Comparing the EcoFlow DELTA Pro 3 Alternatives
EF EcoFlow DELTA Pro 3.6kWh with 2x400W Solar
This model shifts the battery from a vertical tower to a horizontal layout, measuring 25 inches wide but only 11.2 inches tall. It weighs 99 pounds, which is 16 pounds lighter than the original. The capacity is listed as 3.6kWh, slightly less than the 4096Wh in the reference unit. Both include 2x400W solar panels and offer solar charging features. The horizontal design may fit better in low-clearance storage spaces. You gain a more stable footprint but lose the vertical handle convenience. Choose this if you need a lower profile for garage shelving or transport in vehicles with height limits.
EcoFlow DELTA 3 Ultra Plus 3072Wh with 2x400W Solar
The DELTA 3 Ultra Plus offers 3072Wh of capacity, which is lower than the 4096Wh in the original. It does not list a weight in the provided data, but its dimensions are 24.1 inches long and 15.6 inches high. It includes 2x400W solar panels for charging. This unit targets users who need expandable storage for heavy appliances. You get a more compact footprint than the tall original tower. The trade-off is reduced total energy storage. Select this alternative if you prioritize a lower center of gravity and expandability over maximum raw capacity in a single unit.
BLUETTI Apex 300 5.5kWh Solar Generator
The BLUETTI Apex 300 provides 5.5kWh of capacity, significantly more than the 4096Wh in the original. It weighs 83.8 pounds, making it 31.2 pounds lighter than the reference unit. Its dimensions are 12.9 inches wide and 12.6 inches high. The data mentions a 700W extended battery life kit but does not specify included solar panel wattage. It supports dual-voltage output for heavy appliance backup. You gain nearly 1.4kWh more storage and much better portability. Opt for this if you need maximum run time for off-grid use without moving a heavy tower.
Solstark OUKITEL P2001 Pro 2048Wh
The Solstark OUKITEL P2001 Pro has 2048Wh of capacity, which is half the energy of the original 4096Wh unit. It weighs 50 pounds, a substantial 65-pound reduction. The dimensions are 11.3 inches wide and 12.9 inches high. It includes 400W of solar charging capability. This model focuses on fast charging and app control rather than maximum duration. You sacrifice total backup time for significantly easier handling and transport. Pick this if you need a mid-range option for camping or short outages where carrying heavy weight is a primary concern.
EF EcoFlow DELTA 3 Classic 1024Wh Power Station
The DELTA 3 Classic contains 1024Wh of capacity, which is much lower than the 4096Wh in the reference unit. It weighs 21.9 pounds, making it extremely portable compared to the original. The dimensions are 11.1 inches wide and 15.7 inches high. It includes a 400W solar panel for charging. This unit is designed for fast recharging and short-term backup. You lose significant runtime for appliances but gain a lightweight, compact form factor. Choose this if you only need power for phones, laptops, or lights during brief power interruptions.
Anker SOLIX C1000 Gen 2 with 400W Solar Panel
The Anker SOLIX C1000 Gen 2 offers 1,024Wh of capacity, far less than the 4096Wh in the original. It weighs only 21.9 pounds, which is 93.1 pounds lighter. The dimensions are 11.2 inches wide and 17.6 inches high. It includes a 400W solar panel for charging. This model prioritizes fast recharging speeds and portability over raw energy storage. You get a unit that is easy to carry on trips but cannot run high-wattage home appliances for long. Select this if you need a lightweight backup for travel or day trips rather than whole-home power.
