Full power guaranteed

More power with the portable power storage unit from GRANIT



The portable power storage unit based on lithium-ion battery technology scores points thanks to its high battery capacity, plus its small size and low weight (despite the integrated high-performance converter). This makes it easy to transport the GRANIT battery. Thanks to the robust housing, it can be used for both indoor and outdoor applications, giving you maximum flexibility when it comes to your construction site power supply.


The lithium-ion battery can be used simultaneously with an AC output of 110 V / 220 V and a DC output for 5 V / 12 V, which makes it suitable for most electrical consumers. The high capacity, long service life and high efficiency also make the GRANIT power storage unit an extremely reliable tool. Equipped with SPWM (sinusoidal pulse width modulation) technology, the battery enables high-precision voltage output with low voltage deviation. The overcharge protection and discharge protection function also protect the battery from damage. And with the low battery warning function, you'll never unexpectedly run out of juice again.
