This is a great back up for modem and router. Power outages in this area are frequent and short (normally less than 2 hours). This small unit can keep WiFi router and modem both running for as long as has been needed in the past 2 years. Great, inexpensive solution to keep the internet connection during an outage.
Many thanks to Conwintek Mini UPS for resolving the power outage in this area.

Reliable, very useful! Excellent Customer Service!

I have wanted a way to keep internet on during power outages for the security system to transmit alarms for about a decade. At the same time, the wheelchair also needs an uninterruptible power supply to keep the alarm system in power. Thanks to Cowintek UPS for solving the power supply problem in the nursing home.
