<div dir="ltr"><div>While I'm no expert with picking UPS models, I can say from experience that you need to be sure of your voltage draw per UPS device. I had a smaller, old UPS that I stuck under my desk a while back after I bought a nice big new one to be my main device. A few months later I bought one of those little desktop coffee warmers and plugged it into a desktop power bar. Turns out that when I turned on the coffee warmer the drain (while warming up) was daisy chaining its way from one power bar to the next until it got to the old UPS and set off the alarm. Now those of you that know me know that my hearing is pretty much shot, so I never heard the alarm, but all the women in the house went nuts every time I tried to warm up my coffee. It took us weeks to figure out where the noise was coming from...</div><div><br></div><div>Lesson learned: the right UPS can save your family's sanity!</div><div><br></div></div><br><div class="gmail_quote"><div dir="ltr" class="gmail_attr">On Tue, 23 Jul 2024 at 10:44, Khalid Baheyeldin <<a href="mailto:kb@2bits.com">kb@2bits.com</a>> wrote:<br></div><blockquote class="gmail_quote" style="margin:0px 0px 0px 0.8ex;border-left:1px solid rgb(204,204,204);padding-left:1ex"><div dir="ltr"><div dir="auto"><span class="gmail_default" style="font-size:small">Hello all ... <br></span></div><div dir="auto"><br></div><div dir="auto"><span class="gmail_default" style="font-size:small">Had a bad experience with the UPS yesterday </span></div><div dir="auto"><span class="gmail_default" style="font-size:small">(more on that below if you are interested), but <br></span></div><div dir="auto"><span class="gmail_default" style="font-size:small">the result is that I now looking for a UPS to replace </span></div><div dir="auto"><span class="gmail_default" style="font-size:small">the one I had.</span></div><div dir="auto"><span class="gmail_default" style="font-size:small"><br></span></div><div dir="auto"><span class="gmail_default" style="font-size:small">The old one is a 1200VA APC Back-UPS that was </span></div><div dir="auto"><span class="gmail_default" style="font-size:small">over 15 years old.
