Dakota Lithium Powerbox+ 135 Waterproof Solar Generator
Power Anywhere. Float Anywhere. Start Anything.
The Dakota Lithium Powerbox+ 135 Waterproof Solar Generator is built for people who refuse to stop when conditions get extreme. Designed to operate in rain, snow, freezing temperatures, and open water, this fully submersible lithium power station delivers uncompromising performance where traditional generators fail.
Powered by Dakota Lithium’s legendary DL+ 12V 135Ah dual-purpose battery, the Dakota Lithium Powerbox+ 135 Waterproof Solar Generator provides engine-starting power, deep-cycle energy, and modern AC and USB output in one rugged, floating system trusted by professionals, anglers, and off-grid adventurers.
Features
Dual-purpose lithium performance combines 135Ah of deep-cycle capacity with 1,000 Cold Cranking Amps, allowing the system to start engines while also running electronics, motors, and appliances.
A military-grade IP67 waterproof and fully submersible case is designed to float, resist shock, and operate reliably in harsh marine, overland, and expedition environments.
A built-in 2,000W pure sine wave inverter delivers household-grade AC power along with USB-C PD 60W fast charging and external waterproof USB ports for phones, laptops, cameras, tools, and portable refrigerators.
High-power waterproof binder posts support trolling motors, sonar systems, electric coolers, and other demanding 12V applications.
Internal even-heat battery technology enables reliable cold-weather operation down to -20°F, ensuring consistent performance in winter conditions.
A field-serviceable internal layout allows easy access, maintenance, and long-term expedition readiness.
Lithium iron phosphate chemistry provides twice the usable power, half the weight, and up to four times the lifespan of traditional lead-acid batteries.
An industry-leading 11-year warranty delivers unmatched long-term value and peace of mind.
Benefits
