CyberPower CyberPower CP350SLG Standby UPS 350VA 255W Compact

They work well on your TV and sound bar ect.

Great Unit for the price! Small, sleek, and very easy to install- just plug it in and charge up! There are six plugs, three with battery backup and three normal.I live in a spotty area in the grid, the power's gone out three times since I've had this and the battery backup kicks in just as it should! No hiccups, and it can run my internet for about 30-40 minutes.Overall, reliable, tried and tested, and totally acceptable for the price. Does the job.

I want to make something abundantly clear up front: This is NOT the UPS (for the uninitiated, that stands for Uninterruptible Power Supply, which is essentially a battery backup unit for whatever you plug into it) to buy for your desktop computer. Your desktop computer, screen and peripherals probably draw almost that much power combined when they're all in use, and the 350 volt-amps of output that this unit can supply will not run them very long, assuming the UPS doesn't just cut out as soon as the AC power fails. I wouldn't consider anything smaller than a 700VA UPS for a typical desktop computer setup. Besides that, this particular model lacks hardware and software to communicate with your computer and trigger an orderly shutdown when the battery power runs low.However, this unit can be ideal for many other kinds of equipment that you want to keep up and running when the power fails or hiccups. I bought two of them for a college dorm's wi-fi equipment. One UPS powers a cable modem and wi-fi router, and the other powers a wi-fi extender. The reason I decided to put these pieces of equipment on battery backup was because all were malfunctioning frequently, most likely due to surges and ebbs in the aging building's electrical system, or maybe due to students' tendency to trip circuit breakers. (Did you ever live in a dorm where students didn't trip circuit breakers with annoying frequency?) 350VA UPSes like these can run low-voltage network equipment for hours. Since I installed these units, the only times I've had problems with the dorm network equipment has been when the cable Internet company service has dropped.

Plug your Amazon Echo Show into one of these, and also your home network router into another one, and you don't loose Alexa during a brief power outage. Great for small devices you want to keep up - don't put a monitor and desktop on one - buy a bigger UPS for that!

Compré el UPS de 350VA, pues sólo lo requiero para respaldar mi módem de internet ante intermitencias en la corriente eléctrica, al recibirlo lo dejé cargando por más de 8 horas, luego hice prueba desconectando la UPS de le corriente eléctrica y conecté un ventilador de torre en su velocidad más baja y el respaldo duró casi 3 horas, los pitidos de la UPS se producen cada 30 segundos cuando esta funcionando en modo respaldo, cuando si está conectado a la corriente eléctrica no produce pitidos, me parece un buen respaldo y me gusta que su tamaño es pequeño en comparación con otros que son enormes. Lo recomiendo.
