Advertisement Posted March 23, 2020 Posted March 23, 2020 Hi MarkinVan, Take a look here SL2 & USB-C Charging. I'm sure you'll find what you were looking for!
scott kirkpatrick Posted March 23, 2020 Share #2 Posted March 23, 2020 Recharging the battery while it is in the camera and the camera is switched OFF just requires a cable with a C plug and a source of 5 or more volts. It's not clear what happens when the camera is running. It seems the camera draws a fixed current from the external source. If that is not enough for what the camera is doing, I presume the battery is drained. If it is too much, maybe then the battery is charged. I wouldn't expect any trouble with the MacBook 16" charger, if that has a C plug output. My Mac uses a magnetic clip power connection, so I can't try it, but I have run my SL2 on the AC to DC charger that comes with a Lumix S1. Anker has an infinite number of products with similar capacities. I recently got a 20000 PD, same capacity but only two plugs. One labelled IQ (output A plug, like yours which has two of them) and one labelled PD (C to C connector). Yours seems older, and only says "input" over the C plug socket. The Leica technical data sheet says that its interface is simply USB 3.1 Gen 1, not PD and not Power IQ 2.0, either. I guess you just have to try them. 3 2 Quote Link to post Share on other sites More sharing options...
SJH Posted March 25, 2020 Share #3 Posted March 25, 2020 Yes in my personal experience you can use the Mac charger - I did this while shooting out in the Caribbean in February and the camera battery charges very quickly. Quote Link to post Share on other sites More sharing options...

Thanks This is the old model. You need the newer model with PD in the name. It has a connector with USB PD. But it is probably more expensive. I use the PowerCore PD 26800. ( https://www.amazon.ca/dp/B01MZ61PRW/ref=sspa_dk_detail_1?psc=1&pd_rd_i=B01MZ61PRW&pd_rd_w=eaDyB&pf_rd_p=a14ddd24-c45e-4c01-803e-ab6a335c1c48&pd_rd_wg=7oWQh&pf_rd_r=ZCJ6DKR8DTC44CA939KB&pd_rd_r=551c84be-6d3c-48b3-bf6f-368b93cd03df&spLa=ZW5jcnlwdGVkUXVhbGlmaWVyPUEyUzVUWktFQjQ2Q1cyJmVuY3J5cHRlZElkPUEwNzk4OTc1S1ozTVJTOTRFSlgzJmVuY3J5cHRlZEFkSWQ9QTA1ODU2MjczTkNBOUJDT1VOMFNQJndpZGdldE5hbWU9c3BfZGV0YWlsJmFjdGlvbj1jbGlja1JlZGlyZWN0JmRvTm90TG9nQ2xpY2s9dHJ1ZQ== ). It’s maybe equal to half a dozen batteries (you use it usually not to the last drop. If you use it in the range 15%-80%, the “life” of the device is optimized.) With the old one you can charge the battery, but not run the camera directly. For charging only you can use many different chargers, also older chargers from apple for iPads and MacBooks. But I would also suggest a charger with USB PD, like the latest models. And the Anker devices are very efficient (fast charging) and smaller than others (special material), so I would suggest them - e.g. powerport II or powerport PD . Even apple is selling them in their shop. Edited March 26, 2020 by caissa Quote Link to post Share on other sites More sharing options...
scott kirkpatrick Posted April 10, 2020 Share #5 Posted April 10, 2020 (edited) Having an external power port with a USB C socket in both the SL2 nd the S!/S1R raises two questions -- how easy is it to charge the battery that way, and is it a way to provide external power for long sessions, such as often occur with video shooting. I have a recent Anker 20 Watt-hour battery with USB A and a USB C outputs. The C output is also the input for recharging the battery and offers the PD protocol. And my S1R comes with a multipart battery charger, the first two parts of which are an AC-DC converter with PD protocol and a USB C output cable, which is carefully noise-damped with two ferrite shields. To find out what these actually do together, I invested $15 in a USB digital volt-ammeter, which you can see here as I charge the battery in my S1R from the Anker 20000: Welcome, dear visitor!

R1030006 by scott kirkpatrick, on Flickr Charging a battery in-camera is MUCH slower than doing it on a regular charger, at least on the SL2. Connecting C (PD) outlet to a switched-off SL2 with a half-drained battery, I measured a steady 0.49 amps at 5 volts until the battery reached about 80% of capacity (7.9 volts at the contacts). It took overnight to complete charging. If I connect the USB A output to the SL2 for charging, I get similar behavior but almost 3X the current flow, which translates into a faster charge, 1.43 amps steady. Watching the end of this process more carefully, I could see that the charging rate slows down at about 80%, dropping steadily to zero amps when the battery reaches 8.2 or 8.3 V open circuit. Once the battery in the SL2 was fully charged and no current was flowing, I switched the camera. on, I observed a steady current of 0.86 amps from the USB A port and 0.49 amps from the C port. The current flow did not depend on what the camera was doing while on -- focusing, taking a still picture, video. etc.. So I guess in the SL2, external power goes to the battery to replenish some of what the camera needs to run. I also tried using the S1R's AC power to USB-C PD adapter to drive the SL2. It delivered a constant 0.86 amps while the camera is ON. It's PD protocol provides some advantages when this is used with the S1R, which implements the PD protocol at its C interface. The S1R has a much bigger battery than the SL. Notice in the picture above, the Anker battery is putting out almost 3 amps, while charging an S1R. The S1R PD charger delivers 9.1 V to the S1R. In charging the battery, it outputs 2.79 amps at the higher voltage, so it will recharge about twice as fast. The behavior of the S1R when the camera is ON is also different than what is seen on the SL2. The S1R charger delivers 9 volts and about 1.1 amp when the camera is on but doing nothing much. That value jumps to 1.9 amps when taking pictures, 1.6 amps during video capture, so it seems possible that the external power is providing all the power needed for operation leaving the battery out of it.

Jeff S Posted April 10, 2020 Share #6 Posted April 10, 2020 (edited) On a related topic, I'm considering Michali's approach to remote charging, with the Zendure and Nitecore. Otherwise, if I'm home, I just use the provided SL2 charger and wall plug, and always keep 2 batteries charged (considering a third). Anyone know if there is a dual battery charger for the SL2 batteries? Jeff Edited April 10, 2020 by Jeff S Quote Link to post Share on other sites More sharing options...

Leicaiste Posted April 11, 2020 Share #10 Posted April 11, 2020 You are right. Only the M10 Nitecore charger accepts two batteries. Sorry about that. Quote Link to post Share on other sites More sharing options...
scott kirkpatrick Posted April 11, 2020 Share #11 Posted April 11, 2020 (edited) Using the Leica charger and a short cord to the AC socket is the simplest, safest solution. With the NiteCore chargers, if you leave the battery in after it is fully charged there is some slippage back as the charger switches off, but lets the battery discharge. This happens, for example, when you put a battery on to charge in the evening and remove it in the morning. And NiteCores sometimes will stop when the battery is only 80% charged. Their main advantage is that they can be driven by any USB power source. My post above is kinda long. Here's a TLDR: The best AC to DC source for charging things and external power is the S1 charger's first stage. It will give you 9 volts when camera can use it. Charging batteries in the camera is slower than on a charger because the camera doesn't allow as much current. Leica and Panasonic deal with external power differently. It doesn't seem like Leica allows complete external power, but rather just some backup. Edited April 11, 2020 by scott kirkpatrick 2 Quote Link to post Share on other sites More sharing options...

Maybe it is just me or it could be that I’m to old and come from the days where (digital) camera’s were fragile instruments with limited lifetime for the shutter for example. However it still feels to me that using an SL with an M lens for a zoom meeting is like towing a trailer with a Ferrari. Of course that will work but if I would be a Ferrari fan it would not feel right. Anyway, interesting to learn that people are using Leica equipment for purposes they were certainly not designed for. The little Leica purist in me conflicts here with the opend minded way that still keeps me amazed about other people behaviour and thinking. Interesting to say the least. And good luck with te setup. BTW I use a 200 € Razer Kiyo for zoom meetings with a build in ring LED. And an SL2 and M10 … for weekdays and weekends 😀 1 1 Quote Link to post Share on other sites More sharing options...
