This is a big AMAZON goof! (not the fault of APC)
(so, on this product: APC is 5-STAR, AMAZON is 1-STAR)
This SUA750I is an "International" model.
(that last character in "SUA750I" is a capital letter "I" for "International")
The source voltage on this international unit is 220VAC-240VAC only.
So, the 110VAC-120VAC model is:
"APC SUA750 6-Outlet Standalone Smart Uninterruptible Power Supply (750VA, 5-15R)"
It's available right here direct from AMAZON and, as of this writing, is 25 USD less!
AMAZON needs to do at least three things regarding this and TONS of similar issues:
1. Provide a comprehensive, store-wide product rating system differentiating product quality
issues from those of shipping, vendor, AMAZON site I/F, etc. issues.
2. Exercise FAR more diligence in providing and maintaining accurate product
descriptions, tech specs, photos, etc.
3. Fix their VERY messy, duplicitous, inaccurate, illogical search engine / interface / data base(s).
AMAZON's Mr. JB needs to come in off the golf course, stop playing with his Kindle for a moment,
and apply a bit more biz & personal responsibility in this little billion-dollar, low-overhead,
easy-to-do-right, ethereal (can't see, can't touch) product market!
