Some Factors

1. Decide Budget For Power Banks

Before we buy any product we should decide our budget to invest for that product. According to me, instead of doing long time and more investment like a refrigerator and Ac, you should invest less money for 2 to 3 years because most small electronic devices work properly for 2 to 3 years after buying them. So, invest less money according to your requirement and change the product after using 3 to 4 years. Therefore you can use the latest and new product.

Below in the table, I give a price range according to capacity of power banks.

Then open your device’s setting menu, go inside the battery area and check the battery capacity of your device. Also, ask another question to yourself: where and when you want to use your new device? means In traveling time, At your office, At home or In night duty job.

Small Power Banks ( Below 6000 mAh )

Nowadays we all are using smartphones and the battery capacity of each smartphone is between 3000 mAh to 6000 mAh. If you want to use a power bank only on weekends to keep fully charged your phone when you are at home then this capacity power bank is best for you. This product is not perfect for people who want to use it on a daily basis. Normally, We can use 70% to 80% power of the power bank due to transmission loss means usable charge on a 6000 mAh power bank would be only 4500 mAh to 4800 mAh.

Medium Power Banks (6000 mAh to 14000 mAh)

Medium size power bank is best for people who have to charge their phone twice after leaving the home in the morning and before returning home in the evening and they remain far from the electric plug. In short, a better option for those who want to use it on a daily basis. With a 14,000 mAh power bank you can charge your 4000 mAh smartphone battery 2.5 to 3 times. Also, you can use this on any long trip also.

3. Li-ion Vs Li-polymer Battery

In general, No more difference between both batteries in power supply but there are some specifications for both batteries which i will explain here.

Li-Po Power Bank
Li-ion Power Bank
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 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 power transfer rate is also low compared to LI-ion batteries.

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 ageing 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 period of your time even when left unused.

4. Number Of Ports In power banks

Again ask yourself, there is ever 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 headphone 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.

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 2A port and other devices like headphones, gaming devices, and speakers from 1A port.

Furthermore check the charging port also. 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 more heavy 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 very large power bank.

6. LED Indicator

Some power banks feature LED lights that let you see how much charge is left in the bank. usually four or five lights that all glow when the bank is full and go out as power is drained. This is particularly useful if you’ve got a larger bank and need to know how much charge is left inside. The Problem of overcharging is also removed from the LED indicator.

7. Solar Panel In Power Banks

These days, This product is new to the market. Each solar energy bank is supplemented by the embedded solar array . This provides solar support and emergency power copy because it recharges the facility bank on exposure to the sun.We can charge any electronic device up to 5 volt from these solar power banks. It saves electricity.

8. Wireless Power Bank

Nowadays you find wireless charging hardly in the Indian market because it is totally new technology. Wireless chargers transfer energy through the inductor coil. This product is very expensive. Power loss occurs the most during energy transfer from this product to charging product. If you want more buying guides on wireless power banks then you can check another article on it.
