Bought this for keeping my devices topped up on upcoming long haul flights, and while I haven't tested it in this capacity yet it is doing a great job of saving my phone when I'm about to go out and it's on 9% (and even when I can't be bothered to find a mains socket)!Takes a while to charge so I generally have charged it overnight and it's good to go, so no complaints here. Good size for the capacity, not very lightweight but certainly light enough for travelling with a bag.Lovely sleek design that feels quality, LEDs look good but I'm not 100% convinced they dropped accurately with the battery as it was on 3 LEDs for ages then dropped to 1; but that could be my perception.Charges my Nexus 5 and Nexus 10 extremely quickly, in fact it charges the 10 faster than the Nexus mains charger I have for some reason. Definitely a top quality product and the IQ charging lives up to the hype. All I wanted was a compact battery pack that would hold a couple of charges for my devices and would charge them rapidly, and this does all the above.Overall it does everything I wanted and comes in lovely packaging with a great mesh bag and USB cable. Only time will tell how it holds up, but great so far!

This is a brilliant device. Especially for ladies with handbags, as it can charge your phone conveniently in one corner of your bag.In terms of the functions, it is very well thought out. Information for battery charge, a built in torch, 2 usb ports which charge at roughly 3 amps ( this is very good btw ) while it charges its own battery with a 2amp input ( this is normal ). Sometimes I find myself using this to charge my phone faster then if I had a wall charger. I charged two devices impressively fast at the same time. One being a one plus one phone and the other being an htc one x. I bought this size due to my power requirements. It is a fairly chunky size, which has been designed really well with curved edges and shiny gloss finish to distract you from the size. With that in mind my only advice would be to find out the size of your batter in mah, and then decide how many times you would like this charger to charge your device and then choose your size. This means you can get the right size for you. In terms if size, it is worth noting that there is a size to power ratio which no manufacture can get past at the moment, so the more power you need expect it to be much larger. No fault to Anker, I think their design is beautiful and I am very happy with my purchase.For peace of mind, it's worth noting I have other Anker devices. I took a punt a while back by buying an Anker device, and I was very impressed of the quality of the manufacturing. I am now sold on their products and would not hesitate choosing Anker over other well known brands. The price is always competitive and their products perform.If you do buy an Anker product, do post your review as good products deserve our time and voice!

Solid piece of tech, supplied with a drawstring bag and USB cable - though you'll need either a plug end for it to insert in (chances are, if you have one or more smartphones, tablets, etc. you'll have them) or a separate power supply with a microUSB at the end (the sort of plug you can pick up from a tech store or get with a BlackBerry phone).You plug it into the mains to charge it (and it comes partially charged so that doesn't take long). Then you can use the two integral USB ports to attach the Anker battery to your devices. The trickle feed from the battery charges up your device - and doesn't interfere with your using it. I have used it on a smartphone and a tablet at the same time. Indeed, I used the smartphone to do some work on a Bluetooth keyboard and used the Anker to keep the mobile charged. Worked perfectly well.The battery can get a little warm while charging, but I have had no issues with it. An illuminated gauge on the side shows roughly how much of a charge the Anker has left - it should handle several partial recharges.I plan to take this with me on trips. I do a lot of exhibitions and conventions where you can never guarantee access to a power point during the day. Sometimes, in the past, I have found a power point somewhere distant from my stall - and trusted no one would pick up and walk away with my phone (and charger) while I had my attention elsewhere. The Anker battery means I won't need to worry about that anymore. I can recharge my devices during the day and then recharge the battery overnight.In the long term, I'll probably come back to update my review. We'll see how the battery and its capabilities hold over time and use.

Do you need this?Good for someone who goes places.Specially if you go on trips where you cannot access electricity or car charging readily, this is for you..But if you goto a workplace where there is a charger, and stay at home most of the day,where charging is not an issue, then this is of limited use.Capacity- Very acceptable. Can use to recharge a normal phone around 4 times.Charging indicator is present.Price- anything below £20 would be a good price for this..

So I was after a power bank small enough to be carried around in my jacket pocket. Yet big enough capacity to provide charging for any and all devices on the go.This Anker 2nd Gen E4 Astro fits the requirements perfectly.The packaging is simple and recyclable which is nice to see these days.The item came with the power bank and a Charging cable and mine was showing fully charged on arrival.On one charge so far I have charged a Nintendo DS from flat. Samsung A3 from 7% to full and a LG G3 from 15% to full. After all that it only dropped 2bars.It has 2 usbs which is very handy and makes charging multiple items at a time a breeze.Also has a handy little led light on it for emergency cases.The Only downside is the gloss finish, A matt finish would have made the product a light be more though out and polished product.I highly recommend this item. If your after a sleek device with multiple ports and can give multiple charges per charge of the power bank.
