Recharging with solar
The EcoFlow Delta 3 Max accepts up to 500W of solar input. In real conditions that harvests about 1.9 kWh on a sunny day (5 peak-sun hours), or about 750Wh with one 200W panel.
Tips
- A typical laptop battery holds 50–70Wh. Charging over USB-C PD is more efficient than using the laptop's AC brick.
- Running it from the EcoFlow Delta 3 Max’s DC port instead of the AC outlet avoids inverter losses: about 143Wh more usable energy.
- The EcoFlow Delta 3 Max uses LiFePO4 (LFP) cells, rated for thousands of cycles, so running it down daily won’t wear it out quickly.
