Fitness Sensors and Devices Supported By Charged

Charged reads battery details from the activity files your bike computer or watch records, and directly from Bluetooth sensors with Quick Scan. Every device below has reported battery level or status to Charged on a real activity or scan. This is a list of what works, from actual rides and runs.

Today, that list includes more than 130 models from more than 30 brands. If your device isn't listed yet, it may already work or be added soon.

How to read this list

Battery Level
devices report a battery percentage, or a voltage Charged converts to one.
OK / Low
devices report a word like OK, New, Low or Critical instead of a number. Charged alerts you when they drop to Low.
Synced Activities
are read from activity files synced through your linked account.
Quick Scan
reads sensors directly over Bluetooth in the app.
Confirms Charged has read a device that way. Blanks may not have been tried yet.
×
Confirmed Charged is not able to report battery details for this device/this way.

What a device reports can depend on the bike computer or watch that recorded the activity. Some models send a percentage over Bluetooth but only a status from synced activities. Quick Scan can fill in the number in those cases. More in the FAQ.

Don't see your device?

Charged adds support for new devices constantly. Try uploading a FIT file if you have one handy, to check if your sensors are already supported. For Bluetooth sensors, run a Quick Scan in the app.

When we are certain a sensor cannot be reported by Charged, we'll note that. Today, the list is a single device: Garmin HRM3-SS (2011).

A few bike computers and watches record activities but leave their own battery, or their sensors' batteries, out of the file. The FAQ lists the ones we know about.

Get Charged and get a Heads Up

After linking your Garmin Connect™, Hammerhead, Intervals.icu, or Wahoo Fitness account, Charged checks every paired sensor after each ride or run and alerts you when one runs low.

Get the app   or open Charged in your browser.
