Do power outages ruin you cell phone battery or charger?

We Answered:

Does the phone still work now? If so, no worries.

Seth Said:

why a Laser diode gives more light with a bottom cell batteries than with a phone charger of more volts?

We Answered:

A phone charger isn't necessarily the same thing a power supply. It's a battery charger. They often times do more than just supply a voltage. Sometimes they adjust the current over time to match what the battery needs to charge making them very bad to use for anything else.

Also, unlike a light bulb which will get brighter as voltage increases, a diode drops a certain voltage. Putting more voltage across it won't affect that fact and can actually damage it.

If you want a brighter laser diode then the only real option you have is to get a higher mW laser.
