How does increasing voltage or current affect the power?
The power will remain the same for a particular load as we are not changing the load. so if we increase the voltage, the current will decrease to make the net power consumed by the load same as before. If we increase the current, the voltage will decrease for making the power same. The power will only change when we changes the load.

ELI5: what would happen if I plugged my power bank into itself?
The battery will discharge but shouldn''t be damaged. I''m assuming the unit is USB in and out. It has an internal charging circuit which will use some power while trying (and failing) to charge the battery. If it had no charger, you would just be connecting the battery to itself.
Step-down voltage regulator

Here''s the Truth Behind the Biggest (and Dumbest) Battery Myths
A device with only a little charge left will also sometimes shut off if it gets cold, as the decrease in power caused by the low temperature will trick the device into thinking the battery is empty.
MPPT Solar Charge Controllers Explained
The Rover spec sheet states the ''Max. Solar input power'' as above (not the nominal input power). Oversizing the Rover series will void the warranty. Below is a simple guide to selecting a solar array to match various size batteries using the Rover series MPPT charge controllers. 20A Solar Charge Controller - 50Ah to 150Ah battery
on battery power in response to distorted input message
The first one went down on what looked like a problem with the AVR (shutting off the power to the servers instantly, which, oh irony, is what an UPS is supposed to prevent). We got a replacement . But that and the first one had a series of events popping up regularly: on battery power in response to distorted input no longer on battery power
Understanding Low-Dropout Voltage Regulators (LDO) and its …
Since we need a simple and low cost solution we can rule out the switching regulator designs. A lithium battery can provide 4.2V during full charge condition and 3.2V on fully empty condition. Therefore, the LDO can be controlled to disconnect the load at low voltage situation by sensing the input voltage of the LDO by the microcontroller unit.

What happens to the output when voltage regulators …
The idea is, when the voltage becomes too low, the transistor will open and allow current to flow directly from the battery to the thing connected to the output of the regulator (possibly going through some resistors to get it down to 5 volts) and …
What Happens if You Plug a Power Bank Into Itself?
The input circuitry will convert the 10W into 9W at the battery voltage and will attempt to power the battery. What actually happens is, that the 9W of power goes to the output circuit along with 2W, which will be taken from the battery itself in order to supply the 11W needed by the output circuitry. In the end, energy will be lost to heat.

I am also getting a lot of alarms that say: "UPS: The battery power is too low to support the load; if power fails, the UPS will be shut down immediately." followed by "UPS: A low battery condition no longer exists", and if utility power fails Unit shutdown immediately. UPS configured Low Battery Duration is 2 Minutes.

When Cmos Battery Dies: Understanding The Consequences
However, when the CMOS battery is dead, performing a BIOS update can be challenging. Since the battery powers the CMOS chip, it is essential to have a functional battery to retain the BIOS update settings during the process. Without a working battery, the update may fail, leading to potential issues with the BIOS and system stability. 8.
What happens to excess power when batteries are full?
And many will set their battery bank voltage based on battery bus voltage (i.e., 9.5 volts to ~18 volts = 12 volt battery bank; 18 volts to 36 volts will be a 24 volt battery, etc.). What some folks have done is to connect their solar array directly to the input of a standard off grid AC inverter.
Lower power output when charging devices, is that ok?
@MaQleod, alright, lets see if i get this correct, so, if the device is charged with a lower amperage charger, it will charge slower, and if the charger is able to negotiate the power use, it is able to regulate the rate of the power the device is trying to pull, else, the device might try to pull power faster than the charger is able to supply ...

Question
Depends on the draw. Laptops (most) don''t work on line voltage, they work off battery voltage, the charger is just replenishing what''s used by the battery. If you have a gpu, that''ll be a big draw, battery goes dead quick, so the gpu is relegated to 3d apps, using the igpu as often as possible to keep the draw down.

What happens when a car battery gets too low | Batteries Plus
A car or truck battery has a limited number of times it can start your vehicle before it needs to be replaced. Most car batteries will last between 500 and 1,000 charging cycles, which works out to a lifespan of between three and five years, depending on driving habits and weather conditions.
What happens when a device draws more current than the power …
Practical power supplies have an internal resistor that is the sum of all the wiring and other components. In the model of such a power supply, the resistor is what causes voltage to drop as current increases. The power lost (converted to heat) through this internal resistance is why a power supply needs cooling. $endgroup$ –
Exceeding voltage or amps on SCC | DIY Solar Power Forum
Let''s say you have a 12V battery and it is at 13.6V. The 50A output would be reached at 680W input. If you were able to get 800W, the SCC would just "ignore" the extra power and you would just get the 50A output. No damage would be done. But as you''ve seen, exceeding the input voltage can be bad. Exceeding the output current is a non-issue.
