Question: mine came with no directions, where can I find some?
Document: Now I need to find the cable that came with the camrea to charge it and I can't remember where I put the box. Very unhappy about this purchase.
The best price for the pack that I could find. Also, the batteries seem to last just as long as the battery that came with the original camera. It also helps that I have so many batteries in case the charge does fail me.
This is a good product. I couldn't find my camera charger after my vacation, and my camera did not charge by USB to the computer, so I had to buy another charger to get my vacation pictures to my computer! This came promptly and charged it up in no time. Also, the batteries that come with the kit are rated to last longer, so I can have more than a couple hours before I have to charge.
The pack includes a car cigarette lighter socket adapter... really handy especially with all my travels. By the way, the closest price I could find was $ 34 and that was just for the 1200 mAH battery and not the complete package.I would recomend this to any DSC W620 user.
I have not used this yet because I was waiting for my new camera to arrive, which it finally did. The charger kit actually arrived in two days just regular mail. I am taking it overseas with me and will be walking around a lot with my camera at hand for sightseeing photos I liked the price and what I got for the price. I believe it will do what everyone says it does but will find out in a few weeks in London.
This an excellent deal. I have it for my Sony Cyber-shot DSC-TX20. I use this camera for underwater pictures and as you can imagine this take a lot of time. Having backup batteries is a necessity. I find the Wasabi battery has a longer working time than the OEM. I would suggest this product for anyone looking for a additional battery and charger. Also the Wasabi charger plugs directly in an AC outlet offering quick chargers verse using the USB.
Can't beat this packaged deal, you can't find this mAH rating battery at a local store let alone have the charger come with it! It is double the mAH and lasts significantly longer. Highly recommended.
We always need battery's,and this is exactly what I wanted, and it came at a great price, value,and great service.
Because I take a lot of photos, it's important to have back-up batteries. These were relatively inexpensive and came with the charger. Arrived quickly too.
I am very satisfied with my charger. It also came with spare batteries. I received the product within days. Saved lots of money through Amazon.
Answer: You can see the electrical contacts (silver prongs) in the battery compartment of the charger. The battery has corresponding contacts. Put the battery into the charger with these contacts aligned, plug the charger into a  wall outlet (be sure the outlet is not controlled by a wall switch) and leave it charging until the red light turns green. The directions are on the back of the charger -- it doesn't matter if you plug it in right side up or up-side down. The car cord: big end plugs into the cigarette lighter socket of your car and the small end plugs into the hole on the top of the charger. Note: it may not be charging unless your engine is running.
