Portable Power Stations, Compared by the Spec Sheet
Compare portable power stations, solar generators, and off-grid tech by capacity, output, and recharge time — with runtime math from published specs, not marketing copy.
Portable Power
Start With the Question, Not the Product
Every guide here answers one operator question with a formula and a spec sheet. No hands-on testing is claimed anywhere on this site — each number reconstructs from published specs, a 0.85 inverter factor, and a dated price check. Pick the question.
Which portable power station fits my trip or outage?
Our best portable power stations guide works through camping, overnight CPAP, and refrigerator backup with capacity math and a shortlist for each job.
Size your combined devices in Power LabHow many nights will a power station run my CPAP?
Sizing by machine wattage, humidifier on or off, and a nights-per-station table built from rated capacity × 0.85.
CPAP runtime calculatorWhy does my fridge trip a 1000W power station?
Startup surge is 3-10× running watts. Size for the spike, not the nameplate.
Appliance surge sizerCan a power station replace a UPS?
Advertised switchover is 10-30ms depending on model. Routers ride it out; most desktop PCs do not.
Why does my solar generator charge slower than advertised?
MPPT voltage windows, amperage caps, and the 0.65 field factor behind every panel rating.
Solar recharge calculatorLiFePO4 or NMC?
Compare cycle counts at the same remaining-capacity threshold, alongside weight and charging needs.
How many solar panels do I need?
The sizing formula, with the planning multiplier that turns rated watts into a realistic daily harvest.
