Amazon currently has a great deal on AUKEY's 26,500mAh USB-C power bank. It is currently priced at $77, but with the promo code AUKEYPD7, you can pick it up for just $56. Making it an incredible buy, and one of the cheapest battery packs with USB-C PD.
This battery pack from AUKEY is a pretty special one. It's a USB-C battery pack, but that USB-C port does also do Power Delivery or PD. What this means is that it is able to charge larger gadgets like a laptop or a Nintendo Switch with this port. Gadgets that would need more output than most battery packs can provide. But this one does provide it. Making it much more versatile. Additionally, this does also have Quick Charge 3.0 support available as well. So you can quickly charge up devices that are supported, without being tied to the wall.
This item is also eligible for Amazon Prime's free shipping. Which includes free two-day shipping, and pretty cheap next-day shipping if you need it here extra fast.
