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.

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 2.4Amps (short for ampere and it’s a unit of current). 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.

————————————————————————————-

Phones get faster every year, but battery life doesn’t seem to get any better. If you need to keep your smartphone – or tablet or other USB-powered device – going all day, you need a power bank.

So how to choose a suitable power bank? Before making a decision, you could reder to this passage: Don’t buy power bank before you read this.

— So, what’s next?

— Surely, to buy one for myself!

— So where to buy it? Or where to buy a reliable power bank?

Undoubtedly, having a reliable power bank for your smartphone, or tablet or other USB-powered device to boost a depleted battery can be a real lifesaver – especially when a charger isn’t accessible.

Amazon

Online shopping for a power bank, that’s just a peice of cake. However, on the other hand, you should have to select one, a branded or a generic? Although Amazon has offered you a long list of selections, actually, you should exclude those unwanted one by one. And to the point, that still could not assure the qualities.

Similar to Amazon, eBay has rounded up all kinds of power banks for you, even you wanna buy some branded classic which is however not available in stores, via a third-party or private person. But it has the same shortcoming with Amazon, that is, assured-quality.

Branded Store

If you decide to buy some branded power bank, its official online shop or local shop is a good choice. At least, you’ve avoided 50% chance to get hurted while charging your devices. Of course, it’s not absolute. Anything to do with battery will have the chance for accidents, for example, to explode.
