How much faster than a regular charger does it work?
764727
There is no set answer to this question. It all depends on your phone. If you have things like wi-fi, Bluetooth turned on or "Hey Siri" turned on, or lots of notifications such as Twitter/Facebook/sports etc. it takes a lot longer. If you have the phone turned off and charging it can charge very quickly. Especially if you use the two higher amp ports. if you are really looking for a quick charge, you should search for "quick charge" device chargers

That is a bit hard to say. It is faster by quite a bit since the amps are higher, but normally I have multiple devices plugged in at once. I would say that it is at least 30 to 40 percent faster. I also love the fact that it frees up my sockets.

This won't even charge modern cellphones as fast as most car-chargers (or that type of USB output that you plug into the cigarette lighter) can do. RE: John Taylor's misleading answer.2.1amp standard for USB3.0 and newer USB2.0 * 5volt standard USB socket = 10.5 wattsThis product's 0.5 amp * 12v = 6wattsUSB3.1 in 2015-16 = 100 watts!!!!! Try to wait for charging products that accomodate USB3.1 if you can; it's a HUGE jump in wattage & e.g. my Galaxy Note2 (USB2.0) take 8+ hours to recharge; also expected in 2015-16 are 1080p 3D head-mounted micro-LED displays worn like sunglasses for <$500 (mass-consumer price range) that draw ANOTHER 7watts or so.

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.

Not sure. It was a gift to my grandson, but I've heard no complaints about charging time.My experience in general is that charging thru USB is much slower than conventional AC charging.Doesn't the instruction sheet tell how long it should take to charge?

Definitely by using the included wall adapter. It's faster than using any kind of phone charger because the amperage is higher, 1.5 amps

It works but as many people have said, it take very long time to charge than the original charger

i have not rec'd mine yet so i can't be sure.I have an older charger that will do NiCad and nimh. it takes 13 hours ti do a set of 2 or 4. some batteries can be charged faster than others so I guess some chargers might charge faster than others.

Mine charges just as fast as the one that came with my phone. It works great!

Check the rated output of your charger. I've charged mine with chargers rated from 1 to 2.1 amps. Obviously, it charges faster with more current.

I don't know where you got this info, but the high capacity chargers for both devices are rated at 5VDC, 2.1A. So NO. And, if you charge at a faster rate the battery will fry!

Absolutely. In actual fact I'm using it to charge my Samsung S4 while im writing this reply. And on top of that it charges the phone from near dead to 100% in just over 2 hrs! If you ask me that's pretty fast. It comes with 2 USB cables and 4 different adapters for multiple devices. So you can use a computer or pop on a wall adapter to charge the anker battery. FYI it has 2 ports for charging. So the beauty is you can charge 2 devices at once. Only difference is one port is 1amp and the other is a 2amp. I stick with the 2 amp for quicker charge. Love it every time I use it.

Could take several days. The charger is a maintainer so it has a very low output current. It isn't designed to be a fast charger. it is designed to keep a full battery full.

It works but it charges very slow. In my opinion is better to by a regular charger.

It does charge more slowly than a standard wired charger. I have not tested to see to what degree but I find the convenience of simply laying the phone on the pad instead of wearing out cables to be an excellent trade-off.

Yes it charge faster than the original charger I have from my samsung note 3.

Yes, the wall charger will be faster. If you have USB 3 ports (Blue plastic vs Black) on your computer, it should be about the same. USB 2 will be slower than USB 3. I find the difference between USB 2 and 3, on my Galaxy S5, to be exponential (Like a dripping faucet vs a firehose).

It depends on your charger. I did not pay close attention but I used a 1 amp charger and it took about 2 hours or so.
