How fast can this charge a fully drained battery (say in a high end Android device, >2500 mAh) as opposed to plugging to a regular power socket?

It should be similar to your charger. If you use a two amp port it might be quicker if the device allows it. I have never timed it versus my charger.

In my experience, I have not noticed a difference in charging times. If you plug in an Android device in the Apple port, it won't charge any faster as it will only pull the max without destroying the device.

Perhaps you could clarify your question. This is a Lithium Ion DC storage device which holds 9200 mAhrs of power. It normally charges from an AC wall socket at 120 /240 volts (8-10 hrs). It can also be charged by USB connection to a computer (14-20 hrs, depending on the type of USB (3.0 is faster than 2.5). It can also use an included 5w solar panel, which takes about 20 hrs. There's no magic here -- the more watts you put in, the faster it charges. Connecting it to a car's 12v jack via a USB adapter would take about 16 hrs to charge. Most importantly, though, as a Lithium ion device, it's designed to have power flowing in and out all the time. When hiking or camping, we just let it charge on the solar panel during daylight, whether it needs it or not.

Depends how much drained. I charge my half drained 4s 5000mah in 2hrs. Hope this helps. I really like mine especially the safety feature that after fully charged it will not over charge your battery. This is huge for me. I sometimes tend to forget that I am charging my battery. Hope this helps to answer your question. Thanks. Dan

No. I have Galaxy Note and Nexus 10 -- both are charging at an abysmal 200mA ...very disappointing.

You can use your phone like it's plugged in a real outlet. 2 AMP output is more than enough to quick-charge and also use it. Same as a wall-socket.

I suppose you could - but the Pogo will fully charge the Nexus in about 30 minutes anyway, so any added effect from the usb would be meaningless. And as the other poster said, you might very well fry it.

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.

It charges my nexus 4, seems to work somewhat like a pass through. It will charge slower depending on device draw. Such as a 2.5in external hard drive will exact much more current draw than a flash drive.

if you use 2.4Ahr batts x 4 @ 1.2vdc each thats 4.8vdc 2.4Ahr.... (yes the charger actually uses 2.4vdc x 4.8Ahr) theres switching losses and controller losses in getting it up to 5vdc(20% ?) and your phones batt of 1.3Ahr also has losses in charging electronics(20% ?) as well as the battery losses itself(???)....... no one thought you could move and change power without loss.. did they? but still ~50% loss seems a little high... mabey it can charge it ~1.3 times? thats more like 20% loss on both devices as you might expect from cheap consumer goods

The unit that my daughter is using takes overnight to fully charge using a generic phone charger (micro USB) (5V 850mA).

I'm not sure if I understand the question. I would imagine the amount of time depends on what it's attached to. For me, I have a Galaxy S3 and it will full charge it from a very low level as long as I'm not using it too much. If I'm using my phone extensively while plugged to the portable charger, it will keep my phone alive about the same amount of time as a fully charged battery.

It depends on what you are charging..it will fully charge a 2150 mah in about 90 minutes. Hope that helps.

The included charger is rated at 1000mA, but my Nexus 7.2 only shows "USB charging", which I believe is 500mA. I hooked it up to my S4's factory 2000mA charger and got the same results. This is probably because the Nexus (and other devices) look for the two data pins, D+ and D-, to be shorted together electrically to indicate that the charger is high output capable. Since the Slimport adapter uses these two pins to transmit video data, they can't be shorted together and therefore the charger is limited to 500mA. That's not really Patuoxun's fault, it's just a limitation of the technology so any other Slimport adapter is likely to do the same thing. I hear that Slimport doesn't use as much power as MHL adapters, so this charge rate may be enough to keep the battery at whatever level you start with, or it may go up or down slightly. Haven't used it yet enough to find out.

Yes... I just got it and this is the first thing I tried. However, I think that it is largely dependant on the power source. If your charging adapter is 1.5 amps and your device draw is 1amp, I think the battery will have a slow charge. However if you use the 2amp charging port, you will be draining the battery faster than it can charge.

With 500mA US charger, it takes 4-6 hours to charge this from zero to full in my case.

2-3 hours maybe, higher mah longer charge time unless you get one of those 100 dollar chargers lol

sorry for the delay answering..as the others stated, some devices charge faster than others on it. I use it for cell phones, Samsung MP3 players, and my Kindle Fire HD. As previous people reported it supplies 500mA.
