These are the two names most buyers end up choosing between, and the difference is not marketing. Jackery consistently builds the lighter unit; EcoFlow consistently builds the faster-charging, more expandable one.
To keep the comparison concrete we use each brand's mainstream 1kWh unit. All figures are manufacturer specifications; no prices or marketplace data appear here.

Product A
Jackery
Jackery Explorer 1000 v2 Portable Power Station
Upper Mid-Range ($$$)
Best for: buyers who carry the unit and want the lightest 1kWh option
Jackery's second-generation 1kWh unit: 1070Wh of LiFePO4 behind a 1500W inverter with a 3000W surge rating, in a lighter body than most rivals of the same capacity and with an emergency super-charge mode.
Product B
EcoFlow
EcoFlow DELTA 3 Portable Power Station
Upper Mid-Range ($$$)
Best for: buyers who want the fastest recharge and an expansion path
The current-generation replacement for the DELTA 2. Same 1024Wh LiFePO4 capacity and 1800W inverter, but with substantially faster AC recharging, a quicker UPS-style switchover and a quieter charging profile.

Two different design priorities
Jackery builds for the person who moves the unit: lighter chassis, simple controls, a high surge rating so appliances start without fuss.
EcoFlow builds for the person who plugs the unit in: very fast recharging, fast switchover, expansion batteries and deeper app control.
Inverter output and surge
EcoFlow's 1800W continuous rating beats Jackery's 1500W, which matters if you plan to run larger appliances for a sustained period.
Jackery answers with a 3000W surge rating, which is about starting motors and compressors rather than running them. Both approaches work; they solve different problems.
Expansion decides long-term value
If there is any chance you will want more capacity later, EcoFlow's expandable platform is the safer purchase. Jackery's fixed pack means a second unit rather than a bigger one.
If the unit exists to go camping, expansion is irrelevant and the weight saving is worth more than the growth path.
Ecosystem and support
Both brands have large support networks, published documentation and wide accessory ranges, including their own solar panels.
Neither choice is a support risk, which is exactly why the decision comes back to weight against expansion.
