What is the best portable power bank?

In a world increasingly driven by technology, easy access to extra smart phone power as and when you need it is critical. You could be stuck in a blackout, or need the GPS on your device urgently to help you find your way. While standard power banks can be great in an urban environment, if you can't get access to a charging point they're just a useless hunk of junk for you to carry around. The best portable power banks incorporate the ability to charge from sunlight into the battery pack, allowing you to still charge your devices even on camping trips and other out-of-the-way locales. They can be an invaluable investment in safety and comfort. Do be aware that the solar recharge function is usually built in to be secondary to a normal charging function, not to be used as the primary function.
