How to choose the right power bank for you?

There’s no worse feeling than running out of power on your devices when you’re out and about. Avoid the dreaded dead battery by carrying a power bank with you. If you have decided on buying one, you can follow our tips on how to choose the best power bank for you so that you can stay powered up on the go - anytime, anywhere!

Features to consider when looking for a new power bank

There are many different options when it comes to buying a power bank, so it’s important to understand the different characteristics of each one so that you can be sure to have the perfect power bank for you.

Evaluate the capacity you need for your power bank

The easiest feature to consider is the capacity of the power bank. In short, the higher the mAh number for the power bank, the more power it delivers. The mAh value is an indicator of the type of power bank and its function:

• Up to 7,500 mAh - Small, pocket-friendly power bank that is usually enough to fully charge a smartphone from once until 3 times.
• 7,500- 14,999 mAh - Medium power bank likely to fit in your jacket pocket that is usually enough to fully charge a smartphone 4-5 times.
• More than 15,000 mAh - Large power bank that is usually enough to fully charge a smartphone 5 or more times. Due to their size, these are carried in a bag.

Often, the higher the mAh means the bulkier the power bank, so if you’re looking for a more slimline model you may have to sacrifice some power. Additionally, if you’re planning on using your power bank for traveling, although most power banks can be carried on as hand luggage, it’s worth remembering that any power bank over 27,000mAh cannot be taken on planes at all and can be confiscated at the airport.

Which power banks are allowed on the plane?

If you are going on holiday and you would like to carry with you a power bank, this must not exceed the maximum rating of 100 watt hours (Wh). This can be easily calculated by dividing Milliamp Hours (mAh) by 1000 and multiplying the result by voltage (V). Larger power banks may be carried in consultation with the airline.

Consider the charging speed of the power bank

A power bank charging speed is usually measured in voltage and amperage. Amperage is the amount of electricity transferred from the power bank to the electronic device, while voltage is the amount of potential energy. If we multiply volts by amps, we will get wattage, which is the total power. For instance, with its 22.5W charging speed, our M2 PowerBank can charge your phone to over 55% in just 30 minutes*. Never compromise functionality with appearances, match your power bank to your style."
