The Max 625 VA UPS comes in two models, the SLK (sleek)
and the NRL (normal). The NRL, has three outlets and with a flat, rectangular body,
manages a very low sleek profile despite a larger foot print and you can slip it under
your table. The SLK’s name is a misnomer. It has a large, boxy body that despite a
smaller footprint is difficult to store under the tables and has only two power outlets.
You also run the risk of accidentally switching it off. Other than these, there was no
apparent differences between the two models’ performance. For the ratings, we tested
the Max 625 SLK.

increasing the back up time. During our tests, we did not use external batteries.
Interestingly, the Max is one of the few UPSs where the
battery float voltage is within allowable limits. It also lowest price per VA
