  • Li-Polymers batteries

Commonly known as LiPo batteries, these batteries are generally robust and versatile, especially when it involves the dimensions and shape of their build. They’re also lightweight, have a particularly low profile, and have a lower chance of getting affected by leaking. On the other hand, when compared to Li-ion batteries, Li-Po batteries are more costly to the manufacturer and they have lower energy densities (a lesser amount of power can be stored).

This type of battery does not lose its actual charging capacity after overtime charging. There is no need to worry about explosions. It’s totally safe from explosions. But Li-po batteries are more expensive and take more time to charge compared to Li-ion batteries. Moreover, the power transfer rate is also low compared to Li-ion batteries.

What power bank should you buy? Read on to find out our recommendation!

  • Li-ion battery

These batteries are well known for their high energy densities (more power can be stored), they are cheaper when compared to Lithium Polymer batteries. Lithium-ion batteries lack the memory effect (when batteries become harder to change over time) and suffer aging when not in use. Li-ion batteries also have a history of explosions.

The good thing with lithium-ion batteries is that they don’t self-discharge quickly. This means that you can put a charged battery away for a long and even after months, it would have a large percentage of its charge left for your use.

Even though it isn’t all good with these lithium-ion batteries. They tend to age and it continues to happen even if the battery is not being used. So it decreases its capacity to retain charge over a periodof your timeeven when left unused.

Fact Li-ion Battery Li po Battery
Weight More than Li po battery Lightweight
Energy Density High Low
Chance of Explosion When its overcharged Not at all
Price Cheaper Expensive
Aging Lose actual capacity on overtime charging Does not lose actual capacity
Charging Duration Long Short

Which Power Bank Battery is Good?

An economical option is a Li-ion battery, the only nondesirable con is the charging duration. If you can afford to spend a few more bucks, I would definitely suggest the Li-po battery, since the pros are more desirable. This is the best power bank battery in 2021.

4) Number Of Ports In power banks

Ask yourself: has there ever been a situation where you have to charge multiple devices at once? If your answer is positive, then you must buy a power bank with multiple ports. So you can charge your smartphone and Bluetooth headphones at a single time. I have seen that most business people have two phones. One for personal use and another for business purposes. They should also buy a power bank with multiple ports.power-bank-ports-1-300x169

There is one single port available in every small power bank but In medium and large power banks there are multiple ports available. If you want fast charging from both ports, then the output voltage and current from each port must be 5v and 2A or 9v and 1.67A. Otherwise, you can also buy a power bank whose output from one port is 2A and the output from another port is 1A.

With this power bank, you can charge your smartphone from a 2A port and other devices like headphones, gaming devices, and speakers from a 1A port.

Furthermore, check the charging port. You should buy a power bank with the same charging port as your mobile phone charging port. So, you don’t have to carry extra cable in your bag wherever you go.

5) Size And Weight

If you need to carry a power bank in your pocket then you should buy a small and medium-size power bank. Also, a small and medium power bank is not heavier so it’s easily portable in the pocket. For charging your laptop from the power bank, you have to buy a very large and heavy power bank but don’t worry you can carry it with your laptop in a laptop bag.

It all concludes that for regular use, you should buy a small and medium power bank. Only when traveling, you should buy a large power bank, and for your laptop, you should buy a huge power bank.

Since the size also depends on the power capacity, the most powerful power bank will have the largest size, in most cases as discussed above.
