Excellent, you'll have no trouble using 3rd party adapters with those. The original adapter was rated at 7.5v and 2amps. If you think you might collect more, you might want to consider getting yourself a 7.5v/3amp power supply. The 165C and 180C need that extra amp for their colour screens, and you can use the higher amperage adapter with your 165 & 180 without any problems.
