Frequently Asked Questions
What devices can it power?
Suitable for fans, lights, TVs, laptops, and small electric tools.
What capacity battery can be used with it?
It is recommended to use a 12V 100Ah-200Ah lead-acid battery or lithium battery; the larger the battery capacity, the longer the UPS power supply time (e.g., a 100Ah battery can support a 100W device to work continuously for about 10 hours).
Can it be used in RVs or trucks?
Yes. The device input voltage is DC 12V, which matches the battery voltage of RVs and trucks. It can be connected via battery clips or cigarette lighter interface (need to confirm that the maximum current of the cigarette lighter is ≥10A) to supply power to car refrigerators, parking air conditioners, laptops, etc.
Can it drive a 3000W air conditioner?
Yes. Air conditioners have instantaneous power during startup (about 2-3 times the rated power), and this product has a peak power of 6000W, which can meet the startup and operation needs of a 3000W air conditioner; the battery capacity must be ≥150Ah to ensure continuous power supply.
