1 amp. The built in USB sockets at the front deliver 1 amp out. Sufficient for phones not for tablets. Thus if you are running a tablet or other device that needs 2 amps then you will get a net drain or it won't replenish. An adaptor may be required. Basically there are two 1 amp USB sockets in the front plus one 12 volt outlet. There are no other outlets. Wireless charging may be fitted or is an accessory. Some Ateca owners have added their own USB outlets in the rear housed behind the front centre arm rest adding 2amp for children in the rear with tablets plus a 12v outlet in the boot.
