The packaging looks like a small cardboard envelope, inside, there are the famous "carpet" Qi, which will make the connection between the charger and the S5 Qi .. I advise you to take it directly 0.5 mm for 0.5 already closed once the hull, one feels a slight bump at the back just below the heart / flash sensor. The outline of the battery cover at the / flash sensor and statement of 1 mm. I do not think the tightness being affected because the joint is a bit lower but still ... Very easy to set up, an adhesive strip is provided at the back of the carpet for it Glue the battery.
I use it on a charger Qi LG WCP-300 (I used at the time for my Nexus 4), and it takes time to load! Long! If you are pressed, board, plug the cable directly, nothing will go faster ... In a non precise calculation that I quickly made, from 77% to 87% it took 30 minutes ... So a 10% gain in 30 min ... Honestly, it sucks!
I have not taken the time to count with a lower load level, because usually I put it on the base all night and wake up, it is of course 100%.
It also heats! But I think this is mainly due to Qi charger itself and not to "carpet".
I still puts 4 stars (if the half was possible, I would put 3.5 stars), because I knew it would cause to the bump in battery cover with the comment of a buyer. And I suspected that the charging time is significantly reduced ... Even though I imagined he would still faster, BUT it may be due to my charger Qi LG WCP-300 which evil? With the Nexus 4 he instructed the faster I feel, but hey, maybe testing with the official Samsung charger?
If anyone has the answer and this official charger with the Qi carpet, he does not hesitate to comment on my review to tell me its charging time.
