Nowadays, life has become easier with technology. Almost everything we do every day has been more convenient with the devices and gadgets we use. In addition, most of us do our work and entertain ourselves especially when we are on the go by using our smartphones, tablets, and laptops. If you are planning to purchase a power bank, you don’t simply pick one; you assess the benefits you can get from it. Thus, you must choose the best power bank that suits your needs to make the purchase totally worth it.

However, since these kinds of gadgets are handheld, portable, and are very ideal if you are always on the go, it can only do its function for a limited period of time since its power can quickly drain. Thus, to keep it powered while you are traveling or whenever you do not have access to an electrical outlet, having your own power bank is the best option for you.

A power bank is a handy device that acts as a charger to power your gadgets such as phones, tablets, and laptops. It has a port which connects your gadget to it using a cable.

Due to its great use especially when your gadget’s battery is low, no wonder having a device like this is a must, especially for people who are always on the go. There are a lot of products available in the market right now with varying battery capacities. In addition, their price values differ from each other, too.

What makes the best power bank?

It has a large battery capacity: 

  • A power bank’s battery capacity is the measurement of its ability to charge one or multiple devices either partially or fully. Depending on the power bank’s battery capacity, some power banks can charge a phone or tablet for up to 50%, while other power banks can fully charge 3 or more gadgets.
  • This battery capacity is measured through milliampere-hour (mAh). There are power banks with battery capacities which can be as large as above 20,000mAh. If you have a power bank with a battery capacity like this, you can absolutely fully charge a lot of devices!
  • However, if you choose one with lower battery capacity, the information below will serve as your guide for you to know the capabilities of your power bank:
  • For power banks with 10,000-15,000mAh: You can fully charge a smartphone for up to 5 times, and fully charge a tablet for up to 2 times.
  • For power banks with 15,000-20,000 mAh: You can fully charge a smartphone for up to 7 times, and fully charge a tablet for up to 3 times.

However, you have to be reminded that the larger the battery capacity of a power bank is, the heavier the device is. A power bank with a 20,000mAh battery capacity can weigh as much as 500 grams. Thus, if weight is not a problem for you, it is best to purchase a one with a battery capacity of 20,000mAh above.

 It is fast-charging: 

  • There are power banks having a fast-charging ability. Depending on the gadget you are going to charge using the power bank, a power bank can charge it as fast as the gadget charges through connecting it in an electrical outlet.

 It can charge multiple devices at once:

  • Most power banks available in the market right now have 2 USB ports which can enable you to charge 2 gadgets at once. There are also power banks which have up to 4 USB ports which allow you to charge 4 devices at once. Usually, the more USB output ports a power bank has, the large its battery capacity is.

Thus, it is better to purchase a power bank with more USB output ports, especially if you use a lot of gadgets. However, it would suffice to have around 2-3 USB output ports on a power bank, if you intend to use it for temporary charging purposes only or if you only have around 3 gadgets.

It is of high-quality:

  • Some power banks are made of plastic, while other power banks are made durable and heavy-duty with aluminum-alloy cases. Both can definitely charge your gadgets, but if you want a power bank that is reliable and durable inside and out, it is better to choose a power bank with an aluminum-alloy casing.

It is a great value for money:

  • Let’s face it: Usually, power banks are quite expensive. However, its quality can never be compromised, especially if you know its capacity and what it is made of.
  • Before purchasing a portable charger, assess if its price is worth the benefits you can get from it. In addition, choose a power bank that is perfect for your needs. Usually, power banks with larger battery capacities and more USB output ports are more expensive. Thus, assess well if you need one like this.
  • For example: If you only have 3 gadgets, choose a power bank with 3 USB output ports. In addition, if you have a laptop, smartphone, and a tablet, it is better to choose a power bank with a battery capacity of up to 20,000mAh. However, if you only have a smartphone and a tablet, a power bank with a battery capacity of 10,000-15,000mAh will suffice.

However, you can look for cheaper but well-performing power banks in your tech store, or look for the best one on sale on Amazon if you want a power bank that is absolutely a great value for money.

What to check before buying a power bank?

Assessing the power bank before purchasing it is a wise idea. Thus, this checklist below will guide what to check on a power bank before buying it.

  • Its battery capacity, USB ports, and other features are just right for its price.
  • It is of high-quality and the feel of it is durable itself.
  • Meanwhile, it suits the gadgets you are going to charge using it.
  • It’s truly portable and not hard to store.
  • It can be used even for a long period of time.
  • It has a reasonable warranty.
  • In short, you can assess this by reading some customer reviews about the power bank.
