G4Pro PLC Controller: Advanced Industrial Automation Solution
On this page
What is the G4Pro?
The G4Pro on this delivery record is a Theragun TG-FC-50 battery charger — the mains-side charger Theragun supplies for the G3PRO percussion massager, not a PLC controller as the listing title suggests. The charger itself settles the question: the underside is moulded THERAGUN BATTERY CHARGER, Model TG-FC-50, and the compatibility line reads "Compatible with: Theragun G3PRO". This unit is new with its factory plastic wrap still on, serial SN 202400121, intake recorded 27 October 2025, record weight 0.5 kg. The five photos below show this exact charger from every side, including the full rating label.

Why this charger, and what the label commits to
The G3PRO charges its battery through a desk cradle rather than a port on the body, and the TG-FC-50 is that cradle: the massager's battery handle drops into the well, seats on two contact pins, and the white strip under the well reports charge state. The label keeps the numbers plain — 20 V DC in, 16.4 V DC out at 3.0 A — and 16.4 V is the standard full-charge voltage for a 4-cell lithium-ion pack, which is what the G3PRO's removable battery runs. The caution block is equally specific: dry location, indoor use only, and 16.4 V Li-ion packs only, because a charger matched to one cell count is not interchangeable with others.
For a G3PRO owner the failure mode is usually the cradle, not the battery — lost in a move, left behind in a clinic, or a pin damaged by a bad drop. A sealed replacement with the original labelling restores the charging dock without touching the massager itself. The unit photographed here is factory-new with the wrap still on: the wordmark crisp, the LED strip unscratched, the four rubber feet clean. Anyone running multiple G3PRO batteries can also keep a second cradle at the charge station so one pack charges while the other is in use.
