Quick noob question about powering with batteries

Would this be safe to hook up directly to GPIO pins? https://www.lazada.com.ph/products/18650-lithium-battery-charge-shield-board-type-a-usb-3a5v-3v1a-micro-usb-for-arduino-raspberry-pi-nodemcu-i4323633966-s24278671844.html?

Its current rating is 2.2 Amp witch makes it a usable for Raspberry Pi 3 (if you don't add a lot of power consuming HATs or USB devices) and older. See below link for more info. https://discord.com/channels/818384379197784084/1196069993331310702

and its safe for the raspberry pi 2 zero W?

it wouldn't run the risk of popping anything?

Regarding current, look at it this way. 1. You have consumers and they tries to consume the current they needs. 2. And then you have producers (Power supplies, batteries and such) that can deliver current to consumers. So if a consumer want more than a producer can deliver it is a NO go! But if a Consumer can deliver more than the consumer can consume it is not a problem, the over delivery will not be consumed.

the pi zero 2w uses 2 Amps and 5v (5 volts is the regular voltage for all pi's)

so yeah, it can handle it without frying it

It is over voltage that is frying the Pis

Ok

Thank you all so much for the help, I'm just worried of ruining my school project

You guys are amazing
