In most ways, the Jackery 1000 Plus does exactly what I bought it to do which is provide power to my modem and router in the event of a power outage. The one feature I thought I understood is the EPS Mode. The EPS mode is purported to provide the functionality of an uninterruptable power supply. What I learned the hard way is that I did not read enough about the EPS mode to know it would not serve 100% as a backup UPS. I also learned after setting the Jackery 1000 Plus up and using it in EPS mode, that there is a fan and electronics inside it running continuosly to power the loads. The AC outlets do not function in a passthrough manner in EPS Mode. The unit shuts off after a period of time if power drawn by the loads is below a certain value. That resulted in my modem and router being turned off while I was watching a streaming presentation on tv. So, for me, the Jackery 1000 Plus is nice, but it is a miss on the EPS mode functionality. It would be WAY more useful if the AC outlets functioned as passthrough in EPS Mode and did not turn off if load power failed to meet a minimum criteria.
