Anker is preparing to release its largest portable charger with no AC outlets... Take a look at 347 PowerCore 40K!

On the other hand, the mAh is important to be able to figure out how many charges you will be carrying with the power bank. Each power bank has its battery capacity listed in the specs. The higher the number, the more juice it can store. For example, a more unassuming option (like the 5,000mAh Anker 511) will be able to charge your phone completely just once or one and a half times, depending on your phone's battery capacity, while big solutions (like 24,000mAh ones) will offer several charges, needed for people with a more busy schedule and more time outside (and heavier phone use when out!).

Also, Anker is the official portable charger brand for the Nintendo Switch. It has two products that are specifically optimized for the portable console in its PowerCore 13400 Nintendo Switch Edition and the larger 20100 Edition too.

High Capacity Hero: The super huge 40,000mAh cell capacity is large enough to fully charge an iPhone 13 over 8 times, a Samsung Galaxy S22 Ultra over 6 times, and a 2020 MacBook Air over 2 times. That's a bit of a jump up for the Anker product, but generally it's worth paying that to have a power bank from a more trusted brand.

High-Speed Charging: 30W USB-C charging gives you the power you need to charge up your iPhone 13 to 53% in just 28 minutes.

Wide Compatibility: Supports Power Delivery charging technology and works flawlessly with a wide range of devices such as laptops, phones, tablets, and more. Stay protected while you charge thanks to Anker’s exclusive MultiProtect safety technology and Negative Temperature Coefficient (NTC) sensors for precise temperature monitoring Power banks are not sexy. Design-wise, they're roughly as interesting as TV remotes or tin openers. But you need one. You may need two. And you need them to be decent, or one of these days you're going to find yourself on one percent, beached, trying desperately to find a crumb of charge somewhere. Ports: Different devices have different charging ports, and your power bank should be compatible with them. Look for power banks with the right ports, such as Lightning or USB-C, to ensure seamless charging for all your devices. Having multiple ports is a bonus, allowing you to charge multiple gadgets simultaneously. Read the Instructions: Take a few minutes to read the user manual that comes with your power bank. Familiarize yourself with its features, usage instructions, and safety precautions. This will help you make the most of your new gadget while keeping yourself and your devices safe.

You can always buy an extra cable to charge up your power bank, but we just find it useful to only have one type of cable, so if your phone supports USB-C charging you'll likely want to find a power bank that supports the same. It's also worth noting how the power bank itself is charged up. Some devices from Anker still support micro USB, while others use USB-C. At the moment, no Anker power banks can be charged up with a Lightning cable.

Anker's power banks generally do what they aim to with relatively little extra. For example, the brand doesn't have any power banks that also support wireless charging or any other exciting features. Power for 4: Equipped with 2 USB-A and 2 USB-C ports, the portable charger is ideal for charging your laptop, phone, tablet, and earphones.

Do Anker power banks work with both Android and iPhone devices?

Charge it Fully: Plug in your power bank and let it charge fully before using it. This ensures that it's ready to provide a reliable power source when you need it.
