Gas generators are not an option in an apartment. You cannot run them indoors, you cannot run them on a balcony in most buildings, and the carbon monoxide risk is real. What you can do is buy a portable power station – a sealed lithium battery that charges from your wall outlet, runs your devices silently, and stores in a closet until you need it.
This guide covers five picks across distinct categories, because the right unit for a CPAP machine is not the same as the right unit for a fridge, and a renter on a $200 budget has different needs than someone preparing for extended hurricane season outages.
Every unit here uses LiFePO4 battery chemistry – the only type that does not off-gas, does not overheat, and is safe to run in an enclosed apartment space. All runtime numbers are calculated from actual wattage draws, not manufacturer estimates.

Best Overall: EcoFlow River 2 Pro
Why it wins: The EcoFlow River 2 Pro is the pick Wirecutter chose as their overall best portable power station, and for apartment renters specifically it earns that ranking. At 768Wh it holds nearly three times the capacity of the Jackery 300 Plus at only two-thirds of the Anker SOLIX’s price. The 70-minute recharge time is the feature that separates it from everything else in its class – if your power comes back for 90 minutes in the middle of a multi-day outage, the River 2 Pro will be fully charged and ready before it cuts out again.
What it handles in a real outage: Phones and laptop all day. Fridge for 4-5 hours – long enough to get through an overnight blackout without food loss. CPAP for two full nights. A fan or box heater in short bursts. It does not handle a space heater continuously (750W+) and should not be expected to.
The Bluetooth app lets you monitor wattage draw in real time, set a charging limit to protect battery longevity, and cap wall charging speed to avoid tripping older apartment breakers. That last feature matters in buildings with 15-amp circuits.
Who should not buy it: If your outages are consistently under 4 hours and you only need devices charged, the Jackery 300 Plus does that job at half the price. And if you’re in a hurricane zone expecting 48-72 hour outages, you need the Anker SOLIX.

Best Budget Pick: Jackery Explorer 300 Plus
Why it wins this category: At $299 the Jackery Explorer 300 Plus is the only unit on this list you can buy without a second thought about the price. It is also the lightest at 8.8 pounds – you can pick it up with one hand, move it between rooms, and store it on any shelf in your apartment. For renters who want a starter unit and are not trying to run a full kitchen, it covers the essentials cleanly.
The upgrade that matters: The “Plus” in the name refers to the battery chemistry upgrade from the original 300. The original used NMC lithium. The Plus uses LiFePO4 with a 2,000-cycle lifespan – roughly 5-6 years of weekly use before hitting 80% capacity. For a device that sits in storage most of the time and rarely gets cycled, that chemistry will outlast the decade.
Best use case for apartment renters: Short outages under 6 hours. CPAP users will get a full night on this unit alone. Remote workers get a full laptop workday. Anyone who just needs devices charged and lights on through an overnight blackout does not need anything larger.
Honest limitation: It will not keep your fridge cold through a multi-hour outage. 1.6 hours of fridge runtime is enough to cover a brief blackout but not a serious one. If fridge protection is the priority, spend the extra $200 and get the River 2 Pro.

Best for Extended Outages: Anker SOLIX C1000 Gen 2
Why it wins this category: The Anker SOLIX C1000 Gen 2 is the unit for renters who live in hurricane zones, areas with aging grid infrastructure, or anywhere that 24-72 hour outages happen with any regularity. At 1,056Wh it has the capacity to run a full-size fridge for 6 hours, power a full device setup for a working day, and still have charge left over. The 1,800W output means there is nothing in a standard apartment it cannot run – including appliances that would trip the output limit on the River 2 Pro.
The recharge speed is the hidden advantage: At 49 minutes from 0% to 100%, it recharges faster than either of the other units on this list. In a rolling blackout scenario where power comes back briefly, a 49-minute window is enough to get a full recharge. The River 2 Pro needs 70 minutes. The Jackery needs 2 hours.
The trade-off is price and weight: At $999 it costs twice the River 2 Pro, and at 27.6 pounds it is heavier. It has a handle and rolls, but it is not something you will casually move around your apartment. If your outages are typically short and your needs are light, you are buying capacity you will never use.
Who should buy this: Florida and Gulf Coast renters ahead of hurricane season. Renters with medical equipment that cannot be interrupted. Anyone whose past outages have exceeded 12 hours and who does not want to repeat the experience of spoiled food and dead devices.

What to Add: Solar Input
All three units accept solar input through their DC port. For a sustained outage that lasts multiple days, a foldable solar panel on your balcony or near a south-facing window will slowly recharge the unit during daylight hours – effectively giving you unlimited runtime as long as the sun is out.
The BLUETTI 350W Foldable Solar Panel is compatible with all three units and folds flat for closet storage. Solar recharge is not fast – expect 4-6 hours to fully recharge any of these units on a clear day – but it removes the grid dependency entirely during an extended outage.

One More Thing: Monitor Your Fridge Temperature
A power station keeps your fridge running as long as the battery holds. But without a thermometer inside the fridge, you’re guessing when food is at risk. The ThermoPro Wireless Fridge Thermometer monitors both compartments from your phone and alerts you when the temperature rises above the safe threshold – so you know exactly when to start conserving battery or make the call to eat the perishables.

Can You Use a Portable Power Station in an Apartment?
Yes – and it is the only type of backup power that is actually safe to use in an apartment. Gas generators produce carbon monoxide and cannot be run indoors, in enclosed garages, on balconies, or within 20 feet of an open window under most building codes and fire safety regulations. Propane generators carry the same risk.
Portable power stations are sealed lithium battery units. They produce zero emissions, zero fumes, and zero noise. You plug them into your wall outlet to charge, then run your devices off them during an outage – the same way a large phone battery works, just significantly bigger. There is no installation, no permit, and no lease violation involved in owning one.
The one consideration for apartments is battery chemistry. Older NMC lithium batteries can swell, overheat, or in extreme cases catch fire when damaged or improperly charged. Every unit on this list uses LiFePO4 (lithium iron phosphate) chemistry, which is thermally stable, does not off-gas, and has a significantly lower risk profile for enclosed storage – which matters when your storage space is a closet, not a garage.
How Long Will a Portable Power Station Last During a Power Outage?
It depends entirely on what you’re running and how much capacity the unit holds. The runtime tables earlier in this article give specific numbers for four common load scenarios – but here is the short version:
- Devices only (phone, laptop, router – ~95W): Jackery 300 Plus lasts 2.6 hours. EcoFlow River 2 Pro lasts 6.9 hours. Anker SOLIX C1000 lasts 9.5 hours.
- Full-size fridge only (~150W average): Jackery 300 Plus lasts 1.6 hours. EcoFlow River 2 Pro lasts 4.4 hours. Anker SOLIX C1000 lasts 6 hours.
- CPAP machine only (~30W): All three units cover at least one full night. The EcoFlow and Anker cover two or more nights without recharging.
- Fridge + all devices + lights (~220W): Jackery 300 Plus lasts about 1 hour. EcoFlow River 2 Pro lasts 3 hours. Anker SOLIX C1000 lasts 4 hours.
The most important thing to understand about runtime is that a fridge does not draw its rated wattage continuously – it cycles on and off. A fridge rated at 150W might only draw power 30-40% of the time, which can effectively double the runtime estimate above. The numbers in this article use the average draw, which is the more conservative and reliable figure.

How to Charge a Portable Power Station in an Apartment
The short answer: plug it into any standard wall outlet. That’s it. No special wiring, no electrician, no landlord permission required. Every unit on this list charges from a standard 120V household outlet using the included cable – the same outlet you use for a phone charger or a laptop.
A few things worth knowing for apartment use specifically:
- Charge speed varies by outlet and circuit. Older apartments with 15-amp circuits may charge the unit slightly slower than a 20-amp circuit. The EcoFlow River 2 Pro’s app lets you cap the charging draw to 600W to avoid tripping older breakers – useful if you’re on an older building’s electrical system.
- Charge it before you need it. Keep the unit between 20-80% charge during storage to maximize battery longevity. Charge it to 100% when a storm or grid event is forecast.
- Solar is an option for balcony apartments. All three units accept solar panel input, which lets you recharge during a sustained outage without grid power. A foldable panel on a south-facing balcony or near a window works – it is slow, but it removes the grid dependency entirely.
- Do not charge in a closed cabinet. These units generate mild heat during charging. A shelf or floor in an open area of your apartment is fine. A sealed cabinet or enclosed closet while charging is not ideal.
Are Portable Power Stations Safe to Use Indoors?
Yes – with the right battery chemistry. This is the question renters ask because they know gas generators are dangerous indoors, and they’re right to ask it before buying any backup power device.
The safety of a portable power station depends on its battery type. Here is the practical difference:
- NMC lithium (older, cheaper units): Thermally unstable under stress, damage, or overcharging. Can swell or in rare cases vent toxic gases. Fine in a garage or outdoor storage; less ideal in a bedroom or living room closet.
- LiFePO4 lithium (all units in this article): Thermally stable across a wide temperature range. Does not off-gas under normal use or standard damage scenarios. The chemistry used in medical devices and electric vehicles for indoor applications. This is what you want in an apartment.
Beyond battery chemistry, all three units on this list have built-in battery management systems (BMS) that cut power if the unit overheats, overcharges, or detects a short circuit. They are UL or ETL listed for indoor use. You can store them in a closet, charge them in your living room, and run them in your bedroom without concern.
The one thing to avoid: storing any lithium battery device in temperatures above 113°F (45°C) for extended periods. A hot car in summer, a south-facing metal storage unit in direct sun – those conditions stress any lithium battery. A climate-controlled apartment is the ideal storage environment.
