimed battery duration depends on a full charge.

Who is it for?

A good fit for

Adults wanting body-weight and body-composition tracking with app history.
Households that want one scale with separate user profiles and trend charts.
People who prefer USB-rechargeable power and can charge the built-in battery.

Does the scale need a phone nearby?

No. The listing says it can record a measurement without a nearby phone and sync the data to the app after reconnecting.

How does the listed battery work?
