FAQ
Can I plug this straight into my vehicle’s cigarette lighter?
No—you must connect using the supplied heavy-duty ring terminals and inline fuse (100 A) to avoid overheating and ensure full current capability.
Will it hurt my car battery if engine is off?
No—as long as you turn the switch off when the engine is not running. Once the engine starts and voltage rises, the charger automatically begins outputting power.
What devices can I charge?
Any power station or battery bank with a solar input rated up to 42 V, such as Pecron E-series, Bluetti, EcoFlow Delta, Jackery Explorer, and similar systems .
How do I adjust the starting voltage?
Use the dial (gear 0–5) to set the voltage threshold—checker in the instruction manual shows exact volts for each gear position .
