why does it take so long to charge my galaxy samsung 10.1tab 2

Let it go completely go dead, then charge it overnight/all day until fully charged. After that, try not to let it die out if you can. But mine lasts for two or three hours at a time. Also check what programs you are using...that may be draining your battery as well. Hope this helps.

I let mine charge overnight and have had no problem. I don't know how long I can go without charging

What is long? An hour? My tablet doesn't take very long to charge or to drain the battery. I just put it on the charger every night when I sleep. If yours is not charging fast enough you might want to buy a new charger first and then if it still takes too long contact samsung.

It took my unit a total of about 7 to 10 hours to fully charge. If yours is not fully charged after 10 hours, it would seem like you might have a defective unit.

Thats a good charge time using their charger. If you use your Samsung charger and the phone it will charge more quickly

It will take 4.5-6.5 hrs depending on Samsung tablet (7.0-10.1), its settings and usage during charging. General rule: longer the cord, longer it takes for tablet to charge fully.PWR+

I bought this charger cord but never use it because it takes 2 days to recharge my Tablet with it. I'd still to Samsung original equipment if I were you

If I'm not mistaken, I see the charger you have only has 2 AA batteries, and I cannot understand how they would supply enough power to charge your Galaxy Tab at all. I'm just taking an educated guess here, as I am not familiar with your setup. This charger does have a 2 amp output USB connection, which I believe is the same as the standard Galaxy Tab wall charger, so this external battery should work fine while your tablet is powered on.

If the charger is working correctly I believe it takes about 40 minutes and the charge only lasts for about 5 or 10 minutes.

Thank you for your purchase. Does the Tab 7" uses a different cable? Did you try both ports? The difference in cable may be preventing the charger from transferring power to the Tab. Please try to update your Tab 7" to latest firmware see if that'd help.

I normally just allow my phone to get to 2% prior to charging it. I tried at 30% before and the phone seemed to die fast than before. It takes my phone a couple days to reduce to 2%. If it is at 20% I will play games for about an hour so I can throw it on the charger for the night. It does take a few hours to get a good charge on it.

I think I had the same issue. We used all the charge (drained) then let it fully charge. I believe the first time took approximately 12-16 hours. It does not charge quickly.

I know what you want to know, but your question has a slight error. You want to know how many mA (milli-Amps) this device puts out- not how many mAh (milli-Amp-hours). From the product description: Dual USB Charging Ports: Provides 1.0 amp of current when charging one device, and 0.5 amps of current to each port when charging two devices from AC or DC power. For AA or 9V charging, single port charging is supported. DC 5V +/- 5% 1000mA MAX So if your device is capable of absorbing 1000 mA (1 A), and you leave it connected for 1 hour, you would deliver 1000 mAh. Two hours, 2000 mAh, three hours, 3000 mAh, and so on. It's perhaps a fine distinction but it is important. HOWEVER- I think you may be disappointed if you try to use this as your primary charger for a device that requires 2100 mA of charging current (note I did not include the 'h'). It will only deliver 1A maximum, so if your Galaxy Tab will even charge from this device, it will take approximately twice as long as it would to charge from the Galaxy Tab's original AC adapter. HTH

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.

I have had my phone (Droid RazrM) and my tablet (Galaxy Tab 2 7") charging at the same time. The tablet uses the 2.1 volt port. Not sure if they got the same charge rate as they would have one at a time, but they both showed as "charging" while plugged in.

It does take a long time to charge. The reason why is because you are using the wrong cord and plug. I use my nexus 7 charger to my power pack and it still takes about 8 hours to fully charge

Jamie,It must be a bug with the tablet. This happened to me too when i bought my replacement charger but if you leave it plugged in, it will charge albeit slower than normal. Plug it in while using or before bed and you should be set!

The charging speed will be faster when it is plugged into the wall or using our docking station as opposed to be connected to a PC. Please let us know if there is anything else we can assist you with. RND

That is around how many hours it takes to charge mine when using their charger. It is done by the time the second battery is drained low from normal use, and then I just swap them out. If you charge one in your s4 cell phone using your OEM charger that the Samsung S4 came with, then it is much quicker.
