For $20, it's hard to beat this Anker power bank for portability and performance.

Some tech devices are so cheap that it's hard to imagine them becoming more affordable. But that's exactly what happened to the Anker PowerCore 10K, which is on sale on Amazon for $19.99 (was $25.99).

Frankly, this is a ridiculous price for a power bank with a 10,000 mAh capacity, and although we haven't reviewed this particular model, Anker is always very well represented in our guide to the best power banks.

Today's best cheap power bank deal

We haven't reviewed the PowerCore 10K, but on paper, it's one of the thinnest and lightest 10,000 mAh portable chargers on the market. If you find yourself in a tough situation, it will increase the load on a laptop, but in reality, it is primarily designed to keep your phone running, whether you're out and about, traveling, or camping.

In terms of connectivity, the PowerCore 10K includes a dedicated micro USB port for charging the power bank, a USB-C port that supports input and output, and an output-only USB-A port. As a result, you can charge two devices at once if you wish.

We've reviewed a ton of power banks, and if this one isn't for you, we highly recommend the Anker MagGo Power Bank (10K Slim), Anker 737 Power Bank (PowerCore 24K), or Anker 20,000mAh 87W Power Bank. Our reviews are detailed and cover all the pros and cons.
