as stated above, i am wondering how to know how much charging energy a portable charger can hold
for example, we can have 1 product with 5000maH with 2 batteries but another product with 13000maH with 4 batteries.
does the amount of hours a portable charger can hold depend on maH or the amount of batteries?
2 batteries to 4 batteries meaning that product with 4 batteries has exactly double the storage inside or 2.6x (looking at maH)
hopefully my question makes sense, thank you all
@throwaway9435 mAh determines the amount of energy. the number of cells or batteries has nothing to do with it.
A 5000 mAh battery can output 5000 milliamps for one hour or 1000 mA for 5 hours or 500 mA for 10 hours, etc, etc
If your phone charges at 2.0 Amps (2000 mA) using the above 5000 mAh battery bank the bank would be depleted in approx 2.5 hours. If your phone has say a 2500 mA battery you should expect 2 charges from flat to full with the same 5000 mAh battery pack. Get a 10000 and double your capacity
Hope this helps. Cheers
Energy is Volts x Amps x hours. Volts x Amps = Watts. So energy is Wh.
Energy is not mAh.
However as the cells are similar voltages, using mAh is a rough approximation to energy.
If you can see a Wh figure then that is actual energy.
Yes, that is correct @nigelhealy watts are energy. Thanks for clarifying to keep the answer real.
I just wanted to keep it simple based on the question asked and I was assuming the voltage was constant and not doubling when going from 2 batteries to 4 batteries.
The possible length of the technical answer could not be given without adding a lot of confusion as watts are often omitted from smaller consumables.
