CRUST Smart Mini UPS for WiFi Router and Modem. Upto 4 Hours Power Backup. Replaceable EV Grade Li-Ion Battery. Supports 9V & 12V Routers, CCTV, Set Top Box, Access Control

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!

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.

The battery was supposed to have a long lifespan, but it has died after just 17 months.

Such a disappointing product. It stopped working in just 10 months. My Resonate UPS has been running perfectly for more than 5 years. This one is still under warranty, so I wanted to claim it. But after reading the terms, it looks like the process can take more than 15 days, the claim can get rejected, we may have to ship the item ourselves, and pickup of the replacement has to be done from their hub. On top of that, the shipping cost is also on us. Given all this, I would rather buy another UPS from Resonate or some other reliable brand. My advice is to avoid this brand entirely.

The CRUST Smart Mini UPS for my router has proven to be an excellent choice. During a recent power outage, it kept my router running for a full 4 hours—plenty of time to handle most situations. The setup was straightforward, and the compact design is a nice touch, fitting neatly in my space. Pros: Performance: Provides 4 hours of backup power as advertised. Ease of Use: Simple and quick to set up. Build Quality: Sturdy and well-constructed. Value: A worthwhile investment for continuous internet access. Overall, the CRUST Smart Mini UPS is a reliable and efficient solution for maintaining your internet connection during power interruptions. Highly recommended!

Just purchased and working perfectly as expected. The documentation provided is very easy to understand and helps to install. Installation is super easy. Mainly i wanted it for a 9v router and this great device has dual voltage support which is a cherry on the cake. Getting stable wifi throughout and very portable to fix. Update after couple of months : the device still works perfectly and as expected. Made my life so bettter. Best buy of 2025.

Awesome product compatible with any router that has 9v or 12v... Am using in airtel router....

Good consistent backup. It kept my router active for around 4 hrs during a major power cut. Behaves like a real UPS i.e. switchover from a/c to battery is instantaneous. I have used ones which turns off after powercut and then start the Battery supply to router, basically giving it a restart. Crust UPS is a champion in terms of switchover timing ! With frequent power cuts I could easily see the difference with this UPS. Compatibility - both 9V/12V, 1-2Amp routers are supported. Currently using with a 9V powered TP link router. Best part is, there is no manual configuration required. This smart UPS automatically sets the voltage levels and indicates them as well - green for12V and red for 9V Extremely easy to setup. Amber light - for on battery and green light indicator while charging. Very light weight with replaceble battery for future. Sufficient length of output cable with compatible connectors provided in box. My recommendation, go for it, tried many famous brands of ups routers, this newcomer is surprising consistent and amazing !
