A:AnswerThank you for your inquiry. The surge outlets would remain on if the power button is pressed off. To cut power to the surge only outlets you would need to disconnect the UPS's power plug from the wall. Unfortunately the option to turn them off would not be programmable on this unit either. I apologize for any inconvenience this causes.
A:AnswerYou are correct. The wattage they are stating is the battery backup portion. The less wattage drain on the battery , the longer the “run” time.
A:AnswerYou could choose power bank other than this one. This is for protect data lose when loss power/power surge. But after all you can choose this for the power supply for about 30 minutes at 50w, 5 minutes at 200w(It's not about math).
A:AnswerRe: APC-450. Has 4 battery-backed outlets plus 2 non-battery-backed outlets.
The 4 battery-backed outlets are spaced apart to accommodate "wall wart" or transformer-type plugs, at least those that are not really large.
The 2 non-battery-backed outlets are close together, so they will accommodate only plain (non-transformer) plugs.
A:AnswerI always use 1500 watt transformers that can handle a hair blowdryer for short periods. One of those dedicated to your computing equipment should handle the UPS during it's battery charging spikes for a few minutes anyway. I would recommend the 900 Va unit or larger, to get a more reasonable runtime if you are somewhere that the power is only on during daylight hours or some other schedule.
A:AnswerYes. It will provide power when the main power goes out giving you an opportunity to shut down your computer, or in your case, power the computer until the secondary power source turns on. That's the main purpose for these small UPCs.
A:AnswerThe UPS does not have a "UL" mark on it. It does have a "TÜV" mark. The NRTL does not require "UL", it only requires some type of certification. "UL" is not the only testing lab that is certified with the NRTL. "TÜV" is also certified by the NRTL.
