Robust little power supply that runs the CCTV
we now have 3 of these units running our CCTV system. the original power supplies gave up after about 2 years. these ones are good replacements. they hand the load well. do not get too hot. (just warm to the touch) . each PSU (power supply unit) has a 4 way splitter on it so it can supply power to 4 CCTV cameras. they do the job really well. giving a nice steady power output. even at night when the infra red lamps are on . good product.

Works as advertised
Bit pricy but there’s shockingly few AC adapters available on amazon given how common they are.I’ve had no issues with it thus far. Including accidentally spilling coke onto the brick. Not a heavy amount but enough to be concerned. And although I unplugged it for a few minutes and dried it just to be sure, it worked fine without issue.

Purchased to power a SkyRC Mini
I got this to power a SkyRC B6 Mini battery charger which I was surprised to find when delivered doesn’t come with a power source. The manual states to use 12v with minimum 6 milliamps, this I thought would be perfect as 8 milliamps and it is, powers it up great. The product seems well made with a blue power on warning light, be great for many applications.tj
