Dolgin Engineering TC40-SON Four-Position Charger Kit with 4 x Watson NP-F975 Batteries

The TC40-SON from Dolgin Engineering features integrated battery plates that support Sony and third-party NP-F970, NP-F770, NP-F975 batteries. These batteries are used with Sony's HD1000U, Z5U, Z7U, MC2000U, NX5U, HDRFX7, and FS700R cameras.

The TC40 has semi-independent channels and provides Dynamic Power Management (DPM) when charging four batteries. This means that it allocates more power to the battery that needs it the most first. Once battery levels are equal it charges all batteries simultaneously with equal power distribution. The result is that all batteries will be ready at the same time. Based on a capacity of 5600mAh, the TC40 delivers a complete charge in approximately 4.5 hours for four batteries or when you charge a single battery. With the battery plates built in, the battery contacts are ensured to remain more intact.

Charge status is displayed per battery by indicator lights on the front panel. The TC40 comes with a U.S. power cord and supports worldwide power input via optional plug adapters, as well as 12 VDC car lighter power via an optional adapter (model # DE_CAR_12).

The Watson NP-F975 Lithium-Ion Battery Pack works with the same cameras as the Sony NP-F970 series batteries. This replacement battery pack features a capacity of 7800mAh, 7.4V of output power, and 57.72 watt hours. Small and lightweight, lithium-ion batteries can be charged or discharged at any time without developing memory effects.
