And again , Poor manuals for power series . There is no information about charging . And charging power .Now charging from wall socket AC . If you have power switch to 600W - you will get MINIMUM charge power 1000W in combination power station + ext battery
but if you have that switch to 1200W - you will get 1700W in the same station+battery set . For those who will charge it in fields or with poor wire harnes or sockets be careful , and keep this information in your mind . This information isnt described in manuals .
I havent test it with car fast charger yet . And have only one ext battery .
Can DJI add explanation about will be charging power depends on quantity of ext batteries ?
Add please this important information to the manual

Hi there. When paired with a Power 1000, the expansion battery's recharging power can reach 1950 W, reaching 1024 Wh in approximately 36 minutes for fast power when you need it urgently.
Note: 1024 Wh is measured at an ambient temperature of 25° C with one expansion battery connected to DJI Power 1000 (via SDC to SDC) and being recharged by grid power at 1950 W via the AC port on the power station. This data is for reference only. Actual user experience may vary.

If you have any other questions, please feel free to contact us.

Yes. This topip was to help other users , because no information about that in the user manual . Maybe in service manual it does , but in user manual that is available - nothing have been found . Max power i have reached was 1800W , but it was just for test , regulal charging power was +- 1000 w until the end .  As you noted i have also get such values for only one expansion battery , but can you tell if it depends on quantity on expansion batts or it will stay 1950/1024 for no matter  how many baats are connected ?

Hi there.
1. The maximum charging power of the regular version of DJI Expansion battery 2000 is 1950 watts, and the maximum power of the North American version is 1500 watts. This is stated in the DJI Store.

2. In 220V areas, 10 amp sockets are usually used, so the maximum output power that the socket can support is 220*10=2200 watts. In 110V areas, 15 amp sockets are usually used, and the maximum output power that the socket can support is 110*15=1650 watts. Both are higher than the maximum charging power of Power 1000.
When designing our products, we took into account the maximum power that sockets in different countries can provide, which is lower than the maximum power standard to avoid the situation where the power is too high and the socket is burned out.
We recommend that you ensure that the wire diameter of the connected socket meets the requirements and can provide sufficient power before use.

3. When connecting a power pack, the maximum charging power is 1950 watts/1500 watts, regardless of the number of power packs.

4. Can you provide pictures to prove your statement “but if you have that switch to 1200W - you will get 1700W in the same station+battery set”? The Power 1000 will not get more than 1500W of charging power.

Hi. Thanks for your detailed explanation.
Sure, here is a screenshot when switch was in 1200 w position

Hi, there
Sorry for replying late, after checking, in Poland, the maximum charging power of the plus pack is 1950 watts, and the power input of the Power 1000 is going to be more than 1500 watts.
In 220V areas, where a 10 amp socket is usually used, which can support a maximum output of 2200 watts, the Power 1000's maximum input of 1950 watts is lower than the maximum output of the socket, and the Power 1000's power input is lower than the maximum output of the socket.
Thanks for your understanding and support.
