The small and lightweight Westinghouse iGen400s portable power station is made for indoor and outdoor use for both emergencies and convenience. It delivers safe, quiet, fume-free power and charges to 80% in 2 hours from a 120V outlet with the included USB-C cable, if using a 100W AC power adapter for the fastest charge. No AC power adapter is included. Around the home, it's an easy way to power everyday electronics, phones and laptops if you don't want to deal with hard to reach outlets, extension cords, and when spending time on the deck or in the yard. Get reliable emergency power during home blackouts—it's especially good for apartment dwellers experiencing building-wide power issues. A top handle makes it easy to carry for activities like camping, RVs and tailgating. Ideal for in-car use during road trips because it's quiet and simple to operate for all. Includes a tri mode LED flashlight and an emergency flasher. With 184 watt hours of lithium battery capacity, 200W running and 400W peak output, the iGen400s has multiple connection options like dual AC outlets, high speed USB-C and USB-A ports, plus a 12V DC outlet and car charger adapter to keep many devices running at once. An LED display shows data like battery level, recharging time and watts out, removing guesswork. Built in protections provide safety, better operation and long battery life for many cycles of maintenance-free power, backed by a 2 year limited warranty and lifetime Westinghouse technical support.
