Can I use a 15vac 500mA instead of a 15v ac 600mA?

Answer 1

Yes, it should work. The device being charged will only take the amount of charge it needs and all the 300 milliamp rating means is that the charger provides an additional 200 milliamps of current.

Be sure though, to make sure the plug polarities match the one of the original and as long as you are sure the voltage rating is the same, you should be OK.

You may find that your device will charge a bit faster than it did. One other thing you need to know though. If the original adapter puts out 9 volts at 100 milliamps DC and the other adapter puts out 300 milliamps AC, they aren't compatible, and will most likely burn out your device being charged.

Answer 2

Yes. The current rating should be the same or greater than the original. This means the adapter can supply up to 500mA; In your case it only needs to supply 200mA, so it is more than up to the job.

Answer 3

Maybe, maybe not.

The 9 VAC supply is probably being rectified to produce DC inside the equipment.

If so, it's producing around 13.5 volts after rectification.

If the equipment "expects" around 13.5 volts, but only gets 9 volts, it may not work.

BUT - if the equipment is designed to ONLY accept an AC input, then applying a DC input may well damage or destroy the equipment.

So, that answer is that you MUST know what the equipment is doing with the 9 VAC input.

1. If it's rectifying, it may not work as the 9 V is less than to 13.5 V you would get after rectification.

2. If it's *not* rectifying, applying DC may damage or destroy the equipment.

Answer 4

The adapter's output voltage should match that of the load it is going to supply, and its current rating should exceed that required by the load. So the answer is no.

Answer 5

If the original 6 volt 300mA adapter is a DC output adapter, NO the new AC output adapter will damage and possibly destroy the device being powered.

If the original 6 volt 300mA adapter is an AC output adapter, the new AC adapter adapter will probably work fine.

Not only does the output voltage (should be same) and output current capacity (should be same or larger) of the replacement adapter matter, but the output waveform (AC or DC, should be same) and polarity if DC output (should be same) matter for proper operation of the device and to avoid damage to the device and/or adapter.

Answer 6

As long as the device that is plugging into the adapter does not draw any more that 300 ma it will be fine to use. If the device that you are plugging into the 300 ma adapter draws more that 300 ma it will make the adapter overload. This overloading will create heat and could eventually burn the adapter's internal wiring to an open state and it will not work any more.

Answer 7

Since the voltage is similar, that shouldn't pose much of a problem. With a LOWER than requested voltage, you don't run the risk of burning the equipment. you connect However, it is possible that it doesn't work at all.
With respect to the mA, you should check how much mA the device you want to connect requires. If it requires more than 300 mA, you might harm the adapter.

Answer 8

Yes, as long as the polarity and physical connectors match.

Answer 9

Yes. The voltage matches, and the 700mA adapter can deliver at least 300mA. The key is to match the voltage, and at least match the current capacity.

Answer 10

Maybe, maybe not. If the equipment that's hooked up to the adapter really need 800 mA all the time, expect the 500 mA unit to overheat and fail eventually.
