Practical helpers you can use in under a minute.
An instant converter for watt-hours and amp-hours across common battery voltages, built to help readers compare portable power station specs with battery bank terminology. It keeps the math simple while clearly stating the assumptions.
Use ToolEstimate how many effective sun hours or days a balcony solar setup needs to recharge a portable power station between two battery percentages. It is tuned for practical urban use where panel angle, shading, and losses matter.
Use ToolA step-by-step planner that totals the watt-hours needed for a realistic outage scenario and turns device lists into a portable power station sizing target. It saves progress locally, prints cleanly, and focuses on practical backup loads rather than abstract specs.
Use ToolEstimate real-world runtime for a portable power station based on battery size, appliance watt draw, usable capacity, and inverter losses. Built for readers who want planning clarity instead of optimistic marketing math.
