## Description

Product Description

Review: Awesome Product - I've been using the CRUST Mini UPS for a few weeks now, and it's been a game changer during power cuts. It switches seamlessly to battery mode without interrupting my internet connection. The backup lasts around 4 to 5 hours with my router, which is more than enough for most outages. The build quality is compact and solid, and I appreciate the smart voltage detection (9V/12V), no manual adjustments needed. Setup was simple, and it works silently without heating up. Highly recommended if you want uninterrupted Wi-Fi at home or during work-from-home sessions. Worth the price!
Review: The Mini beauty - truly adorable on my desk - I wanted my WiFi router work uninterrupted during power cuts - most of my power cuts only for a minute or two - but this interrupts my work by about 10 minutes each time it happens as the router needs to restart. I was looking for a simple device that can help me get through this issue. Then I found the CRUST Smart Mini UPS. The perfect solution. It is an awesome "in-line" mini device that is doing it's job effortlessly. Very Easy to connect. Smart enough to detect the voltage of the application it is supporting (also has an indicator on it showing which voltage it is auto serviing). Came with a switch to tun-off the device when don't need to run it. My money's worth. Go for it. Highly recommended.

### ⭐⭐⭐⭐ Good Quality Router UPS
*by A***R on 6 August 2024*

My experience : - Seems to be working fine with my 9V router - No switching lag observed - Can be easily mount on a wall nail - Installation is a DIY - Build quality is good I haven't tried fully draining out the battery but hope to get a backup of around 3 to 4 hours. Again it depends on the router input current and can vary from router to router. Overall it's a good product.
