A:AnswerIt doesn't come with a charger it does come with a wire that plugs into your 12V socket in the car. If you want to charge it at home you can your any power adapter you have and the appropriate cord for the unit and it will charge. I find it's best to just use the power cable int he car and if I do need to take it with me for hiking or such It will be ready to go. To use internal power while mounted int he car isn't the best thing to do in my opinion. Hope that helps.
