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.

What does 800MA mean on an adaptor?

The term "800mA" on an adaptor indicates its maximum output current capacity, which is 800 milliamperes. This means the adaptor can supply up to 800mA of current to connected devices without exceeding its rated capacity. If a device requires more current than the adaptor can provide, it may not function properly or could be damaged. Always ensure that the current rating of the adaptor matches or exceeds the requirements of the device it is powering.


How long last 4000mAh battery?

The duration a 4000mAh battery lasts depends on the device's power consumption. For example, if a smartphone consumes about 400mA per hour, the battery could last around 10 hours (4000mAh ÷ 400mA). However, if the device uses more power, like 800mA, the battery would only last about 5 hours. Therefore, actual usage time varies based on the specific device and its usage patterns.


What does 9 volt 800mA means?

A 9 volt 800mA rating indicates the power output of the device, with 9 volts being the voltage supplied and 800mA (milliampere) being the current capacity. This means the device can provide a continuous current of 800mA at a voltage of 9 volts.


Can you use a 9v dc 1000ma adaptor for a device that has 'power input' of 15v dc 800ma?

A: Disregarding the fact of different voltages there is the power to be concerned 9v x 1A = 9W, 15V X .8 = 12W. THE DEVICE WILL BE UNDER POWER.

What does 800ma on a 12v transformer mean?

The specification of "800mA" on a 12V transformer indicates that the transformer can supply a maximum current of 800 milliamperes (0.8 amperes) at a voltage of 12 volts. This means that any devices connected to the transformer should not draw more than 800mA to avoid overloading the transformer. If the connected device requires more current than the transformer can provide, it may lead to overheating or damage to the transformer.


What does 800ma mean?

Well, hello there, friend! 800mA stands for 800 milliamperes, which is a unit used to measure electric current. It's important to understand how much current is flowing through a circuit to ensure everything works properly. Just remember, when it comes to electricity, it's all about finding that perfect balance to create something truly beautiful.
