The short version: buy the EcoFlow DELTA 3 Plus. Six AC outlets, 1,800W continuous with a 3,600W surge big enough to start a fridge, a sub-10 ms switchover, and expansion to 5kWh by adding boxes rather than installing anything. If closet space is the real constraint, the Anker SOLIX C1000 Gen 2 packs the same 1,024Wh into a published 15.12 x 8.19 x 9.61 inches and 24.9 lb.
Renting removes almost every option in the backup-power category. A standby generator needs a slab, a gas line and permission. A portable gas generator needs outdoor space you do not have, cannot be run on a balcony, and is banned outright in a great many leases. A transfer switch needs an electrician and a panel you do not own. What is left is a battery you plug into an ordinary outlet — which, as it turns out, covers an apartment outage better than any of the above.
Why a battery is the only option that fits
- No combustion. Carbon monoxide is the reason a fuel generator cannot run indoors, on a balcony, in a stairwell or in a parking garage. A battery has no exhaust at all, so it runs in the room with you.
- No noise. An engine running at 2am in a building with shared walls is a complaint, possibly an eviction. Anker publishes 25dB at 3.3 ft for the SOLIX C300.
- No installation. It plugs into a wall outlet. No panel work, no permission, nothing to remove when you move out.
- It scales by stacking. The DELTA 3 Plus goes to 5kWh and the DELTA 2 Max to 6kWh by adding batteries, which is the renter's version of a bigger system.
If you are weighing the battery against the engine on cost-per-watt-hour grounds, portable power station vs gas generator gives the generator its fair hearing. The conclusion for an apartment, though, is not close — the generator loses on where you are allowed to run it, and that is not a spec you can trade away.
What to power first, in order
An apartment outage has a clear priority list, and it is short. Read the plate on your own appliances; the bands below are categories.
| Load | Typical draw | Daily Wh | Priority |
|---|---|---|---|
| Router and modem | 10-20W | 240-480Wh | First — and the easiest |
| Phone charging, two phones | 10-15W each | 40-80Wh | First |
| LED lamp | 5-15W | 30-100Wh | First |
| Laptop | 45-65W | 150-400Wh | Second |
| Full-size refrigerator | 100-200W cycling 30-50% | 1,000-1,500Wh | Second — the big one |
| Box fan | 40-60W | 300-500Wh | Second in summer |
| CPAP, humidifier off | 30-60W | 240-480Wh a night | First if you use one |
| Microwave | 1,000-1,500W | 100-200Wh per use | Third |
| Electric kettle | 1,000-1,500W | 60-120Wh per boil | Third |
| Space heater | 1,000-1,500W | 8,000Wh+ a day | Not realistic |
That arithmetic is the whole page. If your outages are short — an hour, an evening, a storm flicker — a 1kWh unit handles everything and the fridge stays shut and cold on its own. If your outages run a full day or more, the fridge has to be powered, and that puts you in the 2kWh class with an expansion path. How many watt-hours does a refrigerator use explains how to measure your own fridge rather than trusting the band above, and it is worth doing before you spend.
The spec renters undervalue: switchover time
Every unit here can act as a pass-through UPS: it sits between the wall and your equipment, and when the power cuts it takes over. How fast it takes over is the difference between a router that never notices and one that reboots. EcoFlow publishes under 10 ms on the DELTA 3 Plus, Anker 10 ms on the C1000 Gen 2 and the C300, BLUETTI 20 ms on the AC180.
For a router, a modem and a desk setup, that is genuinely the most useful thing one of these does day to day — far more than the once-a-year outage. Power station as a UPS for wifi and router sets it up properly, and power station vs UPS explains where a conventional UPS is still the better buy.
Balcony solar: what it is actually worth
Worth having if your balcony gets direct sun, worth nothing if it faces a wall. A portable panel propped on a balcony rail is not a roof array: you get a few hours of good angle, shading from the building above, and a derate on top. The honest figure is a fraction of the panel's rating. How much solar input do you need has the arithmetic, and the panel roundup covers what folds up small enough to store in a closet.
What makes it worth doing at all is the input ceiling on the unit. The DELTA 3 Plus takes 1,000W across two inputs; the DELTA 2 Max takes 1,000W; the Anker C1000 Gen 2 takes 600W. A high ceiling means a balcony's short good window still moves the needle. Check your lease and your building's rules before you hang anything over a rail.
How to choose between these four
- One box that can become three — EcoFlow DELTA 3 Plus: six AC outlets, 3,600W surge, expands to 5kWh.
- The smallest thing that still does 1,024Wh — Anker SOLIX C1000 Gen 2: published dimensions, 24.9 lb, 49-minute recharge.
- Outages that run past a day — EcoFlow DELTA 2 Max: 2,048Wh, expands to 6kWh.
- Wifi, a laptop and a lamp — Anker SOLIX C300: 288Wh, 9.1 lb, 10 ms switchover.
- You are in a house, not an apartment — best portable power stations for home backup includes the 240V units an apartment cannot use.
And if you are not yet sure a power station is the right purchase at all, are portable power stations worth it works through the cases where the answer is no — including the one where a cooler full of ice and a phone bank is the cheaper, better plan.
What we have not done
We have not run an apartment through an outage on any of these units, measured a real switchover or timed a fridge on battery. Every specification above is the manufacturer's own published figure, linked below; appliance draws are nameplate bands you should check against your own equipment; and every calculation is written out so you can substitute your numbers. We also do not interpret your lease — check it before buying anything you intend to run on a balcony. How we choose.
The picks in full
1. Best overall for a rented apartment
EcoFlow DELTA 3 Plus
- 1,024Wh
- LFP (LiFePO4)
- 1,800W continuous / 3,600W surge
- 27.6 lb
- 1000W
- 4,000 cycles to 80%+ capacity
- Full in 56 min (1,500W AC input)
- 5 years
Six AC outlets in a 27.6 lb box is the right shape for an apartment outage, because what you are actually powering is a lot of small things in one room: a router, a laptop, phone chargers, a lamp, a fan, and the fridge on an extension cord.
EcoFlow publishes 1,024Wh, 1,800W continuous with a 3,600W surge — the highest surge figure in its class, and the one that lets a fridge compressor start without tripping — a sub-10 ms UPS switchover, a full recharge in 56 minutes at 1,500W, and 4,000 cycles to 80% or better.
The two specs that make it the apartment pick specifically are expansion to 5kWh, which matters when you cannot install anything permanent and have to grow by adding boxes, and 1,000W of solar input across two MPPT inputs, which is the highest here and the only realistic way to use a balcony that gets sun.
Reasons to buy
- Six AC outlets — the right port count for one room
- 3,600W surge, highest in its class
- Under 10 ms UPS switchover
- Expands to 5kWh without any installation
- 1,000W solar input across two inputs
Reasons to avoid
- 27.6 lb and a 15.7 x 8.0 x 11.2 in footprint to store
- 1,024Wh is one fridge-day, not three
- No 240V output — nothing hard-wired
- Costs more than the plain DELTA 3 for solar input you may never use
Buy it if: a renter who wants one box that can become three.
Skip it if: you charge only from the wall — buy the plain DELTA 3.
2. Smallest footprint for the capacity
Anker SOLIX C1000 Gen 2
- 1,024Wh
- LiFePO4 (InfiniPower LFP)
- 2,000W continuous / 3,000W surge
- 24.9 lb
- 600W
- 80% capacity after 4,000 cycles
- Full in 49 min (UltraFast, 1,600W max input)
- 5 years
In an apartment, where the thing lives matters as much as what it does. 15.12 x 8.19 x 9.61 inches and 24.9 lb for 1,024Wh is the most capacity per cubic inch of closet here, and 41.1Wh per pound means you can move it between rooms without ceremony.
Anker publishes 2,000W continuous with a 3,000W surge — the widest appliance envelope per pound on this site, which in a kitchen means a microwave or a kettle is actually on the table — a full recharge in 49 minutes, a 10 ms switchover and 80% capacity after 4,000 cycles.
Two AC outlets is the compromise, and in an apartment outage it bites: a power strip is mandatory. It also does not expand, so the capacity you buy is the capacity you keep.
Reasons to buy
- Published dimensions, and the smallest footprint for 1,024Wh here
- 2,000W continuous, 3,000W surge
- Full recharge in 49 minutes
- 80% capacity after 4,000 cycles
- 10 ms switchover; 5-year warranty
Reasons to avoid
- Only two AC outlets
- Not expandable
- 600W solar input
- 1,024Wh is the smallest battery in its class here
Buy it if: a small apartment where storage space is the constraint.
Skip it if: you need more than two things plugged in directly.
3. Best for an outage that lasts
EcoFlow DELTA 2 Max
- 2,048Wh
- LFP (LiFePO4)
- 2,400W continuous
- 50.7 lb
- 1000W
- 3,000 cycles to 80% capacity
- 2.3 hr; 800W car/alternator charging
- 5 years
2,048Wh is the capacity where an apartment outage stops being a crisis. A full-size fridge is roughly 1,000-1,500Wh a day, so this unit is about a fridge-day with the router, phones and a lamp alongside — and it expands from 2kWh to 6kWh with up to two extra batteries.
EcoFlow publishes 2,400W continuous, 15 outputs including six AC, a 2.3-hour wall recharge, 1,000W of solar input, a sub-20 ms switchover and 3,000 cycles to 80%. For a renter the expansion path is the point: three stacked boxes need no landlord permission and no electrician.
50.7 lb is a lot to store in a one-bedroom, and EcoFlow publishes no surge figure and no dimensions for this model on either of its pages, so we state neither rather than guessing.
Reasons to buy
- 2,048Wh — about a fridge-day plus essentials
- Expands from 2kWh to 6kWh
- 2,400W continuous; six AC outlets among 15
- 1,000W solar input; under 20 ms switchover
- 5-year warranty
Reasons to avoid
- 50.7 lb
- No surge figure or dimensions published for this model
- 2.3 hours to recharge
- Hard to store in a small apartment
Buy it if: an area where outages run past a day.
Skip it if: storage space is the binding constraint.
4. Best for a desk, a router and a first unit
Anker SOLIX C300
- 288Wh
- LFP (LiFePO4)
- 300W continuous / 600W surge
- 9.1 lb
- 100W
- 80% in 50 min
- 5 years
288Wh and 9.1 lb with a 10 ms UPS switchover. If what you actually need is for the wifi, the modem and a laptop to ride through a flicker or a one-hour cut, this is the whole answer, and it sits behind a desk instead of in a closet.
Anker publishes 300W continuous with a 600W SurgePad, four USB-C ports up to 140W, two USB-A, a 120W car socket, an 80% recharge in 50 minutes and 25dB at 3.3 ft. That last figure matters in a studio: it is quiet enough to leave running in the same room you sleep in.
300W continuous means no kitchen appliance, no fridge compressor and no space heater. Anker also publishes no cycle rating and no dimensions for this model. This is a router UPS with ambitions, not a house backup.
Reasons to buy
- 9.1 lb and small enough to live behind a desk
- 10 ms UPS switchover
- Four USB-C ports including 140W
- 80% recharge in 50 minutes; 25dB at 3.3 ft
- 5-year warranty
Reasons to avoid
- 300W continuous — no fridge, no kettle
- No cycle-life rating published
- 100W maximum solar input
- 288Wh is hours, not a day
Buy it if: wifi, a laptop and a lamp through a short cut.
Skip it if: the fridge is the reason you are shopping.
