Internet dropping during a power cut is one of the most irritating things, especially if you are on a work call or your child is in an online class. A mini UPS for your WiFi router keeps your connection alive even when the light goes, which is very common in many Indian cities and small towns. Instead of using a bulky computer UPS, these small units sit next to your router and quietly keep the internet running.
When you pick a mini router UPS, you need to check voltage and ampere compatibility, backup time, safety features, and how easy it is to install. For Indian homes, you also need to think about long power cuts in summer, frequent voltage fluctuation, and after-sales support. In this guide, I will walk you through 5 good mini UPS options for WiFi routers that suit Indian usage and budgets, and then a practical buying guide so you know what to look for before ordering online.

For a typical home router, you get up to around 3 hours of backup, which is enough for evening outages or short interruptions in many Indian apartments.
The setup is straightforward. You remove your router’s power adapter from the socket, plug that into the Oakter Mini UPS, then connect the UPS output to your router. Since it uses an online UPS style design, there is no delay or drop when power goes off. This helps if you are on video calls or gaming, where even a short disconnect can kick you out. The battery charges automatically when mains power is available, so you do not need to think about it on a daily basis.
Oakter has added protections for overcurrent, short circuit, overcharging, deep discharging, and high voltage. This matters in many Indian homes where voltage fluctuation can damage small electronics over time. The brand is Indian and has built a decent presence in smart home accessories, with service handled through local channels and marketplaces. Response quality will depend on your city, but being a local brand helps with repair or replacement compared to no-name imports. For someone who wants a compact, no-nonsense router UPS mainly for 1 to 3 hour power cuts, Oakter Mini UPS Basic is a sensible option.
Portronics Power Plus II Mini UPS
12V mini UPS from Portronics with up to 4 hours backup and automatic switching for home and office routers.
Pros
- Supports 12V routers with up to 3A current draw
- Automatic switchover to battery during power cut
- Plug-and-play install with no tools
- Compact body from a known Indian accessories brand
Cons
- Only 12V output, no 9V option

Backup time depends on your router’s consumption, but Portronics claims up to about 4 hours in regular use. For cities with 1 to 2 hour outages, this gives a bit of headroom so you are not stressed if the cut extends.
Installation is simple. You place the mini UPS between the wall socket and the router, using the provided cables. Once connected, the device automatically switches to battery mode when electricity goes and returns to mains when supply is restored. You do not need to press any button or change any setting. This also prevents VPN or streaming sessions from dropping when the power flickers, which is useful for WFH professionals and students in Indian households.
Portronics is a popular Indian accessories brand with wide service coverage through service centers and courier pickup in many cities. Their warranty process is generally straightforward, which is important for a product that may run 24×7. For people in tier 2 or tier 3 towns, Portronics products are also easy to source from online platforms with proper GST billing and support. If you want a router UPS that handles higher power routers comfortably and comes from a familiar brand name, Power Plus II is worth considering.
Cuzor Mini UPS 12V 2A
Made-in-India 12V mini UPS with replaceable battery and up to 5 hours backup for routers up to 2A.
Pros
- Up to 5 hours backup with dual 2900 mAh cells
- Replaceable battery design for longer product life
- Supports most 12V routers up to 2A
- Zero lag switching during power cuts
Cons
- No 9V support, only 12V output
- Relies on a 12V 1.5A or higher adapter for best performance
- Not compatible with PoE AirFiber setups
- Brand presence smaller outside major cities
Cuzor Mini UPS 12V 2A is built by a Bengaluru based company focused on router backup products. It uses two 2900 mAh EV grade cells and offers up to around 5 hours of backup for typical routers, which is higher than many compact units in this segment. Power rating covers 12V 0.5A, 1A, 1.5A and 2A routers, so most standard broadband setups in Indian homes will fit without problem. Cuzor clearly states that it supports wired broadband and optical fiber routers, but not PoE AirFiber connections that power an outdoor antenna.
One standout feature is the replaceable battery. Many mini UPS devices work well initially but lose capacity after a few years, and you end up buying a full new unit. With Cuzor, you can open the case and replace the battery module, so the electronics and casing continue to serve you. This makes sense for value conscious users, and also reduces e-waste. The company suggests using a 12V 1.5A or higher adapter for best performance, which most modern routers already include.
The unit supports plug and play installation with zero lag switching. That means your Zoom, Meet, or gaming sessions do not drop when the light goes. Safety protections cover short circuit, overcharging, deep discharge, and high voltage. Since Cuzor is a smaller but focused Indian brand, support is usually handled quickly through online channels, though physical service centers are limited compared to older consumer electronics players. For users who face 2 to 4 hour power cuts regularly and want longer backup with a repair friendly design, Cuzor Mini UPS is a strong choice.
Resonate RouterUPS Gen2 12V
High capacity 12V router UPS with 7800 mAh battery and up to 6 hours backup from one of the first router UPS brands in India.
Pros
- Up to 6 hours internet backup in ideal conditions
- Intelligent charging with BIS, CE and RoHS certifications
- Supports most 12V routers up to 2A
- Battery replacement program offered by the brand
Cons
- Only 12V up to 2A, high power 3A routers need another variant
- Not suitable for Jio or Airtel Air Fiber, and some ISP specific routers
- Bulkier than the smallest mini UPS units
- Higher cost than basic low capacity options
Resonate RouterUPS Gen2 is among the more mature options in the Indian market. The company pioneered the dedicated router UPS segment and this Gen2 model improves capacity and safety. It uses three 2600 mAh lithium ion cells for a total of 7800 mAh, which translates to up to 6 hours of backup for typical home routers. For many Indian users, this means the router keeps running through even extended load shedding or unplanned outages during heavy rain.
The device is compatible with 12V routers up to 2A, modems, and other small devices in that power range. For very high power routers from brands like NetLink, Syrotech or Alphion, Resonate directs users to a different 12V 3A variant. It is also not meant for Jio Air Fiber, Airtel Air Fiber, and some BSNL or Kerala Vision gear that uses PoE or special power setups. Before buying, you need to check the voltage and ampere rating printed on your router’s adapter, which is a habit you should build anyway for any mini UPS purchase.
Resonate focuses heavily on safety. The RouterUPS Gen2 comes with BIS, CE and RoHS certifications and 6 layer protection that controls overcharging, overheating and short circuits. The charging logic is tuned to improve battery life, which matters in hot Indian summers where electronics tend to heat up and age faster. Resonate also runs a battery replacement program, starting at a transparent price, so you can keep the same unit running for many years without full replacement. Support is available over phone and WhatsApp, and the brand has a good reputation in online communities for responsive help. For someone who wants long backup and proven design from a specialist brand, this model makes sense even if you pay more than basic units.
Artis AR-MINIDC-2 Mini UPS
High capacity 8800 mAh mini UPS with 9V and 12V support plus USB output, suited for mixed home setups.
Pros
- Supports both 9V and 12V routers up to 2A
- Large 8800 mAh battery with up to 8 hours backup
- Built in USB port for smartphone charging
- Battery level indicators for quick status check
Cons
- Slightly larger and heavier than ultra compact units
- Needs correct voltage selection and compatibility check
- Brand support quality can vary by city
- Extra features may be overkill for short outage areas
Artis AR-MINIDC-2 Mini UPS is aimed at homes and small offices that run a mix of devices and want one backup unit to handle them. The big plus is support for both 9V and 12V outputs, with current ratings of 1A, 1.5A and 2A. Many older routers and some DTH set top boxes use 9V adapters, while newer dual band routers use 12V. This UPS covers both, so you have more flexibility if you change your router in the future. Artis claims up to 8 hours backup from the 8800 mAh battery under light load, which is useful in areas with long daily cuts.
The unit is not only for routers. You can connect a DTH set top box or modem, and there is also a USB port that supports smartphone charging. During a long outage, this acts like a small power bank for your phone so you stay reachable, while your router and TV set top box keep working. Battery level indicators on the front give a simple visual idea of remaining charge, which many users in Indian families find more intuitive than checking an app or guessing.
Artis is an Indian brand with experience in audio and power products, and its mini UPS range is BIS certified. They provide a direct power cable for the UPS, so you are not dependent on the router’s adapter for charging the unit. That helps where router adapters are under rated or old. Service support is available through a toll free number and email, with centers in major cities and courier support elsewhere. If you want one mini UPS that supports multiple voltages, offers long backup, and can double as an emergency phone charger during long summer and monsoon outages, AR-MINIDC-2 offers strong value for Indian homes.
Buying Guide
Check your router’s voltage and ampere rating
Before you even look at mini UPS models, pick up your router’s original adapter and read the label. You will see something like “Output: 12V 1A” or “Output: 9V 0.5A”. Your mini UPS must match the voltage exactly and support equal or higher ampere (A) than what is printed. For example, if your adapter says 12V 1A, you can pick a UPS rated for 12V 1A, 1.5A or 2A. Never use a 9V UPS for a 12V router or vice versa. Getting this wrong can damage both the router and the UPS and will void warranty.
Decide how many hours of backup you need
Think about your local power cut pattern. In many metros, cuts last 30 minutes to 1 hour. In small towns and some rural areas, they can stretch to 3 to 6 hours, especially during summer or heavy rains. If cuts are short, a 2 to 3 hour backup unit is enough and cheaper. If cuts often cross 2 hours, pick a higher capacity model that offers around 5 to 8 hours under typical router loads. Keep in mind that faster dual band routers draw more power, so your real backup time will be lower than the marketing number. If you work from home full time, factor in a safety margin rather than stretching a small battery to the limit every day.
Think about other devices you want to back up
Many people only think about the router, but your broadband modem or ONU may also need power. Fiber connections often use a separate ONT box powered at 12V. Some mini UPS models can feed both the router and the ONT if power ratings match. Others are better kept separate. You might also want to keep a DTH set top box or a small CCTV camera alive during a cut. If you own such devices, look for a UPS with multiple output options or at least flexible voltage support, like 9V and 12V. A unit with a USB output is useful to charge phones during long outages when you do not want to drain your main power bank.
Safety features for Indian power conditions
Indian power grids often see voltage spikes, surges when power returns, and low voltage brownouts. A good router UPS needs protections for overcurrent, short circuit, overcharging, deep discharge, and high voltage. Deep discharge protection helps the battery last longer by preventing it from being drained to zero daily. Intelligent charging or smart battery management helps reduce heat build up, especially in hot cities where summer room temperatures stay high. Certified products with BIS and recognized safety marks give some assurance that the device has passed basic safety testing.
Build quality, form factor and installation
You will usually keep the mini UPS near your router, often on a crowded shelf. A compact and light design is easier to manage in small Indian flats. Look at wire quality, connector fit, and whether the case feels sturdy enough for daily use. Some models support wall mounting, which helps free up space and keeps cables tidy, especially in homes with kids. Plug and play installation is important since most users do not want to open wiring or use tools. Ideally, you should be able to set up the UPS in under 5 minutes by connecting the input and output cables as instructed in the manual.
Warranty, service network and support
Since a mini UPS runs 24×7 next to your router, reliability matters. Always check the warranty period and what type of service is offered. A one year replacement warranty where the company arranges pickup and drop is convenient, especially if you live in a tier 2 or tier 3 city. Brands with clear WhatsApp or phone support lines are easier to reach when something goes wrong. India based companies that specialize in such products often respond faster because they understand local power issues well. Also, look for options where batteries can be replaced or where the brand offers a structured battery replacement program, so you do not throw away the full unit after a couple of years.
Budget planning and value for money
Mini router UPS products sit in a wide price band. Basic models offer 2 to 3 hours backup with fewer features. Mid tier units add more backup time and safety protections. High capacity models offer long backup, multiple voltages, and extra outputs like USB charging. Rather than picking the cheapest, match the product to your use. If you live in an area with rare, short cuts, a simple unit is fine. If you depend on the internet for work or run a small business with online billing, investing a bit more in a reliable brand with good safety features and long backup pays off. Remember, a few hundred rupees saved upfront can feel small compared to the cost of missed meetings, online exams, or damaged routers.
Practical usage tips for Indian homes
Place the mini UPS in a well ventilated spot near the router, away from direct sunlight or closed cabinets where heat builds up. In summer, rooms can get hot, which shortens battery life, so basic airflow helps. Ensure that cables are not dangling where someone might trip. Once a month, allow the UPS to discharge partially during a power cut or by switching off mains for a short time, then let it charge back. This gentle cycle helps lithium batteries stay healthy. Keep the user manual and warranty details safe, and note the purchase date. If you change your router model, always recheck voltage and ampere needs before reconnecting the UPS.
