why The charging is very slow, I pluged it with Note 2 via wall socket for 12 hrs and it could only charge to 40% only?

I think it has to do with the mAh output. It does the same to me. If I plug it in at night it will be at 100% by the morning. But if its going dead and I'm on it, instead of charging when I plug it up like it would with the original samsung cord, it will die! So like I said it has a lot to do it the output of the charge. Hope I could help.

If you're trying to charge a note 2 it will take longer. The galaxy notes require larger amps to charge that's why the charger is larger than a normal cell phone. These cords are for smaller cell phones.

These cables are very lite gage and quite long. This causes a large voltage drop, making them unsuitable for charging.

Maybe the connection isn't making good contact. Make sure you have good connections.

I'm usung a dual port wall charger and there's one side that's for apple and other for android...the cable plug into the apple one was the one who charged slower but it was fully charged after 12 hrs. If I was you u would make sure the wall port is the right v for your device like 2.4c or 2.0v

Bc these are slow chargers so they dont fry your battery. I use mine for phone only and have no problems.

Most likely check you wall charger if its under 2.4A or 2400Milliamps output no problem. If its over that rating it might just charge a little slower in your car.I have not found any of my power hog devices that I can't charge. USB2 is rated at 500 MA and USB3 is 900MA so this charger output is well beyond USB3. Not much using this power level and the devices I have charge very well. I charge a Samsung Galaxy 10.1 note and it has no issue even when playing games during the charging.

I have the Verizon G2 and this charger. When it's plugged in to the included cable the G2 reports that it is "slow charging". If the charger and cable really were providing 2A then the phone wouldn't report that.

Its working fine with mine. Note charge fir 12hrs first time then drain to 20%Then recharge as normal , takes 4 charges before get full advantage of larger capacity

I called the Samsung company, and he told me to keep it plugged in the wall, and eventually it was a steady light and it started to charge. I let it charge for a while and it was totally charged. So try this before you go out and buy a new battery.

i am sorry. i meant if you use all ports the time to charge will "increase". it will require more time to charge. the charging is slow.

Cj, my problem was that the nexus just would not charge at all. Slow charging may be a battery problem instead. I am not sure. I think I would start with the power block and USB cords. Then move on from there. The factory charger is 2 amps, but many cell phone chargers will work. They just will not work as fast.

Have had no problems charging both the phone and case batteries, but it is much slower on the PC than a wall wart charger because the dedicated charger provides more current. I didn't time it but charging from 75-100% appeared to take around two hours. Try using a wall wart USB charger to confirm the battery will take the charge. If so, the PC USB current is too low to charge the battery...

I used it with the Note 2. My original charger worked fine at first, charging within a few hours. Then, the cable died and took hours to get about 20%. This cable takes just as long as my original charger did when it stopped working efficiently.

I do not know about your particular phone's charging issues, but with my Samsung Galaxy s3 I learned that the problem (and apparently a common one with Samsung phones) is that the USB recharging port has poor quality soldering. I've ultimately found that a better solution than USB charging or even using the Lerway wireless Qi "drop-pad charger" is to use multiple batteries with wall charging units. I believe I've written a review for such a product - it was around $20 for the charging unit and 2 spare batteries. I ABSOLUTELY LOVE how fast and efficient wall chargers/spare batteries are. I know have 7 spare batteries so I can keep several at home, a few in my office, a few in the car, etc. I can pop out a discharged battery and replace it with a fully charged on in about 15 seconds. Forget USB and drop-pad chargers.

I don't know either. But it seems a little slow when charging. Just my opinion.

That is my question as well. The charger keeps stalling, and I have to plug it in over and over again, but it only works for a few minutes (or less). Sorry to add this as an "answer" since it doesn't help.

I suggest that you contact the seller and let them know that you have a defective device. I did this and they emailed me a shipping label and returned my money. Mine would only charge my phone 10% then it died.

So far, charge has not been a problem. I keep my charge cable at work, where I'm the least active. When I finally sit down in the morning for a long stretch, I put the Pulse on the charger and top it off. So far, I've never seen less than 44% charge and that was over a long weekend (3 days off the charger).

I haven't had any problem other than the wall charger is a bit slow. Especially if you've got your phone hooked up to the USB port on the bottom.

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.

Your Battery Life Extender setting might be on. If it is, the battery charges only to 80%. You can check that by going to start menu-->all programs--->samsung--->easy settings--->general
