The 5 Critical Differences That Actually Matter

1. Charging Speed: The Battle of Fast-Charging Technologies

Both brands now compete intensely with revolutionary charging technologies that fundamentally change how you use portable power.

EcoFlow’s X-Stream Advantage: The Delta 2 charges from 0-80% in just 50 minutes using standard AC wall power, with full charge in 80 minutes. The flagship Delta 3 achieves full charge in 56 minutes by combining solar and AC input simultaneously—revolutionary performance that eliminates the overnight charging requirement of traditional generators.

Anker’s HyperFlash Technology: The Solix C1000 Gen 2 achieves even faster performance with 0-80% in approximately 39 minutes and full charge in just 49 minutes at 1,600W—the fastest mid-range charging available in 2025. This represents a significant leap over previous generation portable power stations.

Real-World Impact: During our power outage testing, Anker’s revolutionary 49-minute full charge meant we could completely recharge during brief power restoration windows.

When grid power returned at 1 PM and failed again at 2 PM, the Anker C1000 achieved 100% capacity. The EcoFlow Delta 2 reached approximately 75% in the same timeframe—still excellent, but Anker’s speed advantage proved decisive for rapid cycling scenarios.

For RV travelers, both brands’ ultra-fast charging transforms power management. An hour at a restaurant with AC outlets provides full charge on Anker or near-complete charge on EcoFlow—eliminating the traditional overnight charging requirement that limited mobility.

Solar Charging: Anker edges ahead with 600W max solar input on the C1000 (1.8-hour full charge) versus EcoFlow’s 500W on the Delta 2 (~2 hours).

The premium Anker F3800 accepts up to 3,200W solar input versus EcoFlow Delta 3’s 600W—over 5x advantage for serious off-grid solar charging. Both brands use standard MC4 connectors, allowing any third-party solar panels.

2. Portability: Anker’s Weight Advantage

Anker’s engineering philosophy prioritizes true portability, resulting in consistently lighter units across every capacity class.

Weight Comparison (1000Wh Class):

– EcoFlow Delta 2: 27 lbs
– Anker Solix C1000: 24.9 lbs
– Difference: 2.1 lbs (8% lighter)

Weight Comparison (Premium Class):

– EcoFlow Delta 3: 27.5 lbs
– Anker F3800: 135.6 lbs
– Difference: 108.1 lbs (but F3800 has 3.75x more capacity)

These weight differences translate to noticeable handling advantages for camping, emergency evacuation, and frequent relocation scenarios.

Anker’s lighter construction doesn’t compromise build quality—they achieve weight reduction through optimized internal layouts and efficient component selection rather than cheaper materials.

Bottom Line: If you’re frequently carrying your power station between vehicle and campsite, up stairs during power outages, or loading/unloading from RVs, Anker’s consistent weight advantage matters significantly.

For stationary installations (workshops, home backup closets, permanent RV setups), choose based on features rather than portability.

3. Expandability: Modular Power Systems

Both brands now offer expandable capacity, but they approach scaling differently.
