The EcoFlow 4kWh Get Set Power Kit sits between the entry 2 kWh version and the heavier 5 kWh flagships, pairing the Get Set Power Hub backbone with two 2.048 Wh LFP batteries for a combined 4.096 Wh. It is aimed at couples who spend a few weeks a year off-grid in a compact van or small caravan, where two lighter packs are easier to install and rearrange than one heavy block. Both packs use the same LiFePO₄ chemistry rated for 3.500 cycles to 80 % capacity.

• 4.096 Wh usable storage split across two matched 2.048 Wh packs, giving two to three days of light off-grid use.
• Up to 4.800 Wp of solar input across three MPPT strings — a modest van roof can still fully recharge the bank on a clear day.
• 1.000 W alternator charging returns significant energy during transfer days without stressing the starter battery.
• 3.000 W AC input from shore power tops up the full bank in under two hours at a campsite.
• Smart Generator input up to 1.800 W acts as a fallback for rainy weeks or cold winter periods with poor solar yield.
• Modular batteries can be split across two locations in the vehicle to balance weight over the axles.
