Colour Name: 16000mAh (Black) Verified Purchase
It arrived quickly, securely packaged. The instructions are clear and simple.

The item itself is chunky, not too heavy and gives an impresson of solidity and quality. It just looks ... an attractive bit of kit. It arrived (I would guess) about 80% charged and it took about 45 mins to charge fully, when connected to a USB port on my PC.

I am delighted with this unit - it seems to do exactly what it says on the tin! The tiny gripe? The two connectors supplied (one Apple 30 pin adapter, one Samsung ditto) look a bit flimsy (and Samsung is misspelled!). Not a worry for me, as I'm an Apple user and would use the USB connectors supplied with their products.

Review edited 19/9/13 and this added:

I charged the Anker Astro E5 fully and plugged it into my iPad2, which had only 1% battery capacity left. These were the results:
After 1 hour - 34%.
After 2 hours - 63%.
After 3 hours - 88%.
100% capacity was reached after a fraction under 4 hours (about 3hr 55min). There were still two lights showing on the unit, indicating 25-50% charge remaining.

Frankly, I think that is superb performance! Delighted with the product...!!!

Colour Name: 16000mAh (Black)
Recieved as a christmas gift in Dec 2014, more than happy to receive this!

From the get go, it was fully charged (I assumed, all fours blue LEDs lit) which was a nice plus. The packaging was extremely eco-friendly all being made of paper and a recyclable plastic bag that protected the actual Astro E5 battery unit. In the box was the Astro E5 power pack, a Micro-USB cable and a soft case to protect the glossy battery case.

Feature wise, it's a very large capacity battery pack. Managed to charge my iPad twice over from ~20% and Lumia 1020 from 0% all on a single charge. Extremely fast too, definitely no complaints with the PowerIQ technology in this. However, I have come across with an issue using thrid-party lightning cables with the pack; both ends of the cable got extremely hot and continued to drain power after the iPad was unplugged therefore running the battery pack to 0% without realizing. I have had no issues when using the official/genuine lightning cable though, so recommend using this. Charge time for the power pack itself was just over 6 hours from 0% (using a 2.1a charger), which is very acceptable considering the capacity.

Feature wise, I mentioned PowerIQ. This is the technology that Anker includes with this pack that will automatically shut off the charging process when the plugged-in device reaches 100% charge, to stop wastage in the Astro E5. Other features include a pretty useful white LED located between the USB ports for seeing the dark. A nice bonus indeedy! You can press the power button on the side of the Astro E5 to enable the battery pack/see what charge is remaining, holding down down this button for 5 seconds will enable the LED mentioned above.

A great product, does exactly what it says on the can. However, is it just me or does anybody else have a problem keeping the power usb plug in? If you knock mine even a fraction, out it pops and stops charging. Apart from that minor design defect, a 5-star product!

Update: having posted this, I remembered that the device came with a USB lead. On checking this, I noticed that the plug was significantly longer than my standard, Samsung, one. When I inserted this lead, it made a considerably firmer and more secure contact. Rating amended accordingly, now I need to remember to only use this lead to charge up the device.

Great customer service from the manufacturer, too!

Colour Name: 16000mAh (Black) Verified Purchase
Works well - I've charged several devices including an iPad and Nexus 7. Seems to charge at least as fast as using the original device mains chargers. Based on initial tests, looks like you can get roughly two full charges of a tablet, or around 6-8 phone charges.

Due to the capacity, charging this to max capacity takes quite a few hours - forget about charging to full from a phone charger during your lunch break. If you're depending on this for power, I'd charge it up over night before heading out.

It's quite heavy and a bit smaller than a glasses case.

I like the fact it will adjust output so you can plug into either of the USB ports regardless of device.

The four LEDs are a bit vague indicating charging status - I think a device like this would benefit from a more accurate read-out (more LEDs or percentage based).

There is no charger supplied, and this is best charged with a higher output charger (2+ amps), the sort of thing supplied with an iPad or Nexus 7 tablet, rather than the lower output ones supplied with phones.

Overall it's very good for the price.

Less than a month after using this, it has stopped worked. This is so ridiculous.
It simply won't charge up when connected to the power source and won't charge my phone either.
I now have a big useless device that I can't return

Wow, this product was definitely worth the money. It comes in its own pouch and includes a lead, it has 2 output usb ports and 1 input port and its a torch too (although didnt use it as that). I took it to glastonbury was there for 5 days and it charged mine and my friends phones multiple times, my camera and ran speakers for music also! Ive brought it back home and its still got charge on it!
