The 10 Best Portable Phone Chargers

The Jackery Bar makes a great addition to any travel kit, as it comes in a size that's small enough to fit easily into a pocket and even features a built-in LED light for finding your way in the dark. It's not the most powerful option out there, but it is very convenient.

Anyone looking for a compromise between size and milliamp hours should consider the RavPower 22000. Its ergonomically-curved chassis makes it appear much smaller than it actually is, especially in the palm of your hand, though it still manages to hold plenty of juice.

Ideal for users of the company's phones, but good for anyone with a quick-charging device, the Samsung Fast Charge is supposed to be able to bring your battery up to 50 percent in 30 minutes. That can feel like a godsend when you're on-the-go or in an emergency situation.

WIth a sizeable 30000mAh capacity, the Aukey Quick Charge 3.0 is capable of reviving your phone several times over, or even a tablet a few times, before going dead itself. Its wealth of cable ports, including mini-USB and Lightning, make it a pretty versatile option, too.

The unique thing about the Goal Zero Flip 20 is that it has an articulated USB flip tip for wall charging, which cuts down on the amount of cable you need to carry around. That can be a little awkward in some situations, but it's a feature not many other models offer.

The Mophie Space Grey has just about everything you'd want in a mid-size power bank, including two ports, a pass-through charging mode, and a low-profile design that looks great sitting on a table at your local coffee shop. Unfortunately, it comes at a pretty steep cost.

Coming in a package that's not much bigger than a lipstick, the Anker PowerCore 5000 is hands-down one of the most portable options available. Don't let it's puny size fool you, though: at 5,000 mAh, this model packs an impressive punch.

Perfect for Android users, the Tronsmart Presto comes packed with tons of advanced features, including a high 20,000 mAh capacity, the ability to accommodate three devices at once, and both Quick Charge 3.0 and USB-C ports. At this price, it's also a great value.

Few portable chargers make as good an everyday travel companion as the Jackery Bolt, which features both integrated micro-USB and Lightning connector cables, in case you forget yours, and is about the size of a bar of soap, so it never feels too cumbersome.

When you need a reliable and cost-effective solution, look no further than the Anker PowerCore II 10000. It has everything you need to keep multiple devices powered up throughout the day, all in a body that is much smaller than comparably powerful units.
