When it comes to USB Battery Packs, RAVPower makes some of the best ones on the market. They currently have the USB Battery Pack I carry as a daily driver on sale for the low price of $55.99 with free Amazon Prime Shipping.
The RAVPower 20,100 mAh USB Battery Pack offers a wide selection of unique features that set it apart from other USB battery packs on the market such as support for Qualcomm’s new QuickCharge 3.0 standard which allows you to re-charge compatible phones in minutes rather than hours. This battery pack is also backwards compatible with QuickCharge 1.0 and QuickCharge 2.0 which is more common.
The most stand out feature of this USB Battery Pack however is the addition of a USB Type C Port that can be used as both a charging input and output device. This means you can use this battery pack to quickly charge your Nexus 6P, 5X, 2015 Mac Book, 2015 ChromeBook Pixel, Pixel C or any other device with a Type C port. It provides enough power to show “Charging Rapidly” on both my Pixel C and Nexus 6P.
After you are done discharging this battery pack, you can either plug it in with a typical Micro USB charger or you can opt to use a USB Type C Charger to re-charge this battery pack even faster. The final stand out feature with this battery pack is that it is one of the few USB Battery Packs that can be charged rapidly via a QuickCharge 3.0 compatible charger which means that you can re-charge this battery pack in as little as 4.5 hours.
