Straight out of the box the Phantom 4 is ready to fly, as long as you learn the basics of how to fly it and how to stay safe when flying it, however, here are the full list of things I’ve purchased for the Phantom 4 and what I believe are ‘must have’ accessories:
A decent larger memory card
The Phantom 4 comes with a 16GB card but that’s quite small in reality, so an upgrade was needed you need a memory card that can handle the 4K footage produced by the Phantom 4. A SanDisk Extreme is the bare minimum with a SanDisk Extreme Pro being my go to card for anything I need to ensure 100% works.
A short cable
Having a large cable hanging around doesn’t look good and it also often tangles around things
A secondary battery
Overpriced IMO but the only option and a must for any long days out / professional filming
Originally I was planning on buying this one from Amazon, however after further research, it has become obvious that using one of these would cause damage to the Phantom Charger. Instead, I’ve got for the official car charger.
Why would it damage the charger? The DJI mains charger is a switch mode unit which is designed to operate on a pure sine-wave mains supply and the cheap inverters suggested above put out a square wave 240v out put that will probably damage the DJI charger. Thanks to Nick for this explanation.
An external battery for your phone / tablet
Having a low battery for your display will stop you flying in many cases. I always pack one of these Anker battery packs just in case.
A set of replacement propellers
You get two sets in the box but having another set is worthwhile especially if you’re a newbie.
The official ones are the only ones currently available and work very well.
A backpack & hardcase
From my old Phantom 2 I’ve got a B&W hard flight case that just fits the Phantom 4 and remote, however, it’s bulky and a pain to carry but ideal for storage / long trips etc.
Having a backpack is essential, amazingly I have an Eastpak bag that fits the controller, Phantom 4 (without blades attached), spare battery and the other accessories in perfectly (albeit a little snug), which is ideal for day trips etc but I wouldn’t want to rely on it. Manfrotto sell a decent backpack for the Phantom 4 which I’ve not tried yet but I think I will grab.
A portable SSD drive for storage of all those 4K files
If it’s a very sunny day you may find an ND filter will be extremely useful at reducing the amount of light that enters the camera (as the Phantom 4 has a fixed aperture). ND filters will also increase motion blur, remove Jello effect from bright sunlight conditions and reduce reflections if you grab a polarizing filter.
ND 4 = Daylight use
ND 8 = Bright daylight use
ND 16 = Bright daylight use heading into sunlight
Anker Micro USB 3 Card Reader
Pretty obvious what this does and it’s my go-to brand for tech.
