How long will they run?

For the runtime math in this section, take 85% of the listed capacity as the energy you can actually use. Eighty-five percent of the listed 3,840 Wh gives 3,264 Wh of usable energy. A 200 W load runs for about 16.3 hours on that energy.

Both hold the same capacity, so a 100 W load runs for about 32.6 hours on either one. The Elite 400 packs far more energy per pound, at about 44.7 Wh per pound against 28.1.

How to choose

Pick the Elite 400 when you want a rolling 3,840 Wh backup with 2,600 W of output. Pick the F3800 Plus when you need 6,000 W, 240V power, and room to add batteries. Check each station’s output against the nameplate of the appliances you plan to run before you buy.
