How the Alternatives Compare
EF EcoFlow Delta 3 with 220W Panel
This version keeps the same 1024Wh capacity and 1800W output but upgrades the solar setup to a 220W bifacial panel. Bifacial panels capture light from both sides, potentially increasing energy harvest compared to the standard rigid panels on the Delta 3. The dimensions and weight remain identical at 46 pounds. You gain higher solar efficiency without changing the footprint. Choose this if you want faster solar charging in varied light conditions while keeping the familiar EcoFlow ecosystem and expandability features.
ALLPOWERS P1800 1024Wh Outdoor Power
The ALLPOWERS P1800 matches the 1024Wh capacity and 1800W output but uses a larger chassis measuring 10.4 by 16.3 inches. It includes USB-C output ports and supports UPS backup functions for seamless power switching. The battery chemistry is also LiFePO4, ensuring similar cycle life. You trade the compact EcoFlow design for dedicated UPS reliability and modern USB-C connectivity. Pick this model if you need uninterrupted power for sensitive electronics and prefer a simpler, budget-friendly option with similar core specs.
BLUETTI Elite 100 V2 with 100W Solar Panel
The BLUETTI Elite 100 V2 offers the same 1024Wh capacity and 1800W output in a significantly lighter 25-pound frame. Its dimensions are smaller at 8.5 by 12.6 inches, making it easier to carry. It includes a 100W solar panel for charging. You lose some brand-specific ecosystem features but gain substantial portability. This model suits users who prioritize lightweight design and quiet operation for camping or short-term backups over the heavier, more robust Delta 3 chassis.
BLUETTI 1152Wh Solar Generator with 200W Panel
The BLUETTI AC180 provides 1152Wh of capacity, which is slightly higher than the Delta 3, while maintaining the 1800W output. It weighs 37.4 pounds, making it lighter than the 46-pound Delta 3. The unit measures 9.7 by 13.4 inches and includes a 200W solar panel. You get more stored energy and a lower weight for similar power delivery. Choose this alternative if you need extra runtime for home backups and prefer a lighter unit with comparable solar charging capabilities.
BLUETTI FridgePower 2016Wh Slim Power Station
The BLUETTI FridgePower features a massive 2016Wh capacity, nearly double that of the Delta 3, while keeping the 1800W output. Its slim profile is only 2.95 inches wide, designed for tight spaces. It weighs 41.9 pounds and offers 10ms UPS switching. You sacrifice portability and general-purpose flexibility for dedicated refrigerator backup and extended runtime. This model is ideal for homeowners who need long-duration power for appliances in space-constrained areas rather than a versatile portable station.
EBL 2400W Power Station with Two 200W Solar Panels
The EBL unit delivers 2400W of output, significantly higher than the Delta 3, with a compact 6 by 9-inch footprint. It includes two 200W solar panels for robust solar input. The design is smaller in height and length but lacks modern smart connectivity features. You gain higher continuous wattage and more solar power for off-grid setups. Select this model if you need raw power for RV boondocking or high-demand appliances and do not require app-based monitoring or smart controls.
