Mini UPS

A mini UPS is a small uninterruptible power supply. Its job is narrow and practical: when the mains supply fails, it takes over instantly from its internal battery and keeps a small device running, so a router stays online, a modem stays connected, or a camera keeps recording. It is not a large room-sized UPS for servers, and it is not a power bank for charging phones, although the two are sometimes confused. The difference is in the design: a mini UPS is built to sit permanently between the outlet and the device, switching to battery without interruption, while a power bank is built to be charged and carried. The blog post on the difference between a mini UPS and a power bank explains that distinction in full.

Richroc lists mini UPS as one of its two main lines, alongside backup batteries. The company's store profile records it as a Verified Custom Manufacturer, with a total floorspace of 2,630 square metres and full customisation capability, both cited there as findings of an independent third-party verification report. Those verified facts are the basis for the manufacturer claim on this site. No individual mini UPS model on this site carries a published specification sheet, so this page stays at category level: it describes what mini UPS units are for, which devices they serve, and how to choose, without assigning a specification table to a named model.

The devices a mini UPS most often protects are the ones a household or small office notices first when they stop. A WiFi router is the leading case, because every device on the network depends on it, and a router that loses power takes the whole network down even though laptops and phones still hold charge. A modem is the second case, and is often protected together with the router, since the two form one chain to the internet. A CCTV camera is a third case, where the cost of a gap is not inconvenience but a hole in the security record. The application pages for routers, WiFi, modems, CCTV, and home use each work through one of those cases.

Choosing a mini UPS starts with the device it must power, not with the UPS itself. The device label states its voltage and its power draw, and those two figures decide which UPS can serve it. A router that runs on 12V cannot be served by a unit that only outputs 5V, and a camera that draws more current than the UPS can deliver will not run for long even if the voltage matches. The voltage guides on this site explain the common outputs in general terms, and the capacity guides explain how battery size relates to running time. Neither guide assigns a figure to a named model, because no model here has published one.

Outputs matter as much as voltage. Many small devices need more than one voltage at once: a router and modem pair may share one adapter arrangement, or a setup may include a camera and a network switch side by side. Multi-output units address that by offering several outputs from one battery, and the multi-output page explains how to think about them: add up the devices, check each voltage, and confirm the total draw before ordering. A unit with the right voltages but too little total output is no better than a unit with the wrong voltage, and both mistakes are avoidable by checking the labels first.

For buyers sourcing in quantity, the route is the inquiry form. Minimum order quantity is confirmed per order, and customisation, including output combinations and housings, can be discussed as part of an order, because the company profile records full customisation capability. Certificates are available upon request. Delivery time is not published on this site, so it should be raised in the inquiry. The contact page carries the form and the name of the company contact, Ms. Zita Huang, and no telephone number, email address, or street address is published anywhere on this site pending verification.
