The super slim 20,000 mAh power bank is now selling on eBay for just $10.45. This can charge a regular device by up to 8 times, saving you the constant trouble of running to the power outlet. Since the power bank is pretty slim, you can carry it around quite comfortably. One can’t deny the utility of having a power bank in their bag, especially considering what it brings to the table.
Elaborating on the hardware aspects of the power bank, well, it comes with two USB ports, allowing you to charge multiple devices simultaneously. This means that not only can you charge the smartphone when you’re out of juice, but also hook up your tablet. It’s a bit surprising to imagine a power bank of this size to carry that kind of power underneath, but we’re not complaining. It’s hard to see a device like this staying in stock for long, so make sure you snatch it up while it’s still available.
