Charger for Fitbit Versa 3/4 (Sonning RG4)

Just doing some tidying up and discovered this cable for my old Fitbit versa 3. I sold the device a while back but must have missed including this in the eBay listing. I believe this should fit Fitbit 3/4 and possibly a Sense 2 too. I think it works but can’t check this. Hope it is useful for someone!
