provides 850mA @ 9V, not 1A
Materials appear to be higher quality than similar power supplies.The output is rated at 850mA @ 9V, so do not purchase for devices requiring 1A.The power supply has a bright blue LED.

Concert 9v batter powered safe to power adapter. Beware of bright blue light on the adapter.
This worked very well to convert the 9v battery powered GunVault SpeedVault to adapter powered. Took one star off for the most horrendous 1000 lumen blue light on the power brick that can’t be turned off. You can guide ships to shore by that thing. What idiot engineer thinks that people would want that in their rooms? Anyway, can’t comment on longevity but so far so good

This power supply does not meet their specs
The description says 1A output but the supply they sent me is marked 850mA output. Now I have to send it back - waste of my time.
