I bought two of these for powering my 16 security cameras. They replaced another one that failed during a local power failure due to high winds. I banged the old one around to get it to work again while waiting for these to arrive. It had some issues with providing enough power to run the IR led's for night vision on some of the cameras. When these arrived in a few days, I plugged the cameras into them, then plugged the power blocks into the wall and all my cameras worked again as they were designed to do. I'm happy with my purchase, the price was reasonable and the power bricks do their job well.This power supply works pretty well. However, the jack barrel is only 11mm long which may be an issue with some applications. There 11mm jack barrel length was not stated in the specifications.Works for the 4moms bouncer 12v 3a which we lost in the move inter state.. working well for now will update review if it stops working.. not getting hot or strange smells..Worked well before it died at around 60 days with less than 100 hours of use. Awaiting response back about a warranty replacement.Product works great for my 5g modem / router.I give this power supply a 3 star, 5 star cause it really works great for my battery charger, but 1 star oh how horrible it came in the manufacturer packaging, look like it was a used item, box crushed and opened up on both ends. This power supply looks like a carbon copy of the one that came with my battery charger, so it does the job, I am ok with it.It died after 4-5 months. Light doesnt turn on nor does it power my device. I think short circuited. I used it by itself to avoid short circuiting but still ended up not workingSome products require higher amp outputs and this one works fine
