Built-in lithium battery
The Alrska Portable Power Station 300 has a built-in lithium battery, the battery is typically rated for 500 full charge cycles and/or 2-3 years. At that point, you'll have about 80% of the original battery capacity and taper off from there. It is recommended to use and recharge at least every 3 months to maximize the life of the power station.
Alrska Element 300 uses high-quality MPPT technology and built-in MPPT solar charge controller. And it uses an off-grid solar power generation system, which is a clean energy source that is different from ordinary generators.Alrska Element 300 uses 100W GreenSun solar panels and can be quickly charged using solar energy within 5.5 hours

PREPARING YOUR SOLAR GENERATOR
OFF-GRID SOLAR GENERATOR, GREEN AND CLEAN POWER SUPPLY
With the MPPT solar charge controller inside, the Element 300 can be charged more efficiently. When paired with a compatible solar panel like the Alrska GreenSun 100W (sold separately), it can perform as a solar generator. Under full sun, the GreenSun 100W can charge the Element 300 in just 3.5 hours from 0-80%. (Shop Solar Generator 300)
Please note that the AC output port can only charge/power devices that operate at less than 300-Watt. Besides, the whole wattage should be under 300 watts as well . Once exceeding, the Explorer 300 will shut off automatically. Please refer to your device specification before purchase
A: Working time = 330Wh* 0.85 / operating wattage of your device
For reference, assuming power consumption of your device is 30W (might be a box fan), working time will be 330Wh*0.85/30w=9.35hrs (rough calculated) .
Please note: actual power consumption varies from different usages, please consult Jackery for better purchase decision.
Yes, you can use the Element 300 to charge other things, while it's being recharged at the same time
