When it comes to portable power stations, the market is brimming with options for the avid adventurer, the emergency planner, or the eco-conscious homeowner. Two notable models in this diverse ecosystem are the EcoFlow Delta 2 Max and the Jackery 290. Each offers unique features tailored to different needs. But which one is right for you? Let’s energize our understanding with a direct comparison.
Capacity and Battery Life
The Delta 2 Max boasts a formidable 2016Wh base capacity that can be expanded up to a staggering 6kWh, while the Jackery 290’s 290Wh capacity is tailored more towards lightweight applications. With over 3000 cycles to 80% capacity, the Delta 2 Max is a long-term player, especially next to the Jackery’s respectable 1000 cycles.
Power Output and Device Management
For power-hungry appliances, the Delta 2 Max shines with an AC output of up to 3400W and the capability to run 15 devices simultaneously. In contrast, the Jackery 290 offers a more modest 200W continuous output, suitable for smaller devices and occasional use.
