Tired of your phone battery dying all the time? Worry no more, power banks are the new buzz which are keeping our phones alive for longer!
What is a power bank?
As if to answer the needs of millions of smartphone users, power banks are the latest “hot cakes” on the electronics market.
Simply put, a power bank is a power storage device with which you can charge your phone. It also boasts portability, your phone could charge with the power bank right beside it, in your pocket. The manufacturers add a separate smaller cable for charging your phone, though any stock USB cable will do.
Before use, you need to charge the power bank by reversing the cable ends, preferably with a stock mobile phone charger.
Measuring a power banks worth
To help you in an endeavor of searching power banks online or on the market, we’ll use some common battery capacity measuring jargon. A power bank’s capacity is usually measured and advertised in mAh-milliampere per hour.
To get a basic notion of how much it is worth, compare the capacity of a power bank to the capacity of your own mobile phone. Simple math will tell you how many times a fully charged power bank can charge your phone.
How to select the best power bank
This is a resounding question asked by people all over the Internet: What should I keep in mind while buying the best power bank? Is taking a note of the mAh enough?
If you don’t expect much for the price you’re paying, making a note of the mAh is enough. However, if you want more bang for your buck, here’s what you should keep in mind:
- Try to determine the efficiency of a power bank. The efficiency of a power bank describes how much of the charge in the power bank actually goes into the phone without any loss. Calculate the “real capacity” of your power bank by applying basic percentage mathematics
- Make sure your power bank has overcharge protection. In cheaper power banks that lack this feature, a common cause of the device breaking down is overcharging. If you’re going for a quality power bank, this feature is a must have
- Lastly, the color, size, and shape should be taken into consideration. Try avoiding bulky power banks as you can most probably find the same quality in a smaller size under a different brand
The 10 best power banks of 2017
If you’re ready to shell out decent money, you’ll find an unbelievable number of power banks on the market. It’s hard to choose the better product among two when they both boast about the same qualities. We’re here to help you find the one you need with a list of the top 10 power banks for 2017.
|Power Bank||Battery Capacity||Weight|
|Anker PowerCore+ |
|Kmashi MP816||10,000mAh||9.79 ounces|
|Ravpower Ace |
|Zendure A8||26,800mAh||20.49 ounces|
|Vinsic Ultra Slim||20,000mAh||1.1 pounds|
|EasyAcc Monster ||20,000mAh||16 ounces|
|Jackery Giant+ ||12,000mAh||10.4 ounces|
|Polanfo Bank||12,000mAh||9.4 ounces|
|Anker PowerCore 10000 |
|Zendure A2||6,700mAh||4.8 ounces|
1. – Anker PowerCore+ 20100eas – Best Power Bank 2017
Anker is already a well-established company where power banks are concerned. A dozen other flagship power banks from the same company could have made this list. However, the Anker Powercore tends to shine a little brighter.
The word that sets this power bank apart from its brothers is speed. It has two USB ports and people might mistake one for inlet and other as an outlet. While technically, they are not wrong, the outlet port can be reversed too, so you can double the speed at which your phone charges while also doubling the rate at which it charges from an AC inlet. Set at 15 W, the charging speed of this power bank is among the best.
With a beastly capacity of 13065 mAh, Anker promises that you can charge your power bank in eight hours, which is a pittance compared to the capacity. While there is no Qualcomm Quick Charge support (a quick charging utility), the company promises that the inbuilt speeds are as fast as fast can be.
You can even charge laptops and MacBooks from this power bank, though there might be a few technical difficulties along the way.
During tests, the Anker PowerCore charged an iPhone 6 from zero to full at least seven times. You need not worry about higher capacity smartphones, such as a Nexus P6, as it can reliably charge batteries of 3000mAh + at least three times.
However, efficiency is where this power bank is not on the bright side. The power bank delivers only 60-70 percent, which though decent, falls short of other power banks in the same price range.
Other perks include the power bank being waterproof, and the build quality being excellent. So you need not worry about dropping it accidentally in water. Also, the build quality, while not the sleekest among all, is certainly slim enough to fit in your pocket, though a cover is also provided as an accessory. You also receive an 18-month warranty.
2.- Kmashi 10000 mAh – Best Budget Power Bank 2017
It is hard to define your power consumption needs for your mobile. There are power banks as huge as 20000 mAh, like the one we reviewed before, and there are power banks as small as 2000 mAh. This power bank hits the sweet spot between the extremely high and extremely low.
The Kmashi 10000 mAh charger fits all your charging needs. So if you’re planning to buy a power bank to take on a long trip for example, but don’t want to carry a lot of bulk with you, this is the smartest option.
The Kmashi 10000 charger is designed to juice your phone 4 or 5 times at the most. It also does that extremely quickly, so you don’t have to fret with cables for a long time. It has two USB ports on its front face, and allows for an astonishing 80 percent efficiency.
The charger has a well-built, sturdy body encompassed with a satisfactory design. With a beautiful red strip running across two black faces, the charger, though not being the best of designs, will still not look bulky or out of place.
The Kmashi 10000 mAh charger is designed with Apple smartphones in mind. This means that you could buy this durable power bank once, and use it with any generation of iPhone which will ever be manufactured. No software upgrades within the iPhone will hamper the capabilities of this charger.
Efficiency is nothing short of brilliant. Sitting at around 80 percent, the efficiency of this power bank beats a lot of biggies in the power bank market.
This power bank applies the four LED battery indication method, which is just acceptable, but loses its value in a higher capacity charger like this one.
Also, it doesn’t support the latest Quick charge and USB-C technologies, but the stock charging speed is quick enough on its own. It is recommended to use a 5V adapter to get an appreciable charging speed; this puts the estimated time it takes to charge at around 6 to 7 hours. However, charging your phone might take only up to 1.5 hours or slightly more. It also features overcharge protection.
3. – Ravpower Ace 22,000 mAh – Best High Capacity Power Bank
With the Ravpower Ace which allows three phones to be connected at once to an external battery of massive capacity, you can keep your whole family entertained during long trips.
Three phones will charge independently and reliably, though connecting more will obviously cause the battery to drain faster. That shouldn’t be a problem, as 22,000 is humongous when compared to most power banks.
The areas which have been compromised to provide all the above features are weight and looks. Though an attempt to make this power bank look good was evidently made, the manufacturers could not escape the inevitability of making a large and less intricate power bank.
However, if looks are not much of a selling point to you, then this is the one power bank you’ve been looking for all of your life.
Also, the whole 22,000 mAh capacity of this power bank refills in a time of just 10-11 hours. That means you’ll never run out of juice for days together just by leaving it to charge overnight.
The weight also might be an issue to some people. Weighing a massive 406g, this is the one power bank that cannot boast of being portable in your pocket.
Again, the four LED method has been applied to indicate the amount of charging present. This is one negative point because the four LEDs lose their comprehensiveness once the capacity of the battery goes beyond 20,000 mAh. This might bug some people, but it might not be such a big deal after all.
The output is extremely powerful at 5V AND 29V. It also makes use of technologies such as iSmart and supports pass-through charging. It comes with two micro USB cables and a carry case as accessories. The warranty is set at 18 months which is huge, just like the power bank itself. Keeping all of its pluses in mind, we’re sure you won’t believe the price.
For all that it provides, the price of this power bank is unbelievably low. If looks and weight aren’t a problem for you, and having to carry a huge power bank in a case isn’t much of an inconvenience to you, this is the power bank you should go to. This power bank is a must buy for families and if you’re planning to go on long trips.
4. – Zendure A8 QC Power Bank – Best Designed Power Bank
The Zendure A8 QC packs a massive 26,800 mAh of capacity; you’ll never run out of battery for ages to come. With its three USB Q3 ports and a QuickCharge port, you can expect blazing charging speeds, both while charging your mobile phone and while charging the power bank itself.
The Zendure A8 QC comes in an elegant silver color; the power bank looks like a beautiful little money suitcase, great to look at but incredibly bulky at the same time. The whole package looks more sophisticated with an LCD screen located at the front end.
Due to the Qualcomm QuickCharge utility, this 26,800 mAh beast can be tamed within a paltry 10 hours. However, while performance at charging one phone is really great, multiple phones connected to this power bank do not gel with each other well. Connecting more phones will cause the speed to split between the phones. This is the selling point of the Ravpower Ace over the Zendure A8.
Despite the above drawback, the Zendure A8 is nothing short of awesome. The device is capable of powering and repowering a standard iPhone 6s over 12 times, and phones of greater capacity at least nine times or more; hence, it is a good pair with an iPhone. The device also supports pass-through charging so you can charge both your power bank and your mobile phone at the same time.
The device boasts of 90 percent efficiency, so very less power is wasted as heat or losses. The power bank also features an LCD screen so you can see the amount of charge present in your power bank much more reliably than the four LED indicators.
The bulkiness might be a letdown for some people. It weighs a massive 481g so you shouldn’t expect to be carrying this device in your pocket. Also, we have to warn you, not everyone finds the design appealing, so take a look before jumping to buy it.
This charger is so sleek. It gives serious competition to your own mobile phone where fitting into small spaces is concerned; this means you can fit both your phone and charger in the same pocket.
It comes in a variety of colors, and with the amazing body design this power bank has, you will be left wondering how someone could fit 20000 mAh into such a sleek power bank. The body looks wholly metallic, and it shines and reflects color which makes it a treat for the eyes. The actual material used is plastic with aluminum alloy.
Unfortunately, the device does not support pass-through charging and Qualcomm Quick Charge, though we weren’t expecting those features for the price.
A lot of effort has gone into adding other quality features to this power bank. It supports overcharge, over discharge, over voltage, over current and short circuit protection.
The one feature that separates it from all the power banks we’ve reviewed so far is that this power bank has a built-in flashlight. How about that, a 20000 mAh power bank that doubles up as a flashlight! With the juice it contains, you can be sure that you can leave the flashlight on for hours and the charge won’t run out.
This power bank, keeping in league with its “monster” name, allows for four USB outlet ports. With a sleek varnished body with an orange strip on the side, this power bank is similar in design to the Kmashi 10000 power bank, all the while allowing for twice as much capacity.
The EasyAcc Monster allows for pass-through charging. It packs for a moderately good power output of 4.8W, which is good for power banks in this price range. It also has this amazing feature, by which the portable charger changes its output to be optimal for the smartphone it is connected to.
Unfortunately, the charger doesn’t support Qualcomm Quick charge. However, it does promise to fill itself up in only 6 hours. With four USB output ports available, you can charge four devices at the same time, though possibly you’ll be compromising on charging speed.
Like most other power banks, this power bank employs the four LED charging indicator system.
The Jackery Giant+ Premium power bank is the definition of balance between power and style. We are sure no characteristic of this will disappoint anyone, and that is the reason why the product makes our list.
The Jackery Giant+ power bank has the backing of the trusted company Panasonic behind it. You can smell the perfection of its manufacturer in the power banks well-rounded edges and sleek, smartphone-like design.
Housing a powerful 5V/3.1A micro USB output, the Jackery Giant+ Premium charges your iPhone battery 4-5 times. The device houses two USB outlets so you can charge two devices at the same time.
The Jackery Giant+ boasts many layers of protection to protect the powerful battery resting inside its intricate design. The smart charger also allows for pass-through charging and has an auto-on feature.
It should be noted that this is the only power bank of its kind where an enormous capacity of 10000 mAh is packed into small dimensions of 91mm x 60.4mm x 22mm. The power bank can charge a standard Samsung S6 twice and still have more than half of its battery left! This means that an iPhone can be charged at least five times.
The power bank comes with a flat white USB to micro USB cable. For a power bank which is in between big and small with respect to size, it is tough to either justify or deny the manufacturer’s decision of not supplying a carrying case. Though for us, we feel that it is sleek enough to fit in everyone’s pocket.
Again, like most others, this power bank uses the LED display method, which is a little lacking, though the display method is comprehensive enough for a 12000 mAh lithium ion battery. The beauty and price of the device make-up for its lack of quick-charging capabilities.
The Polanfo 12000 mAh power bank is the definition of making otherwise bulky stuff beautiful. This design is sleeker than the Vinsic power bank we discussed earlier. Hence, it sets a new bar where portability is concerned. With a jet black body with a white face, keeping this power bank looks as if you’re carrying one of those stylish and posh mini diaries with you.
It is very light, and you won’t feel its presence in your pocket. It employs the same sleek manufacturing standards of Apple products, consistently using materials such as anodized aluminum alloy.
This power bank has a cool looking LED finishing its modern look.
Though you might find other power banks that work slightly better than the Polanfo 12000, this power bank is still massively powerful. The emphasis in the above sentence is on “slightly” and we mean slight in the strongest of terms. It packs a decent input of 5V and an output of 2.1A and 1A. This might not be a cause of concern for a lot of customers.
The drawbacks are a pittance compared to what it has to offer. While it does not support Qualcomm Quick charge yet, it employs smart charge, rarely found in other flagships. This means it charges phones via a “brain” and optimizes its output for different phones while saving power.
The Polanfo 12000 power bank is an extremely powerful and high capacity power bank wrapped in one of the most beautiful of designs you can find. Definitely for people who wanted to take their coolness level one inch farther. Very stylish and suitable for students.
Leaving its 20000 mAh counterparts in the behinds of this list, you might wonder why the Anker Powercore makes it here. Well, it’s because unlike its 20000 mAh battery that tries to solely focus on capacity, this power bank is much better designed and feature heavy. Read on to find out how.
We’ll give it to you straight. The design isn’t as beautiful as its counterpart, the Polanfo 10000 mAh battery charger. However, the features are what you are paying for here.
While being a little huge and bulky, the Anker Powercore is still very pocketable. It consists of sturdy a metallic or aluminum body over two white plates at the edges, so you can be sure the battery is protected from rough usage.
Also, the power bank has rounded edges, so you shouldn’t worry much about it falling on an edge and damaging an edge. Its rigid, tough and sturdy design might make its looks feel a little bland, though the device isn’t really boasting its looks.
The device also supports an auto-on feature, which lets you start charging by simply plugging your device in instead of taking your power bank out of your preferred storage place and fiddling with the controls.
The power bank houses a single USB port, and a single micro-USB port, which is a little lackluster to be on a top list, but is still pretty standard.
This power bank, as if to compensate for its lack of design, is much more feature heavy compared to others in its league.
For its amazingly low price, it offers Qualcomm Quick charge support and smart charging capabilities. The quick charging nature of this device puts its charging to a very speedy time of 6 to 7 hours.
Most Android phones have rolled out support for Qualcomm Quick charge 3.0, the very utility this power bank employs. Unfortunately, the makers of this power bank themselves have disabled pass-through charging, in an attempt to protect its battery. This is a big downgrade from other power banks which allow for this feature in the same price range.
10. – Zendure A2 – Best Fastest Power Bank
Described by PC Advisor, a famous online electronics magazine, as the ultimate sweet spot between price, capacity, and portability, the Zendure A2 is set to prove the magazine right in every way possible.
The body comprises of a comfy plastic which feels as good as any other material you may want your power bank to be in. It looks a little rugged and has a rugged lining on its faces too, but the looks and feel of the Zendure A2 are still incredible.
Housing a powerful enough battery of capacity 6400 mAh, this power bank has the distinction of being a jack of all trades. The newest versions boast an improved battery capacity of 6700 mAh.
The body houses a simple USB output of current standards 2.1 A and a micro-USB input of 1.5A. This makes for the nature of this power bank to be described as simple beauty.
You can also charge multiple devices at the same time via this power bank, but the single inlet-outlet system limits your options. However, this is not a power bank designed to charge multiple devices; it is for day to day rough use.
The battery housed in this power bank boasts of charging retention of up to 6 months. So even if you throw your power bank in a bag and forget all about it, it’ll still get you out of sticky charging situations in time of need.
Up until now, we’ve seen how power bank manufacturers had to compromise in one arrear or the other if they were planning to focus on pushing a single characteristic of their product over the top. But this power bank is the holy trinity—perfect looks, perfect features at the perfect price.
This power bank attempts to push the 5000 mAh limit other power banks put themselves to. It also houses a four LED charging display system, which though falling a little low, is still a very comprehensible scale for a 6000 mAh battery. With how Zendure keeps updating their products, you can expect them to release a greater capacity version in the near future.
Final words – Wrapping it up
The list, though extensive, is not exhaustive. There are at least a dozen power banks out there that might equally compare to those on our list. We just wanted to show you what we think are the best ones.
We hope you’ll keep your battery needs and your smartphone in mind before making a purchase. After all, power banks are something which will stick with you for the same duration as your smartphone.
