Jackery's HomePower 2000 Plus v2 portable power station costs $1,069 at Amazon as of November 6, down $130 from its $1,199 list price, for a limited time.
That is an 11% discount on a unit with 2,400W of output and 2,048Wh of capacity. Watt-hours measure stored energy, so in theory the battery could run a 200W load for about 10 hours, before conversion losses. The capacity can be expanded to 12kWh for home backup during outages. Two software features, Smart Energy Management and Priority Routing, send available power to the most important appliances first.
The battery uses lithium iron phosphate (LFP), a chemistry that gives up some energy density in exchange for a longer life. Jackery rates it for more than 6,000 charge cycles and says that equals about 16 years of use. The company also says the unit is 34% lighter than the previous generation and easier to move than comparable expandable 2kWh units. Both are manufacturer claims.
The arithmetic is easy to check. At $1,069, the base unit costs about 52 cents per watt-hour, against roughly 59 cents at list price. And 6,000 cycles over 16 years implies close to one full charge and discharge a day. A backup unit that only runs during outages will rarely come near that pace, so for that kind of buyer the cycle rating matters less than the upfront price.
The $1,069 covers the main unit, and the deal details don't say what expansion batteries cost. For now, the 12kWh figure describes what the system can grow into, not what this price buys.
