How Many mAH Do I Need? – Power Banks and Portable Chargers

Did you know that almost 90% of mobile users panic about losing power on their phones? Research conducted by electronics giant LG found that nearly 9 out of 10 people suffer from ‘Low Battery Anxiety.’

For many people today, having constant access to a smartphone has become a life-essential, meaning that a depleted battery can ruin a day. From working to gaming, the need for a longer battery life grows greater for consumers, and has led to the rise of the mobile power bank. With so many options available, finding the right power bank for your customers, clients or employees isn’t always the easiest task.

Unless your power bank is for personal use, the odds of knowing your end consumers phone specifications are slim. However, with the capabilities of the modern smartphone, sourcing a power bank with a higher mAh (Milliamp Hour) capacity is your safest option for satisfaction. For example, a top of the range iPhone 7 has a 1960mAh battery, meaning that it can be fully charged with a 2000mAh power bank. However, one of these power banks would only give a Samsung Galaxy S7 Edge (3600mAh) slightly more than 50% battery charge. Whereas a 4000mAh model would allow you to fully charge the iPhone twice, or the Samsung once.

It is also worth noting that older phone models draw their power differently to newer handsets. Older phones only draw 1Ampere (1A) to charge their batteries, whereas newer phones and tablets require a 2.1A input to charge at full speed. For newer phones, a lower electrical input leads to slow charging. For older models, a higher electrical input can damage the phones battery. If you’re looking to source a power bank that can safely charge both styles of gadget, there are a couple of options available:

  • Dual-Ported Power Banks: Power Banks that feature two USB ports are designed to offer both 1A and 2.1A inputs, ensuring that your end user is drawing the correct level of power for their gadget.
  • Protection Power Banks: For improved safety, Sycal recommends power bank models that provide Over Voltage Protection (OVP), Over Charge Protection (OCP) and Over Temperature Protection (OTP), to ensure that all aged gadgets can be charged without the fear of battery damage.
