I like it and it works great I have about 30 hrs of run time on power supply at 2.25 amps at 1 12volt circuit so I'm not stressing the unit at all when 30 amps is the max rating. Nice power supply for what I use it for and plan on adding 2 more amp load to it soon.
Update; 10-14-2020
Still working great, I added 1 more amp to the load so I'm at 3.1 amps now so 10% of max load and the fan is louder now. I have to relocate the power supply to a isolated spot so I can't hear it now. Yep the fan is getting to loud at 10% of max rated load.
Users should understand electricity and that they need to take steps to provide adequate protection - like shrink wrapping your connections right up to the board, making sure the provided cover is always in the down position and that you do not exceed the load limits of the unit. Actually, not exceeding 75% of the stated limit is a good idea, providing some margin of safety.
Time will tell if this unit holds up but if it does, it's an inelegant but very inexpensive solution to the converter problem. You can buy name brand converters with on/off switches, shielded plugs, meters and fancy cases but in the end, they all do the same thing - change 110AC to ~12V DC. This one seems to do it very cleanly without any variance in the output. I'm not sure I'd hook it up to a $1,000 worth of HAM radio equipment but for my $100 chargers, it's just fine.
Cons: The noisy cooling fan runs continuously when AC power is on
When I purchased this supply, the description said that the cooling fan was thermostatically controlled. It isn't. The fan runs when the supply is powered up, regardless of the load. The description does now say that the fan runs when the supply is used. Some of the reviews for this unit say the fan runs only at high load, apparently customers have received different versions at different times.
That said, I'm using this to power an amateur radio, and haven't gotten any comments about switching noise getting into the audio, nor do I hear any switching noise in the receive audio. The acoustic noise from the fan is loud and relatively high pitched, and very annoying for my purposes. If I hadn't waited past the return eligibility date I would have returned it. I'm installing a thermal PWM control for the fan that I hope will remedy the noise problem. If you're considering this approach, be aware that the 60x60x15 fan is a 2 wire fan with no provision in the fan itself for PWM or tachometer.
