WFH backup is the same shape as fridge-and-router blackout backup but with an extra constraint: your home office has to remain workable. That means UPS-grade transfer is non-negotiable (a 200ms gap reboots the laptop and crashes the video call), fan noise has to stay under 50 dB at typical load (you're on Zoom), and the unit has to keep running for 4-8 hours so you can finish the workday before deciding if you need a generator. Capacity sizing: a 27" monitor draws 50W, a laptop 60W, a docking station 15W, router + modem 25W, a USB-C external drive 10W, a desk lamp 10W. Total ~170W mixed, which is 1300 Wh over an 8-hour workday plus station idle.
The smart-monitoring feature stops being a gimmick in this use case. EcoFlow and Bluetti both ship app-based runtime estimation that updates as your load changes — useful when you're trying to decide whether to push through a final hour of meetings or close the laptop. Jackery's app-side experience lags both — workable but noticeably less polished. App-supported is also a hint at general firmware/UI quality, which matters more for a unit you'll touch weekly than one that lives in the closet.
Avoid the temptation to size up to 3+ kWh for this use case. The marginal value of going from 1500 Wh to 3000 Wh is small (an 8-hour workday is well within 1500 Wh budget), and the bigger unit costs $500-1000 more, weighs 12+ kg more, and takes 2× the floor space. The 1500-2000 Wh tier is where WFH backup hits the price-per-day-of-coverage sweet spot.
