The tiny 2600 one charges my Galaxy S3 for 38-40% only before dying while S3 is on. When I charge with S3 off, it goes till about 70%.
The 7800 charges S3 for 2.5 times (while S3 is off). One problem I faced with 7800 is that the third blue light blinks for hours (7-8 hours) while charging (first two and last light take reasonable time - 2-3 hrs each to charge). This has happened for all the times I have charged 7800 using the supplied wall outlet. Anyone else faced this problem? I am thinking of returning the 7800.

Since you're having trouble with the cable(s) that came with your charger, I'm guessing you got a faulty one. You can try using OEM cables, but since those are usually charge/data sync cables(data pins not shorted), you'll probably only see USB mode charging with them.

|fungo45||I'm having issues getting this to work on all of my devices. I bought it right before we went on vacation in order to keep all of our electronics powered on the plane. It worked for some, but not all of the devices. Some of the 1 star reviews on Amazon talk about the issue being the USB cables that came with the device. I'll see if anything changes using the OEM cables from my phone. But if that's the case, I'd still give it a less than stellar review as them I would have to make sure I have the right cables for the right devices all the time.|

|sknsl||did anyone order one set and received 2 set? I received one set a few days ago, and received another set today.|

Kind of disappointed. For each full charge of the device, it can charge only
iPad3 from 2% to 52%
iPad2 from 2% to 95%
Not 7800mah....maybe only 6000mah I would say.

|illuminati||Received mine today. Overall, the batter pack is pretty solid and smaller than expected but doesn't feel cheap it's got some weight to it. Also, the flashlight is built into the battery which was very cool. All you have to do is just hold down the power button and it will turn on.|

|Armaan1||Just got mine...both are solid and work as advertised. The battery is small, but chunky and pretty heavy. I like it. Doesn't feel "cheap", either.|

|Propro||I used the supplied AC adapter to charge mine last night. That adapter was really hot after 3 hours. I changed to an iphone adapter for the rest of the charge and wrote to ravpower's customer service today asking for a replacement. I'm awaiting a response.|

|HastraJenaVosti||I received my 7800 today, but not the car charger...anyone else have this happen? Is it shipping separately or were yours in the same package?|

|slyger||for anyone still interested in one coupon 39XGQA88 takes 5 bucks off the 7800|

interested to see the rating on the LED too
Remember-> this means the battery pack has to convert from 3.7v * to 5v, then your actual phone takes the 5V input and steps it down to your battery's 3.7V*
(batteries typically go between 3.5V and 4.2V)
therefore, there are inefficiencies... maybe 30% loss of power for both steps due to step up/down and heat loss
your actual battery % increase in your phone should be between 1300mAh (2600*0.7*0.7) and 1800 (2600*0.7) minus whatever the phone uses up during those 3+? hours of charging
if you don't recharge them after a few months, it might completely discharge and you cannot recharge it again

|samtruong200||does it seem to be charging devices relatively slow? I'm not sure if its attributed to the lower amperage or something wrong with my actual device.|

Before you charge it, you can check the LED status. If there is >= 2 LEDs on, you should not charge it yet.
