## Description

Product Description Starwatt Mini UPS Installation Steps Switch off your Router Main Power Supply. Disconnect your Router from Power Adapter. Check the Input Power requirements of your Device. Check the output power of your Device's AC Adapter. Connect the Starwatt AC Power Adapter provided in the package to “IN” side of Router UPS. Connect “OUT” Side of Router UPS with supplied Cable to your Router Power Input. Router's input voltage must match with UPS output voltage. Repeat the above steps for Dual Output setup. Switch on the Main power supply. Switch "ON" the Router UPS toggle switch. Now your router should boot up.

Review: Quality and performance - For this price, it does its job great, and it is hard to find a UPS with two or three outputs. Otherwise, we would have to use converters. The plastic and power adapter provided feel a little bit cheap, but it does its job excellently. I am using it to power a 9V1A ONU and a mesh node with 12V2A, and I am getting around three hours of backup. It only have a 5800mAh battery.
Review: Good Mini UPS with Decent Backup (Initial Use) - I recently purchased the Starwatt Mini UPS and have been using it for a short time. During a recent power cut, the UPS provided around 3 hours of backup, after which the main power supply was restored. Because of that, I couldn’t test the full backup duration, but the performance so far has been satisfactory. The UPS switched over seamlessly during the outage, and my device stayed powered without any interruption. The build quality feels decent for the price, and it’s compact and easy to set up. Overall, based on my initial experience, it seems like a reliable mini UPS for short power outages. I’ll be able to comment more on the maximum backup time after longer usage, but so far, I’m satisfied with the purchase.
