⌚🔌 Fitbit USB Charging Adapter • 5V Power Cable
 
(USB Type‑A to Proprietary Dock/Clip • Model‑Specific Variants)

Fitbit trackers and watches all charge via USB Type‑A, but the device‑side connector varies widely. Below are the definitive connector categories and their associated models.
 
🟦 Capsule Dock (Insert Style)
Fitbit Flex → capsule slides into a small USB dock
Fitbit Flex 2 → slimmer capsule dock, not interchangeable with original Flex
Use case: Capsule removed from band and inserted into dock.
Note: Flex and Flex 2 docks are not cross‑compatible.
 
🟦 Clip‑Style Cradle (Early 2‑pin / 3‑pin)
Fitbit Charge (1st gen) → 2‑pin clip cradle
Fitbit Charge HR → 3‑pin clip cradle
Fitbit Surge → wide clip cradle with 3 pogo pins
Fitbit Alta / Fitbit Ace (kids) → spring‑loaded clip cradle with 3 pogo pins
Fitbit Alta HR → different clip cradle, not interchangeable with Alta/Ace
Use case: Tracker body clips into cradle; pogo pins align with charging contacts.
Note: Each cradle is model‑specific — Alta ≠ Alta HR.
 
🟦 Wide Spring‑Loaded Cradle (4‑pin)
Fitbit Charge 2
Use case: Larger clamp‑style cradle that grips the tracker body.
Note: Unique to Charge 2 — not compatible with earlier or later Charges.
 
🟦 Slim Clip Cradle (Shared Design)
Fitbit Charge 3
Fitbit Charge 4

Fitbit Luxe
Fitbit Ionic (earlier magnetic dock, unique — not cross‑compatible with Charge 5/6/Luxe)
Fitbit Versa 3 / Versa 4
Fitbit Sense / Sense 2
Use case: Magnetic alignment with pogo pins; no clip required.
Note: Charge 5/6 and Luxe share one dock. Versa 3/4 and Sense/Sense 2 share another dock. Ionic is separate.
 
🟦 Versa Clip Cradles (Legacy Split)
Fitbit Versa (1st gen) & Versa Lite → same clip cradle
Fitbit Versa 2 → different clip cradle, not compatible with Versa 1/Lite
