What power adapter do I need for my Raspberry Pi Zero?

Question

Batteries

Hello guys, Pi Zero W came to me, now I order everything additional that I need in local stores. And stuck on the issue of choosing a power adapter. There are options with 5v 1a and 5v 2a .
Actually, my question may be a little silly, but if I connect a bunch of all sorts of sensors, usb (for example, a keyboard + mouse), hdmi, to the raspberry, will I have enough 1 ampere on the power supply? Thank you.

Answer 1

If you connect all sorts of sensors, then there may not be enough power. Take on 2A just in case. Yes, and the power supplies themselves may not give honest amps. Looked through the search. I understand that the power is supplied via microUSB, then you have a large choice for the device. Chargers for smartphones and tablets will fit for such tasks. The main thing is to look at the maximum current. If they are not enough, then take more powerfully.
