AUKEY is one of the more popular names when it comes to portable chargers and battery packs these days, and they have plenty of great options available, including this 20,000mAh battery pack. This is a fairly large battery pack, that includes both lightning and micro USB input, so you can charge it with either cable. We also have two full-sized USB ports and a flash light included, which comes in handy for those times that you need some light, or you may be stranded in the middle of nowhere. With a capacity of 20,000mAh, you'll be able to charge your smartphone on average about 6-7 times before needing to recharge the battery pack, which is pretty impressive, to say the least.
This battery pack would typically sell for $37.99, however right now Amazon has it for just $29.99. But if that wasn't enough to tempt you into picking one up, AUKEY has a promotion going on that marks it all the way down to $21.89. And at that price, it's tough to pass it up. You'll need to use the promo code AUK2MAHL at checkout to get the additional savings. It is eligible for Amazon Prime, so you can have it on your doorstep in less than two days.
