This unit is engineered for both home backup and portable use, giving you stable performance across different environments.
Battery & Specs
Equipped with a 1440Wh LiFePO4 battery, this generator provides:
- Longer cycle life (up to 3000+ cycles)
- Improved safety
- Consistent voltage output
You can expect 10–12 hours powering a mini-fridge or charge a laptop over 20 times. For heavier loads, the runtime will vary — but it’s impressive for a generator under 50 lbs.
Better yet, the battery is expandable with additional Nature’s Generator Power Pods for extended runtime.
Portability & Design
At 47 pounds, this unit is on the heavier side for quick carry, but it’s manageable thanks to built-in wheels and a telescoping handle. The design features:
- A durable metal and plastic hybrid case
- Front-facing ports for easy access
- LCD screen that shows battery percentage, wattage in/out, and error codes
It’s clearly made with mobility in mind, whether you’re moving around a job site or your backyard.
Charging Options
The Nature’s Generator Lithium 1800 gives you three ways to recharge:
- AC wall outlet (~8 hours)
- Solar panel (~6–10 hours with 300W solar input)
- Wind turbine (compatible with Nature’s Generator Wind Turbine)
This flexibility makes it suitable for off-grid cabins, RVers, or anyone preparing for power outages.
Note: Solar panels and wind turbine are sold separately.
Price & Value
At around $999–$1,199, the Nature’s Generator Lithium 1800 is competitively priced for its capacity and feature set.

FAQs
How long does the Nature’s Generator Lithium 1800 last on a full charge?
It depends on your load. A 100W device could run for around 12–14 hours. Heavier loads like fridges or power tools will shorten runtime.
Can I use this while charging it with solar?
Yes, the unit supports pass-through charging, meaning you can power devices while recharging via solar, AC, or wind.
Is it waterproof or weather-resistant?
No, the generator should be kept dry and protected from rain or extreme conditions. Use in sheltered locations when outdoors.
