Volts * Amps = Watts
12 Volt * 2 amp = 24 Watts
Not sure about how many Watts your 36 volt charger uses, but you can find out by this formula... Volts X Amps = Watts.
Remember that watts are voltage x current(amps) The number of watts you can get from a 48V battery will depend on how many amps the battery can deliver and how much the load can draw.
To charge a battery amperage is needed. This is done with a battery charger that supplies an amperage to the battery when the battery is connected to it. The rate of charge is dependant upon the discharge condition of the battery. The time to charge the battery is dependant upon the rating output of the battery charger.
they use about 5 to 10 watts.
The iPad charger provides 5.1 volts at up to 2.1 amps, so the total power rating of the charger is 10.71 watts.
The Makita Battery Charger is used for Makita batteries. This battery charger is capable of charging many batteries depending on the voltages for the batteries.
No. The speed at which the charger will charge the battery is determined by how many amps the charger outputs.
No, an automobile battery charger outputs 12 Volts. This is far too many volts to charge a 5 Volt battery. You would destroy the 5 Volt battery with this charger.
It depends on what kind of charger your talking about. Im assuming some type of smart phone charger... typically about 5.1 volts at .8 to 1 amp.... current ( amps) times voltage equals power (watts) so.. around 4 to 5 watts
83.3333 Amps <<>> The answer to this question, how many watts are drawn from the battery, is dependant upon what the amperage of the connected load is. A 1000W rated inverter is the maximum amount of connected wattage load that can be used from the inverter. W = A x V.
You cannot compare these two totally different things. As far as amperage the charger puts out more amps if it is an auto battery charger and also puts out 12 volts. If you are talking about a 9 volt battery charger then the battery may or may not be more powerful, it depends on how many mii-amps the charger is putting out.
That would depend how many amps you want to charge it at. Ohm's law says: Amps=Power divided by Voltage So, if you used 12 watts, you would be charging the battery at a 1 amp rate (very slowly.) If you used 120 watts, you'd be charging at a 10 amp rate. (Such as a car battery charger). but u have to be careful and not charge them too fast and overheat them.
There is no one universal laptop battery charger. One can purchase a battery charger appropriate to one's needs at from many companies, including but not limited to Pronto Charger, Best Buy, Batteries Plus and Ever Buying.
A battery float charger is intended only to keep a fully charged battery from losing its charge. It will NOT work to charge a battery that is discharged or damaged. Check the voltage of the battery to be charged. Do not use charger if the battery voltage is less than 9.6 volts.
There are many places to buy a battery charger for a phone. Some places include Best Buy, Wal-Mart, Sears, phone retailers such as Verizon, and many others.
about 15 per hour its not a lot
approximately 1440 watts. Or a 12 amp draw @120 volts ac. Older units will draw more current. This is the draw after start up.
the older furnaces would draw 700 watts plus depending on the size of the blower. the newer furnaces with variable speed blowers can draw as little as 100 watts
You can safely charge it with a 15 amp charger. You can also charge it with a 1 amp charger it will just take longer. Do not overcharge the battery.
Different phones will use different wattage. The screen size, the size of the battery, and the speed of the internal computer can cause the phone to draw more power.
The batter uses 5 Volts for charging and it takes 1 hour to fully charge your iphone which is 7 Watts.
There are many places where an iPod battery charger can be purchased from including directlly from the Apple store. Other options include Amazon and Tesco.
they use about 5 to 10 watts.
The current draw in amps mulitiplied by the voltage.
