The Anker Nano Power Bank offers 10,000mAh of capacity and a built-in retractable USB-C cable. For Prime Day, it's at its lowest price of the year.

The Anker Nano Power Bank is our favorite portable battery for travel, commuting, and long days away from an outlet. At full price, it's already an excellent buy, but for Prime Day, it's even easier to recommend. Right now, you can grab it for 30% off, making it a smart time to snag one before your next trip. It's one of the top Prime Day deals we've found so far.

This isn't the kind of backup battery that feels like a chore to carry. It has a 10,000mAh capacity, an integrated display, supports up to 45W charging, and includes a retractable USB-C cable, so you don't have to remember to pack a separate cord.

Our reviewer called the Anker Nano Power Bank his go-to travel charger because it offers a useful mix of power, portability, and convenience. It usually retails for $59, but it's $42 for Prime Day, which is just a tad over its all-time low of $40 from last December. This is an especially appealing buy for anyone who wants a simple way to keep their phone, tablet, or laptop topped up on the go.

  • It's got solid capacity: The 10,000mAh battery can provide about two extra charges for an iPhone 17 Pro, according to our reviewer's testing.
  • The built-in USB-C cable is a huge convenience: Since the cord retracts into the power bank, there's no loose cable to misplace, untangle, or remember to pack.
  • It gives you more ways to plug in: In addition to the built-in USB-C cable, it has a USB-C port and a USB-A port for charging with other cables or powering multiple devices.
  • The screen is genuinely useful: The display shows the remaining battery, how much power a connected device is drawing, and how long the power bank will take to recharge.
  • It supports pass-through charging: You can recharge the power bank while it's also charging your phone, which is especially handy in a hotel room or anywhere outlets are limited.
  • It's easy to pack: It isn't tiny enough for every pocket, but it fits well in bags, purses, and many jackets, making it a practical everyday travel companion.
