  • 1Description

This Duo LCD Charger from Watson restores power to one or two DMW-BLF19 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 DMW-BLF19 Battery Plates is rated 4.9 out of 5 by 23.
    Rated 5 out of 5 by from Great Multi Battery Type Charger! Great charger. Well built. Comes with both wall and car plugs. Two great features are the display so you know how much charge batteries have and replaceable plates for charging different battery types. I use this charger for Panasonic AGAC160AP, Panasonic GH4 and BMPCC batteries. It's extremely convenient to be able to charge different battery types by simply popping in what ever plate you need. 100% more convenient than having to use a different charger for each battery type. I ordered a second one because it is so convenient. Batter adapter plates are cheap at $ a piece.

    Rated 5 out of 5 by from Fantastic!! I love this charger! Inexpensive, small, adaptable, fast, intuitive - what more do you want? I charge my GH3, LX7, and GoPro Black Hero 3 batteries on this puppy - many times two different batteries at the same time. I've had one set for a year - it went to the Galapagos and back - and recently bought another set to make my life easier - short money. The only negative I have is the plates are kind of hard to get off - so switching from one battery to another takes 10 or 20 seconds longer that it should. That's it. For work I had to spend hundreds of dollars for 2 different multi-battery chargers for high end camcorders so I was blow away at how inexpensively I could get set up at home. Buy Mr. Watson and don't look back.

    Rated 5 out of 5 by from Great Charger At first glance, the Watson Duo charger seems expensive. But it offers a lot. First, the LCD display gives a percentage readout of the battery's charge state, unlike most manufacturers' chargers. When I'm in a hurry, I might be OK with a 95% charge, but likely not with a 15% charge, and this charger lets me know. I like charging two batteries with one wall connection. The interchangeable plates mean that one charger can handle any of the five battery types I use, just by carrying cheap, small, light adapter plates. After using this charger for a while, I bought a second unit to enable more simultaneous charging. It's a little pricey compared to less versatile chargers, and bigger than a single-battery non-LCD charger, but for me those factors are more than offset by its adaptability, the charge-level readout, and the two charging slots. I'm very happy with the product and recommend it.

    Rated 4 out of 5 by from Great Multipurpose Charger Solid charger -- I keep two of these and have interchangeable plates for different batteries. Build is not perfect, but for the price it's solid. Four stars ultimately for a low volume, but high-pitched hum emitted from this charging unit. I travel for production and batteries charge in my room typically -- I have to cover the bright blue light and deal with the high-pitched hum while falling asleep. A very small, or non-issue for me, but most chargers do not have this. Great value overall.

    Rated 4 out of 5 by from Great for the price. I love the fact that I can see the progress of my chatrging batteries. This is a great charger for the money. The only reason that it didn't get a 5 star rating is because the quality of the build is not a 5 star build.

    Rated 4 out of 5 by from Good looking charger While charging gives a lcd screen readout of charge status. It can be used to test batteries with a test button, and can be powered by a 12v cigarette lighter cable with a 15 amp fuse (It doesn't look like you can replace it easily), so travelling is not a problem when batteries deplete. I have not timed the charge time, but that seems fast. I keep a number of these batteries (7) for my GH5, so power hasn't been a problem yet, but I haven't had a full fledged video shoot yet to test it.

    Rated 5 out of 5 by from Great charger Charged quick. Have ordered another base for my LED light battery. Worth the money so far. B&H service great as usual!

    Rated 5 out of 5 by from Excellent Charger I have 4 batteries for my camera and it charges the batteries as expected. the display makes it possible for me to know the status of the battery and use or charge accordingly. It serves me a lot better than the other chargers that show it is charging but there is no specific status on the % of the charge. It works great and I look forward in using it with no cause of concern.
