That's wrong, if they only specifiy Ah, then they usually imply cell voltage (3.7V avg.) and not the 5V you're drawing over USB.
Even if you assume you're charging a phone with that, you first need to subtract 25-40% total losses. And then consider that phone batteries are LiHV with 3.85-3.9V nowadays.
