This product arrived last week and I have purchased it to get me through the Glastonbury Festival in the summer.

I have been running an experiment on my iPhone 4 since last Monday afternoon charging my device with nothing other than than this product and it works a treat. Today (Sunday) was the sixth day and it finally ran out of power.

During the last 6 days I have charged my device 9 times with varying degrees of battery power left in the phone. The table below shows (Start of charge battery %, End of charge battery %, Total charge % & No. of powers bars left on device ranging from 1-4)

38% 99% 61% 4 bars
41% 97% 56% 4 bars
0% 83% 83% 3 bars
17% 97% 80% 3 bars
18% 96% 78% 2 bars
15% 97% 82% 2 bars
32% 95% 63% 1 bar
44% 100% 56% 1 bar
24% 66% 42% 0 bar
Total charge 601%

It took approximately 90 mins to do a full charge.

Overall a very good product and should do me nicely at Glastonbury.

First off - I apologise if any of this is patronising; it will likely contain points which may be obvious but I feel it's right to raise them to make sure people purchase the right tool for the right job. I purchased this unit to replace a failed Anker 8000mAh unit I purchased last year.

The version I'm reviewing is the 12000mAh version. I can't speak for the other capacities just yet (but I will be ordering one soon).

This unit is great, and it has come in handy all ready. Some points follow which may be good or bad for your usage. Either way, they should be handy if you're considering this...

This thing has so far charged everything I've thrown at it. A 2013 Nexus 7, two Kindles, a HTC One X and an old HTC phone. You get a couple of leads with it and a bunch of converters to make up iPhone/Nokia leads, etc. However, you've probably got a bunch of USB leads lying around that will work just as well.

It charges through its Micro USB port on the side. Personally this was one of the selling points. When I travel I like to carry as little as possible. Most things I take charge off Micro USB, so the lead will not be a problem. Then, I only need to take one USB wall charger.

That's if it needs recharging whilst you're away. I took this to keep phones, tablets and sat-navs fully charged when we were travelling without power. At our destination it had hardly made a dent in its capacity. I dare say that if you were taking a phone on a camping trip it would keep it powered up for your duration.

Beware that - although it charges up over Micro USB - you can't just plug it into your laptop's USB port and fill it up. It will need a decent wall charger and a fair bit of time to fill it up.

I bought this knowing I could use it to recharge phones and the like - but my hope was to be able to make a Raspberry Pi completely portable. This powerpack will run a lilliput 10 inch screen happily - you just need the right cable, which I bought separately. As it has 4 USB slots, I can also attach the Pi itself. A small wireless keyboard and wired or witeless mouse, a little velcro and a 5mm A3 piece of plastic and I can get the whole lot as a portable unit.

Excellent.

----------------------------------------------
***DISCLOSURE***
'EasyAcc' provided this item free of charge for me to test and evaluate. In exchange, I agreed to provide an honest review detailing my thoughts. This is said review.
----------------------------------------------

This product has a black and silver plastic exterior. It has a button on the side that will cause the lights to come life, indicating how much battery power remains. This button can also be used to start/stop charging when something is plugged in. It has four slots to charge devices. Each slot is 5V, and each one is rated at a different amperage. You have 0.5A, 1.3A, 1.0A and 2.1A. This is useful if you are charging different devices that can handle more power. This power bank is changed via a micro USB cable and doesn't take very long at all. It is supplied with a carrying case for the power bank. This is a little confusing as the device doesn't actually fit fully within the case. My only thought is that this was deliberate, to allow access to the four ports whilst the power bank was in the case. In my opinion this was a mistake, as the materials of the case and the power bank together create very little friction, resulting in the device simply falling out. Bottom line, don't use it to carry the power bank around.

In the couple of weeks I've had this product, I've come to the conclusion that it can charge an iPhone 5/5S around 5-7 times from empty(ish) to full- which is more than enough for most people. It charges the iPhone at the fastest that is possible since it has three ports that push out equal to or over 1.0A. The power indicator lights are extremely handy and let you know when it's time to recharge it.

Nowadays we have so many gadgets and they all have so much power and so many functions that the chances are that unless you're near a charging outlet often, something will be running flat. Whilst phone batteries are usually in the region of 1500 to 2500 mAh, I wanted something that would charge a few gadgets and something that would do it quickly.

This power pack has a huge capacity of 12000mAh, meaning that in theory, you could charge a mobile phone from empty to full approximately 6 times. In practice, nothing is 100% efficient and when it comes to power packs, the actual capacity is also often less than what is stated. Despite this, I have achieved 5 full charges of my Galaxy S3 from my power pack.

Another thing I like about this is the fact that over time very little capacity is discharged. Whilst it's best to fully charge it before going away to rely on it, if you have forgotten, this power pack seems to hold its charge well.

It charges quickly with USB ports of various Amperages.

I would say that if you're expecting it to be nice and light and small you're in for a surprise but then that's a physical and chemical restraint based on the properties of matter and a matter best discussed somewhere other than an Amazon review.

If you want piece of mind, you can't go wrong with this.
