How many times can it charge a phone?

About once for a typical iPhone or Android phone. Larger phones with big batteries may get less than a full charge.

Does it support fast charging?

No. Total output is 12W across both ports, so it charges slowly compared with Power Delivery packs.

What comes in the box?

The power bank, a 2 ft (0.6 m) USB-A to USB-C cable and a welcome guide. A wall charger is not included.

Can it charge two devices at once?

Yes, through the USB-C and USB-A ports, but the 12W is split between them, so each device charges more slowly.

Is it allowed on a plane?

Yes. At 5,000mAh it is well under the 100Wh carry-on limit most airlines use.

How do I check the battery level?

Press the button and the LED indicators show the remaining charge.

Our take on the Anker 5,000mAh (5K) Power Bank

The Anker 321 Power Bank (PowerCore 5K) is a pocket-sized 5,000mAh battery with one USB-C port and one USB-A port. It charges two devices at once at a combined 12W, which is slow by current standards. It is built for a top-up on a commute or a night out, not for fast-charging a modern phone. Against larger 10,000mAh packs it trades capacity for size and weight; against slim MagSafe-style packs it offers a cable connection instead of magnetic snap-on. Owners rate it well for portability and reliability.
