Kastar NP-BX1 Kit for Sony RX & Cyber-shot

This kit supplies a 3.7 V 1240 mAh lithium-ion battery rated at 4.6 Wh and a triple USB charger that fits one battery in each slot. It targets owners of Sony Cyber-shot RX1R, RX1RM2, RX100 through RX100 VII, HX and WX series cameras plus Action Cam models who need spare power on location.

LCD Triple Charger Sustained Operation

The charger accepts 5 V 2 A input and delivers 4.2 V at 0.5 A to each of three bays simultaneously. An integrated LCD shows real-time capacity percentage for every cell so you can monitor progress during extended studio sessions or multi-day trips without guessing remaining charge.

Installation and Common Issues

Insert each NP-BX1 pack into a bay, connect the supplied Micro USB cable to any 5 V 2 A source such as a wall adapter, car charger or laptop, and the display lights automatically. The only frequent problem is attempting to charge from a low-current port below 2 A which causes the LCD to stay dark and the batteries to not charge.

Questions about this item

Does the 5 V 2 A input charger get hot or make noise when charging three NP-BX1 batteries all day?

The charger runs from a 5 V 2 A USB source with three 4.2 V 0.5 A outputs, so total power stays around 10 W — well within normal USB limits and no fan is present, keeping heat and noise minimal.

What USB power source do I need to run the LCD triple charger at its full 10 W input?

Any 5 V 2 A USB wall adapter, car charger or computer port that can supply 2 A will deliver the full 10 W; the kit includes a Micro-USB cable for the connection.

Will the 1240 mAh Kastar NP-BX1 work in my older Cyber-shot DSC-HX50 alongside the original Sony battery?

Yes — the 3.7 V 1240 mAh Li-Ion cell is listed as compatible with the DSC-HX50 and mixes freely with Sony NP-BX1 or Type X packs in the same camera or charger.
