The latest addition to my spark, RavPower 20100mAH charger with...tadadada - AC plug.Finally i can charge my spare batteries on the go, in the field, everywhere I go. It works great with the charging hub + it has usb and usb type C as additional ports.
The packagaging is quit lovely and the case it comes with is robust and a little smaller than the original spark case.
I am loving this especially on those days when you just dont want to quit flying.

Does it have the same charging time as when you charge it using a wall outlet?

So how many times can you charge a Spark battery (or how many Spark batteries) from this thing?

I charged the equivalent of 8 batteries through out the cause of a day and still had 2 bars left in the bank.
Spark batteries have 1480mAh, being generous let's say 2000mAH so technically 10 charges+.
I am loving this as I can charge multiple batteries on the go.
With a normal power bank I.e my Anker I can only charge the battery in the drone and can't fly for 50min. Now I can fly and charge at the same time.

I see already people explaning at airports, that this 600gramm Powerbank is really having only 20100 mA.
There must be a smaller way, methinks

You are violating physical laws. Or you did not really test this.
The power bank has 74 Wh and one battery is 17 Wh.
Assuming the batteries have 20% left, each needs 13 Wh.
Some power gets lost in conversion and disappears as heat.

I have the newer/bigger 99 Wh ravpower bank and get at most 5 spark battery charges.

He did not charge 8 batteries, he "charged the equivalent of 8 batteries"
Which sounds to me about 2 2/3 Spark 3S Spark batts could work for sure

Heli sorry, i wasn't specific enough, I owe 4 batteries  and charged them all up again - so the equivalent of having 8 flights instead of 4. You have the 27000 version? just noticed this one is the same price as mine so im upgrading.

So confirming that you were able to charge FOUR spark batteries using your ravpower 20100 with ac adapter. Did you use the charging hub?

A spare car battery with an inverter (12v dc to 240v ac)  should do the trick.
