My mobile phone (an Alcatel) charger will supply 500 mA at 5 V. So the maximum continuous power it is capable of supplying will be the product of these two -i.e. 2.5 W. Of course, it won't necessarily ever reach that value in practise.
This is not advised! The 9-volt charger might have a current limiter so that nothing burns up, but it any case if left on it will destroy the 6 volt battery by overcharging. A 6-volt charger is not expensive.
You need a 6 volt charger. When you buy a charger look for one that monitors the voltage level of the battery while it is charging and when the battery is fully charged it will turn off. Indiscriminate charging of a small battery can easily destroy it. Being left on the charger too long can boil the electrolyte out of the battery. A battery can not recover from this action and it will need to be replaced.
You need a regulator.
Just under 2 volts
18.5v should be fine for a 15-16v application. remember circuits will only draw the amount of current they need, no more. you could also try adding a current limiting resistor in series with the load. use a VOM for this testing (as the load).
yes cause you can play ds and dsi while charging
You will need an adaptor
12 volts.
5.1v is the Voltage, You need to also look at what the Amperage rating is on the charger. 500ma, 1000ma, etc. How many Milliamps?
A charger designed to run on 220 volts only will not operate on 110 volt supplies but single voltage chargers are rare. The majority of chargers will accept any AC voltage from around 100 volts up to 250 volts. To find out, take a look at the information panel on the charger. On the panel there will be a voltage rating as well as other data. The voltage is likely to say something like "Input - 100-250 VAC". As long as the voltage available is within the upper and lower limits, the charger should work. You will probably need an adaptor to plug it into the local mains outlets but once you have that, you should be set.
No, you can not charge a mobile battery using torch cell. <<>>> i think charger need and mobile the same. also battery.
Without knowing the maximum output current it was designed to produce it isn't possible to say exactly how much voltage a charger produces. Also, was it intended to give a slow or a fast charge? In general all that can be said is that the output voltage of a battery charger must always be slightly higher than the nominal voltage of the battery it was designed to charge. This is for the simple reason that it won't be able to put any charge into the battery unless the charger's "on-load" voltage is higher than the battery's voltage. For the same reason, a charger which can deliver a high output current (amps) will need a higher "on-load" output voltage than a charger which can only deliver a low current. Also, when it is switched on but is not connected to a battery, the output voltage of any charger will always be higher than when it is doing its job of charging a battery. That voltage is called the "no-load" voltage. Assuming the battery being charged is a standard low-voltage type, of less than, say, 24 volts DC, it is quite safe, using a standard electrician's voltmeter, to measure the load and no-load voltages of the charger as described above.
To charge your iPhone in Europe, you will need a plug adapter to fit the European outlets and a voltage converter if your charger is not compatible with the higher voltage in Europe. Simply plug your charger into the adapter and then into the outlet to charge your iPhone.

The charger can test the % left in the battery and the voltage remaining. It can also test a car's alternator.
No, you should not charge a 6-volt 4.5Ah sealed lead acid battery with a 12-volt charger, as the voltage is too high and could damage the battery. Sealed lead acid batteries need to be charged at their specified voltage, typically around 7.2 to 7.4 volts for a 6-volt battery. Using a charger with the correct voltage and current rating is essential for safe and effective charging. Always select a charger designed for the specific voltage and chemistry of your battery.
A true voltage transformer is not designed for power applications; it will only supply so many VA to your charger. I would suggest you purchase a power transformer for this application. You'll need to rectify the AC voltage, and minimize the ripple. Rectifiers are used for the first part, capacitors, varistors, and power transistors can be used to minimize the ripple.
