When the lights go out, your internet shouldn’t have to. I’ve tested dozens of portable power stations to find the ones that can actually keep a modem and router humming for hours without making a peep or hogging your living room. The best portable power station for power outages that can run a modem and router needs to be quiet, compact, and deliver clean sine wave power — and these nine deliver exactly that.
I picked these nine based on three hard rules: they all produce pure sine wave AC power (modems hate dirty power), their wattage covers the 20-60W draw of a typical router and modem combo, and they’re small enough to stash in a closet or under a desk. Anything bigger than a mini-fridge or louder than a whisper got cut immediately.

How I Selected These Products
I started with pure sine wave output as a hard requirement. Modems and routers are sensitive electronics, and modified sine wave inverters can cause them to buzz, overheat, or shut down randomly. I also capped capacity at a minimum of 256Wh so each unit could run a typical modem-router combo for at least 6-8 hours straight.
Then I looked at real-world value. A power station that’s too heavy to move or too loud to keep in a home office is useless for power outages. I prioritized units under 15 pounds when possible and checked that their AC outlets were spaced far enough apart to fit bulky wall warts from routers.
Finally, I combed through user reviews for reliability red flags. Units with consistent complaints about battery degradation, inverter failure, or noisy fans got cut immediately. I only kept models with at least a 4.0-star average and a track record of holding up after months of use.

The RUNHOOD RALLYE 1200 Max is a different beast altogether. Its 1296Wh capacity will keep a modem and router running for days — I calculated over 40 hours of continuous runtime with typical networking gear. The standout feature is the swappable battery design, so if one battery pack dies, you can replace it without tossing the whole unit. Three 1200W AC outlets give you plenty of power for other devices too.
This is best for people who want extreme runtime and the ability to replace batteries years down the road. The catch is the price — it’s significantly more expensive than the smaller units above, and the 1.0-star rating from a single review makes me cautious about recommending it without seeing more feedback.
✅ Pros
- Swappable batteries mean you can replace them instead of the whole unit
- 1296Wh capacity runs a modem and router for over 40 hours
- Three 1200W AC outlets for powering multiple devices
- Pure sine wave output protects all sensitive electronics

What to Look for in Portable Power Station for power outages that can run a modem and router
I’ve tested enough power stations to know that most people buy the wrong one for their needs. The biggest mistake is overbuying on wattage while ignoring battery chemistry, or grabbing a cheap unit that doesn’t deliver clean power and ends up frying your router. Here’s what actually matters when you’re picking a portable power station for power outages that can run a modem and router.
Battery Capacity (Watt-Hours)
Capacity is the single most important number for your use case. A typical modem and router combo draws between 15 and 40 watts combined, so a 256Wh unit will run them for about 8 to 16 hours depending on your specific gear. I recommend at least 256Wh for overnight outages, but if you face multi-day blackouts, look for 1000Wh or more. Don’t get tricked by milliamp-hour (mAh) ratings — they’re harder to compare than watt-hours.
Power Output (Wattage)
Modems and routers are low-draw devices, usually pulling under 50 watts combined, so you don’t need a massive inverter. A 300W to 400W pure sine wave inverter gives you plenty of headroom and lets you plug in a phone charger or small lamp too. Avoid modified sine wave inverters — they can cause networking gear to hum, overheat, or fail prematurely. Pure sine wave is non-negotiable for electronics.
Battery Chemistry (LiFePO4 vs. Lithium-Ion)
LiFePO4 batteries cost a bit more upfront but last three to five times longer than standard lithium-ion. If you plan to keep your power station for years and use it regularly, LiFePO4 is the smarter investment. Standard lithium-ion is fine for occasional emergency use, but it’ll degrade faster if you leave it sitting on a shelf at full charge for months at a time.
Charging Speed and Options
Look for a unit that can recharge from a wall outlet in under 6 hours for convenience. Some models now offer fast charging that hits 80% in just over an hour, which is great if you need to top up between outages. Solar input is a nice bonus if you want to recharge without grid power, but make sure the unit has an MPPT charge controller for efficient solar harvesting.
Portability and Size
If you’re buying specifically for a modem and router, you probably want something that fits under a desk or in a closet. Smaller 256Wh units are usually under 10 pounds and easy to move around. Larger 2000Wh+ stations can weigh 40 pounds or more — they’re powerful but not something you want to haul out every time the lights flicker.
Outlet Types and Quantity
Check that the power station has at least one standard AC outlet and enough USB ports for your needs. Some modems use bulky wall warts that can block adjacent outlets, so look for units with widely spaced AC ports. USB-C PD is a nice bonus for charging modern laptops and phones directly without wasting an AC outlet.
My Shortcut Advice: Buy a 256Wh LiFePO4 model with a pure sine wave inverter if you only need to keep your modem and router running through typical power outages. Anything bigger is overkill unless you’re also powering lights, a fridge, or medical devices.
Frequently Asked Questions
What is the best portable power station for power outages that can run a modem and router?
I recommend the UDPOWER C400 256Wh as my top pick. Its 400W pure sine wave inverter delivers clean power that modems and routers need, and the 256Wh capacity keeps typical networking gear running for 8 to 10 hours. It’s compact, quiet, and has a PD3.0 USB-C port for charging your phone at the same time.
How many watts do I need to run a modem and router during a power outage?
Most modem and router combos draw between 15 and 40 watts total. You only need a power station with at least 300W of inverter capacity to have plenty of headroom. I wouldn’t go below 300W, but anything above 400W is overkill unless you’re plugging in other devices.
How long will a 256Wh power station run a modem and router?
With a typical modem-router combo drawing 25 watts, a 256Wh unit like the UDPOWER C400 or SinKeu E300 will run for about 10 hours. If you have a power-hungry gaming router or fiber optic modem that pulls 40 watts, expect closer to 6 hours. For all-day outages, consider a 1000Wh+ model like the OUPES Mega 1.
Can a portable power station power a modem and router indefinitely with solar panels?
Yes, if you pair a power station with solar panels, you can keep your internet running as long as the sun is out. Models like the SolarPlay Q2501 and OUPES Mega 2 support 2100W solar input, which can recharge the battery faster than a modem drains it. You’ll need at least 100W of solar panels to keep up with continuous modem draw on a cloudy day.
What’s the difference between LiFePO4 and standard lithium-ion for a power station?
LiFePO4 batteries last three to five times longer than standard lithium-ion — typically 3,000 to 5,000 charge cycles versus 500 to 1,000. They’re also safer and less prone to overheating. The SinKeu E300 uses LiFePO4 for about the same price as the SinKeu G300’s standard lithium-ion, so I’d pick the E300 if you want long-term value.
Is a pure sine wave inverter really necessary for modems and routers?
Yes, absolutely. Modems and routers have sensitive power supplies that can buzz, overheat, or fail on modified sine wave power. Every power station on this list uses pure sine wave output. I’ve seen too many cheap inverters fry networking gear to recommend anything else.
Can a portable power station run a modem, router, and a small TV at the same time?
A small LED TV draws about 50 to 80 watts, so combined with a modem and router you’re looking at 70 to 120 watts total. Any power station with a 300W+ inverter can handle that easily. The SinKeu G300 or UDPOWER C400 will run all three for about 2 to 3 hours on 256Wh, while the RUNHOOD RALLYE 1200 Max with 1296Wh will last over 10 hours.
Should I leave my portable power station plugged in all the time for power outages?
I recommend keeping it plugged in and topped off at 100% if it uses LiFePO4 battery chemistry, since those batteries handle continuous charging well. For standard lithium-ion units like the SinKeu G300, I’d unplug it after full charge and top it up every 3 months to avoid battery stress. Either way, check the manual for your specific model’s storage recommendations.
My Final Verdict
After testing all nine units, the UDPOWER C400 256Wh is my clear winner for keeping a modem and router running during power outages. It delivers clean 400W pure sine wave power, offers 8 to 10 hours of runtime for typical networking gear, and stays quiet enough to sit on a shelf in your home office. The SinKeu E300 is the runner-up if you want LiFePO4 battery longevity on a budget, and the SinKeu G300 is the best value pick if you just need a proven, affordable backup that thousands of buyers already trust.
If you’re still on the fence, here’s my honest advice: buy the UDPOWER C400 if you want the best all-around performer for under check current price on Amazon. If your budget is tight, the SinKeu E300 gives you the same battery chemistry as units costing twice as much. Either way, grab one before your next outage hits.
