This Pearstone Duo Battery Charger for Sony NPF-550/570/730H/750/770/950/960/970/975, NPFM-50/500H/55H/70/90/91, NP-QM71/71D/91/91D conveniently charges two batteries simultaneously, drawing power from either an AC wall source (an AC cord with two-prong plug is included) or a 12/24V DC power source (a DC car charger is also included). Additionally, the Duo Charger features a USB power output to charge & power MP3 players, phones, digital cameras, and other devices with a USB power input.
With two easily interchangeable plates, the intelligent charger can also be used for other battery models that are not listed above – via the separate purchase of an additional battery plate that's compatible with the intended battery model.
The intelligent charger features an LCD display that graphically shows charge status for both batteries. This allows you to test batteries instantaneously, so you can easily decide which Li-ion cells to bring with you for the day. With protection against overcharging, overheating, and short circuit, the Duo Charger safely, conveniently, and quickly recharges up to two compatible Li-ion batteries and one USB-powered device.

Works very well with Sony NP-F970 batteries. Does exactly what is expected of a dual charger.
However, I don't like the fact that the battery adapters fail to stay in place. They are always dislodged when removing a battery.

Worked as advertised but interchangeable adapter for Sony battery releases from the charger base with the battery when you remove the charged battery. A better design to keep it in place would be nice. A quick fix for the end user: cut a small piece of double stick foam tape (3M type) and put it between the end of the adapter and the charger body. So far so good.
