The unit I am using it on is 9V 300mA. Will this blow up my unit or will the unit just draw 300mA from the power supply? Thanks

Not sure about that, all I know is that the plug got super hot and started smelling like something was burning. So I returned it. Just be careful.

I'd recommend find a 300mA multivolt adapter ... this one can cause damage to your unit because it is less than 3 watt.

I don't know if the question is regarding voltage coming into the home or actual voltage from the outlet, however the unit should not draw more power than the unit demands. It should be OK.

Hello Peggy, If you Plan to use a load that surges to the 3,000 watt rating then you must use a 250 amp fuse or resettable circuit breaker for the Input side. This unit works well up to 1,000 watts It does not perform well on large start up motors like a Vacuum cleaner. I use this unit for small loads that require a pure sine wave. Mike

My husband is an electrician. He said it would blow it up. It works with 120. : )

If it see any trouble it will kill all power. Love mine! I'm sure it has saved me money from bad power.

it will burn up,you could use a 12v. transformer to reduce the voltage to make it work.

It needs a special transformer that outputs 32 to 36 volt dc 3amps = 100wts i dont know any other way. I just follow mfr spec instructions hope this help . You may also need a heat sink and a cpu fan attached to the heat sink so it wont over heat and burn out.

it can run from as low as 5v (at least 1amp but 1.5amp is better). 9v works fine. 12v is what is listed but since it works at 5v, 12v seems a bit too high to me (extra volts are burned off as heat; never a good idea). I suggest using a good strong 5v dc psu.

Not sure I can help you with your question. I used this unit to run some portable fans at a dog show one day. A few months later I got the unit out to put air into an exercise ball and the unit caught fire. I called the company I bought the unit from and was told it was past the 90 days so too bad. Personally, I wouldn't recommend buying it.

IT Does but its not meant to be user serviable... its a 250 amp fuse. I would use a 200 amp external fuse or circuit breaker as system protection. that will pass 2 KW even at 10 volts DC so the fuse should blow above that level of power.

Mine has a 15 amp fuse, I have run this temporarily overloaded and shorted resulting in a blown fuse, with it surviving. I did however have one unit fail, after running it overloaded for too long, from excessive heat.

Also don't forget, if you need 250ma and something puts out 300ma that's OK because the device you have will only pull the ma it needs, no more no less, just what it wants. Kevin P

Power = Volts x Amps... So 300 is more than enough. Personally I bought the 500 Watt version because I use it for many things

You supply the input fusing. It's rated at 3000W peak which would require 250A. 250 slow blow to 300A would be appropriate.

I ran a small 400 watt inverter off of this unit to operate a laptop computer up on the dash of my motorhome while underway. Worked fine but the key of course is having it on a properly fused 12 volt circuit matched to whatever device your trying to run. This unit has a 15 amp limit. Use it improperly and I'm sure it would burn up.

The supply brick says 0.35 max (amps, presumably). It only puts out 3 A at 5 V, so the actual draw is probably closer to 0.2 A.

I am an electronics geek so here it goes. I don't know what u mean about the ma input but you can use any standard wall outlet. This unit is great and puts out a very stable 300ma at 3, 4.5, 6, 7.5, 9, and 12v DC. If you need 4.8v 5v is the closest it would get. However you could get a 4.8 voltage regulator and run the 5 thru that and the output would be fine. You could just solder the components onto a proto type board and there you go, it would work. You could get the parts at a Frys or online. But this unit will not put out 4.8v right out of the box, it has no setting for it. I don't know what you are using it for and if the 4.5v is exact, because 5v is really close, but that's it. I really hopes this helps you. Please keep in mind I do not think there is a standard AC to DC that will output something exact as 4.8v, that's pretty specific. Again I hope I helped you. Have a great day. Kevin P
