There are tons of portable batteries on the market, but few can claim the amount of features that ZeroLemon's 26,800mAh solar charging pack can. If you've been looking for a battery and you're a more adventurous individual, you might want to jump on this $39.99 deal, which is achieved with a coupon code you'll find below.
This rain- and shock-resistant battery measures in at a whopping 26,800mAh in capacity. It has one USB Type-C port that can input 5V/2.8A and output 5V/2.4A (Power Delivery doesn't seem to be supported), one USB-A port that supports Quick Charge 3.0, and another 5V/1.5A USB-A port. There's also a 5V/2A microUSB input. The highlight feature here is obviously the solar charging; while the battery won't charge at all quickly via the sun, it'll come in handy in an extreme emergency. There's also a large flashlight panel with four modes, including an SOS pattern.
