The Artis AR-MINIDC-2 is a mini UPS that keeps a Wi-Fi router, modem or set-top box running during a power cut. According to Artis, it has an 8800mAh battery, a 9V/12V DC output rated at 1A, 1.5A or 2A, a 5V USB port for charging a phone, and up to 8 hours of runtime. For most Indian homes with a single 9V or 12V router that draws 2A or less, it is a sensible way to keep the internet alive through short and medium outages.

The short verdict: it is a good pick if your router uses one 9V or 12V adapter and you want a unit with its own power cable, a battery level indicator and a spare USB port. It is the wrong pick if you need to power two boxes at once (for example a separate fibre ONT and a router), or if your router needs more than 2A.

This article is based on the official Artis product page and the Amazon.in listing, both checked on 17 October 2026. It is not a hands-on review, and we have not tested the unit ourselves. Where a detail comes only from the seller listing, we say so.

Quick verdict

Best for: homes and small offices with one 9V or 12V Wi-Fi router, modem or DTH set-top box that needs up to 2A
Skip if: your router or ONT needs more than 2A, uses a different voltage, or you need two DC outputs at the same time
Key strengths: 8800mAh battery, switchable 9V/12V output, zero-lag switching claim, USB port for a phone, battery level LEDs, BIS certification, own power cord
Key limitations: one DC output, “up to 8 hours” is a best-case figure, the 5V USB port draws from the same battery as your router

One caution about the Amazon.in technical table: it lists an “output voltage” of 240 volts and a model number of “AR-UPS”. Neither matches what the product actually does (it outputs 9V or 12V DC) or the AR-MINIDC-2 name Artis uses, so treat those two fields as listing errors rather than specifications.

What a router UPS actually does

A router UPS sits between the wall socket and your router, charging its battery while mains power is on and feeding the Artis AR-MINIDC-2 when it goes. Artis says the AR-MINIDC-2 switches over with zero lag. That matters because even a split-second gap can make a router reboot, leaving you offline for a minute or more while it reconnects, which is exactly what you want to avoid on a video call or in an online class.

A mini UPS only powers small DC devices; it is not an inverter. If an inverter already runs your router’s socket, a router UPS mainly covers the brief changeover gap.

One limit no home UPS can fix: if your internet provider’s equipment outside your home loses power, the Artis AR-MINIDC-2 stays on but the connection may still drop. Ask your provider or a neighbour how the line behaves in long outages.

Output and compatibility: why 9V/12V and 2A matter

Most home routers in India run on a small adapter rated at 12V, and some older or smaller models use 9V. The AR-MINIDC-2 can deliver either, which is its main advantage over 12V-only units. According to Artis, the output is switchable between 9V and 12V, at 1A, 1.5A or 2A, and the unit is designed for devices up to 24W. The Amazon.in listing adds that it suits routers with 0.5A, 1A, 1.5A or 2A input requirements.

Here is how to check your own router in under a minute:

Turn the router’s adapter over and read the “Output” line. It will say something like 12V 1A or 9V 0.6A.
The voltage must match exactly. A 12V router needs the 12V setting, and a 9V router needs 9V. Never guess.
The current (amps) on the adapter must be 2A or less for this UPS. A router that draws less than 2A is fine, because a device only takes the current it needs.
Check the plug that goes into the router. Most routers use a round DC barrel plug, but sizes vary, so compare it with the output cable that comes in the box.

Artis also warns on the listing to check your device’s power requirement on its original charger and to read the user manual before first use. Since the output is switchable, confirm which setting is active before you connect a 9V device. Sending 12V into a 9V router can damage it.

Battery and real backup time

Artis quotes up to 8 hours on the AR-MINIDC-2 product page. Its own router UPS category page, however, describes an 8800mAh battery as giving 4 to 6 hours of use. The honest reading is that 8 hours is a best case with a low-power router, and your figure depends on how much power your router draws.

Two things decide real backup time. The first is your router’s actual draw, which is usually well below the Artis AR-MINIDC-2’s maximum rating. The second is conversion loss: the UPS steps the low cell voltage up to 9V or 12V, and some energy is lost as heat.

Battery mAh ratings usually refer to the cell voltage, not the 12V output, so 8800mAh does not mean 8800mAh at 12V. Artis does not state the cell voltage, so we cannot give an exact watt-hour figure. For a realistic estimate, measure your router’s draw with a plug-in power meter.

The micro-load detection Artis mentions is a small but useful feature. Some power banks and cheaper UPS units switch themselves off if the connected device draws very little power, assuming nothing is plugged in. Artis says this unit stays on with very low-wattage devices, which helps with small modems and set-top boxes.

The USB port and other features

The 5V USB port lets you top up a phone or tablet during an outage. That is handy, but remember it drains the same battery that keeps your router running. Charging a phone from it will shorten your Wi-Fi backup, so use it sparingly in a long power cut.

The LED battery level indicator is more useful than it sounds: it tells you whether the unit is fully charged before a scheduled power cut and roughly how much is left during one.

According to the Amazon.in listing, the unit charges from its own power cable rather than depending on the Artis AR-MINIDC-2’s charger, and Artis lists a power cord in the box.

Build, size and placement

According to the Amazon.in listing, the AR-MINIDC-2 measures 10.5 x 16 x 3.3 cm and weighs 0.36 kg. That is small enough to sit next to a router on a shelf or be tucked behind a TV unit. The listing gives the charge time as 4 hours.

As with any lithium-ion device, keep it ventilated and away from sunlight or warm set-top boxes. If it ever swells or smells hot, unplug it and contact Artis support.

Who should buy it, and who should skip it

Who should buy the Artis AR-MINIDC-2 — Who the Artis AR-MINIDC-2 suits, summarised from this review.

Buy it if you work or study from home, lose internet in short daily power cuts, and have one 9V or 12V router drawing 2A or less. The Artis AR-MINIDC-2 charging port and battery display are useful extras.

Skip it if your fibre ONT and router are separate boxes that both need power (this unit has one DC output), if your router needs more than 2A or 24W, or if an inverter already powers the Artis AR-MINIDC-2 socket cleanly.

Alternatives worth comparing

Facts below are from each brand’s official page.

Artis AR-MINIDC 3: Artis’ bigger sibling, also with an 8800mAh battery and selectable 9V or 12V output, but rated at up to 3A and 36W. It has a 5V USB port rated at 1.8A and lists BIS, CE, FCC and RoHS certification. Choose it if your router needs more than 2A.
Lapcare Cube IV (LMU-123): a smaller 4000mAh unit with 18650 lithium cells and a regulated 12V, 2A output. Lapcare quotes up to 4 hours of backup. It is 12V only, so it will not suit 9V routers.
Geonix Trot R7: uses dual 2000mAh batteries and has three outputs, rated 12V/2A, 9V/2A and 5V/2A, which can power more than one device. Geonix quotes up to 6 hours of backup on its website.

What to check before you order

Artis AR-MINIDC-2 buying checklist — What to check before you buy the Artis AR-MINIDC-2.

Confirm the listing title says AR-MINIDC-2 with an 8800mAh battery, 9V/12V output and black colour. That is the exact variant our link points to. Artis also sells the AR-MINIDC and AR-MINIDC 3, which are different products.
Read your router’s adapter label and make sure it is 9V or 12V and 2A or less.
When it arrives, check the box for the UPS, power cord, output cable, bridge connector and user manual, as listed by Artis.
Register the product on the Artis warranty portal to activate the 1-year warranty, and keep your invoice.
For help, the listing and Artis page give the customer care number 1800 123 8195 and the email inquiry@artis.in.
Charge it fully before you rely on it in an outage.

Frequently asked questions

Will the Artis AR-MINIDC-2 work with a Jio Fiber or Airtel router?

It can, if the router’s adapter says 9V or 12V and 2A or less. The listing names router brands such as TP-Link, D-Link, Netgear, Cisco, Asus, Tenda and Linksys, but brand matters less than the adapter rating. If your fibre setup uses a separate ONT box and a router, you will need two outputs, and this unit has one.

How long will the backup last?

Artis says up to 8 hours on the product page, while its router UPS category page mentions 4 to 6 hours for an 8800mAh battery. Real backup depends on your router’s power draw and on whether you also charge a phone from the USB port.

Does it switch without restarting the router?

Artis claims zero-lag switching, meaning the router should not reboot when the power goes. We have not tested this ourselves.

What warranty does it have?

Artis lists a 1-year warranty with registration through its warranty portal.

Final word

The Artis AR-MINIDC-2 covers the needs of most single-router homes: 9V or 12V output, up to 2A, a large 8800mAh battery, a USB port and a clear battery indicator, backed by BIS certification and a 1-year warranty. Treat the 8-hour claim as a best case, check your adapter label before you buy, and step up to a higher-rated or multi-output unit if your setup needs it.
