While you are out from your home, your phone gets low battery and there is no outlet to plug your phone, what will happen. Don’t worry, there are Power banks which could save you the day. But you should know how to pick the best power bank and what are the things to consider when buying a power bank.
The power bank is a portable charger that can supply power through its USB ports. Power banks include a built-in battery to do that. Generally, Power banks using to charge mobile phones, tablets, and other devices with USB ports like lights, speakers, small fans, cameras. But, most of the time mobile phones and Tablets are charging with this. Power banks include a Control Circuit which could manage the charging of the battery and converting its voltage to 5 volts for the USB port.
When you buying a Power bank, there are things to consider before that. In this article, we will bring you those tips and factors.
1. Capacity
The capacity is typically expressed in Milliamp Hours (mAh). It describes the amount of electrical energy the device can hold. So, a power bank with high mAh s can hold enough energy that can power up devices like, mobile phones, tablets, and others we mentioned before. Generally, power banks start around 2,000 mAh and it could go all the way up to over 20,000 mAh.
Generally, smartphones have a battery capacity of 3,000 mAh. So, when you buying a power bank, you must surely go for an over 3,000 mAh battery pack. Because none of the power banks will deliver their advertised mAh capacity due to the power loss. The ratio of power loss could be from 15% to 30%.
You should try to find a power bank that can completely charge your smartphone at least twice. Due to the power loss, we recommend you to buy a power bank over 9,000 mAh for multiple charging.
2. USB output ports and speed
Before all, you have to check whether your device can accept the current coming through the USB outputs in power banks. Today, most of the devices are compatible with 2 Ampere (A) current. Typically, power banks have either 1 A or 2 A output USB ports. Both will be running at the standard 5 volts. 1 A output for standard charging and 2 A output for faster charging. 2 A ports not only charges your device faster; it will also keep it running while it’s connecting to the power bank. But in newest power banks have USB output ports with more than 2 A, like 2.4 A, and 3 A and 5 A which are USB-C type ports. In 2021, It’s good for you to go with a power bank that has a minimum of 2 A USB output.
We think capacity and Number of USB ports, speed are the main things to consider when buying a power bank. But it’s good to look at the following factors also after the above 2 main things.
3. Performance of the power bank
Most of the power banks will take 1-2 hours to charge smartphones fully. But this could vary according to the brand. And you should also consider how long it will take to charge your power bank. You can get access to these details from the product’s official website.
4. Overcharge protection
This safety feature will keep power banks from being overcharged than their capacity. Indeed, it’s an integrated circuit that helps to avoid battery’s overcharging. Today, almost every branded power banks have over-temperature protection, short circuit protection, besides having this feature. Overcharging may cause power banks to explode. So, you have to make sure and buy power banks from reputable brands.
5. Warranty coverage and Customer reviews
It’s good to buy a power bank that has warranty coverage at least for 6 months. Not only that, but you should look over the customer service of the product also. Referring to customer reviews will help you to understand the experience people received by using the specific power bank. Those reviews will help you to make the decision before buying the power bank you desired.
6. Size and weight
High capacity power banks are generally having a large size and substantial weight. When you are only out for one day, a 9000 mAh power bank may be enough. But, if you are away from power for more than 2 days like hikes, trips, 2000 mAh power banks are a handy option. But those would be too big for your pockets.
7. Power Indicator
