FAQ:
What’s the main difference between your OEM and ODM services?

OEM uses your brand on our standard products; ODM creates entirely new products based on your concept or specification.

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).

Will reversing the positive and negative poles damage the device when connecting the battery?

The device has a built-in reverse connection protection function, which will automatically cut off the circuit when the positive and negative poles are reversed to avoid damage caused by reverse current inflow; just adjust the connection order of the positive and negative poles of the battery clip and re-power on to use normally.

What is the function of the independent control switch?

The independent control switches for DC and AC can respectively control the on and off of DC and AC circuits, facilitating the separate management of power supply for different types of devices and improving power usage safety and flexibility.

Is it a pure sine wave or a modified sine wave? What's the difference?

This is a modified sine wave inverter, suitable for most conventional home appliances and electronic devices; pure sine wave is suitable for precision devices with extremely high power requirements. This modified sine wave is more cost-effective at 2000W, meeting the needs of most scenarios.
