Two high-capacity bundles pair a power station with an expansion battery: the EcoFlow DELTA Pro Ultra with inverter, 6,144 Wh and 6,900 W, and the Bluetti Apex 300 with expansion battery, 5,529.6 Wh. Each item is detailed on its product page.
Bluetti
EcoFlow
A bundle combines a power station with at least one extra battery, which raises the stored energy without separate purchases. The two sets offered here hold several thousand watt-hours: enough to supply a building site, a cabin or part of a house during an outage, depending on the devices connected.
To size your need, add up the power of the devices used at the same time, then estimate how long they will run. The output power must cover the total, while the capacity in Wh determines running time. Also check the weight, the space available and how the whole set is recharged. These sets are a significant investment and heavy equipment; take the time to read the full product page. Payment is made by secure bank transfer, and after-sales support remains available throughout the 2-year legal guarantee period.
