Mobile battery packs

[Connector]

Oh, I thought you had an ipad. The ipad pulls power at 2a and has a much bigger internal battery, so it differs alot from iphone charging. My external battery has no problems at all powering my iphone. It will charge fast and will always increase the iphones battery level. On my new ipad though, when being used, it loses about 5% an hour or so. Power supply loses about 0%. So I was kind of hoping that it could charge faster. It's a whole different case too if I have my ipad off with the battery on, it was primarily designed to be used in this format.

But for iphones, it should be fine, and 10,000 mah should be more than enough. I wanted 15,000 mah originally for my ipad but couldn't really find anything that worked. But if I was iphone only, probably 7000 mah would be enough. 10,000 mah should be plenty even for 2 iphones.

Yeah I was looking for the biggest I could find as well, I was looking at the power gorilla but it's a an awful lot more expensive and I couldn't actually find it's mah rating which worried me. To be honest though I think that's more for laptops and stuff and would no doubt be serious overkill for what I needed.

I think the one I bought will probably do the job fine worst case scenario I should get about 4 to 5 charges from it and I can't remember the power ever being down that long usually it's sorted same day.

Yeah, I would estimate I can get about 4 full charges on my iphone, which is quite a bit. For my ipad, it probably charges about 80% of one full charge, which normally is fine, but if I am using my ipad for more than 12 hours, it's not enough. That's why I wanted 15,000 mah, but the tech isn't there, either expensive or huge. 10,000 mah under your scenario should be just fine, and who knows if you ever get a tablet you can use it for that too. Good luck with it, let us know how you like it after a bit.

Did more digging on the power gorilla apparently that one is 21,000mah but yeah huge and expensive, they also claim it can recharge a phone 20 times which I find unlikely in honesty.

Wow that battery is big, almost the same size as my ipad sizewise. My external battery is about the same size as an small external hard drive so it is great suze to put into my backpack. I really doubt 20 charges, if it can get half that it would be lucky. But would love to have a battery rated that good, I wonder too how fast it could charge my ipad, whether it would charge anywhere close to a regular ipad charger in terms of speed.

I read a review on amazon.co.uk the USB is rated at only 1 Amp output so it probably would last for a long long time but I doubt it would actually raise the percentage unless the iPad was off in honesty.

Really I'm not sure if it's actually possible to power up an iPad while it's being used best bet would be maybe a battery that supplied 2 amps output might be able to.

Check this out, it's kind of interesting.

I check out Amazon, and Anker just came out with a new battery! And get this, it is rated 3A out, not 2A!!!

My older one, rated 2A

http://www.amazon.com/Multi-voltage-...ternal+battery

Reading through the comments, someone mentions that when an ipad is powered on, it needs at least 3.1A to power without losing power in the battery, so this new 3A model would seem go help my cause cause I use my battery primarily when my ipad is on, and don't like it draining.

I'm really curious about getting this one and seeing if it makes a huge difference, apparently, they should theoretically provide the same charge, but its how fast the charge will get into my ipad. It would help in my case a little cause during the day, I often have my ipad plugged into the battery now powersupply, and at night, I like to go untethered all night long.

But the new model for some reason doesn't seem to have a power supply like the old one did, and may take longer to charge up. I'm really tempted to buy one, it's actually cheaper list price now at $40 vs $60, even though I bought my old one for $40 a while back.

Would make a bit of a difference probably but I have read the new iPads ac adapter actually supplies 10 amps and still doesn't charge it if you are gaming or something.

I'd say probably depends what you are doing with the iPad I would like to think 3 amps would raise the percentage though even if it was very slow doing it.
