The E500 Pro Jacker Explorer Power Station provides 500W of continuous power, which can handle short surges up to 1000W, for those surge appliances such as a small esky refrigerator/freezer. It has a front AC outlets with a pure sine wave perfect for long-term care of sensitive devices such as computers and other electronics. It has a DC input for charging with a solar panel, or for charging from a vehicle‘s 12V outlet with the adapter. Alternatively, the wall charger can also charge the unit from the same port. It also provides 3x USB slots, a 12V 10A socket outlet with 2 more 12V plug outlets, and a side torch light. Features a compact, modern, lightweight, sleek design with an informative display for ease of reading capacity and charging status. Jackery Australia appears to have recently stepped up their customer support and service in Australia for Jackery units. While this unit can retain battery charge for some time when sitting unused, I would personally recommend to mark your calendars to remember to charge the unit 3 times per year if sitting unused. It is very easy to do, and will help to preserve the longevity of the unit even beyond warranty.
