Charging Mavic 3 batteries

[Cammo]

New to this forum so hi! I'm wondering if anyone has had success charging multiple batteries using the charging hub from a USB C PD battery pack? I've just tried charging three batteries in the charging hub with a Cygnett Chargeup Edge Plus USB-C Laptop & Wireless Power Bank 27000 mAh however it only charged 1 1/2 batteries before the fully charged power bank died.

Considering the Mavic 3 batteries are 5000mAh I would have thought I should be able to charge at least 4-5 batteries.

Any thoughts or advice about charging from a battery pack like this?

Yes is a 5000mAh battery but is a 4S. Each cell is a 5000mah 4.2 per cell fully charge or 3.7V nominal. X 4.

Thanks for that info. Am I right in thinking that, in essence, the total capacity of one battery is close to 20000mAh (4 x 5000mAh cells) hence my 27000mAh battery pack only charging about 1 1/2 batteries?

That make sense

may be it's too late to reply but just in case.
mah really don't mean anything what count is how much watt hour. each mavic 3 battery holds 17.6 X 5000mah = 88wh max. I think your power bank is 27000 X 4.2 = 113.4wh max. most power bank has single cell so may be its able to charge one of mavic3 battery, if you counting on inefficacy of your cable and power bank circuit may not even able to charge one pack.
