Very fast response, it's a pity that the shipment cannot be sent somewhere to a delivery point or a delivery box. The customer is not always at home.

I bought this product because new cars that have start-stop have a big difference in the mains voltage during operation. I have a computer in my car. freezer both 12 volts and 220 volts. The voltage monitor in the car network turned off the refrigerator while driving when the voltage dropped. But this inverter only switches off when it drops below 11 volts. The refrigerator has an operating consumption of up to 100 W. So it's more than enough for that. There is still a reserve for charging the power bank. Good for me.
