I have a 3 kw inverter but it does not do 3kw for 3 kw you would need 4.5 kw inverter.
so your 1.5 kw inverter should be fine for 700 watts +_
Cheers mate 
What panels did you go for Dave? and how close to the advertised 200w can you get out of them ?

Ive got 2x 200 watts and 100 watts
if your using a inverter does not matter
if using a jackory 500 watt it will only take a 100 watts in
eco flow 500 will take 200 watts in
I think you mean 1000 Wh, as it’s lithium battery is 46.4Ah.

Actually - should have been W … since it’s speced at 1002Wh … that extra 2Wh makes ALL the difference.

yes what solar will a 1000 AH TAKE PER HOUR

@RemoteIDsaveslives Did you get chance to try the UGREEN 65w charger on any drone batteries Wayne?
It’s done sound on the phone, not had chance to try it on anything else.

It’s charged the Mini 3 pro at 36w no problem
But on the Avata it started fast charging at 65w but after a while it seemed to drop to 40w and was slow charging, it was very hot as well
Not sure if it’s a low voltage input as the car battery I was running it off was getting low or it was just too much and overheating
I will test it again at home rather out in a field where I can stick the multimeter on it

Brilliant, cheers Wayne👍.
On the subject of Avata batteries, I ended up buying another Inverter but only 500w,an Energizer one, half the price.
I have a spare car battery, which my lad has kindly ‘donated’ seeing as he smashed his car the other week, charged it last night, ran my Avata batteries down this morn and put them on charge. They took the same time as normal, which is good👍.
The car battery is only a starter battery and is only 60 ah, and lead acid.
Going to run some more tests this week, seeing what and how long I can run things off of it, then buy a new one, probably the same but deep cycle.
The only thing is, I can’t tell what’s left in the car battery? Any suggestions?

inverter should tell you much in battery or buy cheap battery moniter
are you charging by solar power
Cheers mate, that’s literally what I did👍
Thought there might be fancy spark way of doing it😂.
If I’m out on the road, how can I tell, what fancy spark way of a testing what’s left? 
.
The simple and easy way is the voltage, don’t go below 12v
or
Car Battery = 60AH…or 720W
Avata Battery 2.4A x 14.76v = 36w
720/36 = 20 charges
But that takes the battery to zero, so the safe amount would be no more than 12 charges

Is something like the Jackery 1000 really expensive?
Some thoughts
- Jackery 1000 can be £750 on a good day.
110AH Leisure battery - £100, 2kw pure sine inverter (as there is in the Jackery 1000 - not needed for charging drones, obviously, but it’s there for other uses) - £200 … and a decent 12v to USB charger, another £50-ish - so already a good part of the way there… - 1000WH is what you get - every time, with these modern portable power stations. With a leisure battery, depending on what you’re running from it, and the voltage gradually fading, at some unpredictable point things may not work meaning that not all that 110AH power may actually be available to you. - you may only get 50AH out of it.
- USB, 12V and 250v pure sine - is EXACTLY what you actually get … from 100% charge to 1% charge. Clever tech in those Jackery! … and similar.
- 12V sockets are (on the Jackery) in fact higher than the nominal 12V stated - meaning that my MP car charger works a treat - as will others that normally need the engine running.
- Jackery 1000 - 10kg. 110AH leisure battery 24kg.
So - in essence - way more usable power, far less weight, one single, more portable, item.
Wins for me.

@OzoneVibe Wow! thanks Dave that’s a bit like using dynamite to open your front door when all you need is the key.
I never said it’s the only way to recharge a drone - my personal needs are more diverse and more demanding.
I was just giving what I believe is a real justification for the higher price for those that have a need.
One of these could have easily paid for half it’s cost, and avoided a load of other inconveniences, a few years ago, because the leisure battery route was a fail - mainly the dropping voltage and all the power not really being available.
