It doesn’t have to be a crisis to leave home while your phone’s battery is almost dead. With the 16750mAh Portable Power Bank from RAVPower, you can charge it back on the go and recharge other devices with plenty of juice leftover. Although it is normally sold for $36, when you clip the coupon on its product page and enter promo code 50W5C77D during checkout, Amazon offers nearly 60% off its regular price.

This power bank was designed to be much smaller and lighter than previous portable RAVPower chargers, and with its 16750mAh battery capacity, it can recharge the iPhone 8 more than five times before it needs to be recharged. Its 2A input provides a fast way to refuel while its two USB ports provide a total of 4.5A of power. There is also a LED light for the battery indicator so you never have to wonder about its charge, while advanced safety features protect against overload and short-circuit.

You will need a way to power this portable charger, and while at home a USB wall charger is fine, adding a car charger to your order will allow you to power it while you’re on the road as well.
