Smart gadgets like smartphones, tablets, iPads have become essential utilities. They make our lives easier, but only as long as the battery is not exhausted.

Many people can get what you call “low battery anxiety” when the phone battery starts running low. Besides causing a great inconvenience, it also disrupts communication.

So why should your phone be out of charge ever?

The invention of mobile battery packs or juice packs, external power or the backup battery has made our lives easier. It lets you charge up your smartphone when it dies on you in the middle of the woods.

Understanding mobile battery packs

Mobile battery packs are lightweight and extremely portable. They are as mobile as you are. You can carry it with you in your backpack while traveling or fit it in your purse while going to work.

Either way, mobile battery packs are an extremely convenient option when you are stuck out of your comfort zone, away from the conventional wall-mounted sockets.

Battery packs come in different shapes, sizes, colors and specifications—you can make a purchase depending on your personal requirements. You can get one with just single output port or buy a multiple output port battery pack, which will let you simultaneously charge more than one device.

It’s very easy to use as well.  All you need to do is plug in your battery pack and charge it 100% before you can let your dead phones leech off the electrons from these guys.

Which battery pack is best for me?

Picking the perfect mobile battery pack for your gadgets can be a confusing task considering the pool of options available on the market. But it can be made easier than you think.

The battery packs can be evaluated based on power, portability, and the price you pay for it.

Most mobile battery packs can offer you power ranging from 2000mAh to 10,000 mAh.

For those of you who don’t understand what mAh means milliamp-hours. The concept is simple. The bigger, the better.

How much power does my smartphone need to fill it’s battery?

A smartphone takes up anything from 2000mA to 3000mA to fill its battery. So if you have a backup of say 10,000mAh, you will be able to charge your phone/gadget anywhere from 4 to 5 times, provided your external battery pack is fully loaded.

The 2000mAh power bank will be your friend in need, for sure. When your phone is dying, and you need a little bit of boost, this is a good option. But it can’t charge your phone multiple times.

That being said, you cannot charge your tablets either using a 2000mAh power bank. Well, at least it’s advisable not to do that.

If you own a smartphone and a tablet/iPad, then a 6000mAh powerhouse can be a financially feasible option. It lets you charge your smartphone 3 times once it has drained its battery, and you can fill up your tablet almost 1.5 times before it needs a recharge.

If you often travel and spend a lot of time out then, you can opt for the mega 10,000mAh power fortress. It will charge your phone 4 times and your tablet 2.5 times. And if you don’t own a tablet, 10,000mAh is still a good option as it lets you charge your smartphone at least 7 to 8 times, which is great when you are traveling, especially to off-beat places.

Can I charge other gadget using this juice bar?

The interesting fact about the battery packs is that it can charge absolutely anything as long as it has a USB to charge the device.

Charge your GoPro, JBL, iPhone, iPad, Kindle—as long as your device draws 1AMP current to charge itself.

The amount of current your device can withdraw, determines the charging speed for your gadget. If it can extract more electrons, it will certainly charge better.

Usually, a 1AMP output device will charge your tech toys very slowly, be it your smartphone or your tablets.

An output of 2AMP ensures fast charging for your smartphone—almost twice the speed. It also fills up your tablet faster since most tablets withdraw 1.5AMP current to charge themselves. iPads can use as much as 2.1AMP to fill themselves.

How effective is charging more than one gadget at a time?

Now all these data and calculations are valid when you are charging one device at a time.

If you want to charge two devices at a time you need to get a power bank which can give a total output of at least 2.1 to 2.4AMP. It gives optimal charging for both the gadgets.

For a faster simultaneous charging of all devices, go for a chunk power box that gives a total output of 5.4AMP.

The option between a multiple port power bank or a singular port power bank lets you pick a suitable solution for yourself. Usually, the battery packs with more than one USB ports come with larger potential energy stored within itself. You and your buddy can simultaneously charge your respective smartphones/ tablets, or any gimmick.

Share the energy, spread the love with a numerous USB port powerhouse.

All mobile battery packs come with at least one cable. It is usually the standard USB cable which you use to charge your gadgets.

What cable do I need to use to charge my gadget?

Charging it is very easy. All you need to do is plug the USB sides of the cable into the groove provided in your power bank, and fix the other end of the cable to your smartphone.

Even if your smartphone or tablet uses a lighting connector or a USB-C connector, you can use it to charge your device, although you might need another cable to connect it with your power bank.


You can reap the maximum perks of an external mobile battery pack only when it is fully charged. So make sure to always keep your powerhouse full.

Mobile battery packs are safe to use. Most of them also come with a warranty. If you invest in a good battery pack, you will be able to make the most of it for a long time. It is advisable to not purchase battery packs off the roadside as there is no guarantee about their quality.
