Review: Perfect for keeping the Internet on - Wanted this to keep my router and modem on during power outages and worked great! My TV however still shut off, but I think it's due to it being cheap and doesn't have a good power supply. However my main concern was my internet staying on. I've seen some reviews about people using this for a PC and it not working. Well, this shouldn't be used for that, you need a more powerful UPS. This item is great for smaller things such as a router or a modem, maybe a small fan. I definitely recommend this!
Review: Quality product at a good price - Excellent choice for a small back up. Use this for my net/wifi. Doesn't need much power but keeps the net from disappearing.

### ⭐⭐⭐⭐⭐ Keep your Internet alive long enough to sace your work
*by W***S on March 21, 2026*

Supplies enough power for Fiber internet, or Bee link computer Gives you time to save your files and shut down properly. May need a larger unit for flat screen TV. Power surge or Brown out can kill a Roku TV fast. I live 400 feet from a substation. When the breakers open and close, it sounds like a 12 gunge shotgun going off.
