Review: Works great with the Virgin Media Super Hub - I’ve experienced a few power cuts (and hating the long sync times that occur after a power outage) recently and while I already have a big UPS for my main PC and monitor, I don’t have anything to protect my router because it’s in a different room. When I opened the packaging I examined the mini UPS unit and I was surprised at how small it was. It seemed to be made from good hard ABS plastic and had a nice weight to it. Also included in the box was 3 x barrel jack adapters, a barrel lead and a 12v UK power supply. On top of the unit it had 2 LEDs (1 green & 1 red) to signify battery status, with the red LED only lighting when the internal 18650 batteries were charging and the green LED indicating that unit had AC power. There was also a button on top which was just an on/off switch. On the back of the unit it had various connectors, these were: a 5v USB port supplying 1 amp, a 12v barrel connector (for output voltage) and a 12v power input port for connecting the included power supply. I connected the device up to my Virgin Super Hub and it seemed to be already charged up but operation wise the Virgin router seemed fine with no speed or stability issues. This mini UPS has functioned great since I’ve had and although there’s no audible warning when the power is cut it has just done its job effortlessly (what more could you ask for). I can thoroughly recommended this for those people with a VM Super Hub 2ac (and SH 3 as it’s the same PSU) - it’s easy to setup and doesn’t require much attention once functioning, top marks. I’ve included various pictures. Thanks for taking the time to read my review. Review: Good piece of kit but beware if you want it for a BT Homehub. - This works exactly as it should and runs a router for a time if the power goes off. It is good value for what it does. I have not yet tested it to see just how long it will run the router but it definitely works for relatively short interruptions. However, I can confirm the comment in another review that neither the supplied connector nor the adaptors will fit a BT Homehub. In quite extensive research, I failed to find a ready made alternative connector that would fit. After a lot more research, and measuring of the plug needed, I finally found a supplier of the correct plug and so was able to replace the plug on one end of the supplied connector. It all now works perfectly and I am pleased with the unit but if you are not handy with a soldering iron and want this for a BT Homehub, you may have problems. ## Technical Specifications | Specification | Value | |---------------|-------| | ASIN | B075QZQSS1 | | Amperage | 2 Amps | | Battery Cell Type | Lithium Ion | | Battery Charge Time | 8 Hours | | Brand Name | iNepo | | Colour | GM312 UPS | | Connector Type | USB | | Customer Reviews | 3.8 3.8 out of 5 stars (61) | | Form Factor | Compact | | Input Voltage | 12 Volts | | Manufacturer | ruihongfushi | | Manufacturer Part Number | UPS | | Model Number | GM312 | | Number of Outlets | 2 | | Output Current | 1 Amps, 2 Amps | | Output Voltage | 12 Volts | | Output Wattage | 24 Watts | | Power Plug Type | Type G | | Runtime | 1 hour and 5 minutes | | Voltage | 5 Volts | | Wattage | 24 watts | ## Product Details - **Amperage:** 2 Amps - **Battery cell composition:** Lithium Ion - **Brand:** iNepo - **Colour:** GM312 UPS - **Voltage:** 5 Volts ## Images ![Mini UPS Uninterrupted Power Supply 7800mah 12V 2A USB 5V 1A Output Power Bank (GM312 UPS) - Image 1](https://m.media-amazon.com/images/I/51MkzfQJ00S.jpg) ![Mini UPS Uninterrupted Power Supply 7800mah 12V 2A USB 5V 1A Output Power Bank (GM312 UPS) - Image 2](https://m.media-amazon.com/images/I/61qJfmEO2kL.jpg) ![Mini UPS Uninterrupted Power Supply 7800mah 12V 2A USB 5V 1A Output Power Bank (GM312 UPS) - Image 3](https://m.media-amazon.com/images/I/71UcBN6HrAL.jpg) ![Mini UPS Uninterrupted Power Supply 7800mah 12V 2A USB 5V 1A Output Power Bank (GM312 UPS) - Image 4](https://m.media-amazon.com/images/I/61TmymJaXML.jpg) ![Mini UPS Uninterrupted Power Supply 7800mah 12V 2A USB 5V 1A Output Power Bank (GM312 UPS) - Image 5](https://m.media-amazon.com/images/I/61hUPLkgejL.jpg) ## Questions & Answers **Q: Does this work with the bt smart hub?** A: NOT AS-IT-COMES. The 12 VDC voltage is fine for the BT Smart Hub 5, but the barrel plugs will NOT fit with the cable and adapter provided. The fault lies with BT, who have chosen a very rare plug for the BT Smart Hub 5. I tried to measure the plug and to me it appeared to be 5.5mm outside diameter, 3.0mm inside diameter. HOWEVER, I have seen another reviewer (I L) who shopped around online to find the right plug, and he said it would be 6.3mm outside diameter, 3.1mm inside diameter. If you're can find the right plug, and are handy with soldering, it can be done, but getting it all right requires determination. **Q: After reading a review by i l it looks like this ups won’t work with the latest bt homehub, what size barrel connector is required?** A: You need a 3.1mm x 6.3mm Male DC Power Plug Connector Jack - I paid £1.69, including p&p, for one on-line. It fits the latest BT (Smart) home hub and it is easy to replace one end of the connector supplied with the new one. Having done so this UPS works well with the BT home hub - having had a few power-cuts since installing it and no break in my internet connection. **Q: Does it sound an alarm when running on battery - and if so, can the alarm be switched off?** A: There's no alarm. You can tell by the LEDs if it's charging but there's nothing audible. **Q: Has this got the right adaptor to be used with a Virgin Media box/hub ?** A: I don't know but it comes with 4 different round pin adapters ## Customer Reviews ### ⭐⭐⭐⭐⭐ Works great with the Virgin Media Super Hub *by M***S on 28 May 2018* I’ve experienced a few power cuts (and hating the long sync times that occur after a power outage) recently and while I already have a big UPS for my main PC and monitor, I don’t have anything to protect my router because it’s in a different room.

Didn't work for my Virgin Hub 3, switch or other wi-fi. *by P***M on 1 April 2020* This was a promising proposition - get a few hours of broadband wifi even with the mains power off. Unfortunately the 2A output at 12V seems aspirational. I checked with a meter and here's 12V across the terminals, but I couldn't even power up a 12V/1A rated network switch with it, let alone the 12V/2A Virgin hub 3 or anything else. It does charge a mobile phone OK, but it's expensive for a power bank, if that's all it really can do. UPDATE: I managed to find a 12V device it would power up. A decorative light rated at 0.5A. Not much benefit to UPS functionality there though unfortunately! --- ## Why Shop on Desertcart? - 🛒 **Trusted by 1.3+ Million Shoppers** — Serving international shoppers since 2016 - 🌍 **Shop Globally** — Access 737+ million products across 21 categories - 💰 **No Hidden Fees** — All customs, duties, and taxes included in the price - 🔄 **15-Day Free Returns** — Hassle-free returns (30 days for PRO members) - 🔒 **Secure Payments** — Trusted payment options with buyer protection - ⭐ **TrustPilot Rated 4.5/5** — Based on 8,000+ happy customer reviews **Shop now:** [https://www.desertcart.tn/products/50359160-mini-ups-uninterrupted-power-supply-7800mah-12v-2a-usb-5v](https://www.desertcart.tn/products/50359160-mini-ups-uninterrupted-power-supply-7800mah-12v-2a-usb-5v) --- *Product available on Desertcart Tunisia* *Store origin: TN* *Last updated: 2026-06-01*
