If you have the money, buy two .... leave one charging always at home and the other to take with you. Perfect situation. Awesome product

The 6000 is capable of 2 full plus a half charges for my phone. It seems that 2500 is needed for for a full charge so figure that the 9000 is good for 3 charges and change. Choosing between the 6000 or the 9000 depends on how many times you need to charge for a given time away from an outlet. Also size and weight is something to consider.

get the 6000mah. It will give you two full charge from it. I use a Nexus 4 and get two full charge from it and that is more than adequate for the day.

Hey man. Well I use my phone allot. Standard battery was at 15 % or less by the end of the day (unplugging the phone from charging cable at 5:30 am getting home from work at 9 pm) the new battery leaves me with 49% in the same time span. So I would say it gives me an extra 5 hours about. Depending on what you have running ( gps, wifi, 4G, blue tooth, auto rotation and the other sensors. ) if you use your phone allot in a day I would recommend buying one. It really does help. Charging time with Samsung 2 amp charger is about 15 min longer than standard battery. Hope this helps make your decision. Grtz Hey man. Well I use my phone allot.

I had a Ken-Batt-Pac-Chrgr for several months before it was stolen. Not only did it work w 3G-T, I found it recharged faster than a USP port on Mac. With some added cables and tips from RadioShack, IT BECAME MY 1st CHOICE CHARGER for: iPOD. Nikon batt, Nokia cellphone batt. The cel-batt tended to suck the Ken dry, unless fully charged. The Ken lasted much longer than an iPOD charger, and recharged faster than an iPOD. HOWEVER, it was useless for recharging my laptop!

If everything else is the same.The 900 will last longer before it need charging again and may take a little longer to charge. Hope this helps.

Hello there. Well it had many adapters which was great but I did not find that this product charged my Samsung smartphone enough. I ended up not using this and purchasing a Halo charger from QVC..excellent charger far superior to this energizer!

I let mine sit for ten days unplugged and when I went to use it it showed full charge still and it charged my galaxy S4 twice to full and still had at least 50% left. I like it. Even though it has 4 ports the strongest output is 5v. At 2mah which is what my phone takes. Dont know about multiple charging. But fantastic as long term stored power for your cell

It works great with the HD. That is the reason we bought it. It has the same power out as the Amazon $20 unit. Use the charging cable that came with the HD. Good solution. We use it with other devices as well since it is a faster charger.

I have an S4 (Verizon, but that shouldn't make a difference) and it works great. Though a little more flimsy than the more expensive ones, I found it charges just as well if not better than more pricey models. I got the receiver here Expower(R) Qi Wireless Charging Receiver Card Coil for Samsung Galaxy Note 4 IVA word of advice, don't get the Anker charger. They sent me 2 and neither worked with the S4

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.)

Shana, From what I have read (may be wrong), regular chargers pull energy even when not charging a device and they say they pull a lot of energy. This one does not pull power when your device is not plugged in. Your smart phone should control when it needs charging and stop when at 100%. I really like this charger; you don't have to worry about someone misplacing it. Also, easy to install. The top port is a fast charge and has a green light when charging. The bottom does not. I also ordered these and love them: Magic-T Bundle of 10 Durable Braided Nylon 3 Foot Micro USB Sync Cable Charging Cord for Samsung Galaxy S4,S3,S2,HTC One X, One 2(M8),Nokia N9 Lumia 9 Great deal. Hope I helped.

Not sure but they have one for the S3 and if you don't like to be with out power I highly recommend zerolemmon I have gone 2 & 3 days w\o charging my phone on purpose but I also recommend an external Battery charger because you have to cycle charge the battery meaning a full charge deplete repeat 4 to 5 times and battery usage will never be an issue screen brightness high screen duration maximum etc etc

You are talking about 11200mah vs 3000mah I own 2 if them and would buy a third if I had a use for it I would not buy the Anker that's just me

If I've read the 8.9 HD specs correctly, Id suggest spending a few extra $ for the 9000mAh version of the Powergen. The 5200mAh version would work...just not as fast or as full if a charge.

There is a good chance that the current output is not high enough to charge the battery really fast. Additionally, it is better for the battery's longevity to charge it slower. I would have to take out my multimeter to check into it, but my guess is that its good for over night charges and not super fast charges. What I recommend is purchasing a second battery and keep one charged up so you don't have down time. I personally have an S2 and when at conferences, typically pull out that second battery.

The sony charger I have will not charge my s3 fully. It also charges very slowly. Its portable and it does work, but I have a more powerful recharger for Samsung.

Hi, I just tried charging two Galaxy S4 phones with this device. They are displaying a charging status. What I don't know for sure is what charge current they're drawing. If there's a way to get the phone to tell me that, let me know and I'll check (yeah I could cut the cable and put an ammeter on it, but I'm not quite that curious...).
