Like many of you, I have struggled with charging Inspire 2 batteries in the field. With TWO batteries required for ONE flight, and the slow charge times from the OEM wall adapter + DJI charge hub it seemed the only option was to buy more batteries at $160 USD each ($320 USD per flight pack).
Of course buying more batteries means also buying more wall adapters, and buying more wall adapters meant buying more DJI charge hubs. After all that you are left trying to carry the tremendous weight of these batteries with you on jobs and in the field, and ultimately there still is no way to charge in remote locations unless you also bring along a large, heavy, gasoline generator. All that and it still takes 90+ minutes to charge a single flight pack.
I have come up with the ultimate solution that has zero compromises and offers the best results across the board. The device I built can:
Some other stats on this device...
I started designing this device in the spring of 2017 and finally have it completed now that it's the end of summer. It took tremendous efforts to bring this project to fruition from many different people and companies.
I made this project for my own useage, and it is a highly professional product for a highly professional use-case. I made one extra set of frames so I could make a second device to sell if an appropriate offer ever came along. For now, I'm really happy that the 10 batteries I have (5 flight packs) can keep me in the air without interruptions for an unlimited amount of time if a car, generator, or wall outlet is available!
Feedback is welcome!

I have come up with the ultimate solution that has zero compromises and offers the best results across the board. The device I built can:
- Utilize power from a 90-264v AC wall outlet
- Utilize power from a 10-25v DC car/truck/boat battery
- Charge up to SIX (6) Inspire 2 TB50 batteries at one time
- Charge ALL 6 of those TB50 batteries in approximately 42 MINUTES
- Transport up to 12 TB50 batteries at once
Some other stats on this device...
- The AC power adapter is 1500 watts
- It can draw up to 100 amps from a 12v source (so make sure the engine is running and the alternator can keep up!)
- It has 6 discrete power outputs in the form of XT60 connectors that can plug into TB47/TB48/TB50 batteries, OEM DJI charge hubs, Inspire Transmitters, etc.
- It has two high output 2.1 amp USB ports for charging mobile devices
- Each discrete output channel can regulate the amperage from 1 amp to 10+ amps (the maximum current TB50 batteries will accept before refusing to charge due to "over current" is 10 amps)
- The system has failsafes for excess current draw, over/under input voltage, reverse polarity, and fuses for each discrete output channel.
- The entire system hardly creates any noticeable heat even under heavy usage due to the air cooling systems, overly heavy gauge wiring, and efficient power conversion
- The case is a Pelican 1510, which is allowed as a carry-on for airlines. Fully loaded with the 10 TB50 batteries I own it comes in at 42.5 lbs, which is under the 50 lb weight limit for airline baggage.
- When operating on AC power the unit has a 24v auxiliary output for external accessories that can utilize 24 volts
- Adapter cables can be made to charge Mavic, Phantom, and other battery types in the future
