She arrived very well packed as always with Ravpower products. The package contained battery, instruction manual in English, French, German, Italian, Spanish and Japanese .... I think (one of the languages I do not speak so I do not know the characters!). To start I charged the battery by connecting it with the cable that comes with (I connected with a charger Ravpower I had already). After I had tested it using my iPod Nano and Apple cable. This battery, like all other external batteries Ravpower Smart has a connection, that means that the load is done automatically using only what your device needs and it also makes a lot faster! To operate the flashlight you double press the power button (there is an error in the instructions) and that's it. To turn it off you do the same. To check the battery charge when you press the power button
When you be trying to load a camera battery can heat a bit but that's normal, do not worry do not worry. Anyway at the end of the instructions you have contacts Ravpower if you have questions or problems and they have a very good customer service. The warranty is 12 months from the date of sale.
Note that the flashlight has a UV light and is used to authenticate tickets, and also identify potential false identity cards. If you have pets at home also helps find urine tasks that you normally can not see, as well as tasks in clothing, etc., três helpful.
