Start with the load, then compare portability
These models sit in the compact portable-power class, so the decision is usually a trade-off between stored energy, inverter headroom, charging, weight and the appliances you actually intend to run.
BLUETTI AC70
- Capacity: 768Wh
- AC output: 1,000W total
- AC input: 950W max
- Solar input: 500W max
Jackery Explorer 600 v2
- Capacity: 640Wh
- AC output: 500W / 1,000W surge
- Cycle life: 6,000+ cycles
- UPS switching: ≤0.01 second
Runtime and power are different questions
Capacity estimates how long a load may run. AC output determines whether the station can start and sustain that load. Motor/compressor surge and conversion losses must be considered separately.
Use manufacturer-specific charging limits
Solar input limits, supported voltage windows and charging accessories are model-specific. Do not size a solar panel array from the power-station name alone.
