You can charge the headset and the Handlebar Remote by connecting the supplied USB power & data cable into a computer’s USB port or USB wall charger. You can use any standard micro USB cable to charge the units. The charging LEDs turn red while they are charging and turn blue when they are fully charged. It takes about 2.5 hours to be completely charged.
When charging the battery, use only the approved charger provided by the manufacturer. Use of a non-approved charger may cause fire, explosion, leakage, and other hazards which may also reduce the life time or performance of the battery.
Any 3rd party USB charger can be used with Sena products if the charger is approved by either the FCC, CE, IC or other locally approved agencies that Sena accepts.
Please make sure to take off your 10U-installed helmet while charging. The headset automatically turns off during charging.
