Technical comparison · Home backup
One is carried by hand, the other is an apartment-scale store: about 1 kWh and 12 kg against 4.6 kWh and 55 kg. The choice comes down to how much energy is needed and how much weight can be moved.

Most capable Flat-sized (3–8 kWh)
Highest technical score among the 6 sheets in the Home backup category (flat-sized tier): 84/100.
How we assign awards →The differences that matter
- 1 kWh vs 4.6 kWh of capacity → at full load the first lasts about half an hour, the second a little over an hour while delivering more than twice the power.
- Solar input 500 W vs 3,000 W → 1 kWh refills from the sun in a couple of hours; 4.6 kWh takes a similar time, but you need panels for 3,000 W.
- Emergency power with a short pause (30 ms) vs continuous (13 ms) → only the second switches to battery without interrupting what it feeds.
- Warranty 5 years vs 3 → the small unit is covered for longer.

Which one to choose
Choose EcoFlow DELTA 2 if…
you need power you can take to where you work or where there is no grid, for loads up to 1,800 W. At that output the battery lasts a little over half an hour, so it suits short jobs or lighter loads. The trade-off is the reserve: just over 1 kWh does not cover a day of average loads.
Choose Zendure SuperBase V 4600 if…
you want to run several appliances at once, up to 3,800 W, from six mains outlets, and cover several hours of average loads. In return you take on a 55 kg unit that you are unlikely to move for every use.
