3000w Power Inverter With 30A Battery Charger (2in1)

INVERTERDC 5V USB output3000W DC 12V to AC 230VLow standby power costMultiple safe protectionUniversal output socketIntelligent cooling fan controlled by the workloadThis power inverter is extraordinarily designed for home use,which can convert DC 12V/V of portable power supply to AC V and it works for almost all the household electrical resistive appliances such as MP3/MP4 player,cell phone, laptop, emergency light, electric blanket, electric shaver, electric cooker,digital camera, digital video,CD/DVD player,XBOX/PS4 game player, ordinary electric lamps, bulb,fluoresent light, rice cooker,electric iron,desktop computer, graphoscope,fax machines, printers, LCD TV, electric fans, cell phone chargers, electric iron , drinking fountain,hair dryer and so on.(Note:Only pure sine wave inverter can run sensitive electric appliances that are including refrigerator, washing machine,microwave oven, induction cooker, electric drill,compressor,air conditioner,mercury lamp, sodium lamp and so on). 
CHARGER
The lead-acid battery charger is professional design according to the power battery of electric vehicles equipment. It uses the advanced soft switch technology, with small size, high conversion efficiency, running full loading for a long time, stable output current, high reliability, long service life, easy operation,etc. With short-circuited protection, low-voltage protection, over-heated protection. The long delay digital counter can ensure the battery from the constant voltage to the float charge reliably every time.
 
Pre-charge mode: In order to protect the battery and extend its life, the battery’s internal resistance is too large or voltage is too low because the discharged time is too long or it is not used for a long time, the charger will supply low output current for the battery automatically. When voltage of the battery rises to the given voltage value, the charge mode will turn to constant current charge mode automatically.Constant current mode: The charger supply constant charge current for the battery.Constant voltage mode: Using the pulse width modulation(PWM) tech to control the charging current and output voltage of the charger which ensure the battery is fully charged and avoids over charging.Floating charge mode: When the voltage of the battery is approaching the value of the constant voltage mode, and the current cut down to the given current gradually, that means the battery power is full, then the pilot lamp will turn green and the fan will stop working.The charger will turn the mode into floating charge mode automatically. At this moment, the battery can be stopped charging or keep on floating charge for half an hou
