Charging batteries off the spark??

[v2kdj]

Does anyone know how to connect a battery to a usb port from a powerbank while it is off the spark?
I was wondering if this could be done so I don't have to use the spark as a dock to charge and swap the batteries. Just to confirm, this is not using the 3 battery charging bank from the flymore combo.
I want to be able to charge a spare battery while flying with another.
Thanks

I use the 3 battery charger connected to a power pack with an AC connection.

What you ask exist by DJI: Buy Spark Portable Power Pack - DJI Store
Can charge 2 batteries when you fly the Spark but charging will be always longer than fly time of Spark.
It's expensive but work nice.

Thanks for the response. Think I found what I'm after in another link...Should have searched better...

I have a portable charging station but find it a little bulky in weight and size. I was looking for a battery dock that will run off a QC3 10000mah portable pack.
I've ordered it now and will let you know how it is when I've tested it.
Cheers and happy flying.

But you need a car and swap batteries as they are charged
I agree, it is much much cheaper.

Based on other previous experiences, I am very hesitant to use 3rd party chargers for my Spark batteries. On a Phantom 1, I have seen shortened battery life, burnt wires, and destroyed batteries. Just me....but I'm sticking with DJI.
