Best Power Banks to keep your Smartphone’s Juice up

Share this Article

Even though the smartphone manufacturers are trying their best to elongate the battery life. After 10 to 12 hours of continuous usage, the battery has to die and that is when you need a backup. While finding a charger and a switch is the most reliable option, you don’t always get hold of it. Especially in a situation when you are driving or in the middle of something important. In such a case, power banks are the only solution.

While these tiny devices are known by many names like battery packs, portable chargers, fuel banks, and pocket power cells, they all do the same job, power up your phones and tablets. You simply have to charge them and stuff into your carry bag. And, whenever your phone’s juice declines, you can connect it with your phone.

Even though it’s not an expensive purchase, most of the people end up buying 2-3 power banks, mostly because they don’t know how to buy one. To make sure, you don’t have to buy 2-3 battery backups, before you get one that’s made for your phone, here is a brief guide for you:

Buying Guide for Power Banks


One of the most important factors to consider while buying a power bank is checking the capacity. The first question will be, it’s a smartphone or tablet that you need to charge. Some gadgets take more charging than others, so depending on your device model, you will have to select a high capacity or low capacity power bank. To be specific, check the smartphone’s specifications and find out the battery capacity.

Older phones have a battery of 1000mAh, whereas the newer phones have the capacity of up to 3000 mAh. For e.g., Samsung Galaxy S6 has a battery capacity of 2550 mAh, and it’s always good to have a power bank with a little extra juice. So, our recommendation will be opting for a high capacity power bank, like 3000 mAH or more. For tablets though, you will need a better and more powerful power bank.

Extra tip: Power banks provide only 65% battery of what they claim. For instance, if it says 10,000 mAh, it offers just 6500 mAh. So, look for a higher capacity power bank.

Type of Battery

Power bank’s batteries come in two different types Lithium-polymer (Li-Po) and Lithium-ion (Li-Ion). In comparison to Li-ion, the Li-po power banks are lightweight and have slim built. Li-Po is also a newer technology and there is a very lower chance of going through leaking electrolytes. So, it’s a better choice.

Number of USB Ports

Earlier, there used to be just one port with power banks, but with the increasing demand of customers, manufacturers are rolling out more than one port. Power banks with higher mAh can have more than one USB ports, this can be useful for customers who keep more than one phone.

 But, when you buy a power bank with more than one port, do check its output current capabilities. Also, remember that USB ports with multiple ports might offer slow charging to multiple devices.

Output charge current

When buying a power bank, check the rate of output charge current. While smartphones can take up to an amp, tablets will need around 2.5 amps, and other gadgets with faster charging will need 3 amps.

Look for a higher output charge current as the lower is the current, the more delay you will face in one round of charging. Just check the output current capabilities written on the power bank.

Extra tip: Even though the phone has a small current requirement, a high output power bank will adjust accordingly, the phone will squeeze only what’s needed.

Other features

Some power banks may have both Type C and MicroUSB input for charging it. It’s a benefit if you don’t have a MicroUSB cable with you. Make sure the quality of the cable is good so that the device is saved from overheating and power surges. Additionally, you should look for a lightweight and sleek design, so that it’s easy to carry.
