Samsung Galaxy Fit 3 SM-R390 charging cable

This two-pack supplies replacement USB-A magnetic cables built for the Samsung Galaxy Fit 3 SM-R390 fitness tracker released in 2024. Each cable snaps on with a strong magnet that aligns the charging contacts automatically. The 3.3 ft length suits desk or bedside charging without excess slack.

USB-A 5 V 0.5 A power limit

The cable draws 5 V at 0.5 A from any standard USB-A port on a computer, power bank or wall adapter rated under 2 A. A built-in voltage regulator protects the tracker from over-current damage. Fast-charging adapters must be avoided because they exceed the specified input.

One-hour full charge cycle

A depleted Galaxy Fit 3 reaches full capacity in roughly one hour, giving a week of typical tracking per session. The twin cables let you keep one at a desk and one in a bag so the tracker is never left without a charger. No smartwatch is included in the pack.

Questions about this item

Should I buy the single cable or the two-pack for my Galaxy Fit 3 SM-R390?

The listing supplies two magnetic charging cables so you have a spare for travel or a second desk without ordering again.

What does the one-hour charge time mean when I plug this into my laptop USB port?

The cable delivers 5 V at 0.5 A, so a laptop port will fully charge the Galaxy Fit 3 in roughly one hour.

Does the USB-A connector limit charging speed compared with a USB-C cable?

The built-in IC caps input at 5 V/0.5 A, so the USB-A interface already matches the cable’s maximum rate.
