In Battery Backup (UPS)

Well packed manufacturer packaging. Very clear multi-lingual user manual that is well worth the time reading the few pages in your chosen language. Very clear warning markers attached to UPS. Very difficult to install and use this unit without seeing the warning marker to connect the internal batteries. Silent operation; it does not have any fans on/in it that I can tell. Novel "master slave" outlet pairing. Lose power to the "master" device and the "slave" device turns off immediately. The manual tells me this feature is disabled by default, but read the user manual carefully to fully understand it's operation.

Bought because the electric work in my new house is unreliable. Until I fix my house I bought this and it has saved me from so many under voltages I almost lost count. Bonus points for saving me through two thunderstorms that killed my electricity completely. I couldn't have bought it at a better time! It gives time for how long the battery will last (depends on how much current you're drawing). Kept my computer on until the electricity came back on. I feel so relieved! Plus pure sine wave is better for your sensitive electronics such as a PC than simulated sine wave. The product feels super solid and you can connect it to your PC's usb to get a system notification icon on how long the battery will last. Amazing.

This battery is awesome. I replaced a couple of smaller UPS's with this one in a telco closet.. love the fact that i can just plug this into our comcast business modem and it goes to the net and does it's thing in the cloud. This did come with a 20Amp plug so i had to change it over to the regular straight plug.. but you can get adapters for those.

Almost enough wattage for a UPS design that I was seeking way before purchasing after finally realizing I might need this much wattage or more as well as this design and the the only problem was that it just wasn't going to be enough wattage to properly shutdown all the connected equipment and that it didn't have all the possible connections I was still seeking for the type of UPS I needed this to be.

Silent! My last UPS (Tripplite) could be heard two rooms away. Can't hear this one sitting right next to it. It's really stable when used in tower orientation due to the battery being in the bottom. Construction is really solid.

After a nastyy rain storm the power went out all throughout the house. I had forgotten that my pc was on. I heard some beeping coming from the kitchen and my pc was still running, After it shut itself down automatically I sat down to look at it and then it hit me - - I need one more for my other pc.

LED Display ~ Shows current load of devices, Battery status, And current outlet voltage status. Black case (And yes that's important to me) Connects to PC thru USB for graceful shutdown Mute button for alarm, Finally! Thanks for this APC

Easy to use Has enough outlets
