Wagan Lithium Cube EX18 Power Station
Description
The Wagan Lithium Cube EX18 is a next-generation portable power station built around a long-lasting LiFePO4 battery with 1440Wh of capacity and 1800W of continuous pure sine wave AC output. Designed for overlanders, campers, RV travelers, jobsite workers, and home backup users alike, the EX18 delivers serious power in a surprisingly compact, upright form factor that takes up minimal floor space. Its built-in UPS (Uninterruptible Power Supply) function with a switching time of 10ms or less keeps sensitive devices like computers and CPAP machines running without interruption during power outages - no complicated wiring required.
Fast-charging via the included AC adapter takes the EX18 from 0% to 100% in approximately 1.5 hours, and up to 600W of solar input via the MPPT charge controller keeps you off-grid and fully powered. Two units can even be paralleled together to double both the output and the battery capacity, making the EX18 one of the most scalable portable power solutions available today.
Key Features
- LiFePO4 Battery - 48V / 1440Wh: Lithium-iron phosphate chemistry delivers more lifecycles, longer lifespan, deeper discharge capability, and fast-charge compatibility compared to standard lithium-ion cells.
- 1800W Continuous / 3600W Peak Pure Sine Wave Inverter: Powers sensitive electronics, appliances, tools, and lighting cleanly and safely across 4 standard 120V AC outlets.
- UPS Function - 10ms Switching Time: Plug the EX18 into the wall and use it as an uninterruptible power supply - if grid power fails, your plugged-in devices keep running with no noticeable interruption.
- Fast Charging - 0 to 100% in ~1.5 Hours: The included 1000W AC fast-charger gets you back to full power faster than virtually any comparable unit on the market.
- 600W Solar Input via MPPT Controller: Universal Anderson Powerpole connector supports up to 600W of solar panels; MPPT technology maximizes efficiency and minimizes energy loss.
- Parallel Capability - Up to 3600W / 2880Wh Combined: Connect two EX18 units with the optional paralleling cable (sold separately) to double both the output wattage and total battery capacity.
- Pass-Through Charging: Keep the EX18 plugged in and continue using all its output ports simultaneously - ideal for home backup and continuous-use scenarios.
- 6 USB Ports (including 2x USB-C PD 100W): Two USB-C Power Delivery ports at 100W each, two fast-charge USB-A ports at 60W, and two standard USB-A ports at 12W cover all your device charging needs.
- Marine-Grade Twist-Lock 12V DC Socket: Upgraded twist-lock design keeps 12V plugs secure over rough terrain - perfect for overlanding, off-roading, and running fridges without the timeout function.
- Comprehensive Safety Certifications: UL-certified battery, plus over-voltage, over-charge, short circuit, reverse polarity, and overload protection for worry-free operation.
- Compact Upright Design - 39.2 lbs.: Tall and slender (15.6 x 9 x 11.5 in.) to maximize vertical space while minimizing floor space in vehicles, campers, and storage areas.
- 2-Year USA Warranty: Backed by Wagan's full manufacturer warranty for domestic buyers.
Options & Which to Choose
- Lithium Cube EX18 (Unit Only): The power station by itself - the best choice if you already own compatible solar panels or plan to charge primarily via AC or DC. Ideal for home backup, jobsite use, or buyers building a custom solar setup.
- EX18 + 100W Solar Panel: Pairs the EX18 with a 100W Sunpower folding solar panel (23% efficiency, 6.6 lbs.). A great starter solar bundle for camping and weekend off-grid use where you want some solar capability without added bulk or weight.
- EX18 + 200W Solar Panel: Pairs the EX18 with a 200W monocrystalline ETFE panel (23% efficiency, 12.5 lbs.) for significantly faster solar recharging. Best for extended off-grid trips, overlanding, or cabin use where maximizing solar harvest matters most.

Why You'll Love It
The Wagan Lithium Cube EX18 is built for people who need real, reliable power - not a glorified battery bank. Whether you're keeping the lights on during a blackout, running power tools on a remote jobsite, or powering your overlanding rig deep in the backcountry, the EX18 performs without compromise. The LiFePO4 chemistry means this unit will outlast and outperform conventional lithium-ion power stations, giving you more charge cycles and more confidence over the long haul. The 1.5-hour fast charge is a genuine game-changer for anyone who's ever waited half a day for a power station to recover.
Wagan has been a trusted name in portable power for decades, and the EX18 represents the best of their engineering - thoughtful features like the marine twist-lock 12V socket, removable timeout function, and true UPS capability show that this unit was designed by people who actually use portable power in the field. If you need a scalable, future-proof power station that can grow with your needs (just add a second unit and a paralleling cable), the EX18 is the one to buy.

FAQ
What is the difference between the EX18 and a regular portable power station?
The EX18 uses LiFePO4 (lithium-iron phosphate) chemistry rather than standard lithium-ion, which means significantly more charge cycles, a longer overall lifespan, and the ability to discharge more deeply without damaging the battery. It also includes a true UPS (Uninterruptible Power Supply) function with a 10ms switching time - something most consumer power stations don't offer - along with fast charging, pass-through charging, and parallel capability to double its output and capacity.
How long does it take to fully charge the EX18?
Using the included 1000W AC fast-charger, the EX18 goes from 0% to 100% in approximately 1.5 hours. You can also recharge via solar panels (up to 600W input), a 12V DC vehicle outlet, wind turbine, or hydro-electric source. Recharge times for solar will vary depending on sunlight conditions and panel wattage.
Can I use the EX18 while it is plugged in (pass-through charging)?
Yes. The EX18 supports pass-through charging, which means you can keep it plugged into wall power and use all of its output ports at the same time. This is ideal for home backup scenarios where you want the unit always ready while simultaneously powering devices.
What does the UPS function do and how does it work?
The UPS (Uninterruptible Power Supply) function allows you to plug the EX18 into a standard wall outlet and then plug sensitive devices - like a computer, CPAP machine, or NAS drive - into the EX18's AC outlets. If the grid power goes out, the EX18 switches to battery power in 10ms or less, which is fast enough that most devices won't even notice the interruption. No special wiring or configuration is needed.
Can I connect two EX18 units together for more power?
Yes. The EX18 supports parallel operation. With the optional paralleling cable (sold separately), two EX18 units can be combined to double the continuous output from 1800W to 3600W and double the battery capacity from 1440Wh to 2880Wh. This makes the EX18 a highly scalable solution for demanding applications.
What solar panels are compatible with the EX18?
The EX18 accepts up to 600W of solar input through its built-in Anderson Powerpole connector, which is a universal standard that works with a wide range of solar panels. The MPPT solar charge controller accepts an input voltage range of 11-70V DC. Wagan's own 100W and 200W folding solar panels are available as bundle options and are confirmed compatible.
Is the EX18 safe to use indoors?
Yes. Unlike gas-powered generators, the EX18 produces no fumes, carbon monoxide, or exhaust, making it completely safe for indoor use. The UL-certified LiFePO4 battery and built-in protections (over-voltage, over-charge, short circuit, reverse polarity, overload) make it one of the safest portable power options available. Always follow the manufacturer's guidelines for operating temperature and ventilation around the unit.
