So it's arrived and rated one of the best fitness trackers on the market, we take a look at the Charge's evolution and help you decide which model suits you!
The obvious improvements are in the size of the screen and the increasing functionality. One constant in the Fitbit Charge is the release price - $130 for the latest model.
The Fitbit Charge - original
Released all the way back in 2014, the basic model tracks step, sleep, flights of stairs and distance.
Hot on the heals of the Charge 1 was the Charge HR.
You can still buy this model for around £25, however, we do not stock the replacement straps for this particular Charge model.
The Fitbit Charge 2
The next generation fitness tracker, looking more like the models of today, sporting a larger screen and multisport mode, enabling users to track a variety of activities. Only water resitant, the Charge 2 was not able to monitor swimming activity.
We have some great colours and style replacement wriststraps, from sophisticated stainless steel, to fun, bold patterns.
The Fitbit Charge 3
Heart rate sensor, oxygen saturation sensor which is not yet operational and an improved sleep tracker.
The Charge 3 had one big improvement, waterproof to 50m, this meant the monitor could now be used whilst swimming.
Apps are not available on the wristband, and the Charge 3 was only able to use GPS and Fitbit Pay via a smartphone.
