Kastar NP-BX1 Kit for Sony Cyber-shot Cameras

This kit supplies two lithium-ion NP-BX1 batteries and a triple USB charger for owners of Sony Cyber-shot RX100 VI, RX100 VII, WX300, WX350 and many other listed models. Each cell delivers 3.7 V and 1240 mAh for 4.6 Wh capacity. The charger accepts 5 V 2 A input and can replenish three packs simultaneously. A micro USB cable is included for connection to wall adapters, car chargers or computers.

Replaces OEM Sony NP-BX1 Cells and BC-CSX Chargers

The two 1240 mAh packs substitute for Sony NP-BX1, Type X and X-Series batteries used across the RX100 series, HX compacts and action cams. The LCD charger replaces Sony BC-CSX, BC-CSXB, BC-TRX and ACC-TRBX units while adding three-bay simultaneous charging. The upgrade is worthwhile when a single-bay charger creates a bottleneck during multi-day shoots or travel.

Micro USB Power and LCD Status Simplify Setup

Plug the charger into any 5 V 2 A USB source using the supplied micro USB cable; no proprietary wall wart is required. The intelligent LCD shows real-time charging status and remaining capacity for each bay. The main friction point is ensuring the USB power source can sustain 2 A across all three channels, otherwise charge rates drop to 0.5 A per battery.

Questions about this item

Will the charger fit in a small bag alongside the camera?

The charger measures 3 by 2 by 2 inches and weighs very little, so it slides easily into a compact camera bag or pocket.

How do I power the charger and what is the common mistake to avoid?

Connect the included Micro USB cable to any 5V 2A USB wall adapter, car charger or computer port; the mistake is using a 1A phone charger which slows charging or prevents the LCD from lighting.

When will the two NP-BX1 batteries need replacing?

Each 1240mAh 3.7V Li-ion cell delivers 4.6Wh; after roughly 300 to 500 full charge cycles capacity drops noticeably, so plan on new batteries every couple of years with regular use.
