Fitbit Charge 2: Specifications, Features & Price


The Fitbit Charge 2 is a multifunctional wristband that comes with an accelerometer and optical heart rate monitor, with its pedometer being one of the most accurate models available on the market. However, the wristband is not made from waterproof materials and therefore is not suitable for swimming or aquatic activities.

Fitbit Charge 2_ Specifications, Features Price

In terms of its functions, the wristband offers some of the most accurate readings on the market, although the expensive price may deter potential customers. Despite its numerous features, the product does not meet the usual standards of a smartwatch, as the wristband does not feature a built-in GPS system or microphone headset.

In contrast, the second generation utilizes Fitbit Charge HR and offers more features than its predecessor. So you may want to consider upgrading the device.

In terms of its design, the Fitbit Charge 2 remains similar to the Fitbit Charge HR in that the watch takes the form of a rectangular device that is connected on two sides by the main wristband.

The straps can be easily removed and will rarely detach by themselves. When wearing the Fitbit, you will need to adjust the wristband until it rests against your pulse without causing harm or discomfort.

However, there are some notable differences between this model and its predecessors, as the display now fills the case and the straps are much thicker. On one side of the device, you will find a physical button that will allow you to browse screens, change information (i.e. steps, pulse, calories) and alter training modes.

The device is incredibly convenient, although there is a slight protrusion on the back, which belongs to the heart rate monitor. While the straps are much thicker in their design, they are also uncomfortable when compared to the Fitbit Charge HR, which means you will have to get used to them over time.

Another setback comes in the form of the screen, which can activate due to small movements in your sleep.

When purchasing a Fitbit Charge 2 from the official website, you will be given the option of silicone or leather straps, although the latter will cost an additional sum of money.

Silicone straps are available in shades of black, blue, turquoise, grey and green, while leather straps favour darker tones such as black and brown. While the overall design is very simple, it does not stand out when compared to more complex alternatives.


  • The device offers automatic tracking for training with switchover, which allows you to pause between exercise routines.
  • Along with the traditional features, the Fitbit Charge 2 also comes with a training diary and the function to set motivational tasks.
  • The wristband can be used to access social networks, allowing you to communicate with your friends and family.
  • The Fitbit will measure the number of steps you have taken, while tracking the distance that you have covered.
  • While the device can record distance and heart rate, it can also be used to determine the height of staircases and steps.
  • When running or working out, the Fitbit will constantly work to measure your pulse and heart rate.
  • The Fitbit Charge 2 is capable of analyzing your sleep time and phases, which can help you to organize your sleep patterns.
  • The wristband is capable of calculating the calories burned off during exercise and throughout the day.
  • You will receive notifications during periods of inactivity that will remind you to keep exercising.
  • The device can be used to determine the maximum amount of oxygen consumed in a single day.


The Fitbit Charge 2 is essentially a modified version of the Fitbit Charge HR, which means it shares the same features as its predecessor and works to improve upon them. You can find a list of the product’s pros in the following section:

  • Accurate Sensors: in contrast to the Fitbit Charge HR, the Fitbit Charge 2 features a heart rate monitor and pedometer with state of the art sensors, which helps to produce more accurate readings.
  • Bright Display: the device comes with a large and bright display, which makes it easier to read your calculations and data.
  • Sleep Monitor: the wristband offers accurate sleep monitoring that can be used to identify sleep time and patterns.
  • Daily Reminders: the Fitbit Charge 2 will notify you of your progress and will alert you during moments of inactivity.
  • Training Mode: the device can be worn for a wide range of sports and activities, offering training modes for beginners.


Unfortunately, the Fitbit Charge 2 does come with some negative setbacks, which we have outlined in the list below:

  • Fictional Results: when the device has been taken off, it can sometimes still register activity without being connected to a pulse.
  • Water Resistance: the Fitbit Charge 2 does not feature any water protection, which makes it unusable for swimmers.
  • Short Battery Life: when the wristband has been fully charged, it can work without recharging for a total of 5 days.
  • Substandard Charge: the charger does not feature any magnet technology and does not connect well to the wristband.
  • Heavy Design: the watch weighs around 35 grams, which can make it heavy and uncomfortable to wear during routines.
  • Lack of Notifications: the Fitbit will only deliver notifications after it has been connected to your smartphone, although they are not stored in the device’s memory.


The Fitbit Charge 2 has one of the best applications among all fitness trackers, as it offers a range of special features and is very simple to use. If you have previously owned a Fitbit, then you will be able to operate this model without issue. The wristband itself is also compatible with Android and iOS devices, which can be located via Bluetooth.


These days, the Fitbit Charge 2 can be purchased online for around $189.99, although it is possible to find cheaper prices on platforms such as Amazon and Ebay.
