I've been using a Mophie Juice Pack for years, I don't need it with the exceptional battery life in the iPhone 6.

I've never owned a power bank and I don't want something big and bulky, just something very thin and very light to keep in my backpack and obsessionally use in an emergency while traveling. I don't need something strong enough to do an iPad or have multiple days worth of iPhone charging either, looking to trade capacity for light weight and a slim profile.

Can anyone point me towards the slimmest, lightest charger that can get an iPhone recharged up to 75% or 90% in an emergency? Maybe something with the profile of a credit card?

Thanks.

BJ

Tech specs say 1200 mah, our iPhone 6 is out around 1800 mah, so to be conservative let's say it gives you half a charge.

Thanks guys!

What would be best for me (now that I know more) is something that can hold two iPhone 6 charges (3600mah) and can charge fast (2.1A)

So in that context, what would the best choice be in the slimmest/lightest form factor?

Power is lost due to conversions so the Jackery Air will be perfect for you. It is flat and holds 5000mah. 1800x2 is 3600 which leaves 1400mah left which will be lost in conversions.
Ask me any questions you may have.

Looks like this one only has 1A output though.

Oops.
I recommend this that has a 2.1 amp output.

I like the Jumpr Slate 5K-L from EnerPlex. It holds 5,000 mAh so it is good for over 2 charges, it is only 0.3 inches thick, and has a tethered lightning cable.

Nice at first, but dig deeper and the thing is as big as an iPad Mini, it even has holes in it to fit into a 3 ring binder.

Considering this one love the thin look plus has built in lighting cable no need to carry my own this one is attached.

Liked this one too, but at 1200mah it would only get me a single recharge when I'm running low, something at 3600 or more gets me two or three top-off recharges which is what I need in China as I travel without a power source from time to time.

This is the one I went with as it's small, lightweight, and I can charge it before I leave the US and wind up with 5 top-off charges during my 10 day trip, no need to bring a cable or re-charge it at all. At $25 it's a no brainer, seems to win the prize of max capacity vs. small size vs. low weight vs. 2.1 fast recharge vs. price.

Maybe you should get the 9000mah version or 12000mah version.

Too big and bulky. 4 or 5 top off's from 50% to 90% over a 10 day period in China is the goal and the one you recommended at 6400mah is perfecto from a size/weight/capacity standpoint.

Where do you do reviews? You have a blog or a YouTube channel?

Thanks again.

I've been reading several reviews on Amazon about how this product will randomly fail after a period of time owning it. Furthermore, people on the site are saying that the second generation charger line Anker released has been having several quality control issues.

Can you offer any insight into this?

I personally own a first generation product and haven't had any issues. The second generation line looks a lot better but it's unfortunate that it doesn't seem to be performing as well as the first one.

I own the first gen as well (the 2nd gen 6000). I own the version that came in matte black. It still works perfectly fine. I actually use it almost everyday as my main battery pack. No issues here. Contact anker support.
