Anker 523 Power Bank (PowerCore 10K)

The Ultra-Slim 20W Portable Charger

High-Speed Charging

The 20W USB-C port offers the kind of charging speed that you’d normally only find in a wall charger. Charge your iPhone 12 to 50% in just 30 minutes or charge a Samsung S20 in 1.5 hours.

Astonishing Size

PowerCore 10K successfully combines high cell capacity with remarkable portability. Only 0.6 inches thick and weighing just half a pound, you’ll barely notice it in your pocket.

Rapid Recharge

Power up your PowerCore 10K in just 5 hours with an 18W USB-C Power Delivery wall charger (not included). Recharging via a 10W USB-A charger and cable (not included) will take approximately 10 hours.

Superior Safety

Our MultiProtect safety system combines temperature control, short-circuit protection, and many more advanced safety features to give you peace of mind when charging.

Quality Throughout

With a sleek matte exterior and cool-blue LED light-wheel to display battery level, PowerCore 10K is both inside and out.

Notes:

  • 10,000mAh is the total nominal rated capacity of the internal battery cells.
  • The power bank is flight-approved and allowed on a plane.
  • Due to software issues, charging the iPhone 15 series is not ed at the moment.

The charging speed and functionality receive mixed reviews - while some say it charges quickly and works well with iPads and iPhones, others report it stops working. The reliability is also mixed, with some describing it as rock-solid while others find it unreliable. The charging ports and battery life get mixed , with some praising the USB-C charging capability and long use, while others report issues with the USB-C port not working with iPhones and the device shutting down after a few minutes of use.

    I had one of these for about 2 years before I had to replace it and I used it 5 days a week (I have 2 phones work and personal)
    This gave me a full charge on my phone about 3x before dying. Also fits right in my pocket if I wanted to use it on the go (if you dont mind a wire sticking out of your pocket)

    5.0 out of 5 stars Quick, Powerful, Lightweight Charger
    Reviewed in the United States on May 27, 2025
    Color: BlackVerified Purchase
    This is a great little charger. Once it's fully charged I was able to charge my iPhone 13 mini from 20-100% in a little over an hour and my wife's android from 30-90% in about 2 hours. It's thin and lightweight. We just returned from a 2 week cruise vacation where we were taking many, many photos a day with our phones and this charger was perfect for getting a quick charge near the end of the day.

    4.0 out of 5 stars Pocketable Power Bank That Actually Retains a Considerable Charge
    Reviewed in the United States on May 3, 2025
    Color: BlackVerified Purchase
    It's a great power bank. The charge lasts awhile even when constantly powering my Moto Razor+. I do, however, desire for one-fourth of the charge to last a full day of constant use since the power bank doesn't have any capabilities other than as a battery. I also wish that the bank were slightly smaller and more pocketable. If I could give this item n extra half star, I would.

    5.0 out of 5 stars Stay Powered Anywhere with the Anker Power Bank: A 10000mAh Portable Charger Review
    Reviewed in the United Kingdom on October 21, 2023
    Color: BlackVerified Purchase
    Anker has long been a trusted name in the world of portable chargers, and their 10000mAh USB-C Power Bank lives up to that reputation. This slim and sleek device is an absolute game-changer for anyone constantly on the move and in need of a reliable power source for their devices.

    The 10000mAh capacity might seem modest compared to some of the larger power banks on the market, but don't be deceived by its size. It provides ample power to charge your smartphone multiple times over or give your tablet a substantial boost. Plus, it's compact and lightweight, fitting easily into a pocket or bag without adding unnecessary bulk.

    The standout feature of this power bank is its 20W Power Delivery (PD) capability. It can charge your devices at impressive speeds, making it perfect for modern devices that fast charging. The USB-C PD port is versatile and can charge not only smartphones but also tablets, laptops, and other compatible gadgets.

    The build quality is excellent, as expected from Anker. It feels durable and well-constructed, and the matte finish adds a touch of elegance. The inclusion of a digital display to indicate the remaining battery capacity is a welcome addition, ensuring you're never left guessing.

    In conclusion, the Anker Power Bank with 10000mAh capacity and 20W Power Delivery is a must-have for individuals who require a reliable and fast-charging portable power source. It strikes the perfect balance between capacity, speed, and portability, making it an excellent investment for anyone on the move.
