How to choose the right power bank

Smartphones and tablets make life so much easier.That is ,until they run out of juice when there’s nowhere to plug in. Then all you need to do is “Charge”!But wait, you see. What if there is no a wall outlet nearby? Well, this is exactly the time to have a portable USB power pack charger.
Besides price, there are a number of things to consider while choosing a portable power bank charger. Here are some tips to help you find the charging partner that’s right for you.

Capacity

To do that, you’ll need to know the energy capacity of the device you’ll be charging. Once you know your device’s capacity, just check out whatever portable power bank you’re looking into and see what its own mAh capacity is.
Bigger numbers mean more power and more recharges for your smartphone, or charging for bigger devices that need more power.
For examper ,the iPhone 7, has a 1960mAh battery, while Android smartphones like the Samsung Galaxy S8 are usually between 2000 and 3000mAh. As long as your portable charger comfortably exceeds that number, you’ll get at least one full charge out of it.
iPads and other tablets, however, are a different story. With the latest iPad Pro sporting a 10000mAh+ battery, you’ll need a much higher capacity pack for even one full charge.

Size and Weight

Usually size and weight increase with capacity.
It’s fine if you’re going on a camping trip and plan to have your car nearby to store stuff. When it comes to daily use.If you commute on foot or happen to be a student who walks to and from classes, a smaller charger would be a better option for backup power.

Charging Time

Solar-based chargers, for example, may be nice to have when camping for a long time but many typically take a long time to charge devices and run out of power pretty quickly. Fast chargers also aren’t just great for charging up a phone in a jiffy, they’re also good at charging devices with larger batteries such as tablets.


USB Ports

Check that each of those ports is rated for the device you’re plugging into it.
And a mattter of how many devices you need to charge.

Generally, bigger batteries with more mAh will have more USB port.
With multiple ports, simultaneous charging is super-easy.


Safety and Quality

Safe power banks should have undergone the following testing.

Efficiency more efficient power bank is, a lower operating temperature it will have, which wastes less energy for a longer life expectancy.


Over Current Protection it prevents too much power going into the battery pack and the power going out to the connected equipment, protecting the delicate circuitry of both devices.

Over Voltage Protection it protects both the power bank and the connected device by keeping the voltage within recommended safety parameters to avoid damage.

Over Discharge/Charge Protection some power banks consistently monitor charge states to prevent this from happening.

Heat Tests at Extreme Temperatures While using batteries in extreme temperatures isn’t advised anywhere.
