Apartment backup power has different priorities than a house: no yard to run a generator in, less storage space, and often a stricter power budget since central appliances (electric stove, in-unit HVAC) may not be something you're trying to cover at all.
What apartment living rules out — and what that means
A gas generator is a non-starter in an apartment: it can't run indoors or on a balcony safely (see our carbon monoxide safety guide), and most leases prohibit fuel storage anyway. That leaves a battery-based power station as the realistic option — which is good news, since they're also the quieter, lower-maintenance choice.
Sizing for an apartment's realistic priority list
| Priority | Suggested capacity |
|---|---|
| Phone, laptop, lights, Wi-Fi router | 300-500 Wh |
| + mini fridge or a few hours of a full fridge | 800-1,000 Wh |
| + CPAP or a medical device overnight | 1,000-1,500 Wh |
| + a fan or small space heater for comfort | 1,500-2,000 Wh |
Most apartment situations land in the 500-1,000Wh range — see our under-$500 buying guide if you're in the lower end of that range. Run your specific list through the free wattage calculator to confirm before buying.
Two apartment-specific factors worth weighing
- Physical size and storage — a compact unit that fits in a closet or under a desk matters more in an apartment than in a garage; check dimensions, not just capacity, before buying
- Charging without a dedicated outlet — most apartments don't have a 240V outlet, so confirm the unit charges at a reasonable speed from a standard 120V wall outlet if fast AC charging matters to you
