Investing in a good power bank is something that will go a long way, and this alone makes the investment totally worth it!

You’ll find endless options when you go to buy one. You might get overwhelmed with the number of choices at hand and may even get lost. However, if someone can recommend you the best power banks, reaching a decision will become a tad easier, and that’s exactly what we’re here for!

We’ve compiled a list of the best small power banks for you to choose from. So, before you invest in any portable power bank, we suggest you go through our list first.

What to Look for in a Small Power Bank?

Choosing the right portable power bank is easier if you know what features to look for. Some power banks have more features than the others to suit different users, and with that, their price differs too. Your decision should be based on the features that you think are essential for your use. Some of the most important features that you must look for in a small power bank are as follows:


The first feature that you should look for in the device is its size. Since a portable power bank is supposed to be easy-to-carry, its size must be travel-friendly. It should be small enough in size that it fits in your pocket or your purse. It shouldn’t weigh too much. Some power banks that have a large power capacity are larger and heavier, hence not as portable. Look for a power bank that is a fun size and offers a great charge capacity.


One of the most important factors that you must consider before buying a portable power bank is its power or the size of its battery. The more the power, the more times it can charge your mobile phone.  Power banks could have a battery capacity of anywhere between 5000 mAh to 20,000 mAh (and more!). The bigger the number, the more you’re able to recharge your phone. If you’re on the go for most of your day, you’ll need to invest in a power bank that has a greater capacity.

Power Indicator

You may not realize how important this feature is until you end up traveling with a dead power bank. It would be best if you bought one that has a power indicator, indicating the level of charge of the bank. It’ll help you keep track of when you need to recharge your power bank. Without a power indicator, you’ll have no way to tell for how long it can keep charging your mobile phone. You may even end up in a sticky situation.

Charge Time

You certainly wouldn’t want to get stuck with a power bank that takes forever to get fully charged. You should look for a portable charger that gets charged quickly. A power bank with a Quick Charge (QC) port is a good option to invest in. A 20,000 mAh power bank equipped with a QC port means that it’ll get fully charged in just 6 hours.

Variety of Ports

Your best bet is to buy a portable charger that has a variety of charging ports, including ports having an amperage of 2.4, 5.0, and a QC port. This variety will enable you to charge multiple devices at the same time.


As much as assuming that only the power banks from renowned brands are reliable, a brand does count. Instead of buying a cheap power bank, you should consider investing in a portable charger from a well-known brand (such as Anker or Belkin). It may be more expensive, but it’ll go a long way. It’s more like incurring a one-time cost and then reaping the benefits for months, even years!
