Perfect portable battery,
Amazon Verified Purchase(What is this?)
This review is from: AnkerŪ 2nd Gen Astro2 9000mAh (3A Output) External Battery Charger with PowerIQ Technology for iPhone 5S, 5C, 5, 4S, iPad Air, mini, Galaxy, Nexus and other Smartphones and Tablets (Apple adapters - 30 pin and lightning, Samsung 30-pin adapter not included) (Electronics)
I'll start my review with the packaging, as this was the first thing i came into contact with. It's a simple brown (uncoloured) cardboard box, with a small thick paper overlay on the middle to keep it in place properly. It has a very nice "eco" feeling, and even if simple it has a quite nice and outstanding impact.
Upon opening, it was a nice unfolding paper cut-out with an xmas offer ( I assume will be removed in later batches), then the battery and cable each wrapped individually, the pouch and the typical booklets. The battery itself has a nice and smooth black finish, with a gloss finish on the connector sides and opposite. The pouch does a nice job to keep in one place the battery and the small cable provided (see below for details regarding the cable).
I was quite surprised that when I took the battery out I shook it a bit and the LED charge indicator lit up with a FULL CHARGE ! I wasn't really expecting that, but rather a long night spent charging it, so another white ball here. The manual states that while charging, it might lose up to 20% of capacity due to heating (I might be wrong regarding the percentage as ... come on don't judge me no one reads those manuals!). I haven't really tested it as there was no need to recharge it yet.
I used it to charge my PS Vita and it did an amazing job (the 9000mAh version). It went from nearly 60% to 100% as fast as it would do through the wallcharger, so nothing to complain here. It didn't used more than 1/5 of the portable battery so I assume there's plenty of juice in there for 2 charges at least; will edit the review if it's less, will find out quite soon when I'll fly back home. There are 2 ports provided, a Smart one used for devices requiring high mAh values and provides a fast charge, and a normal one that provides slower charges for devices under 3 or 2.8mAh I think.
The connector provided is USB at one end and MICRO USB at the other, with a micro USB to iDevice plug (up to the 4th generation will fit so no iPhone 5, 5c/s, iPad Air, iPad Mini or iPod 5th gen). It's quite short, not sure it has more than 10-12 cm.
To be honest, it would be nice if Anker would see this and consider increasing the price a bit but adding a wall plug as well. It would really make for a definitive and must-have package!
To sum it up, it's a perfect charger and I'm glad I chose this one in favour of the PS Vita portable charger which was a bit more expensive and I had no guarantee will charge my iPhone properly as well. Kudos to Anker

Hi, same questions I put to another reviewer but a second opinion can't do any harm eh? Am thinking of taking my iPad2 on a remote field trip to document/journal etc but I'll be in the wild with no source of power. Any idea how many times this would fully charge up an iPad2? Would help me decide whether to bother at all as I'll be carrying them both around in my pack for the best part of 5 weeks. Also does that mean it'll shake so much in my pack as I hike that it will have run itself flat? Cheers, Huw

Hi there, to be honest i don't own an iPad but i charged my Vita 3 times so i guess it could work at least 2 times on the iPad. Also really depends if you keep using it while charging. But if you'll use it for 5 weeks and no power supply around i'm quite sure you won't have plenty of juice. Of course it depends on how much you actually use it but i wouldn't put my head down 2 extra charges would help.
Regarding the LED indicator, that's not a thing to worry at all. Lately mine works harder, so i have to shake it quite good to light up. But honestly, LEDs barely take up some power, i'd say it has to run lit up for 8-10 weeks continuously to dry the battery

Hi thanks for that. Yes I figured a couple of charges of the iPad might be the best I could hope for. To conserve power I would expect only to turn the iPad on for maybe 30' - 60' per night to write up the day's journey so with a couple of full charges, it could last a good chunk of the time leaving a lot less transcribing from notebooks when I get back. So I need to decide is it worth it for the extra kit weight too as the iPad isn't exactly lightweight! Cheers. :o)
