Whether you're preparing for unexpected outages, traveling in an RV, camping off the beaten path, or powering tools at a remote job site, the Lithium Cube EX18 provides convenient AC and DC power along with multiple USB charging options in a single portable unit. Built around a long-lasting LiFePO4 battery and a pure sine wave inverter, it delivers clean power for a wide range of everyday electronics and appliances while offering flexible charging from AC power, a vehicle, or compatible solar panels.
The Lithium Cube EX18 combines substantial battery capacity, multiple output options, and fast recharging into a portable backup power solution. Its comprehensive LCD display helps you monitor battery status, charging, power input, power output, and estimated remaining runtime, making it easier to manage your available energy wherever you are.
The built-in pure sine wave inverter provides up to 1,800 watts of continuous AC power with a 3,000-watt peak output. Pure sine wave output closely resembles household electricity, making it suitable for powering many everyday appliances and electronic devices that benefit from clean, stable power.
The Lithium Cube EX18 offers a variety of connection options to support different types of equipment.
This variety makes it easy to charge phones, tablets, laptops, communication devices, and many other compatible electronics from a single portable power source.
The unit supports several charging methods to help keep you powered wherever you are. It can be recharged from a standard AC outlet, a compatible 12V or 24V vehicle outlet, or compatible solar panels connected through the DC7909 input. The built-in MPPT solar controller supports up to 400 watts of solar input, and the manual notes approximately:
Actual charging times may vary depending on conditions.
The integrated LCD display provides useful operating information including battery percentage, charging and discharge estimates, input and output power, charging status, and system notifications. An integrated LED light offers low, medium, high, and SOS lighting modes for added convenience around camp, during emergencies, or while working after dark.
The Wagan Lithium Cube™ EX18 is designed for a variety of practical situations, including:
The user manual specifically describes applications including emergency home use, job sites without power lines, camping, lighting, communication equipment, entertainment devices, and selected appliances.
Compared with a traditional gas generator, the Lithium Cube EX18 operates without gasoline and provides pure sine wave AC output. Unlike many lead-acid battery power solutions, it uses a LiFePO4 battery rated for more than 3,000 cycles to 80% remaining capacity under the manufacturer's stated test conditions. It also combines AC outlets, USB charging, DC outputs, and multiple charging methods into one portable system.
Customers should remember that portable power stations are designed for selected loads rather than powering an entire home continuously. Before connecting equipment, always verify that the appliance's power requirements remain within the unit's rated output.
The Wagan Lithium Cube™ EX18 may be an excellent fit if you want a portable backup power solution with multiple charging options and a broad selection of output ports.
