Hi. I have try the 1kW charger . Follow all instructions in manual. Just wanted to try to recharge Power 1000 and got only 560w max charge power . All sliders in DJI Home App was moved to max 1000 w . Power 1000 was started charging from 31% .
Does anybody have already try this charger ?

Small update. I think i know why it can charged on 560 max . The only thing i missed - was that i forgot that charge switch on the station was on 600W maybe that was the reason . will check it soon . But there wasnt anything in the manual about that switch... . So i have charge the station using that charger from 31% to 96  % . I have drive +-40 km for that . The maximum output i saw during the ride was 588 w closer to 89-90 % of charge. After 94% the cherge power was dropped to 200+- watts. Generally not bad, Wires + connectors + charger + station wasnt too hot . I think max temp on a charger housing was +37C . But its with power 560W . i will reply after i test with switching the station charging switch to 1.2kW

Nope. Yestarday i have switch the station to 1200W and try again , the charge power i got was 560 watts . So i can not get 1000 watt in anyway . Is it a trick or what shouldthink about 1kW charge power ?
Sure 560 watts is anough to charge the station , Yesterday i have chrged from 80% to 100% in 20 minuter of ride. Its not bad , but it is 1kW SUPER FAST CHARGER ......i want just see this 1000w .
By the way output voltage is stable 14 volts , firmware is latest   .901 . Connected directly to the battery .

I do not know what happened , but when i connect my Power 1000 to the charger today , it starts charge with 1058 w.

OK, so a couple of things

Providing the settings are correct, You have a few reasons why this happing.

1. Temperaturere of either cells or charger.
2. (most likely) avalible power from alternator - if your car battery needs a good charge and/or your running other stuff of you car battery, - Lots of other reasons why your alternator cant supply the current needed.. .. If it happens some of the time,  I would not worry but if its happening all the time, you might need to look at a new alternator or repair you current one.

1000w is alot (its so good but) and some car alternators might just not be able to keep up.

also the 1200w switch is ONLY for the AC charger.. has no effect on the alternator charger

Hi there. Thanks for your reply .But its not my case .
1- accourding cells temp you are generally right , but in my case was all at the same temperature. Just took P1000 to the car from home, connect SDC and start my ride. It want too high temp as an too low . just same conditions .
2- i have 2 parallel battery system in my car with alternator 150A )) . I have concrete 14.1-14.2 v with 560w , and the same voltage got yesterday with 1058W load . It have enough power for charging .

I thing my problem is that after first day of usage i dismount the carger for night , but on the second night i have left it it the car and it somehow reset itself . I will try it tomorrow i guess in a long trip .
So i think if i left it in the car for the first night - i hope i the result was the same . But i think restarting the unit with the swich after changing the charge power in APP can have same effect ,

Yeah , already got it )) . At the beginning  whe i got such situation it was the only weird thing in my mind .
But you can not deny that the user manuals for power line of DJI products looks very poor )) as for power1000 itself and charger, external battery pack 2000 ... It could be better))

having dual battery just makes what I said more of possibility.

also voltage dose not translate to available current, in particual with modern smart alternators..

Its very possible your alternator is seeing its primary battery is full and you alternator is ramping down to save fuel ..

ANYHOW... the best possible solution  here is to give DJI feed back, WE NEED MORE INFOMATION FROM THE APP..

the app needs to have a diagnostics section, that can tell us what the charger is doing...

I can assure you somethig in the charging computer is telling it that i can only draw that much.

1000w is alot of current at 12VDC - can start a fire in seconds if not ms... ifomation is super important.

Yes , at the same time the load(this time its charger and power 1000 ) is conected without a feedback to the car 12v circuit , so the only way to control is to monitor the droping voltage on the car battery . DJI charger doesnt know what current actually can be provided from alternator , Im sure it will fry full set current until see the droping input voltage.
But according the APP i fullly agree with you , its very pure params you can control , and im very glat to see that you are really understand how dangerous the charger and power station can be and how importand to control as much parameters as we can . I have described it in my thread about DJI Home app wishes . It will be great to see it looks like DJI fly APP .

Ha)). We both were wrong in our conclusions about 1200/600 charging switch. It was the reason the charge current were limit in 560 watt

I have checked it one more time on my way back home,  and got the same results . If station is charging and swich is set to 1200 - you have max charge power 1000+ w , and current wires i mesured was 70-75A . If i hot switch it to 600w then i got 560W of charge power with current 35-40 A . Why i have had a problems on the second day when i switched (i guess switched)))
1. Why it wasnt shown in manual and customers need discover it by themselfs ?
2 . Its very inconvinient to control it manual . you need each time check if switch is exactly in that position you want . sometimes it can be (like today i have) need to stop and set switch when you forget it do previously. It will be easier to make such switching in APP.
3. And again , make please mo parameters to control in the app . for Charger ,im sure you are controling not only voltage )) , we need be able to control temperatures , currents , And for Power1000 itself, like i mentioned earlier in my topic for DJI Home wishes .

So we can conlude that the switch 1200-600 is valued for final DC-DC converter , bat not for ACin-DCin, i do not know what for i can use this knowledge )) but now we now that ))
By the way i have control temperature while charging on 1060W - it was normal . On wires in, charger, and power station. Alternator was out of my termal camera view due its location , but i think it was be little bit hotter then usual . Charging time mostli the same as using AC socket.

Hi . I have test this charger during all holidays  and can conclude that it works very nice . I can give maybe 7 or 8 of 10 . My average ride was +- 100 km , ans its very good that i can charge the station from 10 to100% during that time. I have try different  power modes and can tell that at 1000W some times it limits the charge power to 600-800 watts , i think it depends on charger temperature , but due to we can not see it in the APP (Why still not ?)  i can only check it with thermal camera , and found that it was max 40 +- 3 C inside the charger. it was the hotest part , battery was 26-28 C  inside . and after some time it returns to 1060W charging . So i m using it most of the time at 800W manually set , and have it stable until 96% of charging when it limits the current i think for balancing of the cells  . IMHO 800w enough to most of the conditions it can be used for .
As for installation process
made it through SB50 connector , to be able fast dismount if i need use it in other places then my car . I have checked it with thermal camera within the the charging in max power output 1060w and it have the same temp as wires .
Continue testing , i hope to get finally my 2 kw battery extantion for the Power1000 and test both charger and set of Power1000+2000.
Hope see some changes in APP .

one importatn advise for this charger. Tha charging process should be finished in one ride session . If you stop you ride for a long time and then resume - youll get some weird charging process . It stuck on 99% for long time , in my case it was somthing like 35-40 minutes and with charging power 560-600W . because usually at this percenage of charge i have 150-200 shortly . for couple minutes and then 100W, 50 and full . When you this never heppens when it charges in one ride cycle.
