Planning
Calculate the load, understand fuel and runtime, and define what the backup plan must accomplish.
Sizing 101
8 min readWhat size generator do I need?
A practical method for adding running watts, startup surges, and enough headroom to choose a useful generator size.
Add the running watts of everything you will use at once, add the single largest extra startup surge, then leave roughly 15–25% headroom.

Fuel guide
10 min readGas vs. propane vs. battery power
Compare output, storage, runtime, noise, maintenance, and indoor-use constraints before choosing a power source.
Gas usually delivers strong portable output, propane stores more cleanly, and batteries are quiet and can be used indoors—but each solves a different outage problem.

Home backup
9 min readCan a generator run my whole house?
Learn the difference between powering essential circuits and supporting an entire home, including transfer equipment and large electric loads.
A portable generator can often cover selected essential circuits, but “everything at once” may require load management or a professionally installed standby system.

Runtime planning
9 min readHow long will a generator run?
Estimate engine-generator or power-station runtime without confusing a best-case manufacturer rating with the time your own load will receive power.
Runtime depends on average load, not only generator size: use the published load condition for engine ratings and usable watt-hours for battery estimates.

Technology
Understand the design choices that change output quality, sound, weight, efficiency, and cost.
Technology guide
8 min readInverter vs. conventional generator
Compare how inverter and conventional portable generators produce power, then choose based on output, sound, portability, efficiency, and price.
Choose an inverter generator when lower-load efficiency, portability, and lower sound matter; choose a conventional open-frame model when high output per dollar is the stronger priority.

Installation & safety
Separate appliance-level connections from household wiring and know when qualified installation is required.
Safe connection planning
9 min readTransfer switch vs. extension cords for a portable generator
Understand the safe boundary between directly powering selected appliances and connecting a portable generator to household wiring.
Heavy-duty cords can feed selected appliances directly; powering home circuits requires approved transfer equipment installed for the exact electrical system.

Build a model-specific readiness routine for inspection, exercise, oil, air filters, fuel, batteries, storage, and pre-outage testing.
The owner’s manual controls every interval and procedure; use a written log so fuel treatment, oil service, battery care, and exercise do not depend on memory.
