About this product

Product Information

High-performance surge suppression protects your computer from electrical noise and damaging power surges - even lightning.

    why the older model is better (CS 350)

    This is the older model designed to work with older (windows XP)software. It has less online bells and whistles when compared to newer models but I find it invaluable to protect my older electronics during brownouts and blackouts. It also has less of a chance of getting fried than the newer mdels. Thanks to a friend I've gotten a dozen APC and Tripp-Lite UPS devices from a company upgrading its electonic protection. Of all the devices I've used, the CS 350 (APCs) have all worked with a replacement battery and have held out for most of this summer - one of them is going through a 2nd, hot and humid summer with the same battery. If you don't mind getting older models that need new batteries, these are good deals. And if you're not putting your computers, laptops, networking equipment, ...

    Very good little plug and play UPS.

    Easy battery replacement and small footprint make this an excellent home or small office UPS. Just note that this system won't last very long after a power failure so, if you are looking for a 'bridge to generator' or 'bridge to safe shutdown' this is an excellent single user UPS. If you need 'continue to run' performance and longevity you might want to look at something a little bigger and if you are a multiple workstation operator this one is 'right out'... This model does not have an external battery connection but adding a secondary battery would not be difficult for a "GEEK" like me and that would give more time to make the shutdown decision.

    Reserve power is too limited

    It appears to perform pretty much is advertised but most people will find it in adequate as a reserve back up

    APC UPS

    Unit came in reasonable time and was ready to work out of the box. After charging overnight the unit supplied AC power for 1.4 hours with a 290 watt load
