Power Bank and Portable Charger Buyer’s Guide

A smartphones battery life is known for running low faster than we’d like but fortunately, power banks are a convenient, portable solution to this problem. Use this buyer’s guide to find the best portable chargers available.

Power Options

  • Small – Small power banks will be between 2500 – 3000mAh. They usually have one USB port and provide enough power to fully charge a smartphone. These smaller options are cheaper and more compact in size so they are ideal for portability and providing extra battery capacity in emergency situations.
  • Medium – Medium-sized banks will be between 3500-10000mAh. They usually provide enough power to charge a smartphone twice or charge a big battery phone once. They are a great option if you are looking for a solution to use regularly or if you’re heading on a weekend trip and you want to keep your phone charged. These are more expensive than smaller options.
  • Large – Large options will be 10,000mAh – 40,000mAh. They can provide enough power to give multiple charges for multiple devices. They are heavier and more expensive but they provide a lot of power that should get you through several days without using wall sockets. These larger options are less portable but are ideal for charging lots of devices.

If you find that a regular power bank doesn’t meet your needs for energy, you might want to consider a portable power station. These are larger units that can handle a lot more charge, making them ideal for longer trips or powering more demanding devices.

They’re not as easy to carry around as the smaller power banks due to their size and weight, but if you need to keep larger devices like laptops or cameras charged, or if you need power in remote locations, they’re a good option to look into. Just remember, the increased power comes with increased size, so they’re better suited for situations where portability isn’t your top priority.


If you want to charge more than one device at a time look for a charging option that has two or more output ports.

The number of charging ports and the type of charging ports is important to note. If your phone or device charges using a USB-C cable then look for a power bank that has a direct USB-C port for more efficient charging.


Some USB power banks come with a cable included, and some actually have built-in cables. Built-in cables are great in theory because it means you won’t forget the cable but actually it’s better to have ones you can remove.

Cables you can remove gives you the freedom to change them and switch between cable type as needed. It is also better as you can’t easily change the built-in cable if it becomes damaged or stops working.

Size & Shape

The charging capabilities and the max output often comes hand in hand with the size of the charging brick. The more power the power bank offers the bigger and bulkier it is going to be.

Depending on your needs, it might be best to find a middle ground between portability and power delivery.

Battery packs usually come as either a rectangular brick shape or a cylindrical pen shape. The pen shape is more portable and easy to carry around but also usually offers less charge and is less stable.

Block chargers are far more common and tend to offer the highest capacity.

LED lights

Some banks have charging-status lights that show how much battery power is left. This is a very useful feature and will help you know when you need to recharge the bank.

Smartphone Capacity

If you are looking for a power bank for your smartphone, take a look online to find out the battery of your smartphone.

Once you know the capacity and charging requirements of your phone you can calculate how effective the power bank you are looking at will be. You should also make sure your phone model accepts the amps of the bank.

Most power banks offer 1 amp/ 5 watts or 2.4 amp/ 12 watts but there are some phones that only accept 2.1 amps or higher so be aware of this.


Safety Features

An important factor is safety features including over-current protection, over-voltage protection and overcharge protection.

The battery pack should have undergone testing to ensure it’s safe to use. The product needs to be durable, high-quality and safe to use.

Additional Options

Solar power – if you are looking for a more eco-friendly option or you will be away from a wall outlet for a while, a solar-powered bank could offer a suitable solution.
