Grab an Anker PowerCore Slim 10,000mAh Power Bank for Only $13

If you're looking for a very inexpensive power bank from a reliable brand, then we've got a deal for you here. Amazon is offering an Anker PowerCore Slim 313 10,000mAh power bank for only $13.19 after an instant 40% off coupon code that you can clip on the product page. You'd be hard pressed to find a cheaper 10K capacity power bank from Amazon, and certainly not an Anker brand.

The Anker PowerCore Slim 313 is one of the slimmest 10,000mAh power banks around. It's almost the exact same dimensions as an iPhone 14 (only 0.2" thicker). There are three types of connections, but it's important to understand which is input and which is output. USB Type-C and Micro USB are INPUT only, which means that you use either of these ports to charge the power bank itself. USB Type-A is OUTPUT only, which means this is the port that you use to charge your other devices. It's capable of delivering up to 12W of charge using Anker's PowerIQ and VoltageBoost technologies.

A USB Type-A output is nice in that you can find cheap cable adapters for pretty much any connection, including Lightning and USB Type-C adapters. A 10K power bank will charge an iPhone 14 three times, an iPhone 14 Pro two times, an iPad or iPad Pro about one time, or a Nintendo Switch about two times. Since this power bank has no USB Power Delivery support, it won't be able to charge your Switch while you're playing a game, but you'd have to spend considerably more for that benefit.

Anker is probably the most trusted brand on Amazon when it comes to reliability and product quality. Usually that means Anker commands a higher price point, but this 10K power bank is inexpensive even compared to other "no-name" brands. If you're in need of cheap and universal battery backup, then this is a very safe bet.
