  • 1Description

This Duo LCD Charger from Watson restores power to one or two NP-FW50 batteries via the included, dedicated plates. These can be replaced by optional plates for various other batteries. Additionally, the Duo can simultaneously charge two different batteries with different voltages. Charging time is between two and six hours. The unit also features a USB 2.0 port, which enables you to charge and power a mobile device while your camera batteries are being replenished. The LCD screen displays each battery's charge percentage--even when the Duo is unplugged--via the test button.

Running on 100-240 VAC power, the Duo can be used all over the world. It includes a power cord with a 2-prong North American plug, as well as a 12 VDC car charger that plugs into a cigarette lighter.

    Duo LCD Charger with Two NP-FW50 Battery Plates is rated 4.4 out of 5 by 106.
    Rated 5 out of 5 by from The Awesome Sauce! I bought this product not knowing about Watson. Normally, I am very weary of after market items. Well, the display on this is nice. It gives you an accurate reading of current status. I also bought a few of the add-ons that clip into the unit. So, now I just need one charger for my Sony camera and Canon. The add-ons are very inexpensive. It's a strange business model, but an honest one. Normally, companies will up charge the heck out of these things to keep the profit up. Not so here. It's a solid unit that charges in less time. I love it an will be buying more add-ons as I detest having to have three charges for all of my equipment. You can also mix and match while charging. Cool...

    Rated 2 out of 5 by from Not accurate at all As others have mentioned, this charger seems to have trouble with Sony's FW50s. The battery might be at 11%, put it on the charger and it says 40%. Let it charge to 100%, put it in the camera, battery is only at 79%. Tried both positions. Swapped plates. No improvement. However, It does seem to work fine with other batteries. I have plates from several other camera batteries and they all charge perfectly fine and report the correct percentage. Would NOT recommend for Sony NP-FW50. Better to by two of the cheaper, single chargers.

    Rated 5 out of 5 by from Update to my earlier review In my earlier review, I mentioned the chargers worked great with all my batteries EXCEPT the Sony FP-W50, for which it was bought. Watson read my review and reached out to me. They determined that I had a faulty unit and replaced it. The new unit works 100% as advertised. Reports the percentage on my Sony batteries correctly and charges them fully. Happy with the product now and very happy with Watson's customer service!

    Rated 3 out of 5 by from Works great, but not with NP-FW50 batteries Works as advertised, with my big Sony NP-F970s, Watson NPF975s, Canon BP511 and LE-E6. Not a single issue. Things are not as rosey in the Sony NP-FW50 world however. The unit cannot figure out the battery level. When it charges to 100%...even if I leave it on the charger for an extra hour...put it into the camera and it says the battery is anywhere from 92% to 78% (!). Removing a battery that the camera says is at 33%, put it on the charger and the charger says 5%....for about 60 seconds. Then it jumps to 60%. Then it's 100% charge in another 25 minutes. Camera says it's at 80%. I've tried 4 different adaptor plates. Both charger slots. Doesn't matter. The unit just can't reliably read the charge level from these batteries. However, works 100% fine with all my other batteries. So do NOT buy for Sony NP-FW50.

    Rated 5 out of 5 by from One device to charge them all! This charger is well thought out. Removable battery plates to fit multiple batteries is a brilliant idea. Now I can have one charger to charge all my batteries from Sony to Gopro, this charger has got you covered. The addition of an USB port for charging your phone or, in my case a dual battery charger for GoPro Hero4 batteries(only because they haven't developed a battery plate yet) is another bonus. The charging LCD is easy to understand, no weird codes or blinking lights to know where your charge is. Just a simple percent charged and a picture of a battery gradually filling up. A well designed, charger that helps reduce the amount of gear I have to lug around is a plus in my book. And it works great too!

    Rated 2 out of 5 by from confusing information regarding status of Sony NP-FW50 This unit holds two batteries in the Sony NP-FW50 plates that came with it. The first thing I noticed was the unusual sense of resistance at the pin end as the batteries were pushed into place. The lcd screen went through an interesting listing of apparent measurements of the status of the batteries before going into charging mode. That's when it got interesting. There is variation of capacity of a given batterie which does not agree at all with the reading when placing the battery in the camera. I almost tossed one battery because the unit indicated zero capacity regardless of which location it was in. Fortunately I put the battery in a camera on the way to the garbage. It read 100% charge. Putting it back into the unit yielded a 95% reading from which it has now been showing a charging pattern but with no change int the charge level of the battery. This experience has shaken my confidence in this unit. I will continue working with it a while longer, but if this kind of erratic reading continues, I will ask B&H to let me send it back to them.

    Rated 3 out of 5 by from A good charger, but could be better In general, it is good, but the issues mine has, - There are plastic burr not be removed in LCD, which reflects QC is not good. - Left and right display measurement are different, for say, after a full charge, left indicates a 100%, but right indicates 95%. - Test data is different from camera, about 25% difference. i.e., put a used battery onto it, test result is 40%, but put battery into A7R, it indicates 25%. Good thing is - I buy another plate, so, I could use it to charge both of A7R battery and or EM1's

    Rated 5 out of 5 by from Nice addition to any setup you may have. This dual charging system is great! I use it to charge my Sony DSLR and Action Cam batteries. You can buy inexpensive battery plates (made by Watson) to work with different types of batteries. If I could I would give this product 4.5 stars. At night when the batteries are charging I can hear a high frequency noise coming from the charger. It is typical however, most charging system do this. Also, the LCD display seems a bit pointless/useless to me. It shows you an estimate of how much the battery is charged (less than or equal to 25%, 50%, 75% and 100%). I always let my batteries charge 100% before using them. That's just me however, perhaps it's useful for others. Still a great product and I don't travel without.
