Almost fried my sat nav,
Verified Purchase(What is this?)
This review is from: Decrescent 2 Port Micro USB Car Charger for Apple iPod/iPhone/iPad - Black (Accessory)
The double USB car charger works fine but don't do what I did and leave your sat nav plugged in when you stop for petrol. Because when you restart the engine the extra Ampage shuts down the sat nav (I thought that I had lost the data and would have to replace it at a cost of over £100).
Luckily for me I managed to remove the cover on my sat nav and found a way to restart it.
