    APC - Back-UPS 900VA Powerful but Trim

    This reviewer received promo considerations or sweepstakes entry for writing a review.

    This APC has 900 VA which is more powerful than any of my other APC products but seems more trim & streamlined. It was a bit of a challenge at first to get all of my cords in the available slots since a few of them had oversized connections. I especially wanted to make sure that my computer equipment was on the power supply side & the rest on surge protection.

    I bought this item for my daughter because she want to play her Casio electrical piano outdoors. A portable power will be necessary since the instrument equipped with no battery. 900VA will be good enough for around 1 hour so the capacity is good. The product is strong but somehow a little heavy for a 15-year-old girl. Also 9 outlets are truly not necessary even you use as UPS--an extension cord can do the job.
