How can I charge my phone without electricity?
If you lose power, turn a laptop on (but don’t unlock the screen) and use your iPhone or Android cable to charge your phone via the USB ports. Most newer laptops can charge a smartphone multiple times.
Can two 9V batteries start a car?
In theory, you could string together a whole bunch of small 9V batteries in series and in parallel to get a high-capacity 9V or 18V battery and then step up or down the voltage to about 12V-14V. Your car may tolerate 18V but I wouldn’t risk it. You’ll need a lot of these batteries though.
Can a phone charger be used as a power supply?
“Pass me my Phone Charger”…… Your USB Smart Phone Charger is actually a Power Supply! As it designed to give a constant output, your Phone actually does all the charge control. This is designed to offer flexibility so your phone can be plugged into any USB port, on your PC for example.

USB chargers are ubiquitous as basic 5V switching supplies. It will work, given you buy a decent/reputable usb charger and not a cheap knockoff of questionable quality.
What is inside 9V battery?
Most nine-volt alkaline batteries are constructed of six individual 1.5 V LR61 cells enclosed in a wrapper. These cells are slightly smaller than LR8D425 AAAA cells and can be used in their place for some devices, even though they are 3.5 mm shorter. Primary lithium types are made with three cells in series.
How long will a 9V battery last?
Typical 9 volt battery has 500 mA hour capacity, continuous use would provide 25 hours per battery. All batteries are different, so 25 hours is an average, if it is turned off some times the life will be much longer.
Is 9 volt a boy?

Can we charge 9V HW battery?
Q:How is it recharge? A:Not rechargeable. Use and throw like other ordinary batteries.
Can you charge a 9V battery with a 6V charger?
Yes, you can, but you need to drop the voltage so that the 6V battery does not over charge. Either a resistor or an Inductor with enough resistaance will do the trick. But you need to know the size of the battery, and the current that the charger pushes out.
What happens if you put a 9V battery in salt water?
Salt water is much more conducive than regular water, so the battery would discharge more quickly and the current will break down the salt by electrolysis, producing hydrogen and chlorine gas.
