ZeroLemon 26800mAh Battery Pack | $30 | Amazon | Promo code B8K8D662

$30 is a great price for a battery pack with Quick Charge 3.0, USB-C, and 26,800mAh of capacity, but it’s kind of astounding for this model, which also includes an LED flashlight array on one side, and a freakin’ solar panel on the other.

Obviously, that little panel won’t recharge the battery very quickly, but it’s fine if you just need a little emergency power to make a quick phone call.
