You never know how useful a portable battery charger really is until you actually need one. Whether you're going on a camping trip, stuck in the middle of a power outage, or simply trying to escape a Low Battery warning on your phone while you're away from home for the day, keeping a portable charger around lets you recharge no matter where you are.

There are tons of cheap portable battery packs out there, but those options generally don't last very long. They simply have small capacities so they run out of juice quicker. If you want a portable charger that won't run out of power so quickly, you'll want to pick up a large-capacity power bank instead. While options with 10000mAh capacity are great for daily use with your smartphone or tablet, there are picks with double that capacity or more so you can power up a laptop or just generally have more power stored for later use.

Not too worried about what's on sale? Our guide to the best portable chargers & power banks has even more options worth considering though it does include smaller-capacity products as well.
