Why You Can Never Run a Gas Generator Indoors (And What Actually Works Instead)
Gas generators produce carbon monoxide fast enough to be fatal indoors within minutes. Here's what a solar-rechargeable power station can run safely inside your home during a blackout.

The Carbon Monoxide Risk Most People Underestimate
Every winter, emergency rooms see a predictable spike in carbon monoxide poisoning cases tied directly to gas generators run too close to a home during a power outage. The gas is colorless and odorless, which is exactly why it’s dangerous — by the time symptoms appear (headache, dizziness, confusion), exposure may already be at a critical level. The Consumer Product Safety Commission has been explicit on this point for years: a gas generator must run entirely outdoors, far from any window, door, or vent, regardless of weather. Running one in a garage, even with the door open, is not safe.
What Actually Changes With a Solar Generator
A solar-rechargeable portable power station works on a completely different principle — it stores electricity in a battery rather than burning fuel to generate it on demand. That means zero combustion, zero emissions, and zero carbon monoxide risk, which is what makes it safe to run indoors, including in a bedroom next to a CPAP machine or medical device that genuinely can’t lose power overnight.
Matching Capacity to What You Actually Need to Run
Not every solar generator is sized the same way, and matching capacity to your actual needs matters more than buying on price alone. A rough guide to typical household loads:
- Refrigerator: roughly 150 watts continuous (with higher startup draw)
- CPAP or similar medical device: roughly 30-60 watts
- LED lighting: roughly 10 watts per fixture
- Phone and laptop charging: roughly 20-60 watts combined
Add up what you need running simultaneously, then check a given model’s rated continuous output and total watt-hour capacity against that load — larger capacity units cost more but run longer between recharges.

Why the Solar Panel Piece Matters More Than It Sounds
In a short outage, a fully-charged battery might be all you need. In a multi-day outage — the kind caused by major storms, where crews may take days to restore power — the ability to recharge matters as much as the initial capacity. Gas generators depend on fuel that’s frequently in short supply exactly when you need it most, as gas stations lose power too or see long lines. A solar generator with included panels recharges from daylight, independent of fuel supply chains, which is the practical reason solar has become the default recommendation over gas for home backup in areas prone to extended outages.
What Solar Backup Power Won’t Do
It’s worth being direct about the limits: portable solar generators, even larger models, are not sized to run central air conditioning, an electric range, or an electric water heater — those require far more continuous wattage than a portable unit can realistically supply. For true whole-home coverage during extended outages, a permanent natural gas standby generator is the correct (and considerably more expensive) product. Solar power stations are built for the essentials — refrigeration, medical devices, lighting, and communication — not for running your home exactly as it would run with full grid power.

Frequently Asked Questions
Why can't I run a gas generator indoors?
Gas generators produce carbon monoxide, an odorless gas that can reach fatal concentrations in an enclosed space within minutes. The CDC and CPSC both warn that even a garage with the door open is not sufficient ventilation — gas generators must be run entirely outdoors, well away from windows and doors.
What can I use for backup power indoors instead?
Solar-rechargeable portable power stations produce zero emissions and are safe for indoor use. They store power in a battery, charged either from included solar panels or a standard wall outlet, and output it through regular outlets for your devices and appliances.
What can a solar generator actually power during an outage?
Capacity varies by model, but mid-to-large units are typically sized to run a refrigerator, a CPAP or medical device, phone and laptop chargers, and lighting simultaneously. None of these portable units are sized to run central HVAC or an electric range.
How do I know what size solar generator I need?
Add up the wattage of what you actually need to run during an outage — a refrigerator (~150W), a CPAP (~30-60W), lights (~10W each), and device chargers — and choose a model with enough watt-hour capacity to cover that load for your expected outage length.
Does a solar generator recharge during a multi-day outage?
Yes, if it came with solar panels and there's daylight available. This is the key advantage over gas — fuel supply chains are frequently disrupted during major outages, while sunlight isn't.
