The male jack of my Neo 2T power supply is damaged (because it sticks out of the back of the machine in a way that makes it very easy to knock when walking past). Garmin's own replacement power supply is an absolute rip-off, priced at £63 (UK pounds).
The power supply is a 48V 0.84A one, with the ID GSM40B48-P1LTE. Various online sources have similar PS units available for around a third of the price, with the ID GSM40B48-P1J, e.g. https://www.powersuppliesonline.co.uk/power-adapters/gsm40a48-p1j-40w-48v-0-84a-power-adapter.html
I'm wondering if this will work. It's exactly the same power spec. so my only worry would be whether the jack is the same or functionally the same. I've a feeling that the P1J / P1LTE bit may refer to the jack type, although they look identical in pictures.
