October Prime Day may not officially kick off until Oct. 8, but that hasn't stopped Amazon from dropping some early Prime Day deals. Whether you're on the go without easy access to an outlet or you're dealing with inclement weather, having a power bank handy to top off your most essential devices is a wise investment. And you don't have to drop a lot of cash for a quality model. Amazon has slashed the price of the Anker Zolo power bank to just $18 when you use code ANKER1688 at checkout. And you don't have to be a Prime member to take advantage of the savings. 

This 10,000-mAh 30-watt portable charger with built-in USB-C cable is just the friend you need to keep you company. Since the cord is already there, you won't have to worry about forgetting it as you pack your backpack to get outdoors. Being USB-C enabled, it's great for juicing up smartphones, tablets, earbuds and other devices that might need a quick boost. You can even charge three gadgets at the same time thanks to the cord and built-in USB-A and USB-C ports.

Even if you aren't traveling off-grid, a portable power bank can really be helpful for day-to-day life. Sadly, not all places have accessible wall outlets for charging devices. You don't want to go to a coffee shop and find yourself limited on time because you don't have an alternative power source. A power bank can also come in handy if you live in an area with frequent power outages or if you just want to be prepared for an emergency.
