FAQ
What capacity battery is needed to meet long-term use?
It needs to be calculated according to the total power of the device, the formula is "Battery Capacity (Ah) = Total Device Power (W) × Usage Time (h) ÷ Input Voltage (12V)". For example, to drive a 1000W device for 5 hours, the required battery capacity = 1000×5÷12≈417Ah, it is recommended to use 2 200Ah batteries in parallel (total capacity 400Ah, actual usage about 4.8 hours).
How many devices can it power at the same time?
Dual universal sockets + two USB ports can power multiple devices (such as two home appliances + two mobile phones) at the same time, as long as the total power does not exceed 600W.
Can I order samples before production?
Yes, we offer sample evaluation and prototype testing.
What devices can this inverter support?
It can power laptops, phones, cameras, and other small appliances.
