This large 500W Mobile power station is just what you need for those long dark nights whether in the garden or off the beaten track at a dark sky location. With the various connection options, you can operate and charge almost all common electronic devices via the powerful and rechargeable 520Wh lithium-ion battery. Perfect for Telescope Mounts, Dew heaters, Laptops etc. In addition, this mobile power station is a silent and an environmentally friendly alternative to running the car engine or using small conventional power generators. In combination with a suitable solar panel, the built-in solar charge controller allows you to easily use the sunshine to directly charge your Power Station to keep it topped up during the day.

Connection options:
You can charge up to 4 x USB mobile devices such as Smartphones, MP4 players, Cameras, Drones etc. and all at the same time. The device offers 1 x USB-A and 1 x USB-C fast charging output with Qualcomm Quick Charge 3.0 support. You can also power up to 5 x 12 volt devices with a total of 10 amps of current draw. Use 1 direct car cigarette lighter connector socket and 4 x DC 2.1/5.5mm connector sockets.

The built-in battery:
The powerful 520Wh 43Ah/12Volt (140400mA/3.7V) lithium-ion battery reliably stores your enough power in just one charge to operate multiple telescopes at once for many nights out in the open or for a single setup for even longer. It takes around 8 hours to charge from zero and a clear display shows you all relevant information such as the battery charge status, battery charging process, USB output ON/OFF and AC/DC output ON/OFF.

Possible operating time with typical applications:
How long does the Power Station charge or operate your devices? You can easily calculate the approximate operating time yourself with this very simple formula. Runtime (approx.) = Power Station 520 watt-hour battery x 0.85 / devices input power in watts. - For example a notebook with 45 Watt input power: 520 W/h x 0.85 / 45 Watt = runtime in hours; 520 x 0.85 / 45 = 10 hours runtime.

Extensive electronic protection of all current inputs and outputs:
The Power Station is protected against short circuit, overvoltage, over- and deep discharge of the battery and against overheating.

Please note that for use with Astronomy mounts, such as the EXOS-2 Goto, a cigarette lighter adapter is additionally required - These are normally supplied with your mount but can be purchased separately.
