I just ordered some 18650 batt and out of curiosity, I want to know the correct capacity of it.
I have an usb meter, which read the following:
- Charge: 5.25V, 5683mAh
- Discharge: 5.09V, 2927mAh
The batt was labeled at 3300mAh. The powerbank contains 2 batts.
So I want to ask:
- The powerbank rated at 6600(3300x2)mAh @3.7V, mean rated 4884 mAh @5V. Is this correct?
- So if 1 is correct then actually the batt is only ~2000 mAh@3.7V?
- How to estimate the convertion rate of the powerbank?
Sorry if any noobie question, I'm totally new with this thing.
