RAVPower is another relatively big name when it comes to portable batteries. This 22,000mAh portable power bank from RAVPower is currently on sale for just $39.99. This is a three-port battery pack, which will allow you to charge three devices at a time. Meaning you can charge your smartphone, smartwatch and tablet all together. There's no Quick Charge 3.0 included here, but there is iSmart technology. This is proprietary technology from RAVPower that basically talks with the device that is charging to see how much current it can take without damaging it. It will do a max of 2.4A per port, which is pretty close to the speeds of Quick Charge 2.0.
