While Amazon Prime Day may be officially over and in the books, some deals have been extended to give shoppers a chance to save if they missed out the past two days. If a portable charger is something you were hoping to grab during the sale, one of the best Prime Day power bank deals is still up for grabs, and it's more than worth a look. Anker's 347 40,000mAh 30W power bank is one of the largest power banks you'll find on sale still, making it perfect if you've got multiple devices in need of a quick charge on the go. It's also one of the best values you'll find, since you can still get it for a solid 20% off right now.
