Anker is a brand that has become synonymous with exemplary charging gear, and for good reason. Many of its wares feature on our list of best power banks for iPhone and Android thanks to their balance of top-quality features and affordable price, and the accessory maker is always quick to adopt new tech as it comes to market. A prime example of that is its MagGo Power Bank 6.6K, which features MagSafe and Qi2 tech, and is available for a rock-bottom $20 right now at Amazon.

Usually $70, this is a Black Friday deal you definitely don't want to miss, though there is a catch: It's only available to Amazon Prime subscribers. If that's you, you'll see the price reduced to $30 with a further $10 discount available via an on-page coupon.

Being Qi2-certified means that the Anker MagGo has 15-watt fast charging, offering twice the speed of a standard 7.5-watt wireless charger. The deal applies to the green and pink versions, though the black and blue options are just $5 more. It's specifically designed for recent iPhone models -- iPhone 12 or newer -- with an ergonomic design, as well as the option to double as a wireless charging stand.

As the name suggests, this device has a 6,600-mAh capacity which can fully recharge an iPhone. It also has a USB-C port for powering up wired devices, and you can use that port for passthrough charging to top up the power bank while wirelessly charging your phone, meaning it can function as a charging solution for your nightstand.

At $20, this is a total steal. Not only are you getting a power bank from a reputable brand, but you're getting one that is versatile and also incorporates the latest Qi2 charging tech. Running out of power when you're out and about is no fun, and this is a cheap way to solve that, whether it's for you or for someone on your holiday gift list. The only catch is that you have to be a Prime member which, let's face it, most of us are.
