01 Portable backup power / US guide

Portable power, sized for the situation.

Start with the load, not the logo. This field guide helps you work backward from a refrigerator, CPAP machine, Starlink Mini, RV, sump pump or laptop to the output, battery and charging features you actually need.

A portable power station is a battery, inverter, charger and control system in one enclosure. The useful question is not “which brand is best?” It is “what must run, for how long, and under what conditions?” Use the paths below to begin with a concrete decision.

The two numbers that decide most purchases

Output / WCan it start and run the load?

Continuous output covers the sustained demand. Surge or peak output covers short startup events from motors and compressors.

Battery / WhHow long can it run?

Watt-hours are the energy tank. Usable runtime is lower after inverter losses, conversion losses and the reserve you keep in the battery.

What to verify on a product sheet

Field	Why it matters	What to write down
Continuous AC output	The sustained ceiling for the inverter.	W and, if relevant, voltage / outlet type.
Surge / peak output	Motor and compressor loads can need more at startup.	Peak W and the stated duration, if given.
Battery capacity	The starting point for runtime estimates.	Wh, plus whether the figure is nominal or usable.
AC, solar and vehicle charging	Recharge time depends on the input path.	Input wattage, connector, voltage range and included parts.
Ports and protection	Compatibility is more than total watts.	USB-C PD, 12V output, GFCI, pass-through and temperature limits.

Specifications are only useful when they are attached to your load. A large battery cannot overcome an undersized inverter, and a powerful inverter does not create more energy. Keep those two constraints separate.
