Been examining various power pak options to charge tablets, batteries, Radio controllers, or even Notebooks (MacBooks or Surface PC) when away from a electrical power source. My vehicles have a 110v Source available, but I'm generally not wanting to use this unless engine is running or driving on road. I'm a little cautious of battery getting pulled down lower than desired if engine off.
I've tried several brands of the 10,000 to 20,000 mAh with 2-4 Ports from Best Buy. These are basically useless, even to charge the RC or Tablet. Some won't even work on newer phones... and if they do, it's at a slow charge rate, not a rapid charge. If these 20,000 units have 3-4 ports, their max port charge rate drops from 2.4 to 2.1 which may effect the device from not recognizing a charge. Some that say they include a 3.0 amp port, I didn't find to work with Samsung Tab S4 or iPad Pro tablets. I've noticed on RC (DJI, Parrot, PowerVision) units, the lower charge rate won't even activate the charge circuit so the RC doesn't accept any charge.
The lowest that provides usable charge to several devices are the 30,000 mAh units.
This unit can handle several devices, it's water & dirt proof, tough little pak with enough juice to keep RC's & Tablets charged.
Techsmarter Rugged @ $85
Haven't tried, but I doubt it'll do much for lipo flight batteries... even the smaller MavicAir or Anafi, not enough storage for the demand.
Plus the connections would be a challenge with proprietary charger connections that provide 110v AC or 12DC Aux on the source end.
My Solution:
For a carry pak, the above 30,000 mAh unit would work, but not enough if you're wanting to charge Notebook and multiple Flight Batteries.... even a small Frig to toss tablets in on hot days.
The research route went to larger "carry" paks that provide much higher watt, voltage & storage and clean Sine Wave current.
I found a very nice compact unit, actually pretty light at 6.5 lbs, 90,000,000 mAh / 298Wh, 110V 60hz 300W Pure Sine Wave that includes 2 110V outlets, multiple charge outlets from USB 5V 3.1A, USB-C 5v 3A, 12V 8A, 24V 3A. All with intelligent circuits and surge & short circuit protection.
PryMAX @ $280
What have other's found or applying for Power Source?
Others just using an Invertor plugged to your battery?
If using an Invertor, don't use the Cig Light 12V Aux port.... risky over time.
Couple of nice Inverters:
Lighter side @ $40
Ample 2000W Unit @ $130
