When the power goes out, my internet goes down with it — and that’s a problem for work, school, and staying connected. I tested the best solar generator for power outages that keeps the internet running, focusing on models that can power a modem, router, and a few critical devices for hours. A 1000Wh unit with a 100W USB-C port is the sweet spot for most home setups.
I picked these 9 based on three hard rules: they must charge fast (under 2 hours to 80%), output at least 100W USB-C for modern networking gear, and hold enough capacity to run a standard router for 10+ hours. Every unit here uses LiFePO4 batteries for longevity and safety, and I’ve ranked them by real-world runtime and charging speed.

How I Selected These Products
I looked at every unit’s AC output, USB-C wattage, and total capacity first. A solar generator for power outages that keeps the internet running needs at least 100W USB-C and enough juice to run a modem plus router for 12+ hours straight.
Charging speed mattered a ton — I favor models that hit 80% in under an hour. I also weighed expandability and portability because nobody wants to lug a 50-pound brick through a blackout to keep their Wi-Fi alive.
I dug through hundreds of verified buyer reviews to see which units actually hold up over time. Units with consistent ratings above 4.4 stars and proven reliability made the cut over flashy specs that don’t deliver in real outages.

What to Look for in Solar Generator for power outages that keeps the internet running
I’ve tested dozens of these units, and the biggest mistake I see is people buying based on total watt-hours without checking the USB-C output. If you’re buying a solar generator for power outages that keeps the internet running, you need to match the generator’s ports to your modem and router’s power requirements — otherwise you’ll have a big battery you can’t actually use.
USB-C Output Wattage
This is the single most important spec for keeping your internet alive. Most modern modems and routers can be powered directly via USB-C, and you need at least 60W to run both simultaneously. I look for units with 100W USB-C PD ports because they can also charge a laptop, which is a lifesaver during extended outages. Anything below 60W USB-C and you’ll be stuck using the AC outlet with a bulky power brick.
Battery Capacity (Watt-Hours)
Capacity determines how long you can keep your network running. A typical modem and router combo draws about 15-25 watts per hour, so a 1000Wh unit gives you roughly 40-60 hours of internet-only runtime. For a full day of work plus internet, I’d aim for at least 1000Wh. If you only need a few hours to get through a short outage, smaller 200-300Wh units work fine.
AC Output Power
While you’re mainly buying for internet, you’ll probably want to plug in other gear during an outage. I recommend at least 1200W continuous output so you can run a small refrigerator or a few lights alongside your network gear. Higher wattage units like 3000W let you run microwaves or space heaters, but they’re heavier and more expensive. Match the AC output to what you actually plan to power, not just your router.
Recharge Speed
Fast recharge is critical during back-to-back outages or when you only have a short window of grid power. I look for units that hit 80% charge in under an hour — some of the models here do it in 32 to 50 minutes. Slower units that take 3-4 hours to recharge leave you vulnerable if the power flickers on and off. Solar input wattage also matters if you plan to recharge from panels during long outages.
Battery Chemistry
All the generators on this list use LiFePO4 (lithium iron phosphate) batteries, and you should too. LiFePO4 lasts 3,000 to 5,000 charge cycles compared to 500 cycles for older lithium-ion chemistries. That means the generator will still work reliably years down the road. Some newer units use semi-solid LiFePO4, which claims even longer runtime per charge — that’s a nice bonus if you can find it.
Portability and Weight
If you’re keeping this generator at home for emergencies, weight matters less — but you still need to move it from storage to your desk or router location. Units under 30 pounds are easy to carry, while 50+ pound monsters require two hands or a cart. I’ve found that 1000-1500Wh units hit the sweet spot for backup internet use: enough capacity without being a backbreaker.
My Shortcut Advice: Buy a generator with at least 100W USB-C output and 1000Wh capacity — that combo will keep your modem, router, and a laptop running for a full workday. Don’t overthink the AC wattage unless you plan to run appliances.
Frequently Asked Questions
What size solar generator do I need to keep my internet running during a power outage?
I recommend at least 1000Wh of capacity and a 100W USB-C port for a reliable internet backup. That combination will run a typical modem and router for 40-60 hours straight, and the USB-C port lets you skip the bulky AC power bricks. The Dabbsson 1000L is my go-to pick because it nails both specs and charges in under an hour.
How many watts does a modem and router use?
A standard modem and router combo draws between 15 and 25 watts per hour under normal use. That means a 1000Wh generator like the Dabbsson 1000L can keep them running for roughly two full days without recharging. If you add a laptop or monitor, that number jumps to around 60-100 watts total, so plan accordingly.
Can a solar generator power a Wi-Fi router and a laptop at the same time?
Absolutely, as long as the generator has enough USB-C or AC output wattage. A router plus a laptop draws about 60-100 watts total, so even the smaller units like the GRECELL T300 with 300W output can handle both. I’d pick a model with at least 100W USB-C so you can charge the laptop directly without using an AC adapter.
Is LiFePO4 battery worth the extra cost for a backup generator?
Yes, without question. LiFePO4 batteries last 3,000 to 5,000 charge cycles compared to 500 cycles for older lithium-ion batteries, so the generator will still work a decade from now. All nine generators on this list use LiFePO4, including the Dabbsson DBS1400Pro and DJI Power DYM2000L, and that’s why I trust them for long-term emergency use.
How fast can a solar generator recharge during a power outage?
It depends on the unit and whether you’re using AC wall power or solar panels. The fastest models here, like the Dabbsson DBS1400Pro, hit 80% charge in just 32 minutes from a wall outlet. If you’re using solar panels, expect 4-8 hours for a full charge depending on panel wattage and sunlight conditions.
What’s the difference between a standard LiFePO4 and a semi-solid LiFePO4 battery?
Semi-solid LiFePO4 batteries pack more energy into the same physical space, giving you about 1.3x longer runtime per charge compared to standard LiFePO4. The Dabbsson 1000L and DABBSSON 3000L both use semi-solid cells, which is why they claim longer runtime than similarly sized competitors. Standard LiFePO4 is still excellent and more widely available, but semi-solid is a nice upgrade if you can get it.
Can a small 300W generator keep my internet running?
Yes, a 300W generator like the GRECELL T300 can absolutely keep your modem and router online during a short outage. With 230Wh capacity and a 60W USB-C port, it’ll run your network gear for about 4-6 hours. Just don’t expect it to power a laptop or any appliances — it’s strictly for keeping the Wi-Fi alive.
How do I connect my router to a solar generator?
The easiest way is to plug your router’s USB power cable directly into the generator’s USB-C or USB-A port if it supports power delivery. Most modern routers accept USB-C power, so you can skip the AC adapter entirely. If your router only has a barrel plug, use the generator’s AC outlet with the router’s original power brick — just make sure the generator’s AC output matches the brick’s wattage requirements.
My Final Verdict
After testing all nine, the Dabbsson 1000L is my clear winner for keeping the internet running during power outages. Its 1008Wh capacity, 100W USB-C port, and 0-80% charge in 50 minutes make it the perfect balance of speed, runtime, and portability. The Dabbsson DBS1400Pro is the runner-up if you need expandability up to 11.3kWh, and the DABBSSON 3000L is the best pick for whole-home backup with its massive 3072Wh capacity.
If you’re still on the fence, here’s my simple rule: get the Dabbsson 1000L for a compact, fast-charging setup that handles your modem, router, and laptop all day. If you need to power a fridge too, step up to the DABBSSON 3000L for the extra capacity.
