Ready-to-use power kit

This Kastar PS-42B pack supplies one foldable AC wall charger and four lithium-ion batteries built for the SteelSeries Arctis Nova Pro Wireless headset family. Each cell delivers 3.7 V and 1400 mAh for 5.18 Wh of capacity. The bundle covers the standard, Xbox and PlayStation editions of the headset. Gamers who need a spare set for long sessions can swap cells without hunting for a proprietary dock.

Cool, quiet wall charging

The charger accepts 100 to 240 V at 50 or 60 Hz and outputs a steady 4.2 V at 600 mA. With no fan inside, the unit runs silently on a desk or nightstand. A red LED shows active charging and a green LED signals standby or a full cell. The foldable flat pins tuck away, reducing the risk of bent prongs during transport.

Simple swap, no extra gear

Each battery slides into the headset’s existing compartment, so no tools or adapters are required. The single charger tops up one cell at a time, freeing the headset’s USB port for audio use while a spare charges. Buyers who want simultaneous multi-cell charging or a dedicated dock will need a different solution.

Questions about this item

How do I install the four batteries and charger, and what step do people often miss?

Insert each 1400mAh 3.7V Li-Ion cell into the Arctis Nova Pro Wireless headset battery slot, then plug the charger into a 100-240V AC outlet; the step often missed is waiting for the green LED before first use.

What maintenance or replacement will the pack need over time?

The four 5.18 Wh lithium-ion batteries will gradually lose capacity; expect to replace the full set when charge runtime drops below your session needs.

What limit appears first during continuous charging cycles?

The charger’s 600mA 4.2V DC output sets the recharge rate, so sustained back-to-back cycles are limited by that fixed current.
