Powerbanks

Looking to buy a power bank?

Do you often find that your phone battery runs flat quickly? Or are you always checking your battery percentage when you are out and about? Then it might be time to pick up a power bank. Portable chargers come in many shapes and sizes. Some are compact enough to fit neatly into your pocket or bag, making them easy to take anywhere. Depending on the model you choose, you can recharge your phone up to 8 times on a single charge.

Which power bank should I choose?

When you are looking for a power bank, there are a few simple things to keep in mind. The most important feature is capacity. The higher the capacity, the more times you can charge your smartphone, tablet, or other everyday devices. It is also worth checking how fast the power bank can charge your device. This depends on the output power, measured in watts (W). Different phones support different charging speeds. For example, the iPhone 17 supports fast wired charging with a suitable 40W charger, while certain Samsung phones can take up to 45W.

Finally, consider the size and the available ports. If you want to charge multiple gadgets at once, look for a power bank with several USB ports. If you plan to carry it with you on your daily commute or a weekend away, a lightweight model is much easier to manage. If you would like extra advice on picking the right model, read our how to choose the right power bank guide.

What capacity do I need?

Battery size and charging requirements vary from device to device. A compact power bank (up to 10,000 mAh) works well for topping up smartphones or action cameras (like a GoPro). If you want to charge an iPad, tablet, or laptop, you will need a higher capacity (20,000 mAh or more). A 20,000 mAh power bank can charge a smartphone roughly twice as many times as a 10,000 mAh power bank. Keep in mind that a 20,000 mAh power bank is heavier to carry with you.

How much power (wattage) do I need?

Charging speeds vary depending on the phone model you use. Because of this, it can be difficult to know how many watts you need to charge your phone at a fast speed. To make things simple, we have put together a list of common phones alongside their maximum charging wattage.

Why do I need a power bank?

Most of us have experienced being out on a long day only for our phone to run out of charge right before getting home. That can be awkward when you rely on your phone for train tickets, payments, and staying in touch. Having a charged battery gives you peace of mind. A phone often struggles to last through a full day of steady use, which is why a portable charger is so practical. A typical power bank can top up your phone 1 to 4 times, keeping you going all day or throughout an entire weekend.

A power bank for travelling and days out

When you are travelling, a portable charger is very useful to have in your bag. So many everyday things now run through your smartphone, including boarding passes, maps, travel updates, and hotel bookings. Running out of battery while away from home can cause unnecessary stress. If you do not want to carry a bulky charger, there are lightweight options that still provide 1 to 1.5 full charges for your phone. They are simple to take on any journey.
