I’ve discovered that there are plenty of ways I can charge my Prevention Circul+. So, even though charging my ring using a wall adapter is a good option, I don’t have to depend on it.

I have found out that charging my Circul+ with a laptop USB is much more convenient– especially during the times I am on the go and don’t have a wall adapter nearby. However, not gonna lie, it took me a couple of tries to get the hang of this method.

In fact, this method has made charging my Prevention Circul+ so easy that I think everyone should try it out, too. So, keep reading this article till the end, and I will tell you how it can be done.

Steps To Charge Prevention Circul+ With Laptop#

Step 1: Gather Things Needed#

To charge my Circul+ ring, I only need that little USB charging platform that comes along with it, a laptop with a type-A USB port, and, of course, my Circul+ ring.

Note: My friend Smriti, who also uses a Circul+ ring, has a laptop that only has a Type-C USB port. This is why she first has to attach a USB-C to USB-A adapter to her laptop and then connect the charging platform of the ring to it.

Step 2: Connect The Ring & USB Port#

Once I have gathered the things needed, I just have to make a few quick connections to get my ring to start charging. This implies that I have to fit the charging connectors of the ring to the USB port.

My Circul+ ring isn’t quite similar in design to other rings. The lower portion of it is fairly flat and contains all the sensors that my ring needs to collect data. This part also contains two narrow gold connectors that are needed to charge my ring.

Circul+ comes with a short USB-C platform that is used to charge it. So, I take the USB charging thing and insert the ring into it. I do it in a way that the connectors at the underside of the ring get attached to the magnets on the charging platform. The two gently click into the correct position; I don’t have to use unnecessary force.

Step 3: Check For A Green Light#

When I am successful in getting the ring and the USB port to connect, a green light starts blinking within a few seconds. However, during the times my ring was deeply discharged, it took up to 5 minutes for the ring to start blinking.

Furthermore, while going through the official Prevention Circul+ website, I found out that it can even take up to 20 minutes for the ring to start blinking. I wrote to Circul+ seeking clarification on the matter, but I am still awaiting their reply.

If You Don’t See A Green Light

There were times when I didn’t get to see a green light despite thinking I had done everything right. In such cases, I waited for a few minutes and then tried out any (sometimes all) of the below-mentioned troubleshooting methods:

  • Recheck the alignment: Getting the USB port and the ring to align correctly can be tricky business– especially in the beginning.
    • So, I recheck the positioning and try fitting them together again. This doesn’t mean that I force the ring to fit (since there are magnets, I don’t have to use force at all); I just realign them.
  • Charge the laptop: While I have gone on and on about how convenient the laptop method is, I need to tell you that I couldn’t charge my rings via my laptop during the days the latter was low on battery.
    • This means the laptop needs to have sufficient battery itself to support charging another device.
    • `The solution? I would plug in my laptop, let it charge up for a bit, and then connect my ring.
  • Clean the ring connectors and USB port: Sometimes, after a bit of gardening, I have had trouble getting my Circul+ to charge. This has been because of the debris or dust that settled on the charging contacts, which makes it difficult for them to connect.
    • In such cases, I simply took a Q-tip and cleaned the contact points with it. And as expected, after a thorough cleaning, my ring started to charge properly.

Step 4: Wait#

The charging time depends on how depleted my ring’s battery is. However, generally, it takes about 2 hours for my Circul+ ring to fully charge. When this happens, the blinking green light gets replaced by a solid green light to indicate the same. It also serves as a cue to get the ring off charge so that the battery charged isn’t lost when emitting the green light.

Frequently Asked Questions#

01Can I Charge My Circul+ with A Power Bank?

Yes, you can charge your Circul+ with a power bank with a USB port.

02What if I Have Lost My Circul+ Charging Cradle?

If you’ve lost your Circul+ charging cradle, you can purchase a replacement from the BodiMetrics website for $16.99. However, please note that you will have to order a minimum of 2 chargers.

03How Long Does It Take to Charge My Circul+ Ring?

The charging time depends on some factors like the power source and the battery level of the ring at which you’re putting it to charge. But, to give you a general overview, it can take up to 1-2 hours for the ring to fully charge.

Wrap Up#

Phew! So, that’s how I charge my Prevention Circul+ ring! Putting any device to charge is a pretty simple thing to do. But that was not the case for me when I got my Circul+ ring. However, after all these months of using the ring, connecting it to the USB charging platform, and ensuring that the two have indeed connected properly, it doesn’t seem like a big deal to me.

But how do you feel about the whole process? Follow the steps mentioned above, and then come back to let me know!
