One word: MiLi
I have the MiLi Power Shine, a 4000mAh external battery with two 2.1amp outlets.
Noticed you need more juice than me. MiLi has 10000-18000mAh externals too.

thanks im gonna check it

I have a Voltaic bag that I love - 16000mAh battery with big solar panels on the bag. They have a bunch of different models depending on what you need - www.voltaicsystems.com/

No problem! Also, if you want a solar powered backup, checkout Solio

I read some stuff on solar power chargers. I'm not so convinced about their actual recharging power. I'll go for external power pack for now.
Thanks for the replies. I'll repost here with details as to the performance of the battery pack I ordered....a Mili as kindly suggested above.

I had your same problem because of my traveling. I tried solar chargers and you can just use 'em to leave 'em home. I bought two batteries and car chargers (even the original Note ones - wich needs almost 1000mAh), then I bought the TurboCharger Proporta 7000mAh external battery. It rocks I charged my Note from 15% to 95% (power on) in 2hr 30mins. The TurboCharger fully charged an iPad 2, a Nexus S and a BlackBerry 9800 before die

how about those ebay single AA cell chargers? Are they any good for the note, or do we need a certain voltage or amperage minimum to charge?

Your biggest issue is going to be charging your Asus Transformer due to the fact it requires a higher voltage and USB 3.0 for charging.
Have a look at this topic on solar chargers for the TF.

Hyperion 5000 mAh extended battery and cover

After reading a few reviews on here about the generic eBay extended batteries and the overpriced Mugen extended one I decided on the Hyperion 5000 mAh battery.
It was available on Amazon for ~20 bucks + $4.99 shipping: http://amzn.to/xtT3Sf
Performance so far has been GREAT, twice as much as the stock battery probably more - i got 6+ hours of screen time! I would definitely recommend it over the generic eBay crap and the good but WAY overpriced Mugen battery
Here is what it looks like:
http://www.youtube.com/watch?v=0MjW2qYD62A

that is probably....the biggest....phone battery...that i have ever seen in my life

Holy crap that really is huge but I might entertain the idea of it because it'd be nice to have double the battery lol

I kinda like the idea of such a big battery for my phone... but it's just too thick.

The Razr MAXX does it right.

Kill it! Kill it with fire!
Had a flashback from the 90s

Battery sure does look massive.

can any1 give ebay link?

I have not seen this on eBay yet, but it is available on Amazon (see the link in the original post). With the Amazon option available, I wouldn't buy it from eBay in case you want to return it.
It is a big battery- twice as big as the regular one. But I gotta tell you though i have gotten some crazy screen-on and general use time from it. I am going to try to make a usage numbers screenshot in the next week or so when i take my Note on a 4 hour flight

Cheers for the heads up.... That's a beast! very handy for long trips. Juicy

I agree, and well-priced too. I may get one just for plane trips and when I will be away from civilization for a while. My Sat-phone can take the comms, my Note can take the gaming!

BTW, when I say plane trips, these can be of the 24-hour variety. One of the down-sides of living downunder

Personally I opted for a second battery plus the samsung charger. When one is on, the other one is charging... And I can bring it with me in the charger AND use it as a stall to watch TV...

hey buddy can u upload some photos of ur phone with battery??
how many hrs back up ur getting?

Wow! That thing is certainly thick..!
I'm still waiting on the arrival of my Note, but have a look at the "Tecknet iEP387".
Can't post links cos I'm still a noob ^^
To me it makes more sense that I can just sling an external battery pack in my bag to plug in whenever I feel I might need the extra juice. That and of course the 7000mAh capacity is higher (and can do all my devices).

the biggest battery i have seen....so juicy...might getting 1 soon

Erm... what's the advantage of that over a second factory battery?

well... have an educated guess.... maybe more standby time?
if somebody doesn't care about the size and is without power supply for a long time, it is perfect.

How thick is it? can it fit in my pocket???

Stand by time? Not by a long shot. Two official batteries at 2500 will have at least the exact same capacity of an aftermarket 5000, if not more.

3500 power bank purchased!

I got strong feeling that there are no 3500 inside but needs better to check out the tests. Let me know if u got questions, or need photo or video.

From a full charge of the bank, how much percent can it charge the phone battery to from empty?

Its still charging my phone. And i keep using it meanwhile. I started when phone battery was % 15 and it still run.
Right now battery is 35 and device has lost half of its power. I wrote in the evening final result.

I picked this charger from Thailand for 1000 Thai Bhat just last weekend.
Can charge the note from 45-60% from 1%.
Feedback:-
Not heavy
Sits like an added cover
Charging takes close to 4-6hrs.(Will confirm after few uses)
Charging is mildly slower compared to USB charging from a laptop or your wall charger.
Great for travelling and can fit into your pocket along with the Note.

I confirm everything. Can add that it charged my note from 50 to 100 as well.

The similar power packs I've seen for other phones name them so that the power is the total mAh you have with it attached.
ie. The Note has a 2500mAh internal battery, this pack has a 1000 mAh capacity, so in total your phone now has 3500 mAh of power.
Maybe this one is different, but judging from the size I'd guess 1000 mAh is about right.

Yeah, I dont either understand why people buy cheap crap batteries etc to their ~500€/$ phone. Like if you have the money to buy this phone you should have money to buy decent replacement batteries if you need them. But it is everyone's own decision if they want to risk burning their phone and in worst case scenario exploding the phone in their pockets. At least I wouldn't dare to risk my phone or my own health with cheap batteries. Peace!

tried a similar pack but with "4200mah". fully drains after recharging the note from 10% to 90% plus. and it takes forever to charge since input only allows 0.5A.

Wow Thank you,
i was considering buying this 4200 power pack but i think i ll just get instead an extra 2700mah battery.

I have bought powerbank with 5600mAh it takes little longer when charging cause output just 1A :silly: but it can fully charged my note for two times

It does really 1000mah inside? And also for other brand with 3500? Because im thinking of buying either 3500 power bank or 5400 extended battery.

What's up everybody, I just ordered these & hoping they'll do the job. I've ordered from them twice before (nexus one, evo 3d), the batteries in the past have held up pretty good but I don't think these have nfc :/ I ended up ordering these cuz' the qcell nfc enabled ones were sold out/unavailable so I didn't wanna' wait, plus I haven't seen a review on these yet so I said eh, I'll try em' out. If you guys are interested in purchasing some for yourselves I've included the link below, the only thing is that you have to pay using google checkout :/

another 3.7v batter that will die very fast if you use your phone to charge, due to overcharging. as our stock batteries full charge voltage is 4.3 where as that one is 4.2v
unless somehow our phones can distinguish the battery difference,

I always use the supplied wall charger that comes with these so Idk, lots of the extended battery reviews on here are the same voltage & they seem to be doing pretty good.

It's not the charger which matters but the phone itself which charges the battery, it's aiming for 4.3V as that's what it thinks it should have as the stock battery is designed for that. Although I haven't heard a single case of these 4.2V batteries having problems with being charged with 4.3V, that last part can be changed in the kernel and the charger chip driver. I'm getting some knock-off cheap battery myself so I'll see how it goes. This particular one seems quite steep in price @ $30, with proven ones like the PolarCell 2400mAh going out for half the cost.

you won't see the affect right away from overcharging. I use to play with a lot of batteries from RC, overcharging something we use to do get slight edge and boost at start. but it does have long term damage to batteries, specially lithium based. some cheaper batteries even catch fire.

Alright guys, got the batteries in the mail today, charging one & will report back later

Li-ion batteries have an overcharge protection circuit built into the battery pack itself and should prevent this from happening. If everything is working as intended, it should be impossible for the phone to overcharge a battery. That's not to say the protection circuit couldn't fail itself.
And I too played with RC batteries and you really can't compare those batteries with these. Different types of battery with different methods of charging.

Based off of Amazon, these batteries are the same size as the stock battery.

Any updates regarding your experience with these batteries? I used to own this brand for my HTC Sensation and was very pleased with it. Almost had about 400+ recharge cycles before the battery started to wear out. Looking forward on your feedback!

Highest slim battery in the world for i9300? 2980mAh Battery X-Level

So I was going through eBay AU and I found this 2980mAh battery at 3.8V by a company called X-Level (not sure if it is by X-Level but this but check it out!) and I wanted to share this with you guys.
Here's the link -
I just ordered one and I'm going to check out if this does lasts longer than the stock battery 2100mAh at 3.8V. I'm also going to compare it to another 3rd party battery (with no brand, *l'll post link of this as well below) that is 2300 mAh battery at 3.7V. Has anyone tried this yet? I'm willing to post results as soon as I receive my battery.
*Here's the link to the other battery I mentioned above -

Share your results please :beer:

Will do.
And oops, forgot to post the links to the batteries. Updated OP.

Anyone have any prior knowledge of the brand? For that price I doubt it's going to be good.

If anybody has experience with this, also chime in :good:

You'd think at some point people would quit falling for these scams, but I guess not. There's no magical battery technology out there that allows a manufacturer to pack more capacity in the same size space.

thank you for that information. if this battery is not what it claims to be, I'll ask this thread to be closed.

Toshiba (if i were not mistaken) has now made batteries that has capacities of like 5200mah in a regular sized 2200mah battery. Meaning more juice in smaller pack.

Companies have been working on better battery technology and it shouldn't be much longer before they start showing up for sale to consumers. That said, this isn't anything more than a cheap knockoff with a different label.

Completely forgot about this thread, my apologies. However after usage I can tell you that this may be a very good alternative to stock, cheaper, whilst offering similar performance. Definitely not 2980 mAh though, however it is not a terrible purchase for $10.
Also the battery seems to fall out very easy when you take the back cover off, it does not fit snugly.
