Extra battery for the Galaxy Tab

[nnick]

Hi,

Do you have an external battery for the Galaxy Tab? I was thinking of getting this one:

What do you guys think?

It looks good and the price is attractive

I bought a similar battery 6-8 months ago for my laptop and it can also charge my psp, phones, pretty much everything

However, only buy it if you have a real use for it, such as travelling a lot ^^

Just keep in mind that at 750mA output, it won't charge the Tab while the Tab is in use. It'll spread the drain a bit, you will get more time out of the device, but it's not ideal.

Which one do you think would be a good solution? Is 1A output enough? Or maybe there is someone that could recommend a specific battery..?
I wil have to tavel a lot the next few months with lots of time spent in the airport waiting for connecting flights.

The galaxy tab need a 2A output...

It doesn't *need* 2A output - it just charges so much faster with it.

My MiniGorilla battery can charge my Tab, but does so very slowly and indeed works better if the Tab is off.

But does the battery handle the running tab? I mean does the battery of the tab discharge when it is on and used, while connected to the battery?

This one doesn't look half-bad, specs wise:

1.5A output is nice. Sadly, doesn't look like it comes with a car charger adapter for itself as well.

I've not really test it whilst using the Tab. I'll give it a try at some point.

Indeed not bad.

And, foxmeister, I am curious of the outcome if you test this with the tab running.

Ok, this morning my Tab had around 34% battery left.

I decided to watch some video streamed from my Tab to my PC via AllShare, and decided to try this whilst connected to my MiniGorilla rather than the mains.

I watched in total around 40 minutes of video, but it was off and on as I was doing other things at the time, including popping out to the shops for a while.

In total it took me two hours to finish, and in that time the Tab went from 34% to 54% charged.

Of course, this was screen off, so later on I'll try playing a video directly on the Tab and see how that affects the charging from my MiniGorilla. In the meantime, I'll set my Tab to keep the screen on for an hour and stream some music from Spotify and see how that affects it.

Dave

Thanks. Much appreciated. I will be waiting on info from your side.

Ok, so I tried this and the battery did drain around 5% in an hour with the screen on (auto brightness), and streaming Spotify through the internal speakers.

This would give the Tab around 20 hours worth of continuous use before draining completely.

So at this load, the MiniGorilla doesn't provide enough current to charge the Tab, but does considerably slow the rate of discharge. In addition, since the MiniGorilla is rated at 9000mAh, I'd imagine it would still have some charge in it at the point the Tab fully discharged.

This would definitely keep me going on a long haul flight, so I'm happy with it.

Dave

Thanks a lot.

Can we use HTC chargers to charge the tab?

 

[nnick]

Yes, it should work...

Yes, but it will charge slowly.......

Any other experiences with external batteries?

EDIT: nevermind my previous post - I can confirm that the Energizer XPAL XP8000 with the Energizer PC007 ipad charge adapter DOES charge the Galaxy Tab (it's rated at [email protected]).

The Tab will think it's connected to a PC, and the battery status will say "Not Charging", but Circular Battery Indicator widget went from 58% -> 60% over 20mins approx, so it is in fact charging.

 

[foxmeister]

Hi, when you plug the Tab into the Minigorilla, does your Tab recognise as if it was connected to a PC, or does it just start charging?

It thinks it is a PC, and according to the battery icon it isn't charging, though in reality it is.

I suggest that your XPal is probably charging it too - leave it connected a couple of hours with the Tab asleep and you should see that the battery charge goes up.

Regards,

Dave
