What happens when you put a 1100mA into a 400mA plug?
You die
Can you use a universal ac adaptor set at 9v 400mA for a portable radio set at 9v 800mA?
No. Your portable radio needs 800mA to operate. Your adapter can only produce 400mA. If you make the connection the adapter will rapidly heat up and probably burn out.
Can you use a 9V 600mA adapter on a 9V 400ma scanner?
You can use any 9v adapter as long as the output amperage is rated higher than the amperage rating of your appliance so yes a 600ma adapter can be used to power a 500ma or 400ma appliance
Can you use a DC 7.2V 400mA transformer to power a small motor?
First, there are no DC transformers, transformers work on AC. If you have an AC/DC wall converter that has an output of 7.2 v DC, and a max current load of 400mA, then you can use this to power a DC motor that requires less than (7.2 x .4 = ) 2.88 watts of energy.
Can I exchange a 12V 400MA transformer with a 12V 1.25 amp transformer without damaging the unit?
if used for charging-NO if used for supply voltage-yes
What will happen if use a 12v 400ma instead of 12v 500ma?
i am not sure, BUT according to the answer in this post:Can_you_use_a_9V_600mA_adapter_on_a_9V_400ma_scanneryou need an adaptor of 9v and AT LEAST 500mA (assuming that the appliance draws 500mA)
Which is bigger between .5 amp and .400mA?
.5 amps equals 500 ma, which is much larger than .400 ma.If you meant between .5 amps and 400 ma, then again, .5 amps equals 500 ma, which is larger than 400 ma by a factor of 100 ma.
How do you work out watts for solar power?
Answer You need the Voltage and the amps it can supply then use the magic triangle formula that is Watt = Amps X Volts say 400mA 12 volt that will work out to .4X12 = 4.8 watt
Can you use 5v 1000ma adapter on a 45v 400ma device?
No you can not. The power supply output of 5 volts is under sized. There is no way that a 45 volt device would operate from it. You will need to find a power supply of 45 volts.
If a phone needs a 7v 900ma charger can you use a 9v 400ma if the voltage and polarity are the same?
The volts MUST match exactly, the polarity MUST match exactly, and the milliamps MUST be the same or more. The unit will use what it needs, even if to much is being offered. On the other hand, too few milliamps will BURN THE UNIT OUT! So on top of loosing your equipment, you could loose your life also ... since it is a major fire hazard! Clearly the voltage is not the same. The phone needs 7V, the charger is at 9V. Mismatching voltage will not work. Using a power supply with a maximum current rated below what is required will result in 1) the supply voltage dropping, and 2) the device generating additional heat. Such low power requirements do not present a serious hazard, fire or otherwise. However, the higher voltage will likely seriously damage the phone. Had the supply you chose been rated at 7V 400mA, the phone would likely still charge, albeit much more slowly.
Can you use a 9v 300mA adapter on a device that requires a 9v 400mA adapter?
No. The voltage rating is the same, but the lower current rating on the 400ma power supply might cause the voltage to drop way below 12 volts, and on some devices a lower voltage than it is rated for will cause it damage.
Hunting for a charger for a power pro craft 24v cordless drill Numbers on the side of it are CDD24D I have the drill but I can't find a charger any place Can anyone help me out on this?
Go to http:/www.hoyoa.com/eindex.html and click on products. You will see on the left a place to go to contact them. They made the charger however it may have been a limited run product for a certain company( Power Pro Craft CDD24D) and I don't think they store extras The power unit that plugs into the wall is a 27.0 volt charger: Model: BHY48-27.0V-400mA Input: AC 120v 60Hz 20w Output: 27.0VDC 400mA Date code 200510 If they can't help there just has to be somebody out there making on similar to it so you might be able to jury rig something that will work. I happen to have one which I purchased at Tractor Supply(tractorsupply.com). Good luck!
