While youre waiting for these to come into stock, you can buy a 25A 13.8V PSU with 110-250v AC inputs off **** for 34.00 POSTAGE FREE (to UK). Its a chassis unit, so it just needs putting in a ventilated box. We use these at work for CCTV, so I know they're good

I can't get more than 4A constant out of my power supply. I have tried multiple. I claim 30-35A but you will get a voltage input error if charging at over 4A.

has anyone ever measured the voltage between the housing (protected earth, use a screw as reference point) and one of the 12V power outlets of the power supply?
mine shows 120V AC !!! while turned on
even in off osition there is 35V AC
to me that sounds anything but healthy...
curious what you measure...

Great PS for my two FMA 4S chargers * 3C (4 amp limit) however when attempting to charge a 4S 3700 Lipo * 3C on my 10S FMA charger the PSupply kicks off until I reduce it to a 2C rate approx 6.5 amp charge. The 10S FMA charger is able to charge up to 11 amps on a 3C setting. Question is - is it possible to use both outputs of the PSupply to get to the 350 watt output???

It sounds like your PS topps out at about 130 watts (per FMA Direct the charger is 81% efficient. I have only tested mine to about 240 watts, without a problem. But, as stated above, I did have to add a load to the output of the PS to make it stable.
Good luck

Note, the two outputs are soldered together to the same source ** no advantage to using both outputs.

Like several other people, when the A30 turns on most of the time I get a flashing green LED and not enough power to operate any charger. I tried running just some large 12v fans I use for cooling packs, and all worked well with a solid green LED. It seems like there is not enough load using the Quattro or other charger. So, I put a 4-watt lamp (low voltage garden light) on the output and it now works perfectly. If you LED flashes, try this fix.

I'm able to charge a 3S 3300mah Lipo to 10+amps on a 3C charge (10S charger), but limited to a 2C charge (aprox 7 amps) on a 4S 3700mah Lipo with a 10S charger on a 3C setting this PS kicks off - not related to heat.

My I-charger draws 12AMPS from a power supply to charge a 6S, 5AMP lipo at 1C charge rate. My turnigy batteries are 2C, so thats * 24AMPS to charge a Lipo (6S) battery at 10AMP charge rate.

Night flights comments are very important. This is a 300 Watt power supply, not a 25 amp power supply. The same applies to the chargers. They are absolutely perfect (1010B+ etc) but they cannot charge a ten cell pack at 10 amps. That would be 420 watts. Not possible. The charger is a 300 watt unit and the power supply is made to match it. Also unless your using LiFe packs you cant charge above approx 5 amps for most packs. 1C is still the recommended maximum to get good cell life.

You also have to consider the losses in charger. power supply should be about 10% more powerful than actual charging power. Your chargers max power rating*1,1= required power supply

Just a heads-up for anyone not so electronically minded. The power supply's rating is for exactly what it says: 25A at 14V. If you are charging larger packs than 14V (5S+ lipos) then you will need to downgrade the max current accordingly. Thankfully this will still be in excess of most chargers and packs, so there should not be any concern, but I've seen a bad review of the simple 12V/5A power supply that was actually due to the user's lack of understanding of transformers.

The pack's voltage and the power supply's voltage are unrelated ... the charger takes care of increasing the voltage. You can charge a 10s pack on a 14V power supply. What is important is Watts... 14v x 25A = 350 Watts ... so your charger(s) cannot input more than 350 Watts. This is a great value.

Night Flight: I absolutely agree. However, some people seem to think "wow, it does 25A!!!, great - I can charge my 12S pack at that rate!". My point was that if they have a higher output voltage than input, the current needs to be downgraded ON THE OUTPUT. Your explanation of power is the "nuts and bolts" of how it works, where V.I on the input = VI on the output, less a little for the device itself.

If you want to charge a 10S:
Max charging voltate for 10S= 10*4.2V = 42V
Max output power = 350W/42V = 8,33A In this case, you'll have a current input of 25A and 8.33 A at the output! In pratice, you'll never get this values because you have losses, but you'll have something aroud that!

The label on th epicture says: "Quadruple Outputs". This would mean 4 outputs. Beside the 2 screw lock outputs there are probably 2 non-visible banana plug outputs.

I doubt it has quadruple outputs. I'd suggest the good folk at HK have simply counted the number of outlet ports and come up with 4: 2 x red and 2 x black.

Four binding posts in total on the A30.Two red and two black.Each binding post can accomodate two banana jacks.One in the very end and one off of the side of each binding post.That makes for a total of 4 red and 4 black charging wires in total(a possible 4 chargers pending on load requirements).

Hello
Both my diet A fan 30 does not work even when fully loaded.
Thus, it overheated and stopped working properly.
It cost me 35 dollars to send this article to a defective price of 49.95 dollar
I read several reviews on the A30, I see there are too many complaints.
I do not understand that hobbyking continuous power A30 Buy from as low quality.
