A 9 volt battery is stronger than a 1.5 volt battery because it has a higher voltage. The higher voltage allows the 9 volt battery to power more demanding devices and last longer than a 1.5 volt battery.
you better not. you need a 9V regulator for this, not a resistor!

No.
You can buy 9V batteries from almost any supermarket
Yes, a 9v battery can be dangerous if mishandled or ingested, as it can cause burns or internal injuries. Ingesting a 9v battery can also lead to serious health complications or even death. It is important to handle and store batteries properly to avoid accidents.
A car battery has six cells each producing two volts. A 9v alkaline battery has six cells each producing 1.5 volts. There are some obvious differences, like that a car battery can put out hundreds of amps and a 9v alkaline can only put out hundreds of milliamps, a 9v battery weighs 45 grams versus 45 pounds for a car battery, and so on.
You can use a step-down voltage regulator to reduce the 9V output from the battery to the 3.7V needed for your handphone. This will prevent the handphone battery from being damaged due to overvoltage. Make sure to use a regulator that can handle the current needed by your handphone.

yes the invert mini takes 1 9v battery. it is in the grip frame. you should get a 9v with the gun/
Current I = V/R V = 9V R = 100ohm I = 9V/100ohm = 90mA
