I have just received the sonoff ihost and it isn’t include a ac power adapter, just de the cable.
It is needed a power suply of 5v and 2Amp, but in my house I have a lot of power adapters from mobiles and ipad about:
5v -2.1A (10w, from ipad)
quick charger with 5v - 2.4A / 5V - 3.5 A
Is it possible to use any of them, or I should buy and specific one?
