Buying Guide: Choosing Your Battery Charging Generator
Power Output and Capacity
The most critical factor is matching the generator’s output to your devices. You need to know both the running watts and the peak watts. Running watts are the continuous power it can supply.
Peak watts are for the initial surge when a device starts. For charging batteries, focus on the running wattage of the AC outlets and the amperage of the USB ports. A unit like the Westinghouse iGen400s is perfect for small electronics, while the larger dual fuel model can handle power tools and home appliances simultaneously.
Fuel Type and Runtime
Your choice of fuel directly impacts convenience, cost, and runtime. Traditional gasoline generators offer high power but require fuel storage. Dual fuel models, like the Westinghouse 12500 Watt, provide flexibility by running on gasoline or propane.
Propane can be stored for longer periods and burns cleaner. For purely electronic charging, a lithium power station like the iGen400s requires no fuel at all, just an electrical outlet or solar panel to recharge its internal battery. Consider how long you need power between refuels or recharges.
Portability and Intended Use
<!–Where will you use the generator? A heavy-duty model is ideal for a fixed home backup location, perhaps paired with a transfer switch. If you need power on the go for camping, job sites, or outdoor events, weight and size become major factors.
The Westinghouse iGen400s is lightweight and emits no fumes, making it safe for indoor use. For more demanding mobile power needs that still require clean output, our review of the best Westinghouse inverter generators for off-grid living offers further insights.
