The increase in current (assuming resistance is the same and increase in voltage will lead to an increase in current) will fry your portable radio.

Can you charge a car battery with a motorcycle battery charger?
Unless it's an old vw bug, cars usually run on a 12 volt dc system nowadays. Motorcycles often run on a 6 volt dc system. Different systems require different charging voltages so you won't ever be able to charge a 12 volt car battery from a 6 volt motorcycle battery charger as the output voltage would be way too low. However, if you can set the battery charger's output to give either a 6 or a 12 volt output, then you must always remember to set it to 12 volts if you want to use it to charge a 12 volt car battery.
Which 12 volt bulb will draw the most current when connected to a 12 volt battery?
The bulb with the lowest resistance. Current = Volts / Resistance
Can you run a 12 volt ac water pump with a 12 volt dc adapter?
No. You need 12 volt AC to run a 12 volt AC motor, not 12 volt DC.
Can we run a 110 volt 100 watt DC motor with 12 volt 5 amp power is the same so it should run?
Sorry, won't work. You need a 110 volt supply.
How many kwh are used by a 12 volt battery?
Every battery has a rated life in kilowatt hours or ampere hours. There is no way of knowing what battery you are referring to. To supply one 1000 watts (1 kilowatt) of energy at 12 volts, the battery must supply 83.33 Amps at 12 Volts. If battery supplied 83.33 Amps for one hour then 1 KWh would be the result.
Will it hurt a clock which is meant to run on a 1.5 volt battery to be run by a 6 volt battery?
it can get really hot and burn the circuit
How can you run a 16 volt in-car DVD in a car with a 12 volt battery?
Go to Radio Shack and get a plug in convertor (plugs into the cigarette lighter socket) and run it off of that. For about $20 you can get a selectable voltage item that should do just fine.
Can a 12 volt motor turn a mini alternator to charge a 12 volt battery that runs a car stereo?
If you can get the battery to run the motor, write it up in a science journal. You'll be rich. Sure but what are you going to use to power the 12 volt motor? You will have to use another battery which you could just use to power the radio in the first place.
Can you use a 3 volt battery to run an 8 volt motor?
You can but the motor may not run, however you will not burn the motor.
Can you run 2 12 volt trolling motors simultaneously off a single 12 volt battery?
Yes but you will deplete the battery quickly.
Can you use a 16 or 18 volt battery in a 14 volt ryobi cordless drill?
Absolutely not! It is a 14 volt drill. Use a 16 or 18 volt battery will destroy the drill in short order. It will run but not for long.
Can 2x 9 volt battery run a 60 watt globe?
No
Can you run 220vac on 120vac on battery charger?
Your question is confusing. First off a battery charger puts out DC voltage not AC. If you are asking if you can run a 120 volt battery charger on a 220 volt circuit the answer is no you cannot. That would destroy the charger.
How long can you run a box fan off a car battery?
Unless it is a 12 volt DC box fan you cannot run it at all. If it is a 12 volt fan the time it will run depends on it's size and at what speed you run it and the condition of the battery. All you can do is try it.
Can a 9 volt battery charger be used to charge a 4 volt battery pack?
Sort of, but any automatic cut-off won't work. You run a real risk of overcharging the battery and damage it.
Does the 1981 Kawasaki KZ750-H LTD run on a 6 volt battery?
No. It calls for a 12AH 12v battery.
How do you wire 3 batteries together to make 36 volts?
Take 3 twelve volt batteries Run the + of battery #1 to the - of battery #2. Run the + of battery #2 to the - of battery #3. Use the + of battery #3 for your positive feed, and the - of battery #1 for your ground.
