Question: Does the charger work in the DMC-zs20 camera, as advertised?One review I read said it did not work in the zs20
Document: Some reviews warned that certain generic batteries and battery chargers did not work with their Lumix camera. I read the reviews on this one and decided to give it a try. The battery works fine in our camera and the charger works great charging both this new battery and the one from Panasonic that came with the camera. No problems after 9 months.
I was concerned about getting a second battery for my Panasonic Lumix camera that was not a Panasonic brand. I read that the factory brand was the only one that would work. A friend ordered these and they worked perfectly, so I tried it. I couldn't be happier. The kit was delivered to me before I expected it and it works fine in my camera. The charger could be used in my car or plugged in to a house outlet. Very versatile!
I bought this for my new Panasonic DMC ZS-19, and I couldn't be happier. Everything that was advertised was included in the box (charger, travel adapter, battery, cleaning cloth, screen protector). As I bought the camera and this kit for my upcoming trip to Europe, I was thrilled that they included an adapter for plugging the charger into Euro sockets. Very thoughtful.
Battery works in my DMC-ZS15. Doesn't seem to last any longer than the one that came with the camera despite having a higher mAh rating, but I haven't done a careful test. The charger is a little bulky, but still very handy and the accessories that came with it are useful.
I was used to the battery kits for my other Panasonic cameras as they came with the camera and very convenient. Also I would have a spare battery for them. I just couldn't imagine plugging the whole camera in for charging and once I got the DMC-ZS20 I tried it just to be sure and didn't like it. Plus I still would want a spare battery. So I began my search for a charger kit & battery and this one from Butterfly Photo turned out to be great.
Battery and charger for my Panasonic Lumix DMC-ZS20 worked perfectly. Camera recognized battery no problem. Battery runs longer than one that came with camera. Very pleased with purchase.
I take LOTS of pictures, & my camera didn't come with a charger. I had to plug in my camera to charge the battery, which meant it couldn't be used during that time. I had already bought a spare battery, but not a charger until I ordered this one. So far I've only used it once, but it seemed to work. My only 'complaint' would be that when it arrived, I saw the package was labeled 'Vivitar' & NOT 'Panasonic.'
I have not used the cleaning rag or the protectors but the charger and the battery work great. I lost my OEM charger for a Lumix DMC-ZS7 and this was a very cost effective replacement.
I like to charge my camera battery externally and this whole kit fits all my needs. The price is reasonable,  the quality seems to be good (all still work) and I would recommend it to anyone who has one of the cameras listed by the manufacturer.
After looking at many vendors, I opted for a battery kit for my new camera from Butterfly photo. The package of a charger, battery arrived in just a few days and has operated totally as advertised. good price and great value.
Answer: It has worked well for me. No problems even in Italy, using the extra prong-thing to adapt to their outlets.
