A:AnswerIf you mean as an unplugged "battery," the basic answer is yes. However, it is not the intended use of this product. The product is a bit on the heavy side and has an audible alarm in the event it loses power and is being drained. This is intended to provide emergency power to critical electronic equipment in the event there is a short-term loss of electricity.
A:AnswerThe current models do not have the ability to communicate power loss to owners via a smartphone or other device. It has an audible alarm so anyone in proximity to the device can hear it. If you only have a modem and router plugged into the device, you should get around 20-30 minutes of run time when electricity is out. That time is dependent on the activity level of the two devices and the age of the battery back-up. Like any "battery" it degrades over time and will eventually need to be replaced.
A:AnswerThere are a few videos online that compare simulated sine wave versus true sine wave. Basically, a simulated sine wave looks like a jaggy version of a sine wave. Some videos compare these backup power units and show what sine waves they produce.
A:AnswerI think you are thinking this is a smart device? It works like a surge protector, but when the power goes out, it will supply power to your required application that works within the parameters of this device.
A:AnswerThank you for answers. But needed a way to turn off power as there are a few USB attached devices that remain powered on (including speakers with blue lights), even after PC is shutdown. I am leaving UPS on as recommended - but have a power strip plugged into it to kill PC power after shutdown.
