Kastar NP-BN1 Wall Charger

The Kastar NP-BN1 is an AC wall charger built for Sony NP-BN1 type lithium-ion batteries used in many Cyber-shot compact cameras. It suits photographers who need a compact spare or replacement charger for travel or home use.

Thermals Noise and Power Draw

The unit accepts 100 to 240 V AC at 50 to 60 Hz and delivers 4.2 V at 600 mA to the battery. A red LED shows charging while a green LED signals standby or full charge; no fan or active cooling is fitted.

Replaces Sony BC-CSN and BC-CSNB

This charger replaces the original Sony BC-CSN and BC-CSNB models for the listed Cyber-shot cameras. The jump is worth it when the original charger is lost or damaged and a foldable flat plug makes packing easier. Buyers who need a car adapter or European plug included should look elsewhere.

Questions about this item

How do I install the Kastar NP-BN1 charger and what step do people often get wrong?

Plug the foldable flat pins into a 100-240V AC outlet, then insert the Sony NP-BN1 Type N battery; the common mistake is forcing the battery in backwards, so align the contacts with the charger’s guide rails before pressing down.

What maintenance or replacement will the Kastar NP-BN1 charger need later?

No routine maintenance is required; keep the foldable pins clean and the ventilation slots clear of dust, and replace the unit only if the red-to-green LED sequence stops working or the output no longer reaches 4.2V 600mA.

What limit appears first when the Kastar NP-BN1 charger runs continuously?

The 600mA output current caps the charge rate, so a depleted NP-BN1 battery takes the full cycle time and the charger’s thermal protection may pause charging if the case temperature rises during back-to-back cycles.
