I just bought an ASiair mini. While testing indoors, using a 12V 3A power brick, everething was fine up until after i disconected all the equipament from the ASiair and the current went to 7.5 A and the Total power to more than 90 W!. It started smelling burnt and i turned off. I tried to update the firmware and software trought 5V but it would still smell pretty bad. I tried a couple of time to connect again to the power brick but without success, always showing this ridiculous values. I checked the power supply with a multimeter and i was normal. What could be done about this?

...in fact, I had so many weird issues - and noticed so many others with weird issues - that I stopped using it altogether. And I haven't missed it in the slightest. Too freaking many weird issues. -chris

The power connectors are often the weakest link in this products. PCB mounted types.

 

If one had gone short circuit when you pulled the plugs, then I could imagine 7.5 A being drawn.

 

A bent pin, bit of swarf, solder flash.

 

If its under warranty, send it back, if not open it up - the short will be visible!

Thank you for your replies. it was in fact a short, I opened and it was melted. Now i'll try to send it back, if thats not possible i may send to some phone repair shop and see what can be done.

 

Thanks again!

I forgot to mention - the last weird issue I had was that the foul thing kept blowing fuses. I had already become annoyed because it didn't support one of its own cameras. (ZWO) Sorry for venting but I thought the truth might be useful. I sort of hope you send it back and run like that short is in your underwear...

As someone who enjoys using the AAP myself, I keep an eye on their support boards. The issues you described across those posts do not seem to be widespread. And a lot of the power issues people encounter are frequently (but not always) tied to power supply issues. Sometimes electronics just take a dump or arrive with issues.

 

The AAP, for a long time, simply employed a Raspberry Pi with a custom DC board. Pretty well-proven and rather good quality electronic device, that.
