Tom Tom 12 volt car chargers

[XXL540 S OWNER]

I just bought a second car charger. The box states that it is for the One XL. The One XL uses a 3.7 volt internal battery (according to a battery vendor). The output on the lighter charger is .5 volt @ 1.2 amps. Is this charger correct for a 3.7 volt unit? Will the charger work on my XXL 540-S?

All TomTom car chargers output 5 volts and the devices contain a 3,7 volt battery don't worry about it the device contains the necessary circuits to control the battery charge while connected to the vehicles supply - Mike
