Why does the "Manual" say use your device charger but the label on the Pulse states that the maximum input is 1amp? My Galaxy S4 is 2amp!

The Battery (MaxPulse) Charges (input) at upto 2 amps. The Battery has two outputs, you can use either, the first charges at upto 1 amp, and the second charges at upto 2.1 amps I would suggest using the 2.1 amp side for your Galaxy S4.

Indeed. I'm in fact responding to you right now on my S4 while it and my ipad are charging. I was concerned when I received it because the packaging alluded that multiple requiring 1A could be charged at once but only one if the unit requires 2A (like an ipad). I can confirm however that I can charge my S4 and ipad at the same time. It may take longer, I'm not sure. But if I plug both in when going to bed, both are charged when I wake in the morning.

I would check with Wagan to be sure, but as near as I know the output from any port is standard USB at 2.1 amps. I hear some Samsung devices have problems due to their proprietary wiring of USB.

I would say this link could shed some light on your issue. http://lmgtfy.com/?q=s4+maximum+charging+current

I believe the grey cable has two pins shorted together. This "tells" some phones that the phone is connected to a high current charger. Some phones will draw more current and charge quicker if they think they are connected to a high current charger. You want to consider both the charger and the device being charged.Different devices respond differently. I have a portable GPS which will not charge at all if it doesn't have the right cable.

Are you sure that the S4 should draw a full 2/2.4A? Those are ratings from those chargers, but that doesn't mean that your S4 will draw that much current. Someone did some tests with different chargers and he never broke 1.3A: http://forum.xda-developers.com/showthread.php?t=2274321 If you have evidence online that the real-world draw of the S4 is greater than 1.3 then the problem is *STILL* with the cable or charger OR the charge regulator inside your S4. It is *HIGHLY* unlikely that the PortaPow is the problem (though not completely impossible). (Oh and sorry about alzyee. There are a lot of idiots in the world.)

I've charged 1amp devices in the 2.1amp outlets with no problems. I have. Blackberry which will not charge off the 2.1amp outlets for some reason but no damage has been done to the device

Don't think I'm a good one to ask as it has NEVER charged faster for me than a regular charger. I gave a review saying this and it was denied publication.

Most phone chargers put out 1amp for phones... This gives you the capability of 2amps which should be sufficient to charge a laptop

Don't know what you've looked into so far, but some initial thoughts: 1) although the charger provided may be 2 or 2.1 amps, is the GS4 itself actually rated to charge at that speed, or does it perhaps max out at a lower rate? 2) good you tried different cables, those are always a likely bottleneck - btw, the original samsung cable isn't particularly good for charging, I got higher charging amps out of monoprice and other 3rd party cables. 3) if battery is near full charge, most phones will step down to a lower charging rate - try with a fairly empty (eg 50% or less) battery to see what happens. 4) if you have another device, ideally a power-hungry tablet, see how many amps those will pull on the same chargers and cables.

I dont remember exactly what they said , but something like just use a good quality charger . so i've been using my Samsung Galaxy phone charger and its been working great ! The light dim's when finished . The speaker lasts at least 8 hours no problem ! I tell you , I love it !

Look at the charger that came with the Galaxy Note 4. On the side, in small type, it should have an Output line. My wife's Note 3 says 2 amps. I am pretty sure yours will be the same. You can use the 2.1 amp without any worries. If you use the 1 amp, it will take a long time.

I just looked at the manual for the S4 and it appears to use the same cable as most, if not all other Samsung phones. I have owned three Samsung phones, two Galaxy and one flip, they all use this cable. In conclusion, I believe that Samsung OEM 3.3-Feet Micro-USB Data Cable for the Samsung Galaxy Note 2 - Non-Retail Packaging - Black will work on the S4.One other important note is this, use a Samsung charger for your phone. A recent news report concerning iPhone batteries blowing up because they were being charged improperly by off brand chargers. In the report the repair center said that the problem was not isolated to only iPhones, and that some other brands were experiencing similar problems.

I have one of these and charge Samsung and iPhone's on it (and up to 4 devices simultaneously). However, there are no AMP markings over the ports and the "owners manual" that came with it does not specify. With a supplemental power supply, you shouldn't have any issue charging, but it may not be "rapid charging".

Drew. There are two outputs with different amperages. 1 and 2.1 amps. Look at the picture above. If your phone charger is lower than 1.75 amps, I would use the 1 amp, just to be safe. If it is above that, it will charge faster on the 2.1 amp output.

I have a related question: I have the unit and I have an extra phone charger that fits the charge input. Can I use it? lol I ask because I want to make sure that the two are compatible and I won't blow out the battery by plugging it into an AC adapter. ;)

Hello. From my understanding and current tests. The higher capacity device will pull 2A. And the lower end device will pull 1A. I have ordered a USB Meter to see if either USB port is designated solely for 2A. So far. The panels put out great power and I am satisfied. I haw changed an iPhone4, iPad mini no retina, lg android, 12000 Mah newtrent power extreme battery bank, 5200 Mah brightech battery bank, and eneloop rechargeable batteries with the eneloop USB charge adapter. All devices function and chare fine. The phones and tablets will read an error of power soure of the panels are not in direct sunlight. It's an easy fix. Just position the panels on the sun again. I highly recommend a external battery bank. This way you store the unused power. No sense in wasting free juice. Hope this helps.
