My cellphone charger output is 1A. This powerbank output is 2.1A, Is that good to use this powerbank to charge my cellphone?

Yes it will work fine. Giving your phone the correct current it is a smart charger

That's what I'm using one of them for. Works well, but make sure you get yourself a 2.1amp charger. You'll thank me later.

Using the DC power equation of P (power) = I (current) X E (voltage), 37.2 watts = 3.1 amps maximum output X 12.0 input voltage. I hope that this helps. It is good for charging a laptop, i-pad, or cell phone.

Well, it has micro-USB output. So I suppose so...But you need to be careful, it has a pretty big current! It is intended for a larger capacity batteries, like external batter bank.I use it for that.It says 2.1 Amps of current!And you device needs to support that charge current of course.

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.

not a matter as you will need extra charger of 5v and 1A output and 220V or 110v is the charger input matter not the power bank but please be informed that the mentioned power banck is not 20000mA it's actual 6000mA and it's not as described and 20000mA is false I don't recommend this product to you.

You'll be fine. The .7 and 1.0 amps have become a standard in cell phones and tablets. I use it with a Motorola Android phone, Samsung Galaxy Tablet and a Google Nexus 7 and it works just fine.

Yes one of the ports is 2.1 amps and will be able to. I have an LG G2 and it charges great

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

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.

There seems to be some erroneous advise posted here. I thought it advisable to repeat this:I own an iPhone 5s. It does not require a 2.1 amp charger. In fact, it will not charge faster with a charger rated above 1 amp.Also: the Apple Brand charger included in the box with an iPhone 5s purchase is clearly marked "5v, 1.0 amp".Fact: An iPhone will only draw a maximum of 1A of current, no matter the charger.

I don't know the actual output, but we have two of these and no one has had any problem charging anything with them. They are used daily for such things as phones, e-cig batteries and a Kindle reader. Hope this helps.

The best answer to you question is to refer to your manual and contact customer service. You definitely do not want to ruin your charger investment by not using the right charger. I have 2 or 3 of the Power-monkeys so this never became an issue for me.

I'm not an expert by any means, but it seems to my understanding that 2.1A would be more powerful than 1A. These numbers with the "A" refer to the input and output strength of the charger/battery pack. You have to plug in the charger first to fill it up so that you can then charge your phone or device. A charger with a 2A input means that when you plug the charger into a wall socket to charge it up, it will charge at a faster rate than if you had a charger with a 1A input. Same thing with the output: a 2A output charger will charge your phone or device quicker than a 1A output charger. I hope this helps.

If you look at technical details or product description, it states, Output: 5V 2.1a for this car charger.

There is a port on the side indicating 2.1 which is what i use for my IPHONE. Of course the one I have one has a 2.1 charging station 3.0 7-port 1 charging port.

It has input at 25v and output at 25v. Not sure if that is what you are looking for. I use this charger for my phone every time I travel. It has been a lifeline for me when my flight got cancelled. Bought my daughter one too.
