Technology is simply something none of us can imagine our lives without. That said, all the gadgets and devices we use every day are really important, and we really don’t want them to die on us when we need them the most. 

However, and let’s be completely honest here, manufacturers of various devices didn’t quite put an emphasis on battery life when they were designing them, did they? This is especially true when it comes to smartphones but other devices like laptops and tablets aren’t any better. 

So, why make portable devices if we must be chained to the wall with a charging cable most of the time? Fortunately, some noble soul came up with a great idea to create power banks. 

Therefore, when your phone or tablet or whatever is about to run out of battery, you simply connect it to the power bank, and you’re good to go. With that in mind, here’s how to choose a power bank for your devices. 

The weight and size

The first thing you want to consider is the weight and size of your power bank. They’re basically portable charges, so it’s only logical that they should be easy to carry around. 

Therefore, something seamless enough to fit into the palm of your hand, and that isn’t too heavy should be your prime criteria. 

Luckily enough, power bank manufacturers consider this option, and they do their best to make these banks as practical and compact as possible. That way, if you’re charging your smartphone while going for a walk, both can probably fit into your pocket.

The capacity

Power banks don’t have endless power, which means you have to charge them too. However, depending on their capacity, they can charge your devices at least two or three times before you have to plug them into the wall as well. A power bank with 10,000mAh should do the trick. 

However, if you want to be sure that you’ll have enough juice for your devices on the go, you might consider opting for a 20,000mAh power bank, just to be sure. This is especially true if you need to charge something larger than a smartphone, such as a laptop, for instance. Furthermore, power banks with more capacity tend to be larger, so try not to overdo it. 

Charging speed

Now we are getting to the fun part, which is charging speed. The charging speed of a power bank determines both the amount of time it’s required to charge the bank, as well as the time required for a bank to charge your devices. 

Most power banks have at least one 3.0 Quick Charge port. That said, you’ll still need to wait for a couple of hours to fully charge your device. Of course, how long it will take depends on the device itself. 

For example, a laptop may take several hours to fully charge, whereas a smartphone may only take one or two hours, tops. The results may vary depending on the bank’s capacity, ports, the device it charges, and so on.

Ports available

As mentioned before, the majority of power banks have at least one 3.0 Quick Charge port, but that’s not all you should look out for. For most people, one port is more than enough, as they’ll most likely charge only one device at a time.

However, you should consider some convenience too and opt for a power bank with at least two ports. Make sure that the power bank supports dual charging – otherwise, two ports won’t mean much. Who knows, you may need to charge two devices at the same time or share your power bank with a traveling companion. Simply put, it’s better to be safe than sorry. 


Choosing a power bank may seem simple enough, but it’s always better to pay some attention to details. No one wants to waste money on useless devices, after all. Therefore, when you go out looking for an ideal power bank for your devices, make sure you take the time to really consider your options.
