It says that it is 1A but I have read that is less power than 2A. I want to make sure this will really charge my phone fast.

This charges our iPhone 5s very fast. I am most happy with this charger and would recommend it for the 5s.

Just a further follow-up, it charged my iPhone from approx.15% to over 90% in about an hour. Hope this info is helpful.

You can use either one on your i5c 1A is 1 amp, it will charge your phone, not powerful enough to charge an iPad. 2.1 A is 2.1 Amps (more power) it will charge your phone faster, and would also charge an iPad.

Well, all I can say is that I use it with an Anker battery pack, which says 1.5A input current.As far as I know these new chargers, which output via a USB connector, establish sort of connection with a device being charged. And the device itself will only take whatever it is capable of.So it's not like the charger will shove those 2Amps down the device's USB connector.Your device is supposed to support whatever current is listed on the device. Otherwise it will just use as much as it is capable of.That's what I've been told.Hope this helps.

Because 2A is the power of the battery and 2000 mAh is the duration of the charge. Both of them are very useful data.

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.

1.5A is what it says on the sticker on the side. I can confirm that it's at least that as it charges my iPad fine and also charges my cell phone VERY quickly.

As others have stated you can't exceed 2.2 to 2.4 on a given port, but that wouldn't matter, because it isn't the charger that decides the amps to charge at it is the device. The only thing the cable and chargers do is supply enough amps and low power loss. An average device won't pull above 2 amps regardless of the output of the charger. The S4 pulls 1.8amps at its full draw and its oem cable and charger are rated for 2.1 if i remember correctly.

Not sure exactly the version, vut it worjs with my 2.0 and 3.0 ports. As for the two A type ports on the side for expansion, they seem to charge my cell phone just fine so I an guessing at least 2.0. Hope this helps. FYI, the unit is powered by a B type connection.

2A outlet is used for more power demanding devices, e.g. iPad, Samsung Note, or Samsung Galaxy S4 etc. For example, if you want to charge iPad, please use 2A. If you want to charge your iPhone, 1A is good enough.13000mAh is a big battery. It can charge smart devices many times. For iPhone, this battery pack could charge around 7 times. For Samsung S 4/5, it could charge around 4 times. For iPad Air, it could charge from empty to full and then charge an iPhone from 20% to full. This battery pack uses Samsung battery cells. The life cycle is also much longer than normal battery pack. It supports 1000 cycles of charge/discharge. 2A outlet is used for more power demanding devices, e.g. iPad, Samsung Note, or Samsung Galaxy S4 etc. For example, if you want to charge iPad, please use 2A.

That's a good question, but I don't know if it supports 2A charging. I use it for charging a MP3 player in my car. I don't have a 2A device to test with. Sorry.

The unit has two outputs. 2.1A and 1A, the 2.1A will charge faster, you can use it for any device. You should use the 2.1A for the iPad, or any tablet for that matter. I would only use the 1A if you need to charge two devices simultaneously.

Hi Terrence, The 1A is used for charging most smartphones and small devices. The 2.1A is used to charge bigger devices such as IPAD and other tablets more efficiently as they have a bigger battery. Having said that, the 2.1A is not limited to charging tablets, you can use it to charge a smartphone too and it will work just fine. Thanks, Omi Labs Store

It may be more than 2.1. My phone seems to charge pretty fast on it, it's an iPhone 6.

If it is a 2AMP charger that means when 4 ports are used .5A per port 2A/4 = .5 so if three ports are used 2A/3, two ports 2A/2 = 1A each port

Both should require the same 5v for charging. This charger has a 1 Amp and a 2.1 Amp output. The 2.1 Amp is stronger, but software on the tablet and phone should be able to adjust as needed. The issue is typically whether a third party charger has enough amperage for what the individual device expects. 1A and 2.1A should be more than enough. Plus this charger is sleek, sexy and solidly designed.

The packaging clearly states that the 2.1A is shared between the 2 USB ports. It says if you're charging a tablet & plug something in to the 2nd port, the tablet's charging rate will drop.
