DC output stores the regional Jackery 12V/10A car-port listing for the same 240 v2 model family.
Regional source note: Some specs are cross-checked against official regional pages (uk.jackery.com: Jackery Explorer 240 v2 UK specifications). Regional SKUs can differ; verify the manufacturer page for your market before purchase or emergency planning.
Runtime Starting Points
These are formula estimates using the tracked capacity, a 10% reserve, and each scenario's default wattage and duty cycle. They are planning starters, not measured runtimes.

Good fit when
- Capacity is a compact class; use it for small electronics and short essentials rather than high-wattage appliances.
- Tracked AC output is 300 W, so high-draw appliances and tools need careful filtering.
- USB-C output is tracked at laptop-class power, useful for direct DC charging when the device supports it.
- Tracked solar input is 100 W before panel, weather, angle, and controller losses.
Watch out for
- Surge output is tracked, but device startup behavior should still be checked against the actual load.
