Does wireless charging take more time than cable charging? Cause there might be some energy loss due to electromagnetic energy transfer.

I would say slightly longer, but not so much you would be frustrated with it. I just leave it on the charging pad when I go to sleep when I'm really low or beside me in the office when I know I'll need a boost that day for traveling around.

That would be a function of the phone not the charger itself. I would have to say on my phone (Galaxy S4 Active), while it may not be charging, it gets very hot if left on the Qi charging pad overnight. I have gotten in the habit of charging during the day and removing the phone when it gets to 100%

I'd like to know this also. My understanding is anything induction-charged isn't very energy efficient. Convenient and safe, yes, but not energy efficient.

My understanding is when it is charging it does not operate wirelessly. I usually get 5 hours out of it.

Inductive charging (also known as "wireless charging") uses an electromagnetic field to transfer energy between two objects. This is usually done with a charging station. Energy is sent through an inductive coupling to an electrical device, which can then use that energy to charge batteries or run the device.

I have a external battery pack that can easily and reliably charge it. When I have this cable plugged it refuses to light up like its chargingWhen I have left it charging I did not notice any additional boost in charging time. Aside from the bump for the cable

Change your USB Cable! Sometimes using a data transfer cable for charging purposes can give you only USB power. I noticed sometimes also when trying to connect my phone to the PC using the charging cable, the data cannot be read or not recognized by Kies! So I'm guessing that even though they look similar there are 2 types of Micro USB cables, one optimized for charging, and the other for Data transfer. Mine did not come with a cable, so I used my own, and it works fine.

I think that it is a bit slower to charge than the charger that comes with the tablet. That being said, I still use it more often when I take it to work or vacation because the cord is longer.

i do not have difinitive answer; however, if you read carefully the accompaning instructions in some of these adapters, it reads "if you connect more than one device, the charging is slow.i if you use all ports the time to charge will "increase". it will require more time to charge.

Very poor charging time indeed!! I've seen where the 3' cord is 5W & this cord is only 2W. Probably why it charges so slow!I was also disappointed in the shipping speed to get it (not truly stated by supply quick) & the fact that I've torn up the packageand cannot send it back! (and I would send it back if I could)!

that is a good question... i assume that the usage/volt is essentially so low that it would be no different than a car charger-your radio left on in a car would use more energy. i think that it would be a good thing to always get in the habit of unplugging the unit. there are wireless transmitter sold on ebay from the UK and sellers claim they work in the US but I have yet to purchase one. its really personal preference I suppose.

Charging does not limit it's functionality, however using the device slows the charge rate, I.E. it will take longer.

If you are ok with wired not wireless charging. The powermat makes the charging magnetic without plugging wire to phone.

I think it charges faster than using a wire, at least it does for my Samsung Note 3. Be sure to either not use a case or use a thin case as proximity is a factor for the rate of charge.

I don't know the answer to your question. What I can say is this cable seems to take more time to charge phone/tabs and also I get warnings at time that I have too many apps running to properly charge the phone/tab all at the same time. That's when I'm browsing or gaming for example while plugged in. I believe these issues may be due to the length of this cable though I can't say for sure, this is just my observation.

Charging time is longer than normal. I have a Note 3 with usb 3.0 charging which normally takes an hour or a little longer to charge, with wireless charging you can expext to wait overnight...about 6 or 7 hours.

It doesn't take long... just about as much time as your cell... It is best to turn off any device while charging for faster time. I plug my unit in at night and charge while I'm sleep... since I only use in the mornings! Very neat with great sound... more than you really need in an average crowd.
