Four-pack for Sony NP-BY1 cameras

This set includes four lithium-ion batteries and a quadruple charger built for the Sony NP-BY1 platform. Each cell delivers 3.7 V and 1100 mAh for 4.07 Wh of capacity. The kit suits owners of compatible Sony, Pentax, Ricoh and Sanyo action cams and compacts who need multiple spares in one purchase.

USB charger limited to 5 V input

The charger draws 5 V at 2–3 A (15 W) from either Micro-USB or USB-C. Output is 4.2 V at 800 mA for one or two batteries and 500 mA for three or four. It cannot charge faster than the USB source allows, so high-current power bricks are required to reach the rated rates.

Compact moulded body with status LEDs

The charger measures 3.5 by 2 by 2.5 inches and shows charge level and capacity on its display. Interchangeable plates let the same unit handle other battery types. A USB-C cable is included, while the Micro-USB port remains available for legacy power sources.

Each battery stores 4.07 Wh at 3.7V, giving typical run-time for the Sony HDR-AZ1 series and compatible Pentax, Ricoh or Sanyo models.

How fast does the USB-C charger actually charge four batteries?

The charger takes 5V 2-3A input and delivers 4.2V at 800mA for one or two batteries, dropping to 500mA each when three or four are charged together.
