Smartphone is the most trustful companion in every person’s life. Smartphone gets our lives more simple because it gives us the chance to stay connected, to keep in contact with the rest of the world and it is fun for us. Smartphones can stop to work, though. And that happens in the worst moment as possible. There is a solution, and it is necessary nowadays: power banks are the fundamental accessory to use smartphone without anxiety. With power banks we can completely recharge our smartphone more than once a day, without having to plug it to the power. How do we choose a power bank?
Aesthetics and comfortability are important, but are there any other essential features? Here are every thing you must know to choose the right power bank for you.
What dimension does a power bank need to have?
We’re not talking about the power bank’s physical dimension. What matters is the power bank’s power in amperage: we refer to the maximum recharge capability of the battery. “mAh” is the abbreviation to “milliAmpére/hour”: it indicates a rechargeable battery capability over time. Common power banks start from 2.000 mAh: this means they can transfer to the smartphone a 2.000mA stream continuously for one hour. The higher is this value and the more powerful is the battery, the longest is the battery lasting. During a recharging session there’s a light electric power leakage, approximately of 20-30% less than the declared value.
How to recharge a smartphone with a power bank
Amperes indicated in a power bank USB output port determine the device speed of recharging. You need to control the output electric stream indicated on the charger of your device in order to choose the right power bank. Normally a smartphone battery charger delivers about 1A stream power: it is ideal to recharge it with a power bank with a 1A output. Nothing forbids you to use a power bank with a higher output value, because outgoing stream is controlled by electrical tension, which is always 5V, a value expressly expected on USB ports specifications.
How to recharge a power bank
A power bank can be recharged by a power source like a laptop, a wall battery charger or a USB cable. The recharging time of a power bank depends not only on its capacity but also on the stream accepted by the input. You need to control that amperage of input ports is indicated correctly in order to choose the right power bank. This way you can estimate the necessary time to the complete recharging.
How many USB ports does a power bank need to have?
Another thing you need to consider before you choose a power bank is the number of devices you wish to recharge. Generally, power banks with a higher capacity have more than one USB port, so they can allow you to recharge more than one smartphone in the same time: maybe your personal smartphone and your work smartphone. You can also choose to recharge your smartphone together with a tablet. A tablet has a higher output value, though, so you need to ensure that power banks have the requested capacity and recharging features we described earlier.
Which cables can you use to recharge your smartphone with a power bank?
When you purchase a power bank, it should have a recharging cable included. The cable connects the power bank through its input port (usually, it is a Micro-USB port) to a power source with a standard USB port. Some power banks have a LED indicator alerting you when it is exhaust, the power level and when you need to recharge it. The cable to recharge your smartphone is not always necessary: if your device is connected with Micro-USB, you can use the same cable, or the one with your smartphone.
What about power banks safety?
It is recommended to register your bank with a serial number given to you at the moment of the purchase, in order to avoid counterfeiting. Check the warranty as well: different producers, countries of origin or types of battery could have substantial differences on the warranty period. The printing on the package or on the instructions usually solves this problem.
To last the longest as possible, a safe power bank should not overheat itself or leak too much energy, while it’s working
What about power bank aesthetics and comfortability?
The most appreciated power banks are those expressing originality and an aesthetic sense. They simply fit in your pocket, they are easy to travel with because they are compact and thin. Power banks could be the perfect accessory for a company because they can become a useful promotional gadget: customize your power banks with your logo!
