The Ultimate Buying Guide to Mobile Power Bank Designed for Use on the Go.
Power Bank comes with different names, battery packs, portable chargers, fuel banks, pocket power cells and back-up charging devices to name just few. But whatever you call them, they all do the same thing: CHARGE YOUR PHONE OR TABLET WITHOUT NEEDING A POWER OUTLET.
Power Bank, comes in all shapes and sizes, smaller sizes for an essential smartphone boost in your pocket, or bigger sizes for multiple charges or to charge a tablet.
Meanwhile, you’ll notice some power banks with cables included, or some with multiple ports to charge more than one device at a time.
Q1: Why to choose power bank for your phone and tablet?
Mobile Devices like smartphones and tablets make life so much easier. That is , until they run our of battery power when there’s nowhere to plug in. 
Q2: What you will benefit while choosing a perfect power bank for your phone?
Well, a lightweight power bank you can carry anywhere. Simply charge it up at home, throw it in your bag or your pocket, and connect it to your phone whenever it needs a quick battery boost. You’ll never suffer from “low battery anxiety” again. 
Q3: How to choose power bank for your phone/tablet?
How to choose power bank for your phone and tablet? Surely, it could be easy for you as you could just follow these tips below one by one; while it would be a little hard as you have to read and check the tips carefully, covering up to eight aspects in total, the size/capacity of power bank, power output, number of USB ports, cables included, power input, safety, quality and certification.
Let’s start by choosing the size of your power bank.
This is not about which one will fit in your pocket or your purse. The size of the battery is about the power inside. Most power banks will feature a number on the front that tells you the number of mAh or “milliamp-hour”.
Common sizes range from 2,000mAh up to 10,000mAh or even 26,000mAh. Bigger numbers mean more power and more recharges for your smartphone, or charging for bigger devices that need more power, like a tablet.
We’ve used smartphones and tablets to compare battery sizes, but most power banks will charge any device that charges via USB, such as a GoPro camera, Kindle reader or Bluetooth headset. Bigger devices that draw more power will need bigger batteries – more mAh – to charge them fully.
Then, we should consider POWER OUTPUT, a key point that’s to ensure fast charging for your phone/tablet.
Technically the standard USB port on your power bank will fit any standard USB cable. However, the amount of power it can provide may vary.
Question: How many times can a Power Bank 20,000mAh fully charge your phone?
Thirdly, it falls on NUMBER OF USB PORTS, a mattter of how many devices you need to charge.
Generally, bigger batteries with more mAh, sometimes have more than one USB port. If so, that can be useful to charge two smartphones at the same time – maybe to give a battery boost to a friend.
Or you can charge your smartphone and your GoPro at the same time.
Or your smartphone and your Bluetooth headset.
Or even a smartphone and a tablet, if you choose a battery with enough mAh to provide all that power.
With multiple ports, simultaneous charging is super-easy.
Fourth: your power bank will come with a cable.
A cable to charge the battery: YES
Every power bank should come with one cable (usually a standrad USB to Micro-USB cable) to charge the power bank itself, which you use to connect the power bank input port (usually Micro-USB) to a standard USB wall charger.
A cable to charge your phone/tablet: MAYBE
If your phone or tablet connects via Micro-USB, you can use the supplied cable to charge it.
If your phone or tablet connects via a Lightning or USB-C connector, you will need to use an additional cable to charge it. Some power banks come with multiple cables and you could check the packaging to see what’s included.
Some power banks provide cables that are detachable, which makes it easy to switch between cables for your iPad, your Samsung phone, your Kindle or another device.
Some have cables that’re hard-wired to the battery that they cannot be detached, making them easier to find in a low battery emergency, but may make them less versatile overall.
Some even have clever storage solution: a detachable cable you can switch out for other cable, plus a way to keep the cable close so it’s always close at hand.
Fifthly, it’s about charging the power bank itself.
Unfortunately, no power bank has been invented that magically recharges itself when it’s empty. But on the whole, they are pretty simple to charge: plug the supplied cable into the input port on the power bank and a standard USB on the other end into a wall charger or other power source.
Power Bank input ranges from 1Amp up to 3Amps(short for ampere and it’s a unit of current) or even higher with type-c input. Put simply, the bigger the input number, the faster it will recharge.
Some power banks have an LED indicator, which tells you how much power the power bank has left and on the other side will tell you when you need to recharge the battery.
What’s more? Here’s something about how to choose a safe power bank.
It’s easy to avoid counterfeit and dangerous ones by following these simple steps:
Register Your Device some power banks require you to register your purchase, by providing the serial number either online or via a helpline. This is a good way to activate your returns policy and to ensure your product is not a counterfeit.
Check the Warranty manufacturer, country of origin and the type of battery may mean differences in the type or duration of the warranty. If you are unsure, check the small print on the package or the instructions provided.
Something else? Surely. The Importance of Quality.
Safe power banks should have undergone the following testing.
Efficiency more efficient power bank is, a lower operating temperature it will have, which wastes less energy for a longer life expectancy.
Over Current Protection it prevents too much power going into the battery pack and the power going out to the connected equipment, protecting the delicate circuitry of both devices.
Over Voltage Protection it protects both the power bank and the connected device by keeping the voltage within recommended safety parameters to avoid damage.
Over Discharge/Charge Protection some power banks consistently monitor charge states to prevent this from happening.
Heat Tests at Extreme Temperatures While using batteries in extreme temperatures isn’t advised anywhere.
Last but least, it’s CERTIFICATION.
These logos or marks, usually found on the packaging, will indicate that they have passed the necessary industry standard regulations, to comply with and achieve the following certifications.
So, have you got a clear idea about how to choose power bank for your phone and tablet while reading through the passage? Here are some recommendations for you, 20000 mAh is a quite large capacity, however, since the battery drains faster and battery capacity of most electronic devices are bigger, 20000 mAh power banks are cost-effective and future-proof.

I notice that power banks with lower mAh in some cases are more expensive than those with higher mAh. Why is this so? Could it be that the cheaper ones with higher mAh have deficiencies in other areas?
赞赞
Yes, the low cost power banks are made of cheap Li-ion or Li-Po batteries and unsafe protective circuits, even it claims to have high capacity, it’s more likely to be fake.

Hello Vibhuti, the Redmi note 4 requires 5V / 2A input power, so it’s Okay to use your power bank to charge your phone, the only thing you may concern it’s the recharge cycle as the capacity of Redmi Note 4 battery is pretty high, if your power bank is not monster enough I’m not sure it can meet the need.

Hello Vibhuti, you can use your power bank to charge your phone if your power bank is a qualified brand one. Never use the cheap unknown power banks to get away from explosion risks.

Hello I read about the article mentioned above related to power banks … I just want to ask, Which USB Port output(5V 1A or 5V 2.1A) from power bank, would you recommend charging moto e3 power that protects from decrements battery life.
赞赞
Hi Nara, I would recommend output of 5V 2.1A power bank, you see, your device will only draw the current it needs, no worries about it will damage your battery.
赞赞
Thanks, Shirley, it’s helpful. I would also like to ask another thing which I observed in power bank (Intex IT-PB 20K Poly). As I already told you, it has two ports with above output. I connected the motoe3 phone to port (5V 2.1A) output, I felt really surprised as it takes more minutes to cross each and every charging percent than the output port from (5V 1A). Above observation, I felt only after I have charged power bank fully. but it’s not the case when I tested power bank connecting output port (5V 2.1A) to moto e3 power after unboxing it with output power that comes without charging power bank, I felt charging percentage(20%) crosses within 6 mints. Am not sure what has gone wrong. Your guessing/suggestions are much welcome.

Hi Narayanan, in your case it’s quite interesting, theoretically the output of each port should be stable only if your phone doesn’t require the amount of power the port can supply, I mean if the port provides 2.1A but actually the phone only needs 1A, but it’s not the case either because you mentioned the charging with 1A port is faster. I’m wondering whether the output of 2.1A port is really 2.1A… if you want to figure the things out, I suggest you to use a USB meter to measure the power passing through, hope it will help you.

I am not looking to charge my device per se. I want my iPad mini to run continuously for at least 8 hrs at a trade show that does not provide AC power. So I need the power bank to act as an external power supply, which I assume is doable. If so, what mAh should I use?
赞赞
Hi Ron, if you have to use your iPad mini heavily, 8 hours using continuously requires at least a capacity of 10000 mAh power bank to sport that. Considering the portability and power capacity, EasyAcc 10000mAh Ultra-Slim Power Bank is a good candidate.

赞赞
Hi Steve, I would say it depends on the power conversion rate of the power bank, if it’s a branded qualified one, the industry standard rules the rate could not be lower than 60%, our EasyAcc power banks generally could reach 70% to 90%, therefore, in order to meet the daily use requirements for about 1.5 cycles, double of your device battery capacity or higher is a good option

Hi Stephen, since Samsung galaxy T550 features a 6000mAh battery, you’d better get a power bank higher than 10000mAh, if you are a heavy user, 15000-20000 mAh would be more sufficient.
