9 tips for buying a power bank for your device

Power bank is the most used gadget nowadays and we use this power bank to charge our devices anywhere without access to the power grid. We all know that power bank comes with different sizes, capacities, features and price. But when it comes to buying the best power bank for our smartphone and device, it becomes an arduous task. That’s why in this article we are going to cover “9 tips for buying a power bank for your device” that you should know before buying the Power Bank.

1. Match the charging capacity to your device.

First of all, think about the device you are trying to charge, are you going to buy a power bank for your smartphone or tablet? This is because tablets require more charging and capacity than smartphones. You need to purchase a power bank that meets the specifications of your device.

There are many power banks on the market with different capacities and sizes such as 5,000 mAh, 10,000 mAh and 20,000 mAh. Think of a power bank as requiring a battery that is at least the same size as the device. Make sure your device is fully charged at least once.

The output of the power bank plays an important role in the device.

A typical power bank provides the device with 1 amp of power output. If you have a smartphone or device that supports input charging above 1 amp, purchase a power bank with an output rate above 1 amp.

For example, if your device supports 5V / 2.1 amps charging, buy a power bank that offers 5 / 2.1 amps output.

2. Power bank capacity

As above said, the Power Banks are available in a variety of capacities such as 5,000 mAh, 10,000 mAh, and 20,000, and every device has different battery capacities. If you use the power bank to charge your tablet, you need a large battery while smartphones require less battery than tablets.

If you are using a 3,500 mAh device, then you have to choose Power Bank with a capacity of 10,000 mAh or more. So, as a result, the device will receive doubled power juice. Do not assume that the power bank delivers 10,000mAh output. Instead of 10,000mAh output, the power bank offers you 7400 mAh (3.7x 10000/5) result.

3. Power bank output efficiency

The companies manufacture the power bank with a capacity of 5,000mAh, 10,000mAh and 20,000mAh. Most people think the power bank will deliver the same result as mentioned in the specs. But in fact, they don’t get the full power juice from the power bank, to consider you will get only ⅔ output out of the power bank.

For example, it is expected that a power bank with a capacity of 10000 mAh will charge a smartphone of 3500 mAh 2.8 times. But they ignore the important point. That is a loss of power.

Actually, 10000 mAh power bank will give you only 7,400 mAh output. Actual output means.

For a 10,000mAh power bank – 3.7 X 10,000 / 5 = 7,400 mAh. So the 3.7V 10,000 mAh power bank actually only delivers 7,400 mAh output on a 5V USB connection.

Before you buy a power bank, consider that the power bank must can charge your phone at least two times.

4. Input charging support:

Power banks come with a larger battery and need to charge themselves. Charging the external battery takes a few hours or more. If the best power bank supports a 1 amp charger.

When purchasing the power bank, consider purchasing the best power bank that supports fast charging. Most power banks come with 2.1 Amps charging stands, but nowadays power banks have a fast charge feature. So consider buying a better power bank with fast charging.

It is good for the user to have a Type C port in the Power Bank, which then helps the power bank to recharge quickly.

5. Safety and protection layers

For safety, you need to think about the layers of protection and circuit design of the best power bank. Modern power banks come with protective layers like short circuit, short circuit control, temperature control, input and output overvoltage protection.

Safety is the power is the most important because some users are not aware of the technical specifications of the power bank and even they don’t know how to charge the power bank.

Make sure the power bank has layers of protection or safety protection such as short circuit, short circuit control, temperature control, input and output overvoltage protection. Protective layers help the best power bank reduce the risk of crawling. Before buying the best power bank, consider buying the power bank with reputable bands.

Three reasons that can cause the power bank to explode :

  1. Bad battery quality:

The function of the power bank depends on the quality of the battery. Therefore, the power bank must have a quality battery. This is the most important factor that can cause a battery to explode.

Excellent quality batteries cost manufacturers more, which is why some companies use cheaper lithium ion batteries to lower the cost of producing the best power bank.

This creates a potential risk to their safety. Most companies used lithium ion batteries and lithium polymer batteries for power banks, which are good for power banks.

  1. Design of incapable circuits:

Another reason for the explosion was the internal circuit design of the power bank. The design of the internal circuit may affect the performance of the external battery.

Good circuit design ensures that they equip the power bank with circuit protection, which is important for the safety of the best power bank.

This protection includes short circuit, short circuit control, temperature control, input and output overvoltage protection. If the circuit design does not meet battery safety standards, there is an increased risk of the best power bank exploding.

  1. Improper Usage:

Improper use of the power bank is one of the factors which cause the power bank to explode.

why the power bank explodes.

Improper handling of the battery can expose the battery to high temperatures and other hazardous environments.

Spilling water on the battery or accidentally placing it in a heated place can lead to unfortunate accidents.

The battery will be overcharged, especially if the best power bank does not have a power protection feature with a battery.

6. Build quality and Material used for the Power bank

The ABB or metal body is the best choice for the best power bank. So consider the power bank has built with this material. The body material is matters because the material makes them lightweight and looks good.

7. Lithium-ion vs lithium polymer

There are two types of batteries available in the market: lithium-ion and lithium-polymer.

The question comes to my mind: which is better? Lithium-ion or lithium-polymer.

A lithium-ion battery cell is a type of rechargeable lithium-ion battery. On the other hand, lithium polymer battery cells are packaged in a soft pouch which weighs less than lithium ion cells.

Lithium-ion power banksLithium-polymer power banks
Energy densityHighLower
Explosion riskExpected to explode on overchargeSafer from explosion
AgingLoss of capacity over time, even when not in useShort life
Size and weightLittle heavy and thickLightweight and compact size
PriceLowest priceExpensive
Conversion Rate85% to 95%75% to 95%

According to the above table, the advantages of lithium polymer batteries are more numerous and they come with safe protection and compact size which enhances the power bank.

Lithium polymer is expensive, but it is a better choice than lithium ion batteries.

8. The number of ports

When you buy the power bank consider having at two output USB ports and must have Type-C ports. Type-C is the latest technology that supports fast charging.

Two USB Output ports help you charge two devices simultaneously, hence consider buying the best power bank that has at least two USB output ports.

9. Size & weight

The best power bank should have a light and compact size. It makes it easy to carry anywhere, you can also keep it in your pocket or bag.

Lithium-polymer batteries make the best power bank lighter and smaller, so buy a lithium-polymer power bank.
