If you own many DJI Mavic 2 series batteries either for the Mavic 2 Pro or Mavic 2 Zoom you may want to consider upgrading to a fast charger. These fast/rapid chargers are safe and can save you hours upon hours of charging time. If you purchase the Fly More Kit for the DJI Mavic 2 series it comes with a charging hub that allows you to connect 4 batteries at once. The charging hub however only charges one battery at a time, the only real benefit from the hub is it allows you to walk away and not have to worry about connecting each battery one at a time as needed.
With this rapid charger for the DJI Mavic 2, you can connect 3 batteries and all 3 will be charged at once simultaneously, again saving you hours of time. This can be especially important if you decide you want to go flying last minute and all your batteries are dead. You could be out the door in an hour instead of several hours. The unit also has 2 USB ports built-in that can be used to charge up your smartphone or tablet as well as the remote controller.
One question that does get brought up is “Will It Damage The Batteries?”. Now I am not a charging expert by any means I can only offer up advice from my experience. I have been using these types of rapid chargers for many years and I have never had any problems or a damaged battery. This charger has many safety features built in that prevent overcharging, spikes and many other protective measures.
