I'm using an auxiliary battery of 10000mAh.

How much does it cost to charge it once?

I'm charging it almost every day, but I'm wondering if I'll have to pay a lot of electricity.

I think it's about 10 won per charge

If you calculate it accurately,
The auxiliary battery is 4.2V when it's fully charged
So 4.2V * 10000mAh (=10Ah) = 42Wh
1 KWh is about 100 won, so it's about 4.2 won
Considering the power loss, I think it's about 5 won
