KOSUNPOWER UPS backup power supply with external battery 300W battery 12V AC230V pure sine

KOSUNPOWER KOS300-12 300 W

Pure sine wave voltage converter, has an integrated charger and a USB output (with a voltage of 5 V, a current of 2.1 A) for charging various devices. The device also has a UPS function (automatic switching of the mains and battery in the event of a power failure). Modern and beautiful design, quality workmanship, impact resistance and reliability of operation, these are the characteristic features of this product.

Compared to competing backup sources, it stands out with its fractional own energy consumption - consumption 4-6W measured in laboratory conditions, which significantly increases efficiency and reduces battery requirements for long-term backups. Compared to the commonly measured consumption values of comparable products, this is a saving of up to 80% of energy.

This is a device intended for the supply of alternating current in places where there is no permanent source of mains power. The inverter is intended for use especially in the wild, in a cottage or cottage, on a boat, in a caravan, in a truck, when traveling, etc. Thanks to the pure sinusoid at the output, it is possible to use it for various electrical appliances with regard to the required power (W). Integrated 3-stage charger is designed for charging lead-acid (WET-flooded), maintenance and maintenance-free, gel, AGM, EFB batteries.

ATTENTION, the charger is not intended for charging Li-ion batteries (LiFePO4, etc.)
