If you have already gone through the detailed review of top ten portable chargers in Inidia, that are already covered in much depth, at the home page of Powerbanky, then possibly you might have gotten the fact that, most of the power banks discussed there was basically available popularly in Indian Sub-Continent. So, listening to the demands of the readers of Powerbanky, we have come with the thought to come up with another extensive battery pack list but this time, we would keep the locus strictly to the US and Europe market. So, before any other word as the preface let’s straight jump into the round up of portable charger.
A little note to those who might be wondering what all about the talks are going on and are totally noob about portable battery packs, it is required to give a direction here to this post as here you can get all what you might have as the query regarding portable power banks or even to this power bank FAQ, which would be answering the points before they turn up in your mind.
Ok, let’s move on to the reviews. Below we have listed 7 of the best power banks from each category. They were selected because they are suitable for very specific needs. We start with the best overall performer then the best outdoor power bank and we will be seeing a number of them in this category and at the last we decided to list the best in terms of cheapest external battery charger that you can get over on-line market.
1. Anker Astro E7 25600 mAh Review
The Anker Astro E7 is an attractive unit, with a sleek black case. The size is really impressive – the E7 is smaller than an iPad and fits comfortably enough inside your pocket.
- Great Power
- A Little Heavy
Beneath the shiny surface lies a powerful array of batteries, containing a huge 25600mAh of capacity. This is enough energy to charge an iPhone 7 times over.
While this is undoubtedly impressive, the E7 is not just about raw power. It contains an ingenious new technology called “PowerIQ amp-adjustment“. What PowerIQ does is it detects the type of device attached and modifies the flow of power. This way it can charge the device as fast as possible.
Different devices have different optimal charge rates – some can suck up power faster than others. It’s dangerous to try and overload a device which charges slowly, which is why lots of generic chargers are designed to charge all devices slowly.
Of course, if your device can take the power quickly, you don’t want to waste time waiting.
That’s why the “PowerIQ amp-adjustment” feature is such a great time saver.
The E7 has several ports to allow it to work with a variety of different devices. It can work with iPhones, Androids, tablets, and laptops. In fact, any device which uses a standard connection (such as USB) will be able to charge from this awesome power bank.
Of course, reliability is as important as clever features. Reliability has a lot to do with the materials and components used in a product. Anker E7 is built with premium LG battery cells and sturdy materials, which means it will stand up well to frequent usage.
To see how well the E7 performed over time, I checked out some customer reviews.
The E7 is a very popular product, and this means that there are literally hundreds of customer reviews online. The vast majority of these reviews are very positive.
In fact, most people report that the E7 performed better than the manufacturer’s claims. For instance, one owner said that it was able to fully charge his iPhone 5 9 times with power left over, whereas Anker only claims it can charge the iPhone 7 times.
It looks like Anker is in the habit of delivering more than was promised, which is good news for us!
2. Gorilla Outdoor 10400 mAh Power Bank Review
The outdoors environment is full of challenges to any battery device. Things like water, sharp jolts and bumps can all cause problems to a battery.
- Water Resistant
- Chock Proof
The Gorilla gear is designed to laugh in the face of challenges such as these. It is built with a rugged, shockproof construction that is water resistant and ready for almost anything the great outdoors has to throw at it.
Note that’s water resistant, not waterproof! So if it does fall into the water, get it out quick and it will be OK. Don’t take it diving!
The casing has ridges on the side to make it easier to hold even when wet.
It has dual USB ports, so it can charge 2 devices at the same time. It has “universal compatibility”, which means it is able to provide power at the right voltage to a very broad range of different devices.
The manufacturers are serious when they say this device will stand up to punishment – they back this up with a full lifetime guarantee.
Their blurb recommends this product for extreme sports and outdoors activities, and owners have taken this to heart.
Reading the customer reviews, I see many reports about this gadget standing up to real punishment, such as Kayaking, climbing, and so on.
Of course, if you are planning such activities, you need to make sure your phone and tablet can take the same type of punishment!
There are a couple of little glitches to report. They aren’t deal breakers, but they are worth keeping in mind.
Firstly, some users have reported that the Gorilla Gear sometimes switches itself off in the first few minutes of charging. If you press the power button, it will start again and keep charging to the end.
The other glitch concerned the cable having to be held at exactly the right angle in order to charge the device. I could only find one report of this fault, and it could have been caused by a kink in the wire. However, I’m letting you know just in case it happens to you.
Of course, the manufacturer warranty covers defects, so you should be able to get it replaced without trouble if you experience any issues.
3. Kmashi 10000 mAh MP816 Charger Review
While it’s not as pretty as the Anker Astro E7, the KMASHI is no ugly duckling. Its black case has a gloss finish, and a neon pink side (this looks cool, but it may not suit everyone’s taste).
- Fast Charging
- High Capacity
- Problem with Charging Some Devices
The device is compact and pocket-sized. It’s a little smaller than a Galaxy Note.
This power bank has a capacity of 10000 mAh, making it the least powerful option in this lineup. However, this is more than enough energy to fully charge most phones a couple of times, and can help to keep a larger device ticking over even if it can’t fully charge it.
As an emergency backup, this should be enough for most people.
The MP816 is designed to charge quickly with a 5-volt charger.
It has 2 USB outputs, so you can charge 2 devices at the same time.
There are thousands of customer reviews, and the majority of them are positive.
Some customers complaining that the capacity is not as high as competing brands. However, the MP816 is a lot cheaper than many competitors, so this must be factored in.
A tiny minority of users (like 1%) reported that their power bank has stopped working after a few weeks. The device is covered by warranty, so in these cases a customer should return the product to get a replacement.
It only seemed to have happened to a few customers, so I think this was probably a faulty batch.
The main strength of the MP816 is that it’s so much cheaper than its competitors. It provides respectable performance at an amazing price, but it’s obviously not the best portable charger for heavy usage or extreme conditions.
4. Vinsic 20000 mAh Ultra-slim Power Bank
Don’t let the slim form factor fool you. The Vinsic 20000mAh Ultra-slim Power Bank provides an impressive amount of juice in such a slim build. You can easily lug this thing around in a purse or a bag. Also, the device has two USB ports which means that you can charge two devices simultaneously.
The best thing of all? The Vinsic has all sorts of protection against overcharging, overdischarging, over-voltage and other circuit issues. Not only does this thing power up your device, it also helps make it last longer too. You can’t get any better than that.
5. ALLPOWERS™ 3nd Gen 15600 mAh 3.5A Output Power Bank
An amperage rating of 3.5A means that the ALLPOWERS 3nd Gen Portable charger with a capacity of 15600 mAh can handle the most power intensive of mobile devices (i.e iPad air and other similar tablets). Aside from its impressive charging capabilities, the unit has AllPower’s patented iPower Fast Charging technology which automatically adjusts the current voltage to provided maximum juice output to your device.
This power bank is compatible with most smartphones and tablets, as well as portable game consoles (PSPs), digital cameras, GPS units, and bluetooth speakers.

6. RAVPower Xtreme Capacity 18200mAh Battery Pack Review
Unlike most external chargers, the RAVPower Xtreme Capacity 18200 mAh earns the distinction of being able to charge three devices all at once. You get 1.0 A and 1.5A ports for smaller devices like smartphones, and another 2.4A output for tablets.
The brand’s patented iSmart technology also ensures that each of the devices connected to the unit is provided enough power while charging at full speed. And unlike other brands, the RAVPower actually has an LCD screen instead of the usual LED lights so that you can easily see how much power you have left.

7. EasyAcc® 20000mAh Dual USB Power Bank Review
20000 mAh is a lot of juice. The EasyAcc® 20000 mAh Dual USB Power Bank can easily power up an iPhone nearly ten times or an iPad air twice. With an output of two USB ports, you can easily charge two devices simultaneously. Another great thing is that the unit has a clear digital LED display (not LED lights) that displays the remaining battery as a percentage– which means no more guesswork when you want to compute how much power you have left!
The output ports are compatible with a wide range of mobile devices like Bluetooth speakers, PSPs, headphones, and even Google Glass.

How to Make a decision
So far, we have shown you our top 7 picks, but we’ve really just scratched the surface.
How do you look beyond the power bank review and decide which one to choose?
There are several things you need to weigh up to make a decision.
Firstly, how often will you be using the power bank? Some users need it purely as an emergency backup. They don’t know when they’ll use it, they just want to be covered if they should forget to charge their phone or another device.
On the other end of the spectrum is the owner who plans to use the power bank heavily over several days. For instance, if you are planning a camping trip, you will need to take a high-capacity power bank, or maybe even more than one.
Another thing to consider is the requirements of your devices. Most phones, tablets and other items have a power rating in mAH. Now you know what these figures are for!
It’s worth pointing out that not all of the energy in your power bank will be available to your mobile devices. All electronics equipment suffers from some degree of inefficiency, which means that some of the energy will be lost as heat. On average, this lost energy accounts for about 30%.
The lesson is to get more capacity than you will need.
There are other practical considerations to look at. Size and weight can be important. If you are going to carry the power bank in your pocket, you don’t want it to be too heavy!
Some people buy the highest capacity power bank their money will buy. But more capacity means more weight, so think about what your requirements really are.
Appearance is an important factor, too. Why carry around an ugly power bank when there are so many sleek and attractive options at the same price Point?
The speed of charging is important. Some power banks charge with a very low current, which means they charging your device slowly. The Anker Astro E7 has the advantage of intelligently selecting the best current to charge your device fast and safely.
Not all features are vital. For example, some people want a portable battery charger that can provide charge while it’s being charged. That seems a bit wasteful to me, as you could charge your devices directly – remember, wasted energy contributes to global warming!
So consider whether additional features are really useful before you spend more money for them.
What kind of connectors does the power bank support? Almost every power bank provides standard USB connectors, but some devices have special requirements. Do you need extra sockets?
How many devices do you need to charge at the same time?
Does the manufacturer offer a warranty which covers defects and guarantees a minimum battery lifespan?

Making the right choice means understanding your requirements and weighing up your options. We’re going to make it easier for you by narrowing the field, and selecting the best options from the thousands of power banks out there. But you still need to know what your own requirements are when you read a Genuine Power Bank Review, so you can choose the right option for you.
