Sadly, there's only Galago Market near my country and even they aren't listed when specifying location in the shop.

So I can be 100% certain that a 4.5A battery won't do anything harmful to the Pi?

Hello, I want to be thorough before I actually do stuff to this bad boy because it's reasonably expensive for me and I don't want to fry it. I was wondering if a super charger from Huawei that outputs 5V, 3A or 4.5V, 5A or 5V, 4.5A will do the trick and won't long-term damage my Pi.
