Anker 621 Magnetic Battery (MagGo) review
The Anker 621 Magnetic Battery is one of the simpler wireless power banks that Anker makes. It offers a 5,000mAh capacity and up to 12W of total power output. It also features a MagSafe charging pad for the iPhone 12 series and beyond, which offers up to 7.5W of charging power, as well as a USB-C port for wired charging.
The MagSafe area is slightly padded with a PU leatherette that feels durable. It showed no signs of wear during our tests, as some other soft-touch charging pads have.
The Anker 621 MagGo has a simple, clean look with soft edges. The two-tone pale blue color scheme also adds an element of vibrancy missing from many other of the best power banks, and other variants are available, including white, green, and purple. This makes the 621 a good match for the stylish designs of the best iPhones.
The only interface is a charging and battery life indicator, represented by small LED dots that are easy to comprehend. There are four dots indicating the battery life of the 621, and a singular dot that flashes to indicate charging activity.
One of the standout aspects of the Anker 621 is its form: it’s impressively thin and light, making it great to travel with and it’s much easier to use your iPhone while it’s attached, compared to other, heavier MagSafe power banks.
However, the price you pay for this portability is the reduced capacity, as the Anker 621 is only rated at 5,000mAh. During our tests, it managed to charge an iPhone 13 Pro in about two hours, reducing the power bank’s battery indicator to two LED dots, indicating a battery level between 25%-50%.
When using the USB-C port for wired charging, the 621 charged a Pixel 7a from half to full in just over an hour, again losing between 50-75% of battery life in the process. Charging the bank itself took about 2 hours and 40 minutes, which is a reasonable speed for a bank of this size.
If you’re looking for a power bank that lets you easily use and charge your iPhone at the same time, then the 621 could be ideal, given how thin and light it is. The vibrant colorways also make it an accessory you’d be happy to flaunt alongside your device.
