Surprisingly light and portable
The Defender 20, which is about the size of your palm, is very portable. The frame as a whole is injection-molded to make it strong and light, and it comes with a DJI O3 air unit that isn't attached to anything. Not only does it follow the rules, but it's also the safest in its class, so you can fly whenever and wherever you want.

One-button Power Switch That Works
Better control with a single button that turns the device on and off and lets you set the colours and modes of the RGB lights that show how much power the battery has left. We added a safety circuit to the battery connector to make it last longer and stop sudden voltage or current spikes that could damage your electronics.

New Quick-Release Battery with a Type-C Charger
The Defender 20 comes with a 3S 900mAh battery that lets you fly for up to 7 minutes. The battery shell is protected from drops, and the new quick-release structure makes it easy to replace. The upgraded plug and play Type-C charger makes fast charging easy to use. In just 18 minutes, you can get 80% charge. The battery has an auto-discharge module built in, so when it's not being used, it will drain itself. This makes it safe and worry-free.

Very Easy for Users to Experience
Don't be afraid of the dust; just take off. Make sure the interface works right by using dustproof port plugs to keep it from touching anything outside. Make the interface last longer.

There are only six screws that hold the drone together, which makes it much easier to maintain and fix.

High-performance AIO that is fully plug and play, with 30% more redundancy to handle heavy operations. An integrated beeper makes it easy to find if it gets lost.

It's easy to get to all the ports and buttons.
