Presumably the Jackery and Goal Zero type solutions, will not charge the drone batteries simultaneously. (When I do the calcuations, this has a big impact on how many missions I can run back to back)

Using an inverter is wasting energy. There is no reason to go from 12vdc to 110vac and back to your drone battery voltage. Using a DC charger is much more efficient.When you are passing the $350 in a solution for the field let me thinking is much better get an inverter.
An inexpensive one:
Another excellent option with good quality and quiet. Honda EU1000i 1000W
HONDA EU1000i -- 1000 watt 120V inverter generator with CO-MINDER | eBay
AC Output 120V 1000W max. (8.3A) 900W rated (7.5A). Engine Honda GXH50. Noise Level 50 dB(A) @ rated load 42 dB(A) @ 1/4 load. 6.8 hr @ 1/4 load. Fuel Tank Capacity 0.55 gal. Starting System Recoil.www.ebay.com
Those are inverter generators, not 12 V power inverters. There is no 12 V supply involved - they generate 110 VAC and then you use a regular 110 V DJI or third-party charger.Using an inverter is wasting energy.

I see that now. I read inverter in the text and didn't click the link.Those are inverter generators, not 12 V power inverters. There is no 12 V supply involved - they generate 110 VAC and then you use a regular 110 V DJI or third-party charger.
Same here. My Honda 2200 powers the chargers and any external lighting I may requireI have a Honda EU2200i and a Yamaha EF2000iS, either of which will comfortably feed my CDC PRCS 4-battery parallel charger, which pulls around 700 W with 4 batteries fast charging simultaneously. Obviously you could also power a regular DJI charger with either of those generators.
Those generators each weigh just under 50 lbs, so not really suitable for hiking though.
I've used my Honda EU2000i for a/c power out in the field on occasions when the site I'm shooting is either abandoned or totally off-grid. This is for charging purposes - batteries / laptop / tablet flight screens. I can also make sure I'm properly topped up with fresh espresso as well. As already mentioned, make sure it is an INVERTER genny that outputs pure sine wave... stepped will damage delicate electronics. Better to plug a 5/6 way quality surge protector extension lead direct to the a/c output and then plug all the kit you want to use into the extension lead. Belt & braces with a/c.I raise this as a new thread, because the similar threads are about suggestions of possible solutions, but Amazon feedback frequently shows that the possibly suitable generators, turn out to be unsuitable for one technical reason or another. Hence the question, does any one ACTUALLY use portable generator to successfully charge their Mavic 2 batteries in the field? and if so - which generator do you use please? Thanks
