Buying Guide: Apartment Backup Power
Keep these points in mind before you buy.
Battery power only indoors
Gas generators make carbon monoxide and must stay outdoors far from openings, so apartment dwellers should rely on battery power stations and UPS units.
Size it in watt-hours
Divide a battery’s watt-hours by your device’s watts, then take off about 15% for conversion losses to estimate runtime.
UPS switchover
A UPS or UPS mode switches to battery in milliseconds so a router or computer does not reboot when the power blinks.
Recharge with solar
A folding solar panel lets you recharge a power station during long outages. Output depends on sun angle and weather.
Apartment Outage Tips
Stay powered:
- Keep a station charged.
- Plug the router into a UPS.
- Use LED lanterns.
- Check building rules.
