Rank #10 in Best Heart Rate Monitors 2026: 10 Ranked, Three Spec Sheets Wrong
FITCENT Rechargeable Heart Rate Monitor Chest Strap
Price and rating as shown on Amazon when we collected them. Both change.
The FITCENT CL820W is a rechargeable chest strap and it sits at number ten in this guide. It straps around your chest, picks up the electrical signal your heartbeat generates, and sends the reading over Bluetooth or ANT+ to a phone, a watch or a gym machine — the listing names Peloton, IFIT, DDP Yoga, Zwift, Polar, Garmin and Wahoo. FITCENT prices it at £45.99, and 187 Amazon customers have rated it 4.3 out of 5.
What makes this spec table worth reading is that two of its lines contradict the product described in the bullets. The sensor is labelled "Electrical", which is the straightforward description of a chest strap, but the same table lists a Display Size of 0.96 inches for a device with no screen anywhere in it, and a Battery Description of "Alkaline" for a unit the listing says is charged wirelessly. The listing also says a 1.5-hour charge covers an hour a day for up to 30 days. Everything on this page comes from the Amazon listing, not from our own testing of the strap.

What buyers actually say
Quoted from customer reviews on Amazon
Verified purchase“Arrived promptly. Well packaged. 'Feels' like good quality materials. Charged in less than an hour. Was seen by my polar app immediately and connected to Polar app with no problems. I also use a HR Monitor GmBH which also connected without problem. Each charge seems to last for over 10 hr's of monitoring. Can't speak for longevity as I've only been using it for a few weeks. Wireless charging works well.”
Verified purchase“i like this product , does what it is supposed to do , due to an illness i had to have a proper medical heart rate monitor affixed to me as well as using this at the same time and this one produced the same results , easy to charge and each charging cycle lasts about 90 mins a day for a good couple of weeks not the cheapest but does a good job”

Questions people ask
Is the FITCENT CL820W optical or electrical?
Electrical. Its spec table says "Sensor Type: Electrical", and the first bullet explains that the micro voltage signal from the heartbeat is amplified directly rather than read by optical sensors and converted by software.
Does the FITCENT CL820W have a screen?
No bullet describes one. The FITCENT CL820W is a chest strap that transmits your heart rate to a phone or gym machine, yet its spec table lists a Display Size of 0.96 inches.
How long does the battery last?
The listing says a 1.5-hour charge gives you an hour a day for up to 30 days, which works out at roughly 30 hours of use. The spec table's Battery Average Life is also given as 30 days.
How is the FITCENT CL820W charged?
On the wireless dock included in the box, according to the listing. The spec table's "Battery Description: Alkaline" does not match a wirelessly rechargeable unit.
What can the FITCENT CL820W connect to?
The listing gives Bluetooth 5.0 and ANT+, and the title names Peloton, IFIT, DDP Yoga, Zwift, Polar, Garmin and Wahoo. The spec table's Compatible Devices line says Smartphones only.
Is the FITCENT CL820W waterproof?
The listing gives it IP68 and says it can be submerged up to 10 metres, and that it keeps working in rain and sweat.
