Or just use a battery pack or remember to recharge your phone?

For people constantly on the go or on the road that isn't so easy. That's the purpose of this article.

Most portable battery packs can charge phones and tablets to a full charge multiple times and have a 2 amp plug for quick charging. That's what I use in this situation especially since they're small enough to fit in a jacket pocket comfortably.

Can you combine #7 (the two USB plugs) with two 2amp chargers to get 4 AMPS charging!?!??

Yes, but you won't get 4 amps total. It will charge your device at the maximum power rating of 5v & 2.7amps, all in all 18% faster then 2 amps!

Well, then you need to charge the battery pack...

I usually stand on top of tall buildings wrapped in tin foil. 1 Lightning strike, 2 if I have my tablet usually fill the ol' battery meter right up. And instantly too!

Who even charges their phone from their computer? What's wrong with a wall socket?

What if a wall socket isn't close to you?

That's really only the case if you're traveling somewhere. The average person usually has access to a wall socket most of the time...

Then you need to get close to one because your computer's battery is more likely to run out before your phone's. External battery is a better solution. unless we are talking about sitting in your home but far from any socket, in which case any USB cable is good to keep your phone running for few minutes/hours till you decide to get to a socket and fully charge it. My point is that you don't need any of the above solutions to FULLY charge your phone from your computer/laptop, either use socket or external Battery Pack.

Since the Note 2, Samsung has went with 2 amp chargers for all of their flagships.

Windows phone doesn't charge while off. It turns it self on when you charge it off. Just saying.

If the tablet is something that runs only on wifi, just always run it with airplane mode ON...

I use a microUSB charger from my old blackberry playbook. I found it to charge very quick... Better than the supplied Samsung wall charger.

Never bothered me at all... I just swap the battery which I have already charged beforehand...

Really? It seems almost as though this article was written from a google search. I hate seeing the airplane mode myth perpetuated. Your phone barely uses any power to stay connected. Check the standby time for your phone... if it is able to last hundreds of hours when not in use, then the drain during a 2 hour charging session is obviously almost meaningless. Here is a more sensible list: 1. Make sure you screen is off and you aren't trying gaming while charging. 2. Use the wall adaptor that came with your phone. 9 times out of 10, it will supply all the amps your phone can take. 3. If you don't have the original adaptor or your phone didn't come with one, make sure you purchase one that provides greater than or equal to the amps that your phone can take. 4. If you get a car charger, apply rule #3. No reason to be stuck with only 0.5 amps.

or just use a charge with the original cable with 2.o amp

I charge through a computer so that the device charges slower, better for the battery, my RAZR was 2 years old and I was still getting 36 hours out of it.

What is number 7 called? micro usb with 2 usb ports? Also, if I use two stock wall chargers and plug both usbs at the same time in the wall, will it damage my phone in anyway or just charge really fast? I get an output of 2.0 A from each of those wall chargers. Would it be like 4.0 A if I used two of them at the same time to charge the phone or is it too much current for a smartphone to handle?

I purely use the provided 1800 MiliAmpere current SAMSUNG cables along with its stock 5.3v 2 Amp charger.for my Tab Pro 8.4 (I have two of these) for all of my handheld devices (3 phones, 2 tablets), man I tell ya, this charger is pretty efficient and fast! Those El Cheapo Chinese Cables are only capable of handling 500-800 MiliAmp current so you might want to AVOID those because they charge extremely slow. Buy only ORIGINAL cables, SAMSUNG USB cables are the best out there

Do you mean the white one ? I thought it is 5V 2A output (not 5.3V) How do you know it is 1800mA current cable ?

22. GreekGeek

Newer Samsung chargers come with a 5.3v 2A output, well within the safe limit and can be used with any phones and tablets There is an app called Galaxy Charging Current, gives pretty accurate reading, that's why i ditched every China cable that i had because i thought they were all the same lol

I think to charge a phone with 1A or 2A chargers will overheat the battery, don't you think so ? Most original chargers are 700mA.
