Back in 2016, Electronics giant, LG, conducted a study into how consumers use their phones. It was found that almost 90% of participants started to develop ‘Low Battery Anxiety’ when their devices start needed a little juice.

There is no wonder that power banks have become one of the most effective promotional product options over the last couple of years.

With so many models and varieties available, finding the most effective portable charger for your end-consumer can be a bit tricky, so we’re here to help.

How many mAh do I need?

If you’re looking for a branded power bank, there’s a good chance you’ve seen the abbreviation “mAh” creeping up a lot. mAh (milliamp hour), is the measurement used to represent the cappacity of a battery. Simply put, the more mAh a power bank has, the longer the battery will last before it depletes.

To determine how many mAh your power bank needs, it’s important to know what current mobile devices are popular and what their battery capacity is.

Most of the latest phones on the market will start around 2600mAh, but not exceed 4200mAh depending on capabilities:

  • iPhone 11 – 3046mAh
  • Galaxy S10 Plus – 4100mAh
  • Mate 20 Pro – 4200mAh

This means if you get a 5000mAh power bank, you can fully charge one of the above phones from flat to 100% with a little bit extra before needing to recharge the bank.

If you’re looking for your power banks to charge, it is worth remembering that these may vary between 5500mAh and 8800mAh.

What output do I need??

Should fast charging be a priority, you may wish to consider the Amphere (A) output of the power bank in question. Most older phones draw 1A to charge their batteries, where as new phones and tablets require a higher amphere to charge at an optimal speed.

To support older and newer phones, many power banks offer dual USB ports with seperate outputs to ensure safe charging. However, newer bank models may offer multi-output functionality to charge all models optimally with a single USB port.

Do I need a wireless charger?

Induction charging; or wireless charging, has been featured in a number of mobile phone models over the last three years, but not all models offer this functionality. Although wireless charging can be more convenient, almost all devices charge slower on these models when compared to cable charging. In fact, devices on average take 15% longer to charge when the supplied power is the same amount.
