Lithium batteries are not 5V batteries but nominally 3.6V, 4.2V when full and empty somewhere below 3V as defined by battery manufacturer and different value may be used by this device. And their internal organization in series/parallel/both is unknown - the capacity might just be a sum of all batteries together, or then they really are all in parallel. If you want to model a lithium battery, model the battery, not the device that has batteries. | |

| Nov 15 at 0:07 | comment | added | pnatk | Are you sure? But it says 4-cell battery 5000mAh in specs. Do you mean they are in parallel? | |
| Nov 14 at 23:22 | comment | added | Justme | The power bank isn't made of four 5V batteries in series. The 20V output does not come from a 20V battery. There is a voltage converter that boosts or bucks the internal battery to 20V while the actual batteries discharge, so the voltage stays at 20V until batteries are empty and it shuts down. So you could simply look at discharge curve of a 5Ah lithium cell with constant 5W discharge. | |
