RAVPower 15000mAh External Generation Portable Black
Amazon's catalog no longer lists this product (checked 2026-11-02). The name comes from the link HN users posted.
In my experience, those days when I need the extra bit of battery life are almost always at events, or while travelling. I can spot those days in advance, they're not surprises.
So I found a remarkably simple and obvious solution: I spent £50 and bought an external battery pack, something like http://www.amazon.co.uk/RAVPower-15000mAh-External-Generatio... . It charges overnight, weighs not all that much at the bottom of a shoulder bag, but on those crucial days when battery is getting slim, I can just pull a cable out, plug it into my phone, and bingo: the phone is charged.
It's capable of charging an iPhone several times over so easily solves the problem for you and even some of your friends.
