If a maker or seller does not give pre-sales answers it's a bad sign. Also FSP is https://en.wikipedia.org/wiki/FSP_Group or a group of names we know for low cost only seems to be mid to low quality power supplies.
Let's see that model so we can read the manual about this.
I am thinking about buying a ups from Fsp Fp series.The thing I notice when I look at it's features, it is written:
Does it mean that it can charge itself even when it's in off-mode( in addition to be able to charge itself while in on-mode/running) or it can charge itself only when it's in off-mode/turned off?
Also what do you think about Fsp ups products,are they reliable?(I want to ask especially to people who are using or have used an Fsp ups).
