Best power banks: A complete buying guide

All you need to know before buying a great power bank

Picture of a power bank

Finding the best power bank to charge your devices is often difficult. There are many amazing products out there but there are also many cheap power banks that will only be a hassle to use, so it’s important to know what to look for to ensure that you choose something good. Check out the buying guide below for all the info you need to know to find a great power bank for your needs:

What are power banks?

A power bank, also knows as portable battery charger, is a device that is used to recharge various electronic devices, such as smartphones, tablets, and wireless Bluetooth headphones, connecting via USB cable to provide a charge. While designs vary, a power bank is usually a compact and lightweight device that is easy to carry on the go.

Why should you buy a good power bank?

A good power bank is a very convenient device to own. Most of us have smartphones so know just how often they need to be recharged, yet we don’t always have access to a power source to charge the device. A power bank offers the perfect solution, letting you recharge most portable devices when out and about, saving the hassle of dealing with a dead battery!

How to choose the right power bank?

It is important to think about a few things before you buy the best power bank, as you need to ensure it is suitable for your needs. Not all power banks can charge every device, so here are some things to consider so that you get something suitable:

  • Charge Capacity: Always make sure that a power bank’s charge capacity is big enough for your devices. Measured in milliamps per hour (mAh), you need to ensure this number is high enough to provide a full charge for your device, otherwise it won’t charge it. Think about what devices you are charging and check whether the mAh rating is high enough. For instance, 1000mAh power banks are suitable for older phones but you’ll need between 2000-5000mAh for newer smartphone, while tablets will need a much higher rating closer to 10,000mAh
  • Output Current: The output charge current of a power bank determines how fast it charges a device, so always keep an eye for the maximum output current. For instance, a 3amp rating usually means the power bank is a fast charger, and this higher output is needed for larger devices like a tablet. Lower outputs aren’t necessarily a bad thing - if you only need to charge a smartphone then around 1 amp should charge quickly enough.
  • Ports: The first power banks only had one port to charge a single device, yet there are now many products with multiple outputs for charging serval devices at once. These can be very convenient but make sure that they provide enough output for each device, as the output current may be shared across all the devices instead of providing each one with the maximum current, meaning longer chare times.
What is the best kind of power bank in the UK?

Here are some of the main types of power banks you can buy:

  • Mini Powerbank: Smaller power banks designed for a single device, they are very cheap and portable but may not have the highest capacity or charge outputs.
  • High Capacity Powerbank: Typically comes with 10,000mAh and above, with the larger capacity being suitable for large devices like tablets. If used on a smaller device the charge lasts much longer.
  • Solar Powered Powerbank: Features a solar panel to help charge the power bank, meaning you can recharge the charger if it dies while being on the go.
