How To Charge Whoop With Battery Pack?

How To Charge Whoop 4.0

Charging your Whoop 4.0 is pretty easy actually. Just slide your Whoop 4.0 battery pack onto your Whoop band until you hear a clicking sound.

Once you hear the clicking sound, it means that your Whoop battery pack is in the right place and is charging your Whoop band.

Can You Charge Whoop While Wearing It?

Whoop 4.0

Yes, you can charge your Whoop band while wearing it, irrespective of whether you have Whoop 4.0 or 3.0. That is the beauty of Whoop bands.

If you have Whoop 4.0 then you can even charge it while taking a shower. It means that you can take the Whoop battery pack 4.0 to the shower because the battery pack of Whoop 4.0 is water resistant.

However, if you have Whoop 3.0 then you should not wear its battery pack to the shower as it is not water resistant.

How Do I Know Whoop Is Charging?

If you have Whoop 4.0 then look for the small LED indication on the battery pack, it will tell you whether your Whoop band is getting charged or not. This light will be off by default, to see it you will have to double tap on the battery pack.

How To Check Whoop Battery Level?

After double tapping on the battery pack if the light is:

  • Solid Green (Not Blinking): It means that your Whoop band is charging and currently its charge is between 75% to 100%.
  • Blinking Green: It means that your band is charging and its battery percentage is between 25% and 74%.
  • Solid Red: It means that your band is getting charged but its battery level is in the range of 5% to 25%.
  • Blinking Red: It means that your band is charging but its battery percentage is less than 5%.

If you do not see any light on the Whoop battery pack then it means that your battery pack is out of charge itself.

How To Know Whoop Battery Pack Level?

You can check the battery level of your Whoop 4.0 battery pack by double tapping on it while it is not connected to your Whoop band. If you see:

  • Solid Green Light: It means that the battery percentage of the battery pack is between 90% to 100%.
  • Red Light: It means that your battery pack charge is less than or equal to 90%.

I think the red light kind of denotes the vague battery life because for me even 90% battery is good enough to charge my Whoop band. However, there is no way of knowing whether it is 90% charged or 1%. This becomes really irritating when you have to leave your home urgently and you do not know how much your battery pack will last.
