SONY BC-SAD1

Dual battery charger for Sony NP-SA100 batteries

The Sony BC-SAD1 is a dedicated dual battery charger designed for Sony NP-SA100 rechargeable lithium-ion battery packs. It allows photographers and videographers to charge two batteries simultaneously, providing a convenient way to prepare additional power for demanding shooting sessions. The charger uses USB Power Delivery technology to support efficient charging through a compatible external power supply. Its compact, low-profile design makes it suitable for use in studios, at home and while travelling. The BC-SAD1 is particularly useful for photographers working with compatible Sony Alpha camera systems who need to maintain a reliable supply of charged batteries during professional assignments, events and extended outdoor photography sessions.

Simultaneous charging of two batteries in approximately 115 minutes

The BC-SAD1 can fully charge two Sony NP-SA100 batteries simultaneously in approximately 115 minutes when connected to a suitable USB PD power supply. This allows users to prepare two battery packs during a single charging session instead of charging them separately. The charger also supports single-battery operation, requiring approximately 85 minutes for a complete charge under suitable conditions. When time is limited, one battery can reach approximately 80% capacity in just 55 minutes. Actual charging times may vary depending on battery condition, ambient temperature and the capabilities of the connected power supply. These charging options provide practical flexibility when preparing equipment for long photography sessions or consecutive assignments.

USB Power Delivery for flexible charging

The Sony BC-SAD1 is equipped with a USB Type-C input and supports the USB Power Delivery standard. For simultaneous charging of two batteries at the specified speed, a compatible USB PD power supply and USB-C to USB-C cable capable of delivering at least 45 W are required. Charging a single battery at the specified speed requires a USB PD power supply and cable rated at 27 W or higher. This arrangement allows the charger to be used with suitable USB PD wall adapters and other compatible power sources without relying on a proprietary charging connector. The USB power supply and charging cable are not included and must be obtained separately. For optimal performance, both the power adapter and cable should meet the relevant power requirements.

Individual four-stage charging indicators

The charger features LED indicators that display the charging status of each installed battery independently. The four-stage indication system provides a clear visual representation of charging progress, allowing users to monitor both batteries without removing them from the charger. This is particularly useful when two batteries have different remaining charge levels or when one battery is inserted after the other. The individual indicators help photographers determine when a battery is ready for use and organise battery changes more efficiently. The information is displayed directly on the charger, making it convenient to check charging progress while preparing cameras, lenses and other equipment for a shooting session.

Three-stage battery health indication

In addition to monitoring charging progress, the BC-SAD1 includes a dedicated Battery Health function for evaluating the condition of compatible NP-SA100 batteries. By pressing the Battery Health button, users can view a three-stage LED indication of battery condition. This provides useful information when managing several batteries that have been used over different periods or subjected to different charging cycles. Battery condition monitoring can help photographers identify batteries that may no longer provide the same operating time as newer units. The feature is especially valuable for professional users who rely on multiple battery packs and need to organise their equipment before assignments. The indication provides a practical assessment of battery health rather than an exact numerical measurement of remaining capacity.

Integrated temperature monitoring and charging protection

The Sony BC-SAD1 is designed specifically for NP-SA100 batteries and incorporates thermal management features to support safe and reliable charging. Its construction provides heat dissipation, while integrated temperature monitoring and control help regulate charging conditions. These features are particularly important when charging two high-capacity batteries simultaneously, as charging performance and battery condition can be affected by excessive temperatures. The charger is intended to operate with compatible batteries and suitable USB PD power equipment, following the manufacturer's operating instructions. Using the specified battery type and appropriate power source helps maintain consistent charging performance and supports the long-term reliability of the charging system.

Compact dimensions and practical portability

The Sony BC-SAD1 features a flat, low-profile body measuring approximately 84.5 × 36.0 × 67.0 mm and weighing approximately 130 g. Its compact dimensions make it easy to store in a camera bag, equipment case or small workspace, while the lightweight construction is convenient for travel and location photography. The two charging positions allow photographers to organise spare batteries in one dedicated device rather than using separate chargers. Its USB Type-C connection, individual charging indicators and battery health monitoring provide a practical combination of functions for everyday use. The charger is supplied without NP-SA100 batteries, a USB power adapter or a USB charging cable, allowing users to select compatible power accessories according to their existing equipment and charging requirements.
