It makes it easy to get back in the air quick. This is a very nice charging hub. It charges the batteries very quickly was well worth the money going with a dji product. You could get a cheaper charger, but you get what you pay for. 记住这一点. This hub can charge up to three batteries at once, as well as having two standard. Usb ports and a micro usb port, so you can also charge the rc as well as the batteries. I highly recommend this hub for all who own a spark Music being able to charge three batteries. The spark remote and my cell phone all at once makes this product awesome.
