There’s no such thing as having too much battery life, and we’ve spotted several fantastic USB battery pack deals, including a pair or Aukey chargers for $5, and one of Anker’s new PowerCore models (which would be suitable for charging a USB-C MacBook) for $23.

Note: The aluminum Aukey charger is significantly smaller than the plastic 10,000mAh one, but it ships free with Prime, while the larger one is an add-on item. There are <cough> ways to get around that restriction, however.
