Question you may concern
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).
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 capacity battery is needed to drive a 1000W electric kettle?
It is recommended to match with a 12V 100Ah or larger capacity battery. When a 1000W electric kettle is working, the power consumption per hour is about 83Ah (1000W÷12V≈83A), and a 100Ah battery can support continuous work for about 1 hour (actual battery life is affected by battery aging).
Which types of batteries can it be used with?
It is suitable for common DC batteries such as 12V lead-acid batteries and lithium batteries. Please ensure the battery voltage matches the inverter's input voltage before use.
3000W Full-Power Pure Sine Wave Inverter, DC 12V to AC 220V Power Converter, Suitable for High-Power Precision Devices
This 3000W full-power pure sine wave inverter (Model: CS3000PSW) adopts pure sine wave output technology (waveform distortion rate <2%), and the output power is highly consistent with mains power quality. It can safely drive high-power precision loads such as air conditioners, refrigerators, medical instruments, and small industrial equipment, avoiding equipment malfunctions or shortened service life caused by unstable waveforms. The device supports DC 12V input (compatible with 10.5V-14.8V wide voltage), continuously outputs 3000W full power, and has a peak power of 6000W, easily coping with the instantaneous startup impact of high-power devices; it is equipped with 4 AC universal sockets (max current 16A) + 2 USB 3.0 fast-charging ports (22.5W per port) to meet the simultaneous power supply needs of multiple devices. Built-in six-fold safety protection (overload, overvoltage, undervoltage, short circuit, overtemperature, reverse connection), combined with dual intelligent silent cooling fans (noise ≤45dB), it achieves the triple advantages of "high power + high safety + low noise," suitable for home emergency, outdoor engineering, vehicle-mounted power supply, small industrial scenarios and other fields.
