5 Tips To Buy The Right Power Bank For Mobile

Portable power banks have become a real lifesaver for the modern day user, you will no longer need to worry about having a low battery level on your mobile device when you’re out an about. When choosing power banks, or also called backup batteries or battery chargers, it may be a bit confusing to decide which one is best suited to your needs , as it comes in all shapes and size. In fact, there are some power banks that can only handle your smartphone, so if you want to charge a bigger device like a tablet or a digital camera, you may need a more powerful one.

So how do you know which power banks are better than the others when the price is not the main factor? Let us help you! The following article will walk you through the 5 key features that you need to remember in order to buy the right power bank. 

1. Capacity

The capacity of the power bank, measured in milliamp-hour or “mAh”, is the key indicator of how much power your portable power bank can charge your devices and how often you need to recharge it.

The common size of the capacity normally ranges from 2,000mAh to 15,000mAh, or even up to 40,000mAh for some powerful mobile chargers. A higher number means more power to charge your devices and use it multiple times (normally 3 or 4 times) before having to recharge it. For example, if you just seek for a power bank for your smartphone in case of emergency, a 2,000mAh power bank will suffice for a boost in the battery to get you out of trouble. However, the bigger capacity mobile charger like a 10,000mAh one can charge your smartphone up to 4 times without recharging the power bank itself.

Depending on what devices you use the power bank for, you may need bigger capacity – more mAh – to be able to charge them fully. Specifically, bigger devices like iPad or digital cameras will draw more power than smartphones; so, you definitely need a bigger power bank with bigger capacity. For instance, the 2,000mAh mobile charger is not capable of fully charging a tablet, you may need at least 6,000mAh to do it.

2. Output

Power output, measured in Ampere or “A”, refers to how fast the power bank can charge your devices. The higher the ampere, the faster the devices can be charged with the compatible USB cable.

You can easily find either 1A or 2.1A output port, or both, on the power bank. The 1A output normally can handle most smartphones pretty good, but it will be at a slower rate if charging a tablet. In that case, you will need a 2A output port for optimal charging.

3. Number of USB Port

The number of USB ports determines how many devices the power bank can charge at a time. The more USB ports the power bank has, the more devices you can charge.

If you just want a power bank that fits in your pocket or your purse, those with one USB port like TP-Link Ally Series 15600mAh High Capacity Power Bank is all you need. This specific power bank can charge two devices with 2 USB output ports and 15,600mAh battery capacity, which means you can charge it multiple times as well.

If you want to charge more than one device, you should look for two ports: one for 1A output, one for 2.1A output. You can use these two ports to charge:

  • Two smartphones at the same time
  • Or using the 1A output for a smartphone and the other 2.1A output for the bigger device like iPad
  • Or using both two ports for two big devices like an iPad and a Bluetooth camera

Depending on which two devices you are charging at a time, the total output that the power bank splits to charge the devices will be differently, which means it may take a longer time to get both devices charged fully. For example, assuming that a 2-port power bank with the total output of 3A takes around 4-5 hours to charge two smartphones. However, same with that power bank, it will take up to 6-8 hours to charge a smartphone and a tablet simultaneously.

4. Input

Power input, also measured in Ampere, refers to how fast the power bank can be recharged from the power source. The power input ranges from 1A to 2.4A input. And again, the bigger the input number, the faster it will recharge. 

5. Safety

Safety is another factor that you need to consider when choosing the right power bank.

In Australia, any supplier of battery power banks may have to follow ACMA electromagnetic compatibility (EMC) regulatory arrangement.  

The qualified power bank is the ones that have passed the industry standard regulations and certifications to achieve at least one of the following logos on their packaging.
