Some tech devices are so cheap that it’s hard to imagine them being 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).

That’s frankly a ridiculous price for a 10,000mAh capacity power bank, and while we haven’t reviewed this particular model, Anker is still 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 tight spot, this will add to the load on a laptop, but in reality it’s primarily designed to run your phone, whether that’s when you’re on the go, traveling, or camping.

In terms of connectivity, the PowerCore 10K includes a micro USB port exclusively for charging the power bank itself, a USB-C port supporting both input and output, and a USB-A port with output only. So you can charge two devices at once if you want.

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 the Anker 20,000 mAh 87W Power Bank. Our reviews are in-depth and cover all the pros and cons.
